OneDay ("we", "our", or "the app") is a habit tracking application for macOS and iOS. We are committed to protecting your privacy. This policy explains how we handle your information.
OneDay does not collect, store, or transmit any personal data to external servers. All your habit data is stored locally on your device and synced privately through your personal iCloud account if you choose to enable iCloud sync.
All habit data, preferences, and settings are stored locally on your device. If iCloud sync is enabled, your data is stored in your private iCloud container, which is encrypted and accessible only to you through your Apple ID.
OneDay does not use any third-party analytics, advertising, or tracking services. We do not share your data with any third parties.
We do not collect any usage analytics or crash reports. The analytics features within the app (streaks, completion rates, etc.) are computed entirely on your device and never leave it.
OneDay does not knowingly collect any personal information from children. Since we do not collect any personal data from any user, the app is safe for users of all ages.
We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated revision date.
