Free VPNs promise to protect your privacy. The documented evidence — from academic studies, cybersecurity research, and real data breaches — shows that most of them do the exact opposite. They collect your browsing history, sell it to advertisers, embed tracking libraries in their code, and some have leaked hundreds of millions of user records from databases they were never supposed to have. This article names names, cites sources, and tells you what the research actually says.

What if the privacy tool you downloaded specifically to protect yourself from data collection is itself the most active data collector on your phone? What if the app claiming to hide your browsing activity from your internet provider is simultaneously logging those same sites and selling the list to data brokers? What if the service promising to make you anonymous on the internet is owned by an opaque company in a country with no user privacy protections — a country that has the legal authority to demand and receive everything that company collects? This is not a hypothetical scenario. It is the documented reality of a large proportion of the free VPN industry — and this article names the specific apps, cites the specific research, and explains exactly what happened to the data of 360 million users who thought a free VPN was protecting them.

☑️ PRECHECK — What You Need to Know Before Reading This Article
This article covers free VPN apps specifically — not all VPN services. "Free VPN" here means apps that advertise themselves as completely free to download and use permanently, not premium VPN services that offer a limited free trial. Not every free VPN is a data-harvesting nightmare — this article specifically identifies the exceptions (ProtonVPN free tier, Windscribe) that independent researchers consistently rate as genuinely trustworthy. This article names specific VPN services where there is documented, published evidence of the practices described. These are not opinions — each named criticism is linked to published cybersecurity research or news reports. Daily Reality NG has no affiliate relationship with any VPN service mentioned in this article, paid or free. Information verified July 14, 2026.
🔑 Key Decisions This Article Helps You Make
Whether to keep using your current free VPN
By the end of this article, you will know the specific warning signs that indicate your current VPN is harvesting rather than protecting your data.
Whether any free VPN is worth trusting at all
The honest answer is nuanced — this article identifies the specific exceptions that are genuinely trustworthy and explains why they are different.
What permissions to check before granting to any VPN app
A concrete permissions checklist that helps you identify risky apps before installation — not after your data is already collected.
Whether your existing data has been exposed in documented breaches
How to check whether your email address appears in known VPN data breaches — with a specific tool to verify.
How to verify whether your VPN is actually working
The specific tests — DNS leak, IP leak, WebRTC leak — that tell you whether your VPN is protecting you or exposing you.
What alternative options exist if you cannot afford a paid VPN
The verified legitimate free options and the alternatives (browser-based protection, ISP negotiation) worth considering.
Adaeze downloaded a free VPN in 2022 because she wanted to access a streaming service not available in Nigeria. The app had 50 million downloads, a 4.2-star rating, and a homepage that promised "military-grade encryption" and "zero data logging." She kept it installed. Used it regularly for two years. Felt safer with it than without it.
In 2023, security researcher Jeremiah Fowler discovered an open, unprotected database on the internet containing 360,308,817 records — 133 gigabytes of user data — from the same type of free VPN app that millions of people like Adaeze were using. The database contained email addresses, original IP addresses (the real ones the VPN was supposed to hide), geolocation data, and records of the specific websites users had visited. The app's homepage still advertised zero data logging.
Adaeze's app was not necessarily the one in the breach. But the breach illustrated what independent cybersecurity research had been documenting for years: the free VPN industry operates on a fundamental economic paradox. Running VPN servers costs money. If users pay nothing, the money must come from somewhere. And in the majority of documented cases, that somewhere is the users' own data — the very data the VPN was installed to protect.
This article is the complete, documented answer to what that actually means — for your browsing history, your IP address, your device data, and your privacy.
You Downloaded It for Privacy. The Research Says It May Be the Least Private App on Your Phone.
You found the app on the Play Store or App Store. The name had words like "Secure," "Private," "Shield," or "Guard" in it. The reviews were mostly positive. It was free. You needed to access something blocked in Nigeria, or you wanted a bit more privacy on public Wi-Fi, or someone in a group chat recommended it. You granted it the permissions it asked for without reading them carefully. You have been using it ever since.
What you may not know: 43% of VPN users globally are subscribed to free services (Security.org). The top free Android VPN apps collectively have hundreds of millions of downloads. And a major, peer-reviewed academic study found that 67% of free VPN apps had tracking libraries in their code. A new July 2026 study found that 29 out of 281 free Android VPN apps were actively leaking user traffic. If you have never verified your VPN's data practices against independent research — this article is that verification.
Quick Answer — What Free VPNs Actually Do With Your Data
Most free VPNs monetise the data they collect from users in one or more of these ways: selling browsing history and IP data to advertisers and data brokers; embedding third-party tracking SDKs from companies like ByteDance and Yandex; injecting advertising cookies into your browser; selling your unused bandwidth to other companies; or operating with no meaningful encryption at all. The evidence comes from academic studies (CSIRO/UC Berkeley/UNSW), independent investigations (Top10VPN, Zimperium), and documented real breaches (SuperVPN: 360 million records exposed). A small number of free VPN tiers from legitimate paid providers (ProtonVPN, Windscribe) are genuine exceptions — they fund their free tier through paid subscriptions and do not monetise user data. The rule of thumb remains: if the product is free and privacy is the product's purpose, ask how the company is actually making money. The answer usually explains what is happening to your data.
