Back up your budget

Sign in with your email so you never lose your data. Restore everything on a new phone in seconds — fully encrypted.

🔒 Your password never leaves your device. Your data is encrypted with a key derived from it (PBKDF2 + AES-GCM) before backup. Offline use works without an account.

Private by default. Everything you enter is stored on your device and works fully offline — no account required.

Encrypted backup. When you sign in, a key is derived from your password (PBKDF2, 150k iterations) and used to encrypt your data with AES-GCM before it's backed up. Your password and plain data never leave your device — even the backup can't be read without your password.

Cross-device recovery. Sign in on a new phone with the same email and password to restore everything from your encrypted backup. You can also download a .bcvault backup file and keep it anywhere safe.

Fast entry. The keypad is a real calculator — type 12+3.50 and it adds up before saving. Pick a category chip and tap SAVE.

Plan ahead. The Budget tab splits your income with 50/30/20 (and other rules) and compares it to what you've actually spent this month.
