# Tidybook

> One clean address book — import from every source, deduplicate with a review queue, clean it up, and sync it end-to-end encrypted across all your devices.

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

<Steps>
  <Step title="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.
  </Step>

  <Step title="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.
  </Step>

  <Step title="Keep it everywhere">
    Turn on Sync and your tidy book stays identical across your devices — encrypted so the server
    can't read it.
  </Step>

  <Step title="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.
  </Step>
</Steps>

<Note>
  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.
