Install the Android app

The Android app is built from source and installed as a debug APK. It targets arm64 devices. There is no store listing yet.

Build it

You need Rust with the aarch64-linux-android target, the Android SDK and NDK, Node 24 and pnpm.

git clone https://github.com/rustiqz/Vaultiq.git
cd Vaultiq/mobile
pnpm install
pnpm run crypto                 # cross-compile the core, generate Kotlin bindings
cd android && ./gradlew assembleDebug

The APK is in app/build/outputs/apk/debug/. Install it with adb install or copy it to the phone.

First run

Choose one of the options on the first screen:

  • Create a vault on a server you run (needs an invitation token).
  • Join an existing vault by scanning a QR code from the extension’s Add a device, or by pasting a token.
  • Use without a server for a local-only vault.
  • Restore from an exported backup. A restored vault is always local-only.

Turn on Android autofill

Vaultiq fills logins in other apps through Android’s autofill service. Switch it on in system settings: Settings → Passwords & accounts → Autofill service (the wording varies by device), then choose Vaultiq. See Autofill and saving logins.

Fingerprint unlock

After you unlock with the master password once, enable fingerprint unlock in Settings. See Unlocking and locking for how it works and what invalidates it.
