Privacy Policy for CFER Study

Last updated: 2026-05-19

This Privacy Policy describes how the CFER Study mobile application ("the App", "we", "us") handles information when you use the App.

1. Information We Collect

We do not collect, transmit, or store any personally identifiable information ("PII") about you on any server we control or any third-party server. The App does not require you to create an account, sign in, or provide any personal details.

2. Data Stored on Your Device

The App stores the following data locally on your device only, using Apple's standard on-device storage (AsyncStorage / iOS user defaults):

This data never leaves your device. It is deleted when you uninstall the App. We have no ability to access, recover, or view it.

3. Third-Party Services

The App does not include any third-party analytics, advertising, crash-reporting, attribution, or tracking SDKs. The App does not make network requests to any server we operate.

4. In-App Purchases

The App offers an optional one-time, non-consumable in-app purchase ("CFER Study Pro") processed by Apple's StoreKit. Apple processes the payment and provides us with anonymized purchase confirmation. We do not see your payment method or credit card details. Restoring a purchase across devices uses Apple's Restore Purchases mechanism tied to your Apple ID; we have no separate user database.

5. Children's Privacy

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

6. Changes to This Policy

We may update this Privacy Policy from time to time. Updates will be posted at this URL with a revised "Last updated" date.
