Description
Watch your cold-storage balance without a seed phrase on your phone. Paste a zpub, an output descriptor, or the two lines of Bitkey's wallet export, and Bag tracks the balance over Tor - your keys never leave the device. Add manually entered balances for coins held elsewhere, see your net worth in up to 3 currencies, log your DCA buys and keep a live widget on your home screen.
Bitcoin-only. No altcoins. No ads. No accounts. No analytics. Your holdings never leave your device.

PRIVACY & SECURITY
Only derived addresses ever reach the block explorer - your xpub, descriptor and balance stay on-device, encrypted at rest. Every network path can be routed through Tor (Orbot required) and fails closed if Tor is down. No phone-home, no telemetry, no third-party SDKs. Optional biometric lock.
