DaysUntil has no developer account, advertising or analytics SDK. The developer does not receive saved content through the app.
Events and preferences are stored in local app storage. Pro users can enable private iCloud event sync when the required account is available. The developer does not receive the synced event library. Removing the app can remove local data. Device backup and restoration depend on system settings and the backup provider.
Optional Pro event sync uses the user's private Apple iCloud key-value store. The required account and cloud availability are managed by Apple. An iCloud copy may remain after an app is removed from one device. Photo backgrounds stay in local storage and are not included in event sync. Optional reminders use local system notifications. Photo selection and notification permissions are managed by the operating system.
StoreKit provides product information, purchases, restoration and verified entitlement checks. These services may communicate with Apple and require a connection. The app uses entitlement information to unlock paid features and does not receive payment card details. Apple's privacy policy applies to its services.
External links and deliberately shared content are handled by the destination you select. If you contact support, the developer receives what you send. Updates to this policy appear here with a revised date.