"If the VPN is free and privacy is the promise,
your data is almost certainly the actual product."
According to Daily Reality NG research and primary source verification (July 14, 2026): free VPN usage in Nigeria has grown significantly as internet users seek to access geo-restricted content, circumvent periodic network disruptions, and protect data on public Wi-Fi networks. The challenge specific to the Nigerian context is that many of the most popular free VPN apps available on Nigerian app stores are precisely the category that independent research has most thoroughly documented as privacy-compromising. The apps with the highest download counts and most prominent placement in app store search results are not necessarily the safest — and the marketing language of "military-grade encryption" and "zero logs" has been directly contradicted by documented breaches in multiple cases.
Daily Reality NG analysis of the verified research confirms: the free VPN problem is not a fringe issue. A July 2026 study of 281 free Android VPN apps — published three days before this article's update — found that 24 apps that together account for approximately 360 million installs were leaking DNS requests that expose visited websites to local network operators. For a Nigerian user on a mobile network, this means their ISP can see which websites they are visiting despite the VPN being active. The encryption promise is being broken silently. This article documents the mechanism, the evidence, and the alternatives — in the plain, verified, source-cited language that Daily Reality NG is built on.
🚨 Did You Know — A Single Free VPN Breach Exposed 360 Million Records Including Your Visited Websites
Security researcher Jeremiah Fowler discovered a publicly accessible, password-free database containing 360,308,817 records totalling 133 gigabytes of data connected to the free VPN app SuperVPN. The data included email addresses, original IP addresses (the ones the VPN was supposed to hide), geolocation data, unique user identifiers, device models, operating system information — and critically, references to specific websites that users had visited. SuperVPN's published privacy policy claimed it kept "no logs." The database directly contradicted this claim. SuperVPN had 100 million combined downloads on Google Play and the App Store at the time of the breach. This was not SuperVPN's first security incident: it had been flagged as malware-rigged in 2016, had man-in-the-middle attack vulnerabilities in 2020, and was part of a 21 million record breach in 2022. Both apps linked to China. Source: CPO Magazine, June 2023; VPNMentor; Jeremiah Fowler's original disclosure.
What a VPN Is, What It Is Supposed to Do, and Why the Free Version Changes the Equation Completely
Understanding the free VPN problem requires understanding what a VPN is actually supposed to do — and then understanding the economic reality that makes it nearly impossible for a genuinely free service to deliver that promise honestly.
What a VPN Actually Does, What It Cannot Do, and Why the Business Model Determines Whether It Helps or Harms You
What a VPN is supposed to do: A Virtual Private Network (VPN) creates an encrypted "tunnel" between your device and a server operated by the VPN provider. All your internet traffic is routed through this tunnel. From the perspective of your Internet Service Provider (ISP) — your MTN, Airtel, Glo, or 9mobile in Nigeria — they see that you are connected to a VPN server, but they cannot see what you are doing through it. Websites you visit see the VPN server's IP address rather than your own. This provides two main benefits: your ISP cannot see your specific browsing activity, and websites cannot identify your real geographic location from your IP address.
What a VPN cannot do: A VPN cannot make you anonymous to services you are logged into. Google still knows you are you when you sign into Gmail regardless of which VPN you use — you identified yourself with your credentials. It cannot prevent cookie tracking across websites. It cannot stop browser fingerprinting (where websites identify your device by its specific configuration). It cannot protect you from malware in files you download. It cannot prevent phishing. A VPN is one layer of privacy protection in a multi-layer security picture — not a complete privacy solution.
The economic reality of free VPN services: Running a VPN infrastructure costs real, significant money. Server hardware or cloud hosting costs. Bandwidth costs at scale. Staff costs for technical operations and security. A premium VPN with thousands of servers across dozens of countries can cost tens of millions of dollars annually to operate. A service with no subscription revenue must fund these costs another way. The three primary models documented by research: (1) Showing ads — requires collecting enough data about users to target those ads or counting on volume regardless of targeting. (2) Selling user data to data brokers and advertisers — the most profitable and most damaging model. (3) Selling user bandwidth — turning users' devices into nodes on a peer-to-peer network as Hola VPN did with Luminati. Any combination of these is possible in a single free VPN service.
Why the business model determines whether a free VPN helps or harms you: A VPN that earns revenue from your data is not a privacy tool — it is a data collection tool with a privacy interface. The encryption tunnel that hides your activity from your ISP delivers that same activity directly to the VPN provider instead. If the VPN provider then sells that data to the same category of companies your ISP might have sold it to, you have changed which entity is surveilling you — not whether you are being surveilled. This is the fundamental insight that makes the free VPN question more than a casual concern about app quality.
