Halal Scanner ("the app", "we", "us") is published on Google Play and the Apple App Store by Best4Use, the maker of DeenDost. This policy explains what information the app uses, why, and the choices you have. Halal Scanner works without an account. Logging in is optional and only needed to report products.
1. Information we use

| Location (precise or approximate) | To find halal restaurants and butchers near you. | On your phone. When you look up nearby places, approximate coordinates are sent to OpenStreetMap services to return results. We do not store your location. |
| Recent scans and favourite brands | So you can see products you checked again. | On your phone only. You can clear them in the app. |
| Account details (only if you log in with Google or Apple): name, email, user ID | To let you report products and keep a count of your reports. | Google Firebase (Authentication and Cloud Firestore). |
