Backup & restore

Three independent paths to get the book in or out of this device. Cloud sync (auto-push to Google Drive or Dropbox) lives on its own screen — the Books page — and is separate from everything here.

Book file

Hands the encrypted DB blob to the system share sheet / file picker. Use it when you want a portable copy of the book in your own cloud storage (iCloud Drive, Files, Dropbox, etc. — whatever the OS picker offers), or to move a book between devices without using a sync provider.

• Save book file… — exports the current book as .db

(native) or .amdb (web, with AMDB magic + length-prefixed salt / iv / ciphertext). The system share sheet decides where the bytes land.

• Open book file… — picks a .db / .amdb and lands it as

a NEW book alongside the active one (collision-suffixed with the date). Prompts to switch when done; the current book stays untouched.

Encrypted books keep their password; restoring on another device asks for the same password before the data is readable. Lose the password and the file is unreadable — there's no recovery.

Backup (JSON)

Serialises the entire book — every account, transaction, recurring template, report, and setting — to a single JSON snapshot. Plain text, human-readable, round-trips losslessly back into a new book. The textarea below the button shows the JSON; copy it or hand it to the system share sheet / browser download.

Use it for: archival, transferring to another tool, or as a sanity check that everything serialises correctly. NOT encrypted — if the book has a password, this is the only path that exposes the plaintext.

Restore from JSON

Paste a previously-saved snapshot or pick a file. The Validate step parses it and shows a row-count preview (accounts, categories, transactions, …) with a before / after delta against the current book. Restore this snapshot overwrites EVERYTHING in the current book — use "Back up current data first" right above it if you might want the current state back.

Schema-version mismatches and translation notes surface inline so you know what to expect from a legacy 2014-era backup.

Reset / delete

The full "wipe this book" surface lives in More → Reset book or Books → trash icon. Use a fresh backup first if you might want any of this data later.
