Privacy Policy
Last updated: May 16, 2026
Summary: E Numbers Scanner is designed with privacy in mind. All data is stored locally on your device. We do not collect, transmit, or share your personal information.
Introduction
Welcome to E Numbers Scanner ("we," "our," or "us"). We are committed to protecting your privacy and ensuring you understand how your data is handled when using our mobile application.
This Privacy Policy explains our practices regarding the collection, use, and disclosure of information when you use E Numbers Scanner.
Information We Collect
We do not collect any personal information. E Numbers Scanner operates entirely offline and locally on your device. Specifically:
- Camera Access: Used solely to capture images of food labels for scanning. Images are processed locally and never uploaded to any server.
- Photo Library Access: Used only when you choose to import an image for scanning. Selected images are processed locally.
- Scan History: Your scan history is stored locally on your device and is never transmitted externally.
- App Settings: Preferences such as language selection are stored locally on your device.
How We Use Your Information
Since we don't collect personal information, there is no data used for:
- Marketing or advertising
- Analytics or tracking
- Sharing with third parties
- User profiling
All processing occurs locally on your device to provide you with additive information and safety ratings.
Data Storage
All data generated by the app is stored locally on your device:
- Scan Images: Saved in the app's private storage directory
- Scan History: Stored in a local SQLite database
- Preferences: Stored using the device's local storage system (SharedPreferences)
You can delete all stored data at any time through the app's Settings screen or by uninstalling the application.
Third-Party Services
E Numbers Scanner uses the following third-party technologies that operate locally on your device:
- Google ML Kit: Used for on-device text recognition (OCR). All processing occurs locally; no data is sent to Google servers.
- Google AdMob: Free users may see ads to support continued development. AdMob may collect device identifiers in accordance with Google's Privacy Policy. Premium users see no ads.
- Firebase Analytics & Crashlytics: Used to understand app stability and usage patterns. No personally identifiable information is collected.
In-App Purchases
E Numbers Scanner offers a one-time premium purchase to remove all ads and unlock unlimited scans. Purchase transactions are handled entirely by Apple App Store or Google Play and are subject to their respective privacy policies. We do not receive or store any payment information.
Children's Privacy
E Numbers Scanner does not knowingly collect any personal information from anyone, including children under the age of 13. The app is safe for users of all ages.
Data Security
Since all scan data and history remain on your device, the security of your information depends on your device's security measures. We recommend:
- Using a device passcode or biometric lock
- Keeping your device's operating system updated
- Only downloading apps from official app stores
Your Rights
You have complete control over your data:
- Access: View your scan history anytime within the app
- Deletion: Clear all data through Settings or by uninstalling the app
