Celtic Tree Calendar — Privacy Policy

Last updated: August 2026

Data Collection

Celtic Tree Calendar does not collect, store, or transmit any personal data. The app does not require an account, registration, or sign-in of any kind.

Network Requests

Celtic Tree Calendar does not make any network requests. Every tree, its ogham, dates, lore, kenning and correspondences are computed locally on your device from bundled data. The app functions entirely offline.

Local Data Storage

Celtic Tree Calendar stores your preference settings (such as the daily reminder toggle and time) locally on your device using standard iOS mechanisms. No personal information is stored, and this data is never transmitted.

Notifications

If you enable the optional daily reminder, notifications are scheduled locally on your device. They involve no server and no personal data, and you can turn them off at any time in Settings.

Analytics and Tracking

Celtic Tree Calendar does not include any analytics frameworks, crash reporters, advertising SDKs, or third-party tracking of any kind. We do not know who you are, where you are, or how you use the app. That is by design.

Third-Party Services

Celtic Tree Calendar does not communicate with any third-party services. There are no embedded web views, no social media integrations, no advertising networks, and no data brokers.

Children’s Privacy

Celtic Tree Calendar does not collect data from anyone, including children. The app contains no objectionable content and carries a 4+ age rating.

Changes to This Policy

If this policy changes, the updated version will be posted here with a revised date. Given that the app collects no data, changes are unlikely.

If you have questions about this privacy policy, please open an issue on the Celtic Tree Calendar GitHub repository.
