Privacy Policy

Last updated: August 9, 2026

PenGain ("the app") is a weight tracking app for iOS. This policy explains what information the app handles and how.

Data Collection

PenGain does not collect, transmit, or sell any personal data. The app has no user accounts, no analytics, and no advertising.

Data Storage

All information you enter — including your weight entries, target weight, and unit preference — is stored locally on your device using Apple's SwiftData framework. This data is never sent to us or to any third party, and we have no access to it.

Notifications

If you enable the optional Daily Reminder feature, PenGain schedules a local notification on your device at the time you choose. This notification is generated and delivered entirely on-device; no data about your usage or reminders is sent to us or anyone else.

Third-Party Services

PenGain does not integrate with any third-party analytics, advertising, or tracking services.

Children's Privacy

PenGain does not knowingly collect any information from anyone, including children, because it does not collect information at all.
