Private beta · v0.10.3-beta

Android beta

A sideloaded build for testers — Zitrone is not in any app store yet. It connects to the relay.sublemonable.com server and pins that server's certificate — so this build only talks to that relay.

This is a pre-release.

  • Expect bugs, breaking changes, and data resets between builds.
  • Not distributed through Google Play — you install it manually (sideload).
  • It is unaffiliated with the Play Store and receives no automatic updates.

Want stronger anonymity? Use the Tor mirror.

Downloading over clearnet reveals your IP address to anyone monitoring connections to zitrone.app. The Tor onion mirror serves the same APK — same binary, same checksum — without exposing your IP. Open the address below in Tor Browser to reach the mirror page and download the APK:

The APK served there is identical to the direct download — verify with the same checksum below regardless of which path you use.

SHA-256 checksum

Installing

  1. Download the .apk to your Android device (or transfer it over).
  2. Open it. Android will ask to allow installs from your browser or file manager — grant Install unknown apps for that app (Settings → Apps → Special access → Install unknown apps).
  3. Confirm the install. Play Protect may warn you because the app is sideloaded.
  4. To update, download a newer .apk and install over the top — verify its checksum each time.

Want to test the Play Store beta?

The sideloaded APK above is great for kicking the tires — but it doesn't count as qualified beta testing. For the production release, Google requires testers who install the beta through Google Play itself (which means a Google account on the test device). If you're up for that, sign up below and you'll be notified the moment the Play Store beta is available.

What qualified testing means

  • Install the beta from Google Play when it goes live.
  • Keep it installed on your phone for at least 21 days — continuous install time is what qualifies the test, not a quick look.
  • Report improvements or issues while you test — on GitHub Issues or by replying to the notification email.

Straight talk about this form, because Zitrone never asks for an email in the app: your address is forwarded as a single email to admin@zitrone.app and stored in no database — the maintainer's inbox is the entire list. It's used only to tell you when the Play beta is live, and a reply saying "remove me" is all it takes to be off it.

Found a bug?

File it on GitHub Issues. For anything security-sensitive, do not open a public issue — follow the responsible disclosure process instead. Never include message content or screenshots that reveal it.
