Free VPN Risks: Are Free VPNs Safe to Use in 2026?

The biggest free VPN risks are not obvious from an App Store listing. Many free apps quietly log your traffic, inject ads, or bundle trackers, and some have leaked or sold user data. Running a VPN costs money, so a free-only app recoups that cost somewhere.

#What Are the Real Risks of Free VPNs?

A VPN routes all your internet traffic through its servers, so the provider can see everything a snoop on the same network would want to see. That is acceptable when you trust the company and it has a reason to behave. With a free app that has no clear owner and no paid product, the incentives flip. The first question is whether you need a VPN at all, and the second is whether the free one you grabbed is trustworthy.

Logging and data resale top the list. A VPN can record the sites you visit, your real IP address, and connection timestamps, then bundle that into a profile and sell it to advertisers or brokers. That is the same data-broker economy people try to escape when they remove data from broker sites.

Then there is tracking and ad injection. A 2016 study of 283 Android VPN apps found that roughly 75% embedded at least one third-party tracking library and 38% showed signs of malware, and some apps slip their own ads into the pages you load.

Malware is the scariest risk, and that is why questions about whether iPhones need antivirus keep surfacing.

The fourth risk is the strangest. Some free VPNs sell your spare bandwidth, turning your device into an exit node that strangers route their traffic through. Someone else’s activity can then look like it came from your home connection.

#The Three Tiers of Free VPNs

Not all free VPNs are equally risky. It helps to sort them into three tiers, from the safe end to the one you should avoid.

The first tier is the free trial of a paid VPN. NordVPN, ExpressVPN, and others let you use the full paid product for a week or a month, sometimes through a money-back guarantee. The company wants you to subscribe, so it has no reason to mistreat your data. This is the lowest-risk way to use a VPN for free.

The second tier is a limited free plan from a company that also sells paid subscriptions. Proton VPN Free and Windscribe Free fit here, capping speed or servers to nudge you toward upgrading.

Most dangerous is the third tier: the standalone “unlimited, 100% free” app with no paid product and often unclear ownership. This is where the documented harm lives. According to Mozilla’s privacy team, a free VPN without a legitimate business model is unlikely to invest in real privacy protection and may sell your data to stay afloat.

We tested a batch of these “free forever” apps in 2026, and the ones with no paid tier were the most aggressive, loading extra ad SDKs and asking for permissions a VPN has no business needing.

Free VPN apps and tiers sorted by privacy risk, from safest to most dangerous

VPN or tier	Type	How it makes money	Risk level
NordVPN or ExpressVPN trial	Free trial of paid plan	Subscription afterward	Low
Proton VPN Free	Reputable free tier	Sells paid plans	Low
Windscribe Free	Reputable free tier	Sells paid plans	Low to medium
Hotspot Shield (free)	Ad-supported	Ads and data sharing	Medium to high
SuperVPN and many "100% free" apps	Standalone free	Unclear or hidden	High
Hola VPN (free)	Peer-to-peer	Resells your bandwidth	High

#Free VPNs That Have Actually Harmed Users

Take Hola VPN. Researchers in 2015 found that it was reselling users’ idle bandwidth through a sister company, turning millions of devices into a botnet that attacked other sites.

In 2017, a complaint filed with the FTC by the Center for Democracy and Technology alleged that Hotspot Shield shared data with advertisers, used more than five tracking libraries, and redirected some e-commerce traffic. The complaint was an allegation, not a court ruling, but it described exactly the pattern privacy researchers warn about.

The clearest case is more recent. In 2023, security researchers found an unsecured SuperVPN database sitting open online. CPO Magazine reported that the leak exposed more than 360 million records, around 133GB, including IP addresses and the sites users visited, which flatly contradicted the app’s no-logs claim.

#Is Proton VPN’s Free Tier Actually Safe?

Proton VPN Free is the rare free VPN we would actually install. It comes from Proton, the Swiss company behind Proton Mail, and it has no data cap.

In our testing across iOS and Android in 2026, the free tiers from established paid providers like Proton and Windscribe connected cleanly, with no bundled trackers and no permission requests beyond the VPN profile itself. The free apps with no paid tier were the opposite, asking for contacts or location access a VPN has no reason to need.

The tradeoffs are real. The free plan limits you to servers in a handful of countries and gives you slower speeds than paying customers get. For a fuller look at paid options, see our guide to the best VPNs for iPhone, and if your connection drops or refuses to start, our fix for a VPN not connecting on iPhone covers the usual causes.

#Free VPNs on iPhone vs Android

The platform matters. Most documented malware research, including that 283-app study, focused on Android, where sideloading and broad permissions give a bad app far more room to misbehave.

On the iPhone, the picture is better but not clean. According to Apple’s Network Extension framework documentation, iOS VPN apps run inside a sandbox and connect through a managed system profile, which limits how much a rogue app can touch. App Store review also screens out many of the worst offenders.

That does not make a sketchy free VPN safe on iOS. A logging or data-selling app behaves the same on either platform, because your data still flows through its servers regardless of the sandbox. If you are new to this, our explainer on what a VPN does on iPhone covers the basics.

#How to Choose a Safe Free VPN

So how do you actually pick one? Three quick checks separate a safe free VPN from a dangerous one.

Start with the business model. A VPN that also sells a paid plan treats its free tier as a sample, so it has a reason to protect you rather than profit off your data. That is the single strongest signal.

Check the permissions next. A VPN needs the network profile and nothing else, so a free app begging for contacts or location access is waving a red flag.

Look for proof, not promises. A no-logs claim means little by itself, so favor providers that publish independent audits and have a paid business to protect. Proton and Windscribe both clear that bar; an anonymous app with no audit and no name behind it does not.

#Bottom Line

If you only need a VPN occasionally, lean on the free tier of a company that also sells a paid plan. Proton VPN Free is the safest pick, and Windscribe Free is a solid backup.

Stay away from any “unlimited, 100% free” app with vague ownership and no paid product, because it has to earn its money from you somehow. If you want a VPN running on all your devices around the clock, a reputable paid plan like NordVPN at roughly $3 to $5 a month removes the whole question of how the free one survives.
