Privacy Policy
Dovetail · Last updated: 2026-08-16
1. What we collect
Account information (email, password hash), an adult-verification result (your date of birth itself is not stored), your profile (display name, city, bio, relationship style), compatibility answers (values and lifestyle choices with importance levels), profile photo, messages, and minimal safety logs (reports, blocks, request rates).
2. How we use it
Only to compute compatibility and matches, provide chat after a mutual match, keep the community safe (report handling, automated keyword detection, account suspension), and operate and improve the service. We do not profile you for advertising and we never sell personal data.
3. Protection of potentially sensitive data
Compatibility answers and matching activity can be sensitive by nature. Detailed answers are never shown to other users before a mutual match (only a summary and a compatibility score are visible), and profile photos are shared only with matched users via signed, expiring links after review.
4. Retention and deletion
Data is kept while your account exists. You can permanently delete your account at any time in [Settings → Privacy → Delete account]; your profile, answers, messages and photos are deleted immediately. Records we must keep by law are stored separately for the required period only.
5. Third parties and processors
We do not sell or share personal data with third parties. Our infrastructure (database, storage, authentication) runs on Supabase Inc. cloud, with data stored in the Seoul (South Korea) region.
6. Security measures
Row-level access control (RLS), hashed passwords and PINs, signed photo URLs, admin two-factor authentication, and audit logging.
7. Age requirement
This service is for adults aged 18 or older only.
8. Your rights
You may request access, correction, deletion, or restriction of your data. Most of this is available directly in the app settings; for anything else, use the contact channel below.
9. Contact
Use the in-app report feature or settings screens, or contact us at support@matgyeol.com.
10. Changes
If this policy changes, we will post the update here with a new revision date.
