Download Zuno for Android
Zuno as a file you install yourself, without an app store. It doesn't update on its own: new versions are published on this page.
Released . . For Android 7 or newer on a 64-bit device. Some older and low-cost devices are 32-bit, and Zuno doesn't run on them.
The latest version couldn't be loaded. Reload the page to try again.
Install
- Open the downloaded file.
- Android asks whether your browser may install apps. Allow it, then choose Install.
- That permission can be turned off again afterwards, in Android's settings. Zuno doesn't need it.
Updates
When a new version is published here, download it and open it. It installs over the old one, and your chats stay as they are.
Don't uninstall Zuno to update it. Uninstalling removes this device's encryption keys, and reading older messages again then takes your recovery code or another signed-in device.
Check the download
Both checks are optional, and both run on a computer.
- File checksum (SHA-256)
- Run
sha256sumand compare the result, or use the checksum file withsha256sum -c. A match means the file arrived complete and is the one published here. The checksum comes from the same place as the file, so it can't prove more than that. - Signing certificate (SHA-256)
3e8ebb143df08e90fe489ebd74915a9692df1a5264cedf2001b52ba738585999- Run
apksigner verify --print-certs. Every version published here is signed with this certificate, so this is the stronger check: a file signed by anyone else shows a different value. - What Android checks on its own
- Once Zuno is installed, Android refuses any update that isn't signed with the same certificate. That holds whether or not you run the checks above.
