PenGain ("the app") is a weight tracking app for iOS. This policy explains what information the app handles and how.
PenGain does not collect, transmit, or sell any personal data. The app has no user accounts, no analytics, and no advertising.
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.
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.
PenGain does not integrate with any third-party analytics, advertising, or tracking services.
PenGain does not knowingly collect any information from anyone, including children, because it does not collect information at all.
If this policy changes, the updated version will be posted at this URL with a revised "Last updated" date.
