Privacy Policy

Last updated: 2026-04-09

LDigi ("we", "us", or "our") operates the ALPR Tracker - License Plate mobile application (the "Service"). This page informs you of our policies regarding the collection, use, and disclosure of personal and sensitive data when you use our Service. This policy strictly complies with Google Play Developer Policies and Google AdMob guidelines.

1. Permissions and Sensitive Data Access

To provide core license plate recognition and record-keeping features, the Service requests the following device permissions. We do not upload this data to any external servers; all processing and storage occur entirely locally on your device:

Camera Permission: Required to capture real-time video frames and perform offline Optical Character Recognition (OCR) via Google ML Kit. The camera feed is processed in real-time and is never recorded or uploaded.
Fine Location Permission: When a license plate is successfully captured, the Service reads your current GPS coordinates to append location data to your "History" log.
Device Storage: Recognized plate numbers, timestamps, geolocations, and screenshot images are saved locally in the app's secure internal storage and local database.

2. Advertising and Third-Party Services (Google AdMob)

The Service is provided as a Freemium app (with in-app purchases). We use Google AdMob as a third-party vendor to serve advertisements. To provide these ads, Google and its partners may collect and use certain information:

Advertising ID: Google accesses your device's Android Advertising ID to serve personalized or non-personalized ads.
Cookies and Usage Data: Third-party ad networks may use cookies or similar technologies to gather statistical data about your interaction with the ads.

We do not control the data collection practices of these third-party services. We strongly encourage you to review their privacy policies:

3. In-App Purchases

The Service offers a premium option to remove advertisements. All transactions are securely processed through Google Play Billing. We do not collect, process, or store your credit card details or financial data. Google Play only shares an anonymous purchase token with us to verify your premium status.

4. Data Security and Retention

We prioritize your privacy and data security:

100% Local Storage: All license plate records, locations, and images you capture are stored securely on your device.
Data Deletion: You can manually delete any record at any time within the "Database" tab. If you uninstall the Service, all local data, including historical records and photos, will be permanently destroyed and cannot be recovered by us.

5. Children's Privacy

These Services do not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13 years of age. If we discover that a child under 13 has provided us with personal information, we immediately delete this from the device or service. If you are a parent or guardian and you are aware that your child has provided us with personal information, please contact us.

6. Changes to This Privacy Policy

We may update our Privacy Policy from time to time to reflect changes in laws or our services. We advise you to review this page periodically for any changes. Changes are effective immediately after they are posted on this page.
