Installation help

Android 11+

1. Download the APK to a phone running Android 11 or later.
2. Open the downloaded file. If Android asks you to allow installation from your browser, enable it in settings and return to the installer.
3. Sign in by email and tap “Start 7 days free”. One trial per verified email across all devices. No card and no automatic conversion to a paid plan. Scan the TOTP setup QR from your service. Create a manual backup or enable cloud backups with a separate password.

For updates, install over the previous version. Do not uninstall the app: uninstalling without a backup can cause loss of keys.
