Proton VPN for Android is one of the very few free VPNs worth installing without a second thought.
Built by the Swiss team behind Proton Mail, it pairs a strict no-logs policy with something almost no competitor offers on a free plan: unlimited data.
Most "free" VPNs throttle your speed, cap you at a few hundred megabytes a day, or quietly sell your browsing history to pay the bills.
Proton takes a different route - the free tier exists to fund the paid one, which is exactly why the free version is usable rather than a crippled trial.
This page breaks down what you actually get for nothing, where the paid plan starts to matter, and how it stacks up against the other privacy tools worth keeping on your phone.
What Proton VPN Actually Does - in Plain Terms
A VPN routes your phone's internet traffic through an encrypted tunnel to a server somewhere else, hiding your real IP address from the websites you visit and shielding your activity from your mobile carrier or whoever runs the Wi-Fi you're on.
Proton VPN does this with modern WireGuard and Stealth protocols, which connect fast and drain less battery than older standards.
Earlier in 2026 Proton dropped OpenVPN entirely, routing every connection through these faster, leaner protocols.
For the average person, the practical result is simple: public Wi-Fi at a cafe or airport stops being a risk, and the sites you browse can't pin your location to your actual address.
Free vs Paid - What the Free Plan Really Gives You
This is where Proton separates itself from the pack. The free plan includes unlimited data with no daily caps, access to servers in a handful of countries, and the same audited no-logs privacy as the paid tier.
The trade-off is that you don't choose your server location - the app picks the fastest free one for you - and you connect a single device at a time.
The paid Proton VPN Plus plan unlocks servers in dozens of countries, lets you pick exactly where you appear to be (useful for streaming region-locked libraries), connects up to ten devices, and adds extras like the NetShield ad and tracker blocker plus Secure Core routing.
For most people who just want privacy on public networks, the free plan is genuinely enough; the paid plan earns its price only if you stream a lot of geo-locked content or want one subscription covering every device in the house.
Who Proton VPN Is For - and Who Should Look Elsewhere
Proton VPN is the right pick if privacy is your main reason for using a VPN.
Switzerland's strong data-protection laws, the company's open-source apps, and its independent security audits make it one of the most trustworthy names in the category.
It's also ideal if you've been burned by sketchy free VPNs - the ones that demand permissions far beyond what a VPN needs and leak your data in the background.
If your priority is unblocking a specific streaming catalogue or torrenting at high speed, the free plan's limited server choice will frustrate you, and you'd be better served stepping up to a paid plan or pairing it with a dedicated download tool.
Browser-based privacy is a separate layer worth adding too: a hardened browser like Tor Browser or Brave Browser handles tracker blocking and fingerprinting that a VPN alone can't, and our rundown of who's spying and who's protecting you explains where each tool fits.
How It Compares to Other Privacy Options
A VPN protects the connection; it doesn't protect the browser. The two work best stacked. If you want a built-in VPN inside the browser itself for light use, Opera Browser bundles a free proxy alongside its ad blocker, though it's no substitute for a full VPN like Proton on untrusted networks.
On the desktop side, Mozilla Firefox pairs naturally with Proton VPN for end-to-end privacy across all your devices, and the full lineup of privacy-first options lives on our web browsers page.
If you ever want to see what your apps are actually sending over that tunnel, the network analyzer Wireshark and the rest of our security tools sit alongside Proton as the deeper end of the same toolkit.
Proton's edge over browser proxies is that it covers every app on your phone, not just the one tab you're looking at - your media apps, your messaging, your downloads, all tunneled at once.
Installing the APK Safely
Sideloading an APK is straightforward, but it's worth doing carefully given how many fake VPN apps circulate.
Download the file, allow installation from your browser or file manager when Android prompts you, and open the app to sign in or create a free Proton account.
If you want to confirm the package is clean before installing, run it through our APK Checker first - it inspects the file's permissions and signature so you know exactly what you're installing.
Once Proton is running, the rest of your media setup slots in around it: Android players like VLC for Android and MX Player handle your video playback, the Blackmagic Camera app handles capture, and CapCut for Android handles editing, all with Proton running the privacy underneath.
Get Proton VPN 5.18.75.1 Free for Android
The current build is version 5.18.75.1, weighing in at about 53MB. The download on this page is the free, virus-free APK - the same app, with the paid features simply unlocked by signing into a Plus account if you ever choose to upgrade.
There's no trial clock and no data cap on the free tier, so you can install it, use it indefinitely, and decide later whether the paid plan is worth it for you.
If you want broader playback support to go with it, the VLC for Android player and the MX Player Custom Codec add-on round out a private, format-complete phone setup, and you can browse everything else in the Android APK section.
