Delete your data
Data on your phone
QR Code Scanner & Generator has no accounts. Scan history, codes you create, wallet cards, logos and settings are stored only on your phone. Camera frames are never saved.
To delete that data:
- Delete single scans, or clear all history in Settings. You can also set history to auto-delete after 30 or 90 days.
- Android Settings › Apps › QR Code Scanner & Generator › Storage › Clear storage, or
- uninstall the app.
Files you exported (CSV, JSON, images, PDF or SVG) are not touched; delete them where you saved them.
Crash reports and analytics (Firebase)
The app sends crash reports (Firebase Crashlytics) and general usage analytics (Firebase Analytics), linked to a random app installation ID and the advertising ID, not to your name or e-mail. To have this data deleted:
- E-mail tecdroiddeveloper@gmail.com with the subject “QR Code Scanner & Generator data deletion request”. If you can, include the app instance ID shown in the app’s About screen.
- We reply within 30 days and delete the crash and analytics data we can match to your request in Firebase. Because the app has no accounts, we may ask for details such as the date and time you used the app or your phone model to find it.
Without a request, Firebase deletes this data automatically: crash reports after 90 days and user-level analytics data after 2 months. You can also reset or delete your advertising ID in Android Settings › Google › Ads (or Settings › Privacy › Ads).
What is kept
We keep no other copy of your data, and we never sell or share it. Files you saved or exported yourself remain only where you put them.
