+## Update And Release Policy
+
+The Android app cannot silently replace itself. It may download a newer APK and
+open Android's package installer, but the user must approve the install. On
+Android 8+, the user may also need to allow this app to install unknown apps.
+
+The app checks exactly one update source per run: the selected manifest/API URL.
+GitHub is the default public source. Gitea is available as a public mirror, but
+the app does not fall back across both providers during a normal check. This
+keeps update behavior predictable on mobile networks and avoids duplicate
+provider checks.
+
+Downloaded APKs are cached by `versionCode`. If a cached APK exists and its
+SHA-256 matches the manifest, the app reuses it instead of downloading the same
+version again. This matters when Android redirects the user to unknown-app
+install settings before the installer can run. After the user grants that
+permission and returns to the app, the app resumes installation of the pending
+APK instead of asking the user to run update again.
+
+Only `v*` tags publish GitHub Releases. Main branch builds and manual workflow
+runs are for CI artifacts and should be used to validate grouped changes. Do not
+publish a new tag for every small UI copy or layout change; publish when there
+is a useful feature or test batch for phone-side validation.
