Two ways to get the same app. Version 1.0.0, for Android 8.0 or newer.

The easiest way. Google checks the app, installs it in one tap and keeps it updated by itself.

APK (direct download)

For phones without Google Play, or if you prefer to install it yourself. It is the same app, signed with the same key, and it can update itself safely.

Install the APK safely

  1. Download the APK from this page only (cybersecprotocol.app). Never from a copy sent in a chat or posted elsewhere.
  2. Check its fingerprint (below). If it is different, delete the file: it is not ours.
  3. Open it. Android asks to allow your browser or file app to install apps: allow it for this once.
  4. After installing, go back to Settings > Apps > Special access > Install unknown apps and switch that permission off again.

Updates: the app checks this website for a newer version and installs it only if the file has the right fingerprint, the same package name and the same signing key. Android always asks you before installing.
