The App

A calendar you'll actually want to open.

Thirteen months. Twenty-eight days each. Every month named after a sacred tree — with its own Ogham character and quiet teaching. Your events stay on your device. Google Calendar sync is optional.

Privacy & Data

Your data stays yours.

Roots Calendar is a Celtic Tree Calendar app for iOS and Android. All your events are stored locally on your device. No account is required.

Google Calendar Sync
If you choose to connect Google Calendar, the app requests read and write access to your Google Calendar events. This access is used solely to display your existing Google Calendar events alongside the Celtic calendar, and to optionally sync events you create in Roots Calendar back to Google Calendar. This feature is entirely optional — the app works fully without it.
What We Don't Do
Roots Calendar operates no server or backend. Your events and Google Calendar data are never sent to Blu8print or any third party. All Google API calls go directly from your device to Google's servers. We do not collect, sell, or share your personal data.
