Prime Focus (“the app”) is a focus and screen-time tool for Android, published by Ekene Egonu, an individual developer based in the United Kingdom, trading under the name Witmynd. This policy explains what data the app handles, where that data lives, and what choices you have. We aim to keep it short and concrete — if anything is unclear, email [email protected].
1. The short version
- Prime Focus is local-first. Your usage data, schedules, and blocked-site lists stay on your device.
- We do not sell your data. We do not run third-party analytics or advertising SDKs in the app.
- Prime Focus does not currently offer cloud sync or accounts. Nothing about your usage leaves the device.
- Subscriptions are handled by Google Play. We never see your payment details.
2. What data Prime Focus uses
Prime Focus operates by reading and acting on signals from the Android operating system. The categories below describe every type of data the app touches:
Usage statistics
Provided by Android’s UsageStatsManager API with your permission. We use these to show your screen time, power streaks, and enforce per-app daily limits. This data stays on your device.
Accessibility events
Provided by Android’s Accessibility Service with your permission. We use the foreground-app signal only — to detect when a blocked app launches and to display the lock screen. We do not record screen contents, keystrokes, or personal data shown inside other apps.
Local VPN traffic (Web Guard)
When you enable Web Guard, the app creates a local on-device VPN that filters DNS lookups against your block list. Traffic stays on your device. The VPN does not route through any Witmynd server and does not log the sites you visit.
Crash diagnostics
The app includes a minimal crash reporter that records the stack trace, OS version, and Prime Focus version when a crash occurs. No screen-time data, app names, blocked sites, or personal identifiers are included. You can disable crash reporting in Settings.
3. Permissions and why we ask for them
- Usage Access — required to read screen time and enforce time limits.
- Accessibility — required to detect when a blocked app launches and to show the lock screen.
- VPN — required only if you enable Web Guard. Used to filter DNS locally; no traffic leaves your device.
- Display over other apps — required to show the lock screen on top of a blocked app.
- Notifications — required for limit reminders and schedule transitions.
- Billing — handled by Google Play Billing for Pro subscriptions. We never receive payment-card data.
You can revoke any permission at any time from Android’s Settings. Revoking a permission disables the feature that depends on it but does not delete your local data.
4. Cloud sync and accounts
Prime Focus does not currently offer cloud sync or user accounts. The app works fully offline; we do not operate any backend that holds your data.
If we add a sync feature in the future, it will be opt-in and end-to-end encrypted, hosted in the United Kingdom or the European Union. We will update this policy at least 14 days before that feature ships.
5. Sharing and third parties
We do not sell or rent personal data. We share data with third parties only in the limited cases below:
- Google Play Billing — processes Pro subscriptions on our behalf. Subject to Google’s privacy practices.
- Crash reporting — if you have not disabled it, anonymized stack traces are sent to a hosted crash-reporting service.
- Legal requests — we will respond to valid legal requests for any data we hold. Because the app is local-first, we typically hold no personal data outside crash diagnostics.
6. Data retention
On-device data lives until you delete it or uninstall the app. Crash reports are retained for 90 days. We do not retain any other personal data on our side, because we do not collect any.
7. Your rights
Under the UK GDPR and EU GDPR you have the right to access, rectify, erase, restrict, or object to processing of personal data we hold about you, and the right to data portability. To exercise these rights, email [email protected]. We respond within one month.
In practice, because the app is local-first, the only personal data we are likely to hold about you is anonymized crash diagnostics (if you have not disabled them). All other data lives on your device and is under your direct control — uninstalling the app deletes it.
If you believe we have mishandled your data, you can lodge a complaint with the UK Information Commissioner’s Office (ico.org.uk), or with your local data-protection authority if you are in the EU.
8. Children
Prime Focus is designed for adults and is not directed at children under 13. We do not knowingly collect personal data from children. If you believe we have, contact us and we will investigate and delete it.
9. International users
Prime Focus is operated from the United Kingdom. Because the app is local-first and we do not currently hold synced user data, no international transfer of personal data takes place. The crash-diagnostics service we use may process anonymized stack traces outside the UK; in that case we rely on the UK International Data Transfer Addendum to the EU Standard Contractual Clauses.
10. Changes to this policy
We may update this policy as the app changes. Material changes will be announced in-app and on this page at least 14 days before they take effect. The date at the top of this page reflects the latest revision.
