Privacy Policy — Remind My Friends
Last Updated: May 19, 2026
1. Introduction
Remind My Friends (“we,” “our,” or “the app”) is a social alarm and timer application that lets you set reminders that ring on your friends’ phones. This Privacy Policy explains how we collect, use, and protect your information.
2. Information We Collect
2.1 Account Information
- Apple ID credentials: We use Sign in with Apple for authentication. We receive your name (if you choose to share it) and email address (which may be an Apple relay address).
- Display name and username: You choose a display name and unique username during setup.
2.2 Social Data
- Friend connections: We store your friend list, including accepted, pending, and blocked relationships.
- Reminder data: We store alarms and timers you create, including target times, labels, and recipient lists. We also store acknowledgment and snooze status for each recipient.
2.3 Device Information
- Push notification token: We store your device token to deliver reminder notifications via Apple Push Notification service (APNs).
- App preferences: We store your notification preferences and onboarding completion status locally on your device using UserDefaults.
2.4 Optional Contact Discovery
- Hashed contact email addresses: If you choose to find friends from contacts, the app reads contact names and email addresses on your device. We send only SHA-256 hashes of normalized email addresses to our backend to match app users who have enabled contact discovery.
- What stays on device: Contact names, phone numbers, and raw contact email addresses are not uploaded. The app does not automatically message your contacts.
2.5 Information We Do NOT Collect
- Location data
- Contact names, phone numbers, or your full address book
- Photos, videos, or audio
- Browsing or search history
- Financial or payment information
- Health or fitness data
- Advertising identifiers
3. How We Use Your Information
We use your information solely to provide and improve the app:
- Authentication: Verify your identity and maintain your session

- Reminder delivery: Send alarms and timers to your friends’ devices at the scheduled time

We do not use your information for advertising, selling to third parties, user profiling, or training AI/ML models.
4. Data Sharing
We do not share your personal information with third parties except:
- Apple: Authentication via Sign in with Apple, push notification delivery via APNs
- Service providers: Our backend is hosted on Railway (railway.app). Your data is processed on their infrastructure to operate the service. All data is encrypted in transit via HTTPS. The backend uses a PostgreSQL database for data storage.
- Legal requirements: If required by law, regulation, or legal process
5. Data Storage and Security
