Privacy

Your calendar and events

The calendar’s settings (dates, sizes, margins, language…) and the events you write are stored only in your browser’s local storage (localStorage) on this device. They are never sent to a server of ours: we have none. The calendar is drawn and printed on your own device.

Anyone with access to this browser can see them, like anything else it keeps. To delete them, clear this site’s data in your browser’s settings.

Google Drive sync (optional)

If you turn it on in Settings, the app saves an encrypted copy of your settings and events in your own Google Drive, in a hidden folder only this app can see (Google’s drive.appdata permission: it can’t see any of your other files). It is compressed and encrypted on your device (AES-256) with a random sync key before it leaves, so Google stores only unreadable data; without the key nobody can open it, not even Google or us.

The key is kept in the local storage of each device you connect. To add another device, the app shows it as a QR code and a recovery code. The QR opens the app with the key in the part of the address after “#”, which browsers never send to any server; the app reads it on arrival, keeps it only for that browser tab until you connect, and removes it from the address bar.

Google gives the app a short-lived access token (one hour) that stays in your browser’s memory; we never receive it. Local storage also notes whether Drive is connected and when it last synced. Disconnect any time in Settings, and delete the Drive copy in Google Drive → Settings → Manage apps.

This app’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy (https://developers.google.com/terms/api-services-user-data-policy), including the Limited Use requirements. The app uses Drive only to store and read back your own encrypted copy: no ads, no AI training and no sharing with anyone.

Hosting

Cloudflare hosts the site. Like any web host it processes your IP address and technical details of each request to deliver the pages and protect them from attacks (https://www.cloudflare.com/privacypolicy/). It doesn’t see your calendar or events: the app sends it nothing.

Advertising

The site may show Google AdSense ads, which use cookies or identifiers to serve and measure ads and, if you allow it, to personalise them. Google asks for your consent where the law requires it, and you can change your choice with the “Privacy and cookies” link in the app’s footer. Ads are never printed and never see your events.

Your rights

As we don’t keep your data, there is nothing we could look up, correct or delete for you: you control it all from your browser (and the Drive copy, if any, from Google Drive). This site is run by nubuza; for any question, write to us through nubuza.com.