The Six Documented Ways Free VPNs Monetise You — Each Confirmed by Named Research
These are not theoretical risks or industry generalisations. Each practice below is documented in named academic studies, security investigations, or published privacy policy analyses — with the source identified for every claim.
| Practice | How It Works | Named Example | Evidence Source | Severity |
|---|---|---|---|---|
| Selling browsing data to data brokers and advertisers | VPN logs which websites you visit, how long you stay, what you search for — then sells this as an advertising data product. Your browsing profile becomes a commodity. | Psiphon: Revenue estimated $2.2M+ annually from sharing data with advertising partners who track internet usage. Confirmed in their own privacy policy. | TheBestVPN.com analysis of published privacy policies; Betternet analysis | 🔴 Critical — directly defeats the purpose of a VPN |
| Embedding third-party tracking SDKs in the app | Third-party software development kits (SDKs) from advertising companies are embedded in the VPN app's code. These SDKs collect device and usage data and send it to their parent companies independently of the VPN company. | Betternet: CSIRO found it had the highest number of tracking libraries of any tested free VPN — 14 in total. Including advertisers who track and log user data. | CSIRO/UC Berkeley/UNSW academic study; TheBestVPN.com | 🔴 Critical — tracking occurs at the SDK level, often undisclosed |
| Selling user bandwidth to third parties | Free users' unused internet bandwidth is enrolled in a peer-to-peer network and sold to paying customers. These customers then use the free VPN user's IP address for their own internet traffic — including potentially criminal activity. | Hola VPN (152M+ users): Sold user bandwidth through sister company Luminati (now Bright Data). Users' IPs used for others' traffic including criminal uses. Documented by multiple security researchers. | The Next Web; multiple independent cybersecurity investigations | 🔴 Critical — you may be legally liable for traffic sent through your IP |
| Injecting ads, cookies, and tracking pixels | The VPN intercepts your unencrypted traffic and injects advertising cookies, tracking pixels, and web beacons into web pages before they reach your browser. This identifies you to advertisers and tracks you across sites. | TouchVPN: Known for injecting ad cookies, tracking pixels, and web beacons into browsers. Documented in PrivacySavvy analysis. | PrivacySavvy.com; TheBestVPN.com | 🔴 Critical — actively introduces tracking to traffic it should protect |
| Redirecting traffic through undisclosed affiliate networks | The VPN redirects specific website traffic through affiliate partner networks, earning referral revenue when users visit certain sites. This is done without user knowledge or consent. | HotspotShield: CSIRO found it redirected user traffic to Alibaba.com and eBay.com through partner networks Conversant Media and Viglink. Claimed a "no-log" policy while logging IP addresses. | CSIRO academic study; Max Browser citing Hotspot Shield investigation | ⚠️ High — undisclosed affiliate monetisation undermines trust |
| Sharing data with opaque company affiliates | Free VPN collects user data and shares it with affiliated companies in the corporate structure — which may include entities in different jurisdictions with weaker privacy protections. | Opera VPN: Privacy policy confirms data sharing with third-parties and marketing partners, allows advertisers to track. ZPN: Shares logs with affiliated companies. Both confirmed in published privacy policies. | TheBestVPN.com analysis of Opera and ZPN privacy policies | ⚠️ High — data reaches entities with no user-facing accountability |

The Major Free VPN Data Breaches — When "No Logs" Claims Were Directly Contradicted by the Evidence
The SuperVPN breach (May 2023): 360,308,817 records exposed. Security researcher Jeremiah Fowler discovered a publicly accessible database with no password protection, containing 133 gigabytes of data linked to SuperVPN — a free app with 100 million combined downloads across Google Play and the Apple App Store. The exposed data included: user email addresses, original IP addresses (the real location data the VPN was supposed to hide), geolocation records, unique user IDs, device models, OS versions, VPN server connection records, internet connection type, and — most damningly — links to specific websites that users had visited. SuperVPN's published privacy policy stated explicitly: "SuperVPN keeps no logs which enable interference with your IP address, the moment or content of your data traffic." The breach directly contradicted this claim. Both SuperVPN apps were linked to companies in China. Fowler noted the terms of service contained clauses about "subverting state power" and "undermining national unity" — concerning language for a privacy tool. This was SuperVPN's fourth documented security incident across 2016, 2020, 2022, and 2023.
The 2022 breach: SuperVPN, GeckoVPN, and ChatVPN — 21 million records. A network of three free VPN services shared a publicly accessible database that exposed 21 million user records. Exposed data included email addresses, payment information, device IDs and serial numbers, full names, and country information. Again, multiple services in this group operated public "no-logs" claims while maintaining the exact records they denied keeping.
