Privacy Policy
Last updated: March 17, 2026
Check In Circle (“we”, “our”, or “us”) operates the Check In Circle mobile application (the “App”). This Privacy Policy explains how we collect, use, and protect your information when you use our App.
Information We Collect
Information You Provide
- Phone number: Used as your primary account identifier and for sending check-in reminders via SMS during escalation.
- Name and email address: Used for your profile and as additional contact channels during the escalation process.
- Emergency contacts: Names, phone numbers, and email addresses of people you designate to be notified if you miss a check-in.
- Check-in schedule: Your preferred check-in frequency, time, and response window.
Information Collected Automatically
- Device tokens: Push notification identifiers used to send check-in reminders to your device.
- Check-in history: Timestamps and status of your check-ins, used to determine whether escalation is needed.
- Device and platform information: Operating system type (iOS/Android) for delivering notifications correctly.
Information That Never Leaves Your Device
- Biometric data: Face ID, Touch ID, and fingerprint data is processed entirely on your device by the operating system. We never receive, store, or transmit your biometric data.
- Passcode: Your 4-digit app passcode is stored securely on your device using platform-specific secure storage. It is never transmitted to our servers.
How We Use Your Information
We use your information solely to provide the Check In Circle service:
- Sending check-in reminders via push notifications at your scheduled times.
- Verifying check-ins to determine if you’ve responded within your configured window.
- Escalation: If you miss a check-in and don’t respond within your configured response window, we contact you via push notification, SMS, and email, then notify your designated emergency contacts.
- Account management: Maintaining your profile, schedule, and contact preferences.
We do not use your information for advertising, marketing, analytics profiling, or any purpose unrelated to the core safety check-in service.
Third-Party Services
We use the following third-party services to operate the App:
| Service | Purpose | Data Shared |
|---|---|---|
| Firebase (Google) | Authentication, database, cloud functions, push notifications | Phone number, email, name, device tokens, check-in data |
| RevenueCat | Subscription management and billing | Anonymous user ID, purchase history |
| Twilio | SMS delivery for escalation and verification | Phone numbers, message content |
| Apple / Google | Push notification delivery | Device tokens, notification content |
Each third-party service processes data according to their own privacy policies. We only share the minimum data necessary for each service to function.
SMS Communications
Check In Circle uses SMS to deliver safety-critical messages, including trusted contact verification requests, missed check-in alerts, check-in recovery notifications, vault access notifications, and vault viewer verification codes. Phone numbers provided by users and their designated contacts are used exclusively for these transactional notifications.
We will never share phone numbers with third parties, sell them, or use them for marketing purposes. You will never receive promotional or marketing messages from Check In Circle via SMS or any other channel. SMS is sent only when directly required by the safety functions you or the person who designated you have configured.
Message Frequency
- Primary users: SMS is used only as a fallback when push notifications cannot be delivered. Typical frequency is 0–1 messages per day.
- Trusted contacts: SMS is sent during contact verification (one-time), missed check-in escalation events, check-in recovery notifications, and vault access notifications. Frequency depends on the primary user’s check-in schedule and is typically very low.
Opt-Out
Any SMS recipient may reply STOP at any time to immediately opt out of all future SMS messages from Check In Circle. Reply HELP for support information. When a trusted contact opts out via STOP, the primary user is notified so they can designate an alternative contact.
Message and Data Rates
Standard message and data rates may apply depending on your mobile carrier and plan.
Data Retention
- Account data: Retained while your account is active. You can request deletion at any time.
- Check-in history: Retained for the duration of your account to provide history features and verify escalation accuracy.
- Verification codes: Automatically deleted after 10 minutes or upon successful verification, whichever comes first.
- Device tokens: Removed when you log out or unregister your device.
Data Security
We protect your data using:
- Encryption in transit: All data transmitted between the App and our servers uses TLS encryption.
- Encryption at rest: Data stored in our database is encrypted at rest.
- Authentication: All API requests require valid authentication tokens.
- Access controls: Firestore security rules ensure users can only access their own data.
- On-device security: Sensitive data like passcodes and biometric templates never leave your device.
Your Rights
You have the right to:
- Access your personal data stored in the App.
- Correct inaccurate information via your profile settings.
- Delete your account and all associated data by contacting us.
- Export your check-in history data.
Children’s Privacy
Check In Circle is not intended for use by children under the age of 13. We do not knowingly collect personal information from children under 13.
Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy in the App and updating the “Last updated” date.
