Privacy Policy

Last updated: May 21, 2026

This Privacy Policy describes how DMOnly ("we", "our", "the app") handles your information. The short version: we don't collect any.

1. What data we collect

None. DMOnly does not collect, transmit, store on any server, or share any personal data, behavioral data, or usage data. There is no backend service, no analytics SDK, no crash reporter, and no third-party tracker integrated into the app.

2. What data stays on your device

DMOnly stores the following information locally on your iPhone using Apple's App Group storage (UserDefaults):

An opaque token representing which apps you have selected to manage (this token is provided by Apple's FamilyActivityPicker; we cannot read which specific apps it represents).
The number of 15-minute windows you have used today.
The date of the current day (for daily quota reset).
Your subscription state (Free or Pro).
Whether you have completed onboarding.

This data never leaves your device. Uninstalling DMOnly removes all of it.

3. Screen Time permission

DMOnly requests permission to use Apple's Screen Time API (Family Controls framework) so that it can lock and unlock the apps you select. This permission is granted by you directly to iOS — not to DMOnly. DMOnly does not see your activity, app usage history, screen time reports, or any other information that Screen Time tracks for you.

4. Subscriptions (StoreKit)

Pro subscriptions are processed by Apple via StoreKit. We receive a confirmation that a purchase was made, but we do not receive your payment details, name, email, or any other personally identifiable information. Apple's Privacy Policy governs how Apple handles your purchase data: https://www.apple.com/legal/privacy/

5. Children

DMOnly is intended for adult use (18+). We do not knowingly collect any information from children. The app is not designed as a parental control tool.

6. Changes to this policy

If we ever change this Privacy Policy, we will update the "Last updated" date above and post the new version at this URL. Material changes will also be announced in-app.
