Privacy is not a feature. It's the foundation.

Your financial data is deeply personal. GrossBuh was built from the ground up to keep it yours.

No Account Required

Open the app and start tracking immediately. No email, no password, no profile.

Your Data, Your Keys

All transactions are stored in an encrypted SQLite database on your device. Zero telemetry. When you sync, data is protected by end-to-end encryption — your private key never leaves your device.

Open Source Technology

Built on open standards — SQLCipher, OPFS, and Web APIs. Inspect, audit, and trust the stack.

Device sync optionally transmits your data over the network — but it is always encrypted end-to-end using your personal public/private key pair generated on your device. No server ever sees your unencrypted data, and your private key is never transmitted.