The 2020 breach: 20 million VPN users' data exposed. Records of approximately 20 million users across multiple free VPN services — all of which publicly claimed no data collection — were found exposed online. The pattern was consistent: free services claiming zero logging were maintaining detailed user records while denying it in their marketing.
Why these breaches matter beyond the individual apps: The breaches reveal two distinct but equally serious problems. First: many free VPNs are maintaining detailed logs while claiming not to. This creates a gap between the privacy promise and the privacy reality that users cannot detect by using the app normally. Second: even when data collection is genuinely unintentional from a fraud perspective, the security practices of free VPN providers are demonstrably weaker than those of paid providers. The SuperVPN database had no password. It was accessible to anyone with an internet connection. The data it should not have had was accessible because security investment was insufficient — the kind of investment that requires subscription revenue to fund properly.

💡 Did You Know — A July 2026 Study Found 24 Free VPN Apps Leaking DNS Requests With 360 Million Combined Installs
A new study of 281 free Android VPN apps, published by The Hacker News just three days before this article's update (July 11, 2026), found that 24 apps that together account for approximately 360 million installs were leaking DNS requests — meaning they were exposing which websites users visited to local network operators (including ISPs and mobile network operators) despite the VPN supposedly being active. Additionally: 6 apps leaked full browsing traffic outside the tunnel; 4 ran "tunnels" with no encryption at all; 76 apps sent the device's Advertising ID (a unique code advertisers use to track users across apps) to third parties; and 169 apps made no attempt to disguise VPN traffic, making them easily identifiable by ISPs and government censors. For Nigerian users specifically: DNS leaks mean your mobile network operator (MTN, Airtel, Glo, 9mobile) can see which websites you are visiting despite the VPN being on.

The Free VPNs That Independent Researchers Actually Trust in 2026 — And Exactly What Makes Them Different
ProtonVPN Free — the strongest case for a genuinely private free VPN: ProtonVPN is operated by Proton AG, headquartered in Geneva, Switzerland — under Swiss law, which provides some of the world's strongest privacy protections and places Proton outside the 5-Eyes, 9-Eyes, and 14-Eyes intelligence alliances. ProtonVPN's free tier has no bandwidth limit, is backed by an independently verified no-logs policy (third-party security audit), and is open-source (the code is publicly available for anyone to inspect). The free tier funds through paid ProtonVPN Plus subscribers — Proton's business model requires no monetisation of user data. Free users get slower speeds and access to fewer server locations (3 countries vs 90+ for paid), but the core privacy protections are identical to the paid tier. ProtonVPN was built by the same team behind ProtonMail — the encrypted email service used by journalists and activists globally. This context matters: ProtonVPN was designed from first principles by a team whose core mission is privacy, not data monetisation.
Windscribe — the legitimate Canadian alternative: Windscribe is a Canadian company offering 10GB of free data per month — generous enough for moderate everyday use. Their privacy policy is notably transparent about what they collect (minimal) and what they do not (browsing activity, connection logs). They have published independent security audits. Their business model is subscription-driven — the free tier exists to convert users to paid plans. Windscribe's free tier includes access to servers in 10 countries. The limitation versus ProtonVPN free is the 10GB monthly data cap and fewer server locations for free users. For heavy VPN users, this will not be sufficient — but for privacy-focused use with moderate data volumes, Windscribe free is a legitimate option.
What makes these different from problematic free VPNs: Three fundamental characteristics distinguish legitimate free VPN tiers from data-harvesting ones: (1) The business model does not require user data monetisation. Both ProtonVPN and Windscribe make money from paid subscriptions. There is no incentive to collect and sell data. (2) Their no-logs policies have been independently verified by third-party security audits — not just self-certified by marketing departments. (3) Their company structures are transparent, their jurisdictions are identifiable, and their ownership is public. You know who runs these services, where they are based, and what law governs them. Contrast this with the SuperVPN apps that listed different developers on different app stores and had opaque connections to Chinese entities. The opacity is not incidental — it is how data harvesting businesses avoid accountability.
The critical caveat on all free VPN tiers: Even the most trustworthy free VPN tiers have limitations that affect how useful they are. ProtonVPN free tier servers are slower because free users share server capacity with less priority than paid users. If you are using a VPN for high-bandwidth activities (streaming, large downloads), free VPN tiers from legitimate providers will typically disappoint on speed. This speed-privacy trade-off is the honest version of the free VPN equation — as opposed to the dishonest version where you get good speeds but your data is being sold.
