Free VPNs That Don't Sell Your Data in 2026: 2 I Actually Trust

Why do "free" VPNs sell your data?

Running a VPN costs real money — servers, bandwidth, staff. A free VPN has to pay for that somehow, and for most of them the answer is you. Audits of the free VPN market keep finding the same pattern:

• 80%+ of free VPN apps contain tracking code of some kind, and around 38% contain malware, according to industry audits that keep being cited through 2026.
• Hola VPN (150+ million downloads) was caught selling users' bandwidth and browsing data — it turned devices into exit nodes for strangers.
• Facebook's Onavo was a free VPN that fed traffic data back to Facebook, which used it to spot competing apps early.
• Browsing profiles get packaged and sold to data brokers for roughly $0.001–0.01 per user per month — pennies per person, but huge at scale.

The only free VPNs that consistently pass privacy checks are freemium services: a genuinely free tier funded by people who pay for the full product. That's the whole secret. If a free VPN can't show you a paid product and a clear business model, assume your data is the product.

Proton VPN Free: the only unlimited option

Proton VPN Free is the only free VPN I've seen that's genuinely unlimited — no data cap, no speed cap, no time limit. Proton's own page says it plainly: the free plan has no data or speed limits, no ads, and doesn't log your activity, and it's "free forever." A few specifics that matter:

• Unlimited data and bandwidth — all Proton servers deliver at least 1 Gbps, including free ones.
• Strict no-logs policy, and the apps are open source and independently audited.
• Swiss jurisdiction — Proton is based in Switzerland, which has strong privacy laws.
• Free is funded by paying users, not ads or data sales. That's the model that makes it trustworthy.

The tradeoffs are real: you get one device on the free plan, a small set of free server locations (US, Netherlands, Japan and a few others), and no streaming/P2P support — those are paid features. If you need more than one device or specific countries, our Proton free vs paid comparison walks through exactly what you get for the upgrade.

Windscribe Free: 10GB that actually resets

Windscribe is the other free VPN I'd actually install. Its free plan gives you 10GB of data per month after email confirmation (2GB without), access to servers in 10 countries, and — unusually — unlimited simultaneous devices. The privacy credentials hold up:

• No-logs policy audited by Packetlabs (2024 audit), and the apps are open source.
• R.O.B.E.R.T. — a built-in ad, tracker and malware blocker, included free.
• Canadian jurisdiction, and the free tier is again funded by paid subscribers, not data sales.

The catch is the cap: 10GB is roughly a few hours of HD streaming, so it's best for regular browsing, light streaming and the occasional download — not as your always-on daily driver. If you're weighing it against the 10GB tier's limits, our Windscribe free 10GB deep dive shows what the cap actually feels like in practice.

Proton vs Windscribe: side by side

How to spot a free VPN that sells your data

You don't need to be a security researcher to avoid the bad ones. Five checks catch almost everything:

• Can it explain how it makes money? If the page is vague about monetization, the data is probably the product.
• Is there a real paid plan? Freemium models (free tier + paid product) are the only free-VPN model that reliably funds itself without your data.
• Does it publish a clear privacy policy? Look for "no logs" stated in plain language — and ideally an independent audit backing it.
• Is the app open source? Not a guarantee, but open-source code means independent eyes can check what it actually does.
• What do the store listings say? Apps with heavy ad SDKs or sketchy permissions get flagged in reviews and audits over and over.

Bottom line

Free VPNs that don't sell your data exist, but the list is short on purpose. Proton VPN Free is the pick if you want unlimited data with zero caveats; Windscribe Free is the pick if you want 10GB across unlimited devices with built-in ad blocking. Everything else I've seen either tracks you, injects ads, or hides behind a privacy policy that says "we may share data with partners" — which is data selling with extra steps. Skip those, install one of these two, and you're actually getting the free part.
