Install the APK

CallVault ships as a signed Android APK, not through Google Play. (Play policy bans silent call recorders — see What is CallVault.) You install it directly and update it the same way.

Requirements

• An Android phone on Android 8.0 (API 26) or newer.
• Room to sideload an app from outside the Play Store.
• Optional, for both-sides recording: a rooted device running BCR — see Recording.

Install

1. Open the GitHub Releases page and pick the latest release.
2. Download the APK attached to that release — the universal app-release.apk works on any device; the per-ABI APKs are smaller if you know your CPU architecture.
3. Open the downloaded file. Android will ask you to allow installing from this source — grant it for your browser or files app, then confirm the install.
4. Launch CallVault and follow the first-run onboarding.

Updating

There is no in-app auto-update — that would need a backend and would undercut the no-telemetry stance. You pull updates yourself:

1. Download the newer APK from a later GitHub Release.
2. Install it over the top of the existing app.

Because every release is signed with the same key, installing over the top preserves your data. Installing an APK signed with a different key would force an uninstall and lose local recordings, so only ever update from the official releases.

:::tip Keep the universal APK If you are unsure which ABI your phone uses, always grab the universal app-release.apk — it installs anywhere. :::
