Is a free VPN safe to use?
Some free VPNs are safe; many are not. Whether a free VPN is safe comes down to one question — who runs it, and can you verify their claims — not to the price. Here is how to tell the difference, with the evidence, dated and sourced.
Whether a free VPN is safe depends almost entirely on who is behind it. The free tiers run by named, audited providers — Proton VPN and Windscribe among them — are safe to use. A large share of the anonymous "free VPN" apps in the app stores are not, because a service that costs real money to run and charges you nothing has to make its money some other way. The good news is that the difference is easy to check once you know what to look for, and the safe free VPNs are a short, knowable list.
What a VPN can and cannot protect
A VPN encrypts the traffic between your device and the VPN server and hides your IP address from the websites you visit — useful on public Wi-Fi and against your internet provider's snooping. What it does not do is make you anonymous. It moves your trust to the VPN provider, who now sits where your ISP used to and can see what a passive network could. Anyone promising "total anonymity" or an "untraceable" connection is overselling. This is exactly why the identity and honesty of a free provider matter more than any feature list: you are choosing who gets to see your traffic, not removing the watcher.
The three ways a free VPN can hurt you
There are three concrete risks, and they are all documented. The first is data monetisation: a free app that logs and sells your browsing activity, or injects ads and trackers into your traffic. The second is malware and tracking code bundled into the app itself. A study of 283 Android VPN apps (Ikram et al., 2016 Internet Measurement Conference, by CSIRO/Data61, UNSW and UC Berkeley) found 38% contained malware or malvertising and two-thirds embedded third-party trackers. The third is plain incompetence — weak or absent encryption and traffic leaks; the same study found roughly one in five apps did not encrypt traffic at all. We break the money side down in how free VPNs make money.
These are not old problems. In 2023, a researcher found an exposed database of about 360 million records tied to the free app SuperVPN, including email addresses and records of visited sites (CPO Magazine, 2023). And an April 2025 report by the Technology Transparency Project found one in five of the top 100 free VPNs on the US App Store were quietly owned by Chinese companies — a question of ownership transparency we look at separately.
What makes a free VPN safe
A safe free VPN has four things a dangerous one lacks. It has a named company with a findable jurisdiction, so someone is accountable. It has an honest business model — usually freemium, where the free tier is a funnel to a paid plan, so the incentive is to convert you rather than harvest you. It has an independent audit of its no-logs claim or its infrastructure, dated and published. And it asks only for the permissions a VPN needs — the network connection, nothing about your contacts, messages or precise location. Proton VPN, for example, funds its free plan from paid subscriptions and has passed consecutive independent no-logs audits (Securitum, 2024–2025); that is what "safe" looks like in practice.
So which free VPNs are safe?
The free tiers we consider safe are Proton VPN Free (unlimited data, no ads, audited no-logs), Windscribe Free (10GB a month, independent, no affiliate programme), PrivadoVPN Free (10GB, best for the occasional stream but no published audit), and — with narrower use cases — hide.me and TunnelBear. The full ranking, with data caps and caveats for each, is our best free VPN guide.
How to check any free VPN in two minutes
Before you install any free VPN, ask seven quick questions: can you find the owner and its country; is there a published audit; is it the free tier of a paid provider; is it marketed as unlimited-and-free by a brand you have never heard of; does it want permissions unrelated to networking; does it show ads or bundle software; and is its privacy policy specific about what it collects. Our free VPN safety checklist turns those into a two-minute score, and the red flags guide explains why each one matters. If you cannot find out who owns a free VPN, treat that as a no.