"The free ones are in the business of data collecting; their VPNs are just the fishing nets they use to gather the data they need to sell. Good VPNs use the best encryption and tunneling protocols available. The free ones cut costs on exactly the things that make a VPN safe."— PrivacySavvy.com — Free VPN analysis, December 2024
📋 Reader Situation Snapshot — Which VPN Category Describes Your Current Situation?
| Your Current VPN Situation | Privacy Risk Level | What Your Data May Be Used For | Recommended Action | Cost |
|---|---|---|---|---|
| Using a popular free VPN app with no known audit (random app store download) | 🔴 High — no independent verification of data practices | Likely: browsing history sold to data brokers; device ID sent to third-party ad networks; possible DNS leaks exposing visited sites to ISP | Check whether your VPN is in known research flags at Top10VPN.com. If so, switch to ProtonVPN free or Windscribe immediately. | Free to switch |
| Using a VPN named in this article's documented offenders section (Hola, Betternet, SuperVPN, HotspotShield free, etc.) | 🔴 Very High — documented problematic practices | Documented: data sold to advertisers; bandwidth sold to third parties (Hola); traffic redirected through undisclosed affiliate networks; tracking libraries active | Delete immediately. Switch to ProtonVPN free tier or Windscribe free. Check haveibeenpwned.com for your email address against known breaches. | Free to switch |
| Using ProtonVPN free tier | ✅ Low — Switzerland-based, independent audit, open-source | No browsing data sold. No-logs policy independently verified. Business funded through paid subscriptions, not data. | Continue. Be aware of speed limitations on free servers. Consider upgrading to paid tier if speed is a priority. | Free (or upgrade from ~$4/month) |
| Using Windscribe free (10GB/month) | ✅ Low — Canadian jurisdiction, transparent policy, audited | Minimal data collected and not sold to third parties. Funded through subscriptions. | Continue. Monitor your monthly data usage — 10GB may be insufficient for heavy use. Consider paid plan for unlimited data. | Free (or upgrade from ~$3/month) |
| Using a paid VPN subscription (NordVPN, ExpressVPN, Surfshark, etc.) | ✅ Low-Medium — subscription model removes data-sale incentive | Paid VPNs have experienced breaches (NordVPN 2018 single server incident; ExpressVPN RDP bug) but limited exposure due to actual no-logs policies. Subscription revenue removes incentive to sell data. | Verify your VPN has a current independent security audit (most major paid VPNs publish these). Check for DNS leaks at dnsleaktest.com. | Typically $3–$12/month |
| No VPN — considering getting one | ⚠️ Context-dependent — depends on what you use the internet for | Your ISP can see your browsing activity. Your real IP is visible to websites. But you are not at risk of a VPN provider mishandling your data. | If you need a VPN: start with ProtonVPN free. If you consistently need it: a paid subscription from a reputable provider is the most reliable option for genuine privacy protection. | ProtonVPN Free = ₦0 |

✅ Did You Know — ProtonVPN Free Is the Only Free VPN With No Bandwidth Limit, No-Logs Audit, and Open-Source Code
Among all free VPN options currently available, ProtonVPN's free tier is the only one that simultaneously offers: no bandwidth limits (you can use it as much as you want per month); an independently audited no-logs policy (third-party security firms have verified the claims); open-source client code (anyone can inspect the application to verify it does what it claims); and a Switzerland-based jurisdiction outside all major intelligence alliances. The limitation is speed — free users get access to servers in three countries (United States, Netherlands, Japan) and are lower priority than paid users, meaning slower speeds. But for occasional privacy-conscious use — banking on public Wi-Fi, accessing geo-restricted sites, or protecting your data on shared networks — ProtonVPN free tier is the only option the independent research consistently validates as genuinely trustworthy at zero cost.

How to Evaluate Any VPN Before Installing It — A Verified 8-Point Checklist
Use this checklist before installing any VPN app on your phone or computer. Every point is based on verified research into what distinguishes safe VPNs from data-harvesting ones. This takes 10 minutes and could save your browsing history from being sold to data brokers.
| Check | What to Look For | Green Flag | Red Flag | How to Verify |
|---|---|---|---|---|
| 1. Company Jurisdiction | Where is the VPN company legally registered and operating from? | ✅ Switzerland, Iceland, Panama, British Virgin Islands — strong privacy laws | ❌ China, Russia, or opaque/unknown company structure | Search the company name + "headquartered" or check their About/Legal page |
| 2. Business Model | How does the company make money? | ✅ "We earn through paid subscriptions and premium upgrades" | ❌ "Marketing partners," "advertising technology," or vague references to "third parties" | Read the revenue model section of their website and privacy policy |
| 3. No-Logs Policy | Does the VPN claim not to log user activity? | ✅ Audited no-logs policy from a named third-party security firm with the audit published | ❌ Self-claimed "zero logs" with no third-party verification — the SuperVPN breach directly contradicted a self-claimed no-logs policy | Search the company name + "security audit" or "no-logs audit" |
| 4. App Permissions | What does the app request access to on your device? | ✅ VPN profile permission only (essential for function) | ❌ Camera, microphone, contacts, call logs, precise location, SMS — none of these are needed for a VPN to function | Check on installation before granting permissions. On Android: Settings → Apps → [VPN name] → Permissions |
| 5. Developer Transparency | Can you identify who built and operates this app? | ✅ Named company, identifiable individuals, verifiable address or registration | ❌ No developer website, no contact information, different developer names on different app stores (as with SuperVPN) | Check the app store listing for developer details.

