Privacy Policy - BlackStar QR Scanner

1. Principle

BlackStar QR Scanner does not store or transfer personal data to its own servers. If data is stored inside the app, it is stored locally on your device.

Website and free code generator

The code generator on this website processes entered content for QR codes and barcodes only locally in your browser. Title, description and code content are not transferred to our own servers and are not stored. The website itself does not use AdMob ads; advertising information in this policy refers to the Android app.

2. Camera

The camera is used only to scan QR codes and barcodes. Camera images are not saved as photos, not transferred to our own servers and not shared with third parties by BlackStar Apps.

3. Gallery and photos

The app accesses only images you select yourself in order to scan a QR code or barcode. Image data is processed locally on the device. Photos are not stored, uploaded or shared with third parties by BlackStar Apps. Only detected scan contents may be stored in the local app history if you use the history feature.

4. History, library and My Codes

Scan results, created codes, cards, folders, previews and "My Codes" entries are stored locally on your device. These data are not automatically transferred to BlackStar Apps servers. You can delete saved content in the app.

If you create a local backup, the backup file may contain saved codes, cards, drafts, history, "My Codes" entries, local preview images and design files. The backup is saved only as a file selected by you. It is not automatically uploaded to BlackStar Apps servers. If you store or share the file using a cloud app, email app or another app, the privacy terms of the respective provider apply. When restoring a backup, only the backup file selected by you is read locally in the app. The locally stored ad-free time is not included in the backup.

Daily QR tips are provided locally inside the app. If you enable the optional reminder, the app schedules a local notification on your device. Tip contents are not transferred to BlackStar Apps servers.

5. Contacts

If you import contact data in the generator, the app accesses your contacts only after your permission. Selected contact data is processed locally to create a QR code or card. Contacts are not uploaded and not sent to BlackStar Apps servers.

6. Location

If you use the "own location" feature, the app may access your current location after your consent. Location data is used locally to enter coordinates, an address or location details into a QR code or card. Depending on your device, conversion between address and coordinates may use the operating system's geocoding service.

If you open a location in a maps app, the request is handed over to the maps app or its provider.

7. Advertising

The app uses Google AdMob to display ads. Google may collect, process and share information such as device data, advertising ID, approximate location data, app interactions, diagnostics and technical information with advertising partners or connected services. Depending on your region and consent, ads may be personalized or non-personalized.

Optionally, users may watch a rewarded video to pause ads for a limited time on the respective device. The information until when ads are paused is stored locally on the device. If app data is deleted or the app is uninstalled, this local information may be lost.

Optionally, ads can be removed permanently with a one-time purchase through Google Play. Payment processing is handled by Google Play. BlackStar does not process payment data such as payment methods, card data or bank details. The app only checks via Google Play Billing whether the purchase is active for your Google Play account and stores locally whether ads have been permanently removed. The purchase can be restored through Google Play.

The app uses the Google User Messaging Platform to show advertising and privacy choices when Google provides them for your device or region.

8. Firebase Analytics and usage analysis

The app uses Google Analytics for Firebase to better understand app usage, improve usability and measure the performance of Google Ads campaigns. Technical and usage-related information may be processed automatically, such as app launches, app opens, app updates, sessions, session duration, operating system, device model, approximate region, app interactions, app instance ID and, where available, the Android advertising ID.

The app also logs selected events, for example successful scans, created, saved, shared or downloaded codes, opened product searches, opened links, selected generators or templates, help topics and feedback categories.

The actual QR code contents, web links, email addresses, phone numbers, barcode values, contact contents, location values, addresses or freely entered texts are not sent to Firebase as Analytics events. Events are logged only with general categories and technical parameters.

Processing is performed by Google. Depending on your region, consent and Google settings, usage for analytics, campaign measurement and advertising features may be limited or adjusted.

9. External services for additional information

Scanning itself happens locally on the device. For optional additional features, detected contents may be transferred to external services. External requests use HTTPS where the respective service supports it:

These requests are made only for the respective feature. BlackStar Apps does not use own user accounts or own servers for these requests.

10. Local crash reports

After a crash, the app may save a crash report locally on your device. This report contains technical information such as app version, Android version, device model, thread, error message and stack trace. The report is not sent automatically. You can view and copy it if you voluntarily want to send it to support.

11. Open-source fonts and licenses

The app includes embedded open-source fonts for card designs. These fonts do not process personal data. The related license texts are included in the app.
