Data Retention
- Account/session/device/push/subscription records are kept while your account is active and are removed when your account is deleted.
- Session tokens expire automatically.
- Feedback submissions are retained after account deletion with account linkage removed.
- Reminder data stored in your iCloud account is controlled by Apple and your iCloud settings.
- Calendar events created by Calendar sync are stored in the calendar account you selected (for example iCloud, Google, or Outlook). If you turn off Calendar sync, existing synced calendar events may remain until removed from your calendar app. During account deletion, the app attempts to remove previously synced calendar events on a best-effort basis.
- In-app reminder history is designed around a 30-day window.
Security
We use technical safeguards including:
- HTTPS/TLS for data in transit,
- Keychain storage on iOS for local session token handling,
- authenticated access controls for protected API endpoints and webhook authorization controls.
Your Choices & Rights
You can:
- delete your account in-app,
- request deletion by email,
- manage/cancel subscriptions in Apple account settings,
- disable notifications in iOS Settings,
- sign out at any time.
To request access, correction, or deletion, contact us at the email below.
Children's Privacy
ReminderOS is not directed to children under 13.
We do not knowingly collect personal information from children under 13.
International Transfers
If you use ReminderOS outside the country where our or our providers' systems operate, your data may be processed in other countries through Apple and RevenueCat infrastructure.
App Tracking Transparency
ReminderOS does not track you across apps or websites owned by other companies as defined by Apple.
ReminderOS does not use IDFA-based advertising tracking.
Push Notifications
If you enable notifications, we process your APNs token, device-related notification settings, and timezone to deliver reminders at the correct local time.
You can disable notifications at any time in iOS Settings.
Calendar Access
Calendar sync is optional. If you turn it on, ReminderOS requests full calendar access through EventKit so you can choose a writable destination calendar and so the app can manage synced events.
- Access mode: Full access (not write-only).
- What we do with access: create/update/delete calendar events linked to reminders you sync.
- What we do not do: we do not send calendar event content to ReminderOS servers.
- Where data is handled: on your device and in your chosen calendar provider account (for example Apple iCloud, Google Calendar, or Outlook), subject to those providers' terms and privacy policies.
You can control calendar access any time:
- turn Calendar sync off in ReminderOS settings, and/or
- revoke permission in iOS: Settings -> Privacy & Security -> Calendars -> ReminderOS.
