Data Deletion

QR Sphere stores only the following data, and all of it is kept locally on your device:

QR Scan History — A list of QR codes you have scanned, including the decoded content, timestamp, and format. Stored using Android SharedPreferences.

Barcode Scan History — A separate list of barcodes you have scanned, stored the same way.

App Settings — Your preferences for beep on scan, vibrate on scan, and theme mode. Stored using Android SharedPreferences.

Downloaded QR Images — Any QR code images you chose to download are saved to the "QR Sphere" folder in your device's Downloads directory.

No personal information, no account data, and no identifiers are stored anywhere.

You can delete your data at any time directly within the app:

TO DELETE QR SCAN HISTORY:

1. Open the app and go to the Scan QR tab.
2. Scroll down to the "Recent Scans" section.
3. Tap the delete icon next to any individual item to remove it, or tap Clear All to wipe the entire QR history.

TO DELETE BARCODE SCAN HISTORY:

1. Open the app and go to the Barcode Reader tab.
2. Scroll down to the "Recent Scans" section.
3. Tap the delete icon next to any item, or tap Clear All to wipe all barcode history.

TO DELETE DOWNLOADED QR IMAGES:

1. Open your device's Files or Downloads app.
2. Navigate to the QR Sphere folder inside Downloads.
3. Select and delete any or all images stored there.

Uninstalling QR Sphere from your device will permanently delete all locally stored data, including all scan history and app settings.

Downloaded QR images saved to your Downloads folder are not automatically removed when uninstalling. To delete those, navigate to the "QR Sphere" folder in your Downloads directory and delete the files manually before or after uninstalling.

1. Long-press the QR Sphere icon on your home screen or app drawer.
2. Tap Uninstall and confirm.
3. All scan history and settings are permanently erased.

You can also clear all stored data without uninstalling the app through Android's built-in storage settings:

1. Go to your device's Settings → Apps.
2. Find and tap QR Sphere.
3. Tap Storage.
4. Tap Clear Data. This permanently deletes all scan history and settings stored by the app.

Because QR Sphere does not collect or transmit any personal data, there is no data stored on any server or database to request deletion of. All of your data exists exclusively on your own device.

We have no user accounts, no cloud storage, and no backend systems that hold anything about you. The steps above are the complete and only data deletion process required.
