Privacy Policy

1. Who we are

CartSnap ("the app") is developed and published by Denimar Fernandez, a solo independent developer ("we," "us," "our"). You can reach us at hello@cartsnap.cc.

2. What CartSnap is

CartSnap is a grocery run calculator that uses an on-device model to read price tags and help you track your spending. It is free to download and use from the Apple App Store. There is no subscription or user account.

3. Data we collect

We do not collect, store, transmit, or share any personal data. Specifically:

• Camera images: Photos captured for price scanning are processed entirely on your device by a local AI model. They are never uploaded to any server. Unless you explicitly choose to save a photo, it is discarded after processing.
• Shopping data: Your cart items, prices, trip history, and preferences are stored locally on your device only. We have no access to this data.
• AI processing: All recognition and text extraction happens on-device. Nothing is sent to a cloud API or third-party service.
• Analytics: We do not use analytics, tracking pixels, telemetry, or crash reporters that transmit user data.
• Advertising: The app contains no ads and no advertising SDKs.
• Account data: There is no sign-in, no user account, and no profile. We do not know who you are.

4. App Store distribution

Apple distributes CartSnap through the App Store.

• CartSnap does not receive your Apple ID credentials, payment details, or billing address.
• Apple may provide aggregated App Store data, such as download counts by country. We cannot use this information to identify an individual user.

5. Network activity

CartSnap downloads the on-device scanning model from our hosting provider when you first enable scanning. We do not use this download for analytics or build user profiles. The hosting provider may process standard connection data, such as an IP address, to deliver the file and protect its service.

After the model is downloaded, the app operates fully offline. You can confirm this by using the app in airplane mode.

6. Permissions

CartSnap requests the following device permissions:

• Camera: Required to scan price tags. Camera frames are processed locally and are not stored permanently unless you explicitly save a scan.
• Storage: Used to store the on-device AI model and your local trip history.

We do not request access to your contacts, photo library, location, microphone, or any other sensitive data.

7. Third-party services

CartSnap does not integrate with any third-party analytics, advertising, social, or data-collection SDK. The only third parties involved in your use of the app are:

• Apple, for app distribution and payment processing (governed by Apple's Privacy Policy).
• Our model-hosting provider, which serves the one-time AI model download. No personal data is exchanged.

8. Data storage and deletion

Trip history, preferences, and the downloaded scanning model are stored locally on your device. Uninstalling CartSnap removes the app's local data from your phone. Because we never receive your shopping data, there is nothing on our side to delete.

9. Children's privacy

CartSnap is not directed at children under 13. We do not knowingly collect information from anyone, including children.

10. Your rights

Because we do not collect personal data, there is no user data for us to access, export, correct, or delete on your behalf. All of your CartSnap data lives on your device and is under your direct control.

11. Changes to this policy

If a future feature changes how CartSnap handles data, we will update this page with a revised date. Where required, the app will ask for your permission before enabling that feature.
