Your library, exactly where you need it.
Bonketiba's Backup & Sync system moves your offline Reading-Mode library between devices without giving up privacy or bandwidth. Everything is end-to-end encrypted, resumable, integrity-checked, and — when you're on the road — Wi-Fi aware. Distribution runs through navigator.bonketiba.com, the same CDN that serves the Bonketiba Browser installers.
Resumable sync
If a "Sync library now" run is interrupted — tab closed, laptop asleep, network drop — Bonketiba remembers which URLs already finished and offers to continue from the next unfinished one when you return. Nothing gets re-uploaded twice.
End-to-end integrity
Every encrypted bundle carries a SHA-256 checksum over its ciphertext, plus a canonical checksum over the pages it contains. Import fails safely with a clear message if the file has been truncated, tampered with, or corrupted in transit.
Wi-Fi aware background sync
Opt in to background sync and Bonketiba only refreshes your library on Wi-Fi or unmetered ethernet, above 20% battery, and inside your autosave window. Your bandwidth cap and last-synced timestamp are honored exactly like a manual run.
Short share links & QR
Move your library to a phone or a friend's laptop with a one-shot link or QR code valid for as little as five minutes. Tokens can be single-use, expire on their own, and can be revoked at any time — the passphrase never leaves your device.
Passphrase-encrypted bundles
Bundles are encrypted client-side with AES-256-GCM, derived from your passphrase using 200 000 rounds of PBKDF2-SHA256. The server only ever sees the ciphertext; without your passphrase, no one — including Bonketiba — can read it.
Downloadable conflict report
After every import you can download a CSV audit trail listing every URL, the strategy chosen, whether the incoming version was merged, replaced, or skipped, and the exact version numbers involved. Perfect for teams that need a paper trail.
How a round-trip works
- On Device A, click Export snapshot in the Sync panel. Optionally pick incremental (only pages changed since your last export) and add a passphrase — the file is encrypted before it ever leaves your device.
- Move the file however you like: download & email, drop into a shared folder, or generate a short link / QR and open it on Device B. Links can be single-use and time-boxed.
- On Device B, drop the file into the Sync panel. Bonketiba verifies the checksum, migrates the schema if needed, and shows a per-URL conflict preview with a per-item override.
- Confirm the import. Download the CSV audit report for your records; interrupted uploads resume from the last successful item.
The Sync panel lives inside your Bonketiba account. Sign in first, then open Library → Sync between devices.
