DoomStop does not collect, store, or transmit any personal data. Everything stays on your device.
Overview
DoomStop is a screen-time management app that lets you voluntarily block distracting apps on your own iPhone and unlock them by tapping an NFC tag or via a set schedule. This privacy policy explains what data the app uses and how it is handled.
Data We Collect
We collect no personal data. DoomStop does not:
- Create accounts or require sign-in
- Collect names, email addresses, or any personally identifiable information
- Use analytics, crash reporting, or tracking SDKs
- Connect to any server or external service
Data Stored on Your Device
DoomStop stores the following data locally on your device only:
- App groups you create — the names and app selections you define for blocking
- NFC tag UID — the identifier of the NFC tag you register, used to verify your tag on scan
- Schedule settings — lock and unlock times you configure per group
- Lock state — which groups are currently blocked
This data is shared locally between the main app and its system extensions (Screen Time monitor, shield configuration) using Apple's App Groups mechanism. It never leaves your device.
Screen Time API (FamilyControls)
DoomStop uses Apple's FamilyControls and Screen Time frameworks to block apps you choose. This is a self-imposed, voluntary restriction — DoomStop is not a parental control app. Apple's frameworks handle app blocking at the system level. DoomStop does not have access to which apps you use, your usage statistics, or any data from blocked apps.
NFC
DoomStop uses your iPhone's NFC reader solely to read the UID (unique identifier) of an NFC tag you physically tap. This UID is stored locally on your device and is used only to verify that the correct tag was tapped during an unlock attempt. No NFC scan data is transmitted or shared.
Third-Party Services
DoomStop uses no third-party SDKs, analytics tools, advertising networks, or cloud services.
Children's Privacy
DoomStop does not knowingly collect data from anyone, including children. As no data is collected at all, there is nothing to disclose under children's privacy regulations.
Changes to This Policy
If this policy changes, the updated version will be posted at this URL. Continued use of the app after changes constitutes acceptance of the updated policy.
