KeepQR Privacy Policy

Minimal Google profile data and privacy-preserving aggregate scan counts.

1. Account & Payment Data

During Google Sign-In, KeepQR stores only basic profile fields (email, display name, Google sub ID, avatar URL). Payment instrument details are processed exclusively by Paddle (Merchant of Record) or authorized voucher marketplaces and never touch KeepQR servers.

2. Zero Tracking Cookies on QR Scanners

When visitors scan a KeepQR code, we record only aggregate daily scan counts and broad OS category (iOS, Android, Desktop) without setting tracking cookies. Abuse submissions store only a one-way SHA-256 hash of the reporter IP to prevent spam.

3. Data Deletion & Privacy Contact

Account holders may request data export or account deletion at any time by contacting support@keepqr.desiderio.kr.
