Tidybook turns the mess your contacts have become into one clean, canonical address book. Import from your phone and from vCard / CSV files, merge the duplicates with a review queue that never changes anything behind your back, and keep the result identical on every device — offline-first and end-to-end encrypted, so the server only ever sees ciphertext. You buy it once; cloud sync is an optional add-on, with no subscription required to use the app.

​
The idea in one minute

1

Bring your contacts in

Import from your phone or from a vCard / CSV file. Everything lands in one high-fidelity book — no account required to start.
2

Tidy them up

Tidybook finds duplicates and queues them for your review. Merge with one tap, clean up numbers and formatting, and undo anything you change your mind about.
3

Keep it everywhere

Turn on Sync and your tidy book stays identical across your devices — encrypted so the server can’t read it.
4

Share your own card

Build a card from your own details and let anyone scan it as a QR code — no app required on their end.
Tidybook is offline-first and private by default: your book lives on your device, and anything that reaches the cloud is end-to-end encrypted — the server only ever stores ciphertext.