Real-World Impact — What Free VPN Data Collection Has Actually Cost Users
These are not theoretical risks. They are documented real-world consequences of the practices this article describes.
360 Million People Had Their Real IPs Exposed
SuperVPN's 2023 breach exposed the original IP addresses — the real, geolocatable identifiers the VPN was supposed to hide — of 360 million users. Some of those users were in countries where their online activities could result in legal consequences. The VPN promised to protect them. The open database proved otherwise.
A Hola VPN User's IP Was Used for Criminal Activity
The documented risk of Hola's bandwidth-selling scheme (Luminati) was not hypothetical — Hola's system was used to conduct DDoS attacks and other criminal activity through users' IP addresses. The free users who "donated" bandwidth were unknowingly participants in activities they did not authorise.
Kaspersky: 2.5× Rise in Malicious VPN Apps Q3 2024
The rise in VPN popularity — driven partly by privacy awareness — has been directly exploited by malicious actors. Kaspersky documented a 2.5× increase in users encountering malicious apps posing as free VPNs in Q3 2024. Privacy concern is being weaponised to deliver malware to exactly the people trying to avoid it.
360M Installs Were Leaking DNS Requests to ISPs
The July 2026 study found that 24 free VPN apps with combined installs of approximately 360 million were leaking DNS requests — meaning their users' mobile network operators could see exactly which websites they visited. These users believed they had privacy. The VPN created the feeling of protection without the reality.
Betternet Generated Revenue From 38M Users' Data
With 38 million users and 14 confirmed tracking libraries in its code, Betternet represented a data collection business disguised as a privacy product. The users generated no revenue through subscriptions — they were the product. Their browsing data, device identifiers, and usage patterns were the inventory being sold.
⚡ 24-Hour Action — What to Do With This Information Today
- 1Identify which VPN you are currently using. Open your phone's Settings → VPN (or the VPN app itself) and note the app name and developer. Search "[VPN name] + data practices" or "[VPN name] + security audit" to find independent coverage of its privacy record.
- 2Check your email against known breaches. Visit haveibeenpwned.com and enter the email addresses associated with your VPN account(s). The service checks your email against all known data breach databases and shows you if you appear in any documented leaks — including VPN provider breaches. Free, takes 30 seconds.
- 3If you are using any VPN named in this article's documented offenders section, delete it today. Specifically: if you have Hola VPN, SuperVPN, Betternet, TouchVPN, HotspotShield (free tier), or Opera VPN installed — delete them. Your data security while using these apps cannot be verified as protected.
- 4Install ProtonVPN free tier as a replacement. Download it only from the official site: protonvpn.com (not a third-party site). Create a free account with your email address. This gives you an independently audited, no-logs, open-source VPN with no bandwidth limit at zero cost.
- 5Test your VPN is actually working after installing it. With the VPN connected, visit dnsleaktest.com and run the Extended Test. All DNS servers shown should belong to ProtonVPN. Visit ipleak.net and verify the displayed IP is the VPN server's, not your real IP. If your real IP or ISP's DNS servers appear — the VPN is not protecting you.

❓ Frequently Asked Questions — Free VPN Privacy Risks 2026
What do free VPNs actually do with your data?
Most free VPNs monetise users' data to fund their server costs. Documented practices include: selling browsing history to data brokers and advertisers; embedding third-party tracking SDKs (from companies including ByteDance and Yandex, per Top10VPN investigation of 100 apps); injecting advertising cookies and tracking pixels into user browsers; selling user bandwidth to other companies (as Hola VPN did through Luminati); and leaking DNS requests that expose visited websites to ISPs despite the VPN being active. The landmark CSIRO/UC Berkeley/UNSW study of 283 Android VPN apps found 67% had third-party tracking libraries in their source code. A July 2026 study of 281 free Android VPN apps found 29 were leaking user traffic outside the VPN tunnel. Source: CSIRO study; The Hacker News July 2026 via technadu.com; TheBestVPN.com; Top10VPN.
Is it safe to use a free VPN?
For most popular free VPN apps, the honest answer is no — for privacy purposes. 65%+ of free VPN apps showed risky behavior (Zimperium research on 800 apps); 88% of top free Android VPNs leaked data in some form (Top10VPN); a July 2026 study found 4 free VPN apps running tunnels with zero encryption. However, a small number are genuinely safe — ProtonVPN free tier (Switzerland, no bandwidth limit, independent audit, open-source) and Windscribe (Canada, 10GB/month, transparent policy). These use the free tier as a funnel toward paid upgrades — they do not monetise user data. The critical question: how does this company make money? If the answer involves data or advertising partnerships, your privacy is at risk. Source: Zimperium; Top10VPN; The Hacker News July 2026; techjournal.org.
How do free VPNs make money if they don't charge users?
