Daybook

Signing in is optional — Daybook works fully without it. With no login, nobody at Dhruvanta can see anything: your diary stays only in your own Google Sheet, and your Apps Script URL and API key stay only on this device.

Signing in does not change or gate setup — step one is still just saving your Apps Script URL and API key below. All it adds is optional: Sync credentials, so a signed-in device can restore that same connection automatically instead of you re-entering it by hand, and — where it is available — the choice to keep your diary in Dhruvanta cloud instead of your own Sheet.

1. Create your Sheet and paste the script (about 5 minutes) — guided setup
2. Paste your Web App URL and API key below
3. Press Test connection, then start adding entries

Don't have a Web App URL or API key yet? The guided setup walks through getting both, step by step, in about 5 minutes.

One-time backend setup

When you keep your diary in your own Google Sheet, Daybook has no server for it — a Google Sheet plus a small Apps Script is the entire backend, and it's free. Each person deploys their own copy. See the guided setup for the exact steps, or docs/SETUP.md and docs/API_CONTRACT.md at the repo root for the full reference.

Privacy

In Google Sheet mode (the default), the URL and API key are stored in this browser (localStorage) and sent directly from your device to your own Apps Script deployment. If you never sign in, nothing passes through any third-party server at all. If you sign in and choose Dhruvanta cloud, your entries are kept by Dhruvanta instead. If you choose to sync (above), Dhruvanta additionally stores an encrypted copy of that same URL and key — see the full policy for exactly what that does and does not mean.
