Pitak is a privacy-first, offline personal library catalogue. Catalogue your books, lend them to borrowers from an encrypted vault, keep a wishlist, import/export your data, make portable backups, and optionally publish a read-only library site.Features:
* Library — add, edit, search, sort and filter books; soft-delete with restore; on-device cover capture; ISBN barcode scan with metadata lookup (Open Library → Google Books, chained and cached).
* Borrowers vault — a persistent, AES-256-GCM encrypted store for borrowers and loans, unlocked by a passphrase (Argon2id key derivation). Optional biometric unlock.
* Wishlist — track books to acquire; move them to the library on purchase.
* Import / Export — JSON, CSV (including Goodreads import), and paginated PDF export with Indic-script support.
* Backup / Restore — portable .pitabak archives.
* Publish — optionally push a read-only library viewer to GitHub Pages, with PII redaction.
* App-lock — optional biometric/device-credential gate before the library screen.
Privacy posture: local-first by default. Sensitive data lives in the platform Keystore; secrets are held as wipeable bytes. Network calls happen only on explicit user action (ISBN lookup, publish, opt-in remote covers). Screenshots are blocked while sensitive data is visible.
The cryptographic core is written in Rust and built entirely from source.
WhatsNew:
* Security update: photos used for book covers and event posters no longer keep their embedded metadata (including GPS location) when published; merging library files is now safer (duplicate entries are surfaced instead of silently failing, and catalogue replacement can no longer leave a partial library); CSV exports are protected against spreadsheet formula injection; various privacy hardening.
Anti-Features: NonFreeNet(this application promotes/depends a non-Free network service):
⇒ ISBN lookup relies on openlibrary.org and publish function relies on GitHub.
While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device.