Free VPNs use several documented revenue models: (1) Selling browsing history and IP data to advertisers and data brokers — this is the most common and most damaging. (2) Displaying in-app advertisements targeting users based on their browsing data. (3) Selling user bandwidth — Hola VPN sold users' bandwidth through Luminati (now Bright Data), turning their devices into exit nodes for others' traffic. (4) Bundling malware or adware that collects device data. (5) Redirecting traffic through undisclosed affiliate networks for referral revenue — HotspotShield found by CSIRO to redirect traffic to Alibaba.com and eBay.com. (6) Premium subscription upsells — the only model that doesn't require monetising user data. Legitimate free VPNs (ProtonVPN, Windscribe) use only model 6. Source: TheBestVPN.com; CSIRO study; The Next Web on Hola/Luminati.
What was the SuperVPN data breach and what data was exposed?
Security researcher Jeremiah Fowler discovered a publicly accessible, password-free database containing 360,308,817 records (133 GB) from SuperVPN. Exposed data included: user email addresses, original IP addresses (the real ones the VPN was supposed to hide), geolocation records, unique user IDs, device models, OS information, VPN server connection records, and references to specific websites users had visited. SuperVPN's published policy claimed "no logs." The breach directly contradicted this. Both SuperVPN apps (100M combined downloads) were linked to Chinese companies. This was SuperVPN's fourth documented security incident (2016, 2020, 2022, 2023). Source: Jeremiah Fowler disclosure; CPO Magazine June 2023; VPNMentor; Fox News CyberGuy.
What did the CSIRO study find about free VPN apps?
The CSIRO/ICSI/UC Berkeley/UNSW academic study of 283 Android VPN apps found: 67% had third-party tracking libraries in their source code; 82% requested permissions to access sensitive Android device data (user accounts, text messages, system logs); 16% deployed non-transparent proxies, sometimes used to inject JavaScript for advertising/tracking; four apps used TLS interception (may allow inspection of encrypted browsing traffic); Betternet had the highest tracking library count (14 libraries); HotspotShield redirected traffic to Alibaba.com and eBay.com through affiliate networks. These findings established that the majority of free VPN apps had practices directly contradicting their marketed privacy benefits. Source: CSIRO/UC Berkeley/UNSW study, cited by bitlaunch.io March 2026.
What is Hola VPN and why is it considered dangerous?
Hola VPN is an Israeli free VPN service with 152M+ users that turned users' devices into exit nodes for other people's internet traffic through its sister company Luminati (now Bright Data). When you used Hola's free VPN, your device's bandwidth was sold to Luminati's paying customers, who used your IP address to conduct their own internet activity — including documented criminal activity like DDoS attacks. You bore the legal risk that activities traced to your IP address were not your own. Hola has since updated practices and implemented some fixes, but researchers note concerns persist. This model is sometimes called "peer-to-peer VPN" but fundamentally means you provide your internet connection to strangers for money while getting a free VPN in return. Source: The Next Web; multiple cybersecurity investigations.
Can a free VPN contain malware?
Yes. Kaspersky reported that malicious apps posing as free VPNs rose 2.5 times in Q3 2024 vs Q2 2024. Zimperium research found 65%+ of 800 free VPN apps on Apple/Google stores showed risky behavior including dangerous APIs. Top10VPN found similar failures across 100 apps. A 2026 review of 18 free Android VPNs found nearly all contained embedded trackers and many requested camera, microphone, contacts, and call logs access — behavior one report described as resembling spyware. The malware risk is highest with apps from unknown developers, no verifiable company information, and no cybersecurity community coverage. Source: Kaspersky Q3 2024; Zimperium; BGR May 2026; techjournal.org.
What are the signs of a free VPN that is actually safe to use?
Signs of a legitimately safe free VPN: (1) Free tier from a company primarily funded by paid subscriptions — not advertising or data. Examples: ProtonVPN and Windscribe. (2) Published independently audited no-logs policy from a named third-party security firm. (3) Open-source application code (publicly verifiable). (4) Based in a privacy-friendly jurisdiction (Switzerland, Iceland, Panama) outside 5/9/14-Eyes intelligence alliances. (5) Minimal app permissions — only VPN profile creation; no camera, microphone, contacts, or call logs. (6) Privacy policy explicitly states browsing history is not collected or shared. (7) Transparent, verifiable company with identifiable founders and public company registration. Source: techjournal.org; BGR May 2026; bitlaunch.io March 2026.
What does a no-logs policy actually mean for a VPN?
A no-logs policy means the VPN claims not to store records of your internet activity — websites visited, traffic content, original IP, or connection timestamps. In theory, if compelled by authorities, there is nothing to hand over. In practice, many free VPNs claiming no-logs have been proven to maintain logs. SuperVPN's breach (2023) exposed 360M records including visited websites — directly contradicting their no-logs claim. A VPN's no-logs policy is credible only when independently audited by a named third-party security firm with the audit report published. Self-certified "zero logs" claims are marketing, not evidence. The only reliable no-logs claims come from providers with published third-party audits or real legal test cases where they produced no user data. Source: CPO Magazine June 2023; bitlaunch.io March 2026.
