• Price Information: The prices you enter for products are stored locally on your device.

• Quantity & Descriptions: Optional notes you add about products.

• Location Data (Optional): If you enable location recording, we store approximate coordinates (5 decimal places, ~1.1m accuracy) to remember shop locations. This is disabled by default.

1.2 Data Collected Automatically

• App Usage Data: Anonymous usage statistics to improve the App.

• Device Information: Device type, operating system version, for compatibility purposes.

• To search and analyze your price history

• To export your data in CSV format when requested

• To display relevant advertisements (see Section 5)

3. Data Storage & Security

3.1 Local Storage

All your price records, barcode data, and location information are stored locally on your device in a CSV file. We do not upload this data to any servers.

3.2 Data Export & Backup

You can export your data to your device's Downloads folder at any time using the Export feature in Settings. We recommend you back up this file regularly.

3.3 Data Deletion

You can delete your data by:

4. Third-Party Services

When you scan a barcode, we may query the Open Food Facts database (world.openfoodfacts.org) to retrieve product names, with only the barcode, no other information uploaded. This service has its own privacy policy.

4.2 Google Services

The App uses Google Play Services for location data (when enabled). Google's privacy policy applies to their services.

5. Advertising

5.1 AdMob by Google

We use Google AdMob to display advertisements in the App. AdMob may collect:

• Device advertising identifiers

• Approximate location (country/city level)

• App usage data

This information is used to show relevant ads and measure ad performance. You can learn more about how Google uses data for advertising at Google's Advertising Policies.

5.2 GDPR/CCPA Compliance for EU & California Users

For users in the European Union and California:

• We show a consent form for personalized ads where required

• You can opt out of personalized ads through the consent form

• We honor "Do Not Sell My Personal Information" requests

To opt out of personalized ads globally, you can reset your advertising identifier in your device settings (Android: Settings → Google → Ads → Reset advertising ID).

6. Permissions
