Feevio is designed with your privacy in mind.

Data Collection

Feevio does not collect, transmit, or store any personal data. Specifically:

• No analytics or tracking — We don’t use any analytics frameworks or tracking pixels.
• No accounts — There is no sign-up, login, or user profile of any kind.
• No third-party data sharing — Your data is not shared with anyone.

Advertising

The free version of Feevio displays banner ads served by Google AdMob. AdMob may collect device identifiers and usage data in accordance with Google’s Privacy Policy. Upgrading to Feevio Premium removes all ads and any associated data collection by the ad SDK.

On-Device Storage

This data is stored in an App Group shared between the iOS app and the Apple Watch companion app. This data never leaves your device and is not accessible to us or any third party.

In-App Purchases

Feevio uses Apple’s StoreKit for in-app purchases. Purchase transactions are handled entirely by Apple. We do not process or store payment information.

Children’s Privacy

Feevio does not knowingly collect data from anyone, including children under 13.
