Privacy Policy

Your Privacy Matters

Decarbonr is committed to protecting your privacy. This policy explains how we handle your data and what information we collect (spoiler: very little).

1. Information We Collect

Data Stored Locally on Your Device

All your carbon footprint data is stored locally on your device using SwiftData. This includes:

• Scanned food items and their carbon footprint data
• Travel entries (transportation type, distance, emissions)
• Your personal goals and settings (lifestyle, country, daily budget)
• Historical tracking data and analytics

Important: This data never leaves your device unless you explicitly use sharing features (e.g., exporting data).

Camera Access

The app requests camera permission to scan barcodes. Camera images are processed locally on your device and are not stored or transmitted anywhere.

API Requests

When you scan a barcode, the app makes an anonymous request to the OpenFoodFacts API to retrieve product information. These requests do not contain any personal information about you.

2. What We Don't Collect

• No personal identification information (name, email, phone number)
• No location data
• No usage analytics or tracking
• No advertising identifiers
• No behavioral tracking
• No data is sent to third-party servers (except OpenFoodFacts API)

3. Third-Party Services

OpenFoodFacts

Decarbonr uses the OpenFoodFacts API to retrieve product information when you scan barcodes. OpenFoodFacts is a non-profit, open-source food products database.

• API requests are anonymous
• No personal data is shared with OpenFoodFacts
• View OpenFoodFacts privacy policy: https://world.openfoodfacts.org/privacy

App Store

If you download the app from the Apple App Store, your interaction with the App Store is governed by Apple's privacy policy, not ours.

4. Data Security

Your data security is paramount:

• All data is stored locally on your device using iOS secure storage (SwiftData)
• Your device's security features (passcode, Face ID, Touch ID) protect your data
• No data is transmitted to external servers (except anonymous API requests)
• Data is not backed up to cloud services unless you enable iCloud backup on your device

5. Your Rights

Since all data is stored locally on your device, you have complete control:

• Access: All your data is visible within the app
• Delete: You can delete individual entries or all data from Settings
• Export: You can export your data for personal use
• Portability: Your data can be exported in standard formats
• Complete removal: Uninstalling the app deletes all local data

6. Children's Privacy

Decarbonr does not collect any personal information from anyone, including children under 13. The app is designed for general audiences and focuses on environmental education.

7. Changes to This Policy

We may update this privacy policy from time to time. We will notify you of any changes by updating the "Last updated" date at the top of this policy. Continued use of the app after changes constitutes acceptance of the updated policy.

8. GDPR Compliance

For users in the European Union, we comply with GDPR regulations:

• Legal basis for processing: Legitimate interest and user consent
• Data minimization: We only process data necessary for app functionality
• Purpose limitation: Data is used only for carbon tracking features
• Storage limitation: You control data retention through the app
• Right to be forgotten: Delete the app to remove all data

9. California Privacy Rights (CCPA)

For California residents:

• We do not sell your personal information
• We do not share your personal information for cross-context behavioral advertising
• We do not collect sensitive personal information beyond what's necessary for app functionality
