Privacy Policy

Last updated: April 5, 2026

What stays on your device

App usage history, blocking rules, settings, and Wi-Fi network names are stored only in a local database on your device. None of this is ever sent anywhere.

What we send

Only anonymous crash reports and the following interaction events: how far you got in the setup flow, whether you created/edited/deleted a rule (not the rule's contents), and purchase screen views. That's it. No personally identifiable information, no app usage history, no rule contents, no Wi-Fi names. We do not sell or share data with anyone.

Permissions

• Accessibility Service — Detects which app is in the foreground to show a block screen. Does not read screen content, passwords, or touch input.
• Usage Access — Reads app usage history for the timeline screen.
• Display Over Other Apps — Shows the block overlay.
• Location — Android requires this to read Wi-Fi SSIDs. We never collect actual GPS or network-based coordinates.
• Internet — Sends crash reports and analytics only.
• Battery Optimization / Boot Completed — Keeps the monitoring service running.

Deleting your data

Delete usage history from Settings at any time. If you have Android's auto-backup enabled, some data (rules, settings) may be backed up to your Google account and restored on reinstall. To fully remove everything, clear the app's data before uninstalling.

Changes

If we update this policy, we will revise this page.