Are there any free VPNs that are actually trustworthy in 2026?
Yes, but a small minority: (1) ProtonVPN Free — Switzerland (outside 5/9/14-Eyes); no bandwidth limit; independently audited no-logs; open-source; funded by paid subscriptions; speed is lower on free servers but privacy protections are identical to paid. Download only from protonvpn.com. (2) Windscribe — Canada; 10GB/month free; transparent privacy policy; independently audited; subscription-funded. These are genuinely different because their business model requires no data monetisation — the free tier converts users to paid plans.

Can Nigerians and Africans legally use VPNs?
In Nigeria, VPN use is not currently prohibited by law. No Nigerian legislation specifically bans individual VPN usage. Nigerians legitimately use VPNs for privacy, geo-restricted content, and public Wi-Fi security. The Nigerian Communications Commission (NCC) has engaged in selective internet disruptions historically, and future regulatory changes cannot be ruled out. Across Africa, VPN legal status varies — Egypt, Uganda, and Ethiopia have restricted VPN use. The legal risk specific to VPNs in Nigeria is not from using them but from what you do while using them (illegal activity remains illegal). An additional practical risk: if you use a free VPN with DNS leaks (confirmed in 24 apps with 360M installs in July 2026 research), your ISP can still see your visited websites despite the VPN being active. Source: NCC Nigeria; The Hacker News July 2026 via technadu.com.
What is DNS leaking and why does it matter for free VPNs?
A DNS leak occurs when DNS queries — your device's requests to translate website names into IP addresses — are sent outside the VPN tunnel to your regular ISP rather than through the VPN server. This means your ISP sees exactly which websites you are visiting despite the VPN being active, completely defeating the privacy purpose. A July 2026 study of 281 free Android VPN apps found 24 apps specifically leaked DNS requests, exposing visited websites to local network operators. Those apps alone account for approximately 360 million installs. For Nigerian users on MTN, Airtel, Glo, or 9mobile: DNS leaks mean your mobile network operator can see your browsing activity. Test for DNS leaks at dnsleaktest.com with your VPN active — all DNS servers shown should belong to the VPN provider, not your ISP. Source: The Hacker News July 2026 via technadu.com; Top10VPN (88% leakage finding).
How can I check if my VPN is actually working and protecting my data?
Four tests to verify your VPN is working: (1) IP address check — visit ipleak.net with VPN connected. The displayed IP should be the VPN server's, not your real ISP-assigned IP. (2) DNS leak test — visit dnsleaktest.com and run Extended Test. All DNS servers shown should belong to the VPN provider, not your ISP. Any ISP DNS server = DNS leak. (3) WebRTC leak test — visit browserleaks.com/webrtc. WebRTC can expose your real IP through browsers even with an active VPN. If you see your real IP, disable WebRTC in browser settings. (4) Kill switch test — suddenly disconnect the VPN and check if your internet cuts off immediately. A working kill switch prevents IP exposure during VPN drops. Many free VPNs lack kill switches. Run these tests after any VPN installation before using it for sensitive browsing. Source: techjournal.org; bitlaunch.io March 2026.
What data does a VPN actually hide from your ISP?
A properly functioning VPN hides from your ISP: the content of your internet traffic; the specific websites you visit (your ISP sees only the VPN server's IP); the specific resources you access within a session. What a VPN does NOT hide from your ISP: the fact that you are using a VPN (your ISP always sees you connected to a VPN server); your connection times and data volume; your real IP address (your ISP always knows this — VPN hides it from websites, not from your ISP). What a VPN does NOT protect against regardless of quality: tracking by logged-in services (Google knows you at Gmail); browser fingerprinting; cookies; malware in downloaded files; phishing. A VPN is one privacy layer, not a complete security solution. For free VPNs with DNS leaks: even these basic ISP protections are broken. Source: techjournal.org; Google guidance; multiple security publications.
What should Nigerians specifically look for before installing any VPN app?
Before installing any VPN in Nigeria: (1) Company jurisdiction — Switzerland, Iceland, Panama are strong. Unknown or China-linked companies are high risk. (2) Privacy policy — search for "data we collect" and "how we share data." Any mention of "marketing partners" or "advertising companies" is a red flag. (3) Permissions requested — check before granting. A VPN needs only VPN profile permission. Camera, microphone, contacts, call logs = red flag. (4) Developer identity — no website, no address, no verifiable company = delete immediately. (5) Independent coverage — search the VPN name + "security research" or "data breach." (6) Check Top10VPN.com for investigated free VPNs. (7) If no independent coverage exists and the VPN is completely free: start with ProtonVPN free instead — the alternative is always the trusted option when a free VPN's practices cannot be verified.
