Tarn is an iPhone app that uses Apple Screen Time to block distracting apps and websites, and to show you a summary of your progress. This policy explains what data we handle and how.
Tarn does not transmit or share any data. The app does not track you, does not use analytics, contains no third-party SDKs, and makes no network requests. Everything the app stores stays on your device.
Tarn uses Apple's Screen Time framework (FamilyControls and ManagedSettings) to apply restrictions on your device. All settings — including which apps are blocked, whether a lock is active, and the starting screen-time figure you enter for the progress card — are stored locally on your device using Apple's shared app group storage. This data never leaves your device.
Tarn requests authorization to use Apple Screen Time in individual (self-restriction) mode. This authorization is managed entirely by Apple on your device.
To show your progress, Tarn uses Apple's DeviceActivity framework to display a summary comparing your recent screen time to a starting point you enter. This summary is calculated and shown entirely on your device. The underlying usage data is provided by Apple, remains on your device, and is never sent to us or anyone else — we never receive it. Apple may independently collect data in accordance with their own Privacy Policy.
Tarn makes zero network requests. No data of any kind ever leaves your device.
Apple may independently collect data related to your use of the App Store, such as download information and crash reports, in accordance with Apple's own Privacy Policy.
If you email us for support, we will receive your email address and any information you choose to include. We use this only to respond to your request.
We may update this policy from time to time. Any changes will be reflected on this page with an updated date.
