Privacy Policy
Last updated: November 10, 2026
This privacy policy explains how the iOS app Screen Time Blocker (the “app”) processes personal data.
1. Controller
Rene Arnegger, Tapify Labs
Postal address: see Imprint
Email: r.arnegger@googlemail.com
2. Data stored only on your device
The app stores the following data locally on your device (in an on-device database):
- Your onboarding answers (for example your motivation and usage habits)
- Your blocking rules: which apps, categories or websites should be blocked and when (stored as anonymous Apple tokens, see section 3)
- Block events: when a blocked app was opened, so the app can show you your own statistics
- Settings such as language and appearance
This data is not uploaded to us or to any server. It is removed when you delete the app. It may be included in your device backups (iCloud or computer) according to your own iOS settings.
3. Apple Screen Time (Family Controls)
To block apps, Screen Time Blocker uses Apple's Screen Time frameworks (Family Controls, Device Activity, Managed Settings). You grant this access once in iOS and can revoke it at any time in the iOS Settings app under Screen Time.
- You pick apps, categories and websites in Apple's own system picker. iOS gives the app only anonymous tokens, not the names of the apps you choose.
- Your app usage is evaluated by iOS on your device. We do not receive your screen time, your usage history or a list of your installed apps.
- Screen Time data never leaves your device and is not sent to us or to any third party (including analytics and crash reporting).
4. Usage statistics (PostHog)
To understand which features are used and where people get stuck, the app sends pseudonymous usage events to PostHog (PostHog Inc., USA), using PostHog's EU cloud hosted in Frankfurt, Germany. Events include which screens you open, onboarding progress, settings changes, and paywall and purchase events. No information about which apps you block, your app usage or your screen time is sent.
Each event is linked to a random ID generated by the app, not to your name, email or Apple ID. PostHog also receives technical data such as device model, iOS version, app version, language and an approximate location (country/region) derived from your IP address. We do not combine this data with other sources. Legal basis: our legitimate interest in improving the app (Art. 6(1)(f) GDPR). You can object at any time by emailing us.
5. Crash and error reports (Sentry)
If the app crashes or an error occurs, a report is sent to Sentry (Functional Software, Inc., USA). It contains technical information such as the error message, stack trace, the screens visited shortly before the error, device model, iOS version, app version and performance measurements. We do not deliberately attach your entries to error reports. Legal basis: our legitimate interest in a stable, secure app (Art. 6(1)(f) GDPR).
6. Purchases and subscriptions
The app offers an optional subscription (Screen Time Blocker Pro). Payment is handled entirely by Apple; we never see your payment details. To check whether your subscription is active, the app uses RevenueCat (RevenueCat, Inc., USA).
| Recipient | Purpose | Data |
|---|---|---|
| Apple (App Store) | Payment, billing, refunds | Your Apple ID purchase and transaction data, managed by Apple |
| RevenueCat | Checking and restoring your subscription status | Random app user ID, purchase receipt, product, purchase and renewal dates, country, device and app version |
Legal basis: performance of the contract (Art. 6(1)(b) GDPR).
7. Notifications
Screen Time Blocker uses notifications, for example, to start the short pause before a blocked app opens, or to remind you before your trial ends. Notifications are scheduled locally on your device; no push server is involved. Notification permission is optional and can be changed at any time in the iOS Settings app.
8. Sharing and contacting us
If you share content from the app, iOS's share sheet is used; we do not receive what you share or with whom. If you email us, we use your email address and message only to answer you (Art. 6(1)(b) or (f) GDPR) and delete it when no longer needed.
9. No advertising, no tracking, no sale of data
The app contains no advertising, does not track you across other companies' apps or websites (no “tracking” within the meaning of Apple's App Tracking Transparency) and we do not sell or rent personal data.
10. Transfers outside the EU
PostHog, Sentry and RevenueCat are US companies. Where personal data is transferred to the USA, this is based on the EU-U.S. Data Privacy Framework and/or the EU Standard Contractual Clauses (Art. 45, 46 GDPR).
11. Retention and deletion
Data on your device stays there until you delete it in the app or delete the app. Usage statistics and crash reports are kept only as long as needed for their purpose and then deleted or anonymised. Purchase records are kept as long as required by statutory retention obligations. Because we cannot link usage data to you without your random app ID, please contact us if you want us to delete it; we will help you find it.
12. Children
The app is not directed at children under 13, and we do not knowingly collect data from children.
13. Your rights
Under the GDPR you have the right to access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and to object to processing based on legitimate interests (Art. 21). You also have the right to lodge a complaint with a data protection supervisory authority, in particular in the EU member state where you live. To exercise your rights, email us.
14. Changes
We update this policy when the app or the legal situation changes. The current version is always available on this page.
