friendkeeper ("we", "our", or "the app") is committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights.
friendkeeper requires you to verify your phone number via SMS to create an account. Your phone number is used to identify your account and to allow other friendkeeper users to find you (see "Contact Discovery" below). We store your phone number securely on our servers, hosted by Supabase.
Your personal data — including friends, reminders, catch-up history, and borrowing records — is stored both locally on your device and synced to our servers so you can access it across devices. Server-side data is stored in a Supabase-hosted database with row-level security, meaning only you can access your own data.
You may optionally provide profile information including your name, email address, physical address, and date of birth. You control what is shared through privacy settings in the app. Your profile information is only ever visible to other friendkeeper users who you have saved in your device's contacts. It is never shared publicly or with users you don't know. By default, your name and birthday are shared with your contacts; email and address sharing can be toggled on or off in your privacy settings.
friendkeeper may request access to your device's contacts to help you find friends who also use the app. When you use this feature, phone numbers from your contacts are hashed (converted to an irreversible code) on your device before being sent to our server for matching. We never store or see raw contact phone numbers. We do store hashed versions of your contacts on our server to enable mutual-contact verification — your shared profile information is only visible to other users who also have you saved in their contacts. You can block specific users from finding you in the app's settings.
We use PostHog to collect anonymous usage analytics. This helps us understand how the app is used so we can improve it. Analytics data includes:
Analytics data is anonymous and cannot be used to identify you personally. No personal content (friend names, notes, photos, etc.) is ever sent to our analytics service.
The app may request permission to send local notifications for reminders, birthdays, and friendiversaries. These notifications are generated entirely on your device.
friendkeeper may request access to your photo library to let you add profile pictures for friends or photos for catch-ups and borrowed items. Photos are stored locally on your device only.
The app integrates with the following third-party services:
During setup, you may provide your date of birth (including birth year). This information is used for personalisation features such as zodiac insights. If you choose to share your birthday with contacts, the level of detail shared (month/day only, with year, or with birth time) is controlled by your privacy settings. You may also optionally store a birth year for friends you add to the app.
You can permanently delete your account and all associated data at any time from within the app by going to Settings > Delete Account. This will:
This action is permanent and cannot be undone.
friendkeeper is not directed at children under 13. We do not knowingly collect personal information from children. During setup, the app asks for your date of birth and will prevent users under 13 from proceeding. If we learn that we have inadvertently collected information from a child under 13, we will take steps to delete that information promptly. If you believe a child under 13 is using the app, please contact us at support@friendkeeper.com.
We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated "Last updated" date.
