For the QR & Barcode Reader mobile application (iOS and Android), developed by Mariia Vasylenko.
No. The QR & Barcode Reader app does not require you to register, sign in, or create an account. No user profile is stored on our servers. All scan history and app settings are stored locally on your device only.
The fastest way to remove all personal app data is to uninstall the app — this deletes all locally stored scan history and settings from your device immediately, with no further action required.
While using the app, third-party analytics services may have collected limited, mostly anonymous data tied to a device-level identifier. If you want this data deleted from our analytics providers as well, follow the steps below.
| Data category | Deleted on request | Retained (and why) |
|---|---|---|
| Anonymous analytics events (sessions, screen views, crash reports) | Yes — within 30 days | — |
| Device identifiers (Google Advertising ID / iOS IDFA), IP address | Yes — within 30 days | — |
| Approximate location (derived from IP) | Yes — within 30 days | — |
| Pseudonymous identifier used for subscription validation | Yes — once active subscriptions end | Required while a paid subscription is active to keep paid features available |
| Purchase & refund records (transaction IDs, amounts) | — | Retained up to 7 years where required by tax, accounting, and consumer-protection laws |
| Records required to resolve fraud, abuse, or legal disputes | — | Retained for the period necessary to comply with applicable law |
