Privacy Policy — Sketch Focus

Last updated: May 2026 · Applies to iOS & Android

The short version

Sketch Focus does not collect, store, transmit, or share any personal data or device information — ever. No account required. No tracking. No analytics. Everything stays on your device.

1. About Sketch Focus

Sketch Focus is a focus timer app developed by Core Tattva. You set a timer, stay on task, and the app progressively draws a sketch stroke by stroke as your session runs. When your focus session completes, you're rewarded with a finished piece of art. The app is entirely self-contained and works without an internet connection.

2. Data We Collect

We collect no data whatsoever. Sketch Focus does not collect, process, or store any personal information, usage data, analytics, crash reports, device identifiers, or any other information from you or your device.

3. Account & Login

Sketch Focus requires no account, login, or sign-up of any kind. You can download and use the app immediately without providing any personal information.

4. Internet Access

Sketch Focus does not require or use an internet connection. The app functions entirely offline. No data is transmitted to any server, third party, or external service.

5. Third-Party Services

Sketch Focus does not integrate any third-party SDKs, analytics tools, advertising networks, crash-reporting services, or social login providers. There are no third parties who could receive your data from this app.

6. Device Permissions

Sketch Focus does not request access to your camera, microphone, contacts, location, photos, notifications, or any other sensitive device permissions beyond what is minimally required by the operating system to run a foreground timer application.

7. App Blocking

Sketch Focus offers an optional "Block Apps" feature that helps prevent distracting apps from being used during an active focus session. The implementation differs by platform.

iOS

When you use the optional "Block Apps" feature on iOS, Sketch Focus uses Apple's Family Controls and Screen Time framework. The apps and categories you choose to block are stored as opaque tokens issued by iOS — Sketch Focus cannot see or read which specific apps you selected. These tokens are kept only on your device, never transmitted, and never shared with us or any third party. Selections are cleared when you uninstall the app.

Android

On Android, the optional "Block Apps" feature requires the Usage Access and Display Over Other Apps permissions to detect which app is in the foreground and to render the blocking overlay. Sketch Focus only uses these permissions during an active focus session, never logs which apps you opened, and never transmits this data anywhere.

8. Advertising

Sketch Focus contains no advertising of any kind. There are no ads, no ad SDKs, and no ad-related data collection — ever.

9. Children's Privacy

Because we collect no data from any users, Sketch Focus is safe for users of all ages. We do not knowingly collect any information from children under 13 (or the applicable age of digital consent in your jurisdiction).

10. Changes to This Policy

If we ever update this privacy policy, we will post the revised version here with an updated date. Any future version of Sketch Focus that does collect data will clearly disclose what is collected and why, prior to any data being gathered.
