Privacy policy

StitchTick (Clean Screen Apps) works offline. There are no accounts, no servers, and your projects, counts and calculations never leave your phone. Effective 2026-10-13.

None. The app does not collect or sell personal information. It keeps on your phone your projects (names, counters, notes and work time), what you last entered in each calculator, a history of your calculations, your settings and, if you share the app from Settings, the date until which ads are hidden as a thank-you. None of it is sent anywhere. You can delete projects and history in the app, and uninstalling the app deletes everything. If you save a backup file, you choose where it goes (email, Drive, files); the app never uploads it.

The free version shows a banner ad from Google AdMob. Google may collect your device’s advertising ID, approximate IP-based location and usage data to serve and measure ads. In the EEA, the UK, Switzerland and the US states that require it, we ask for your consent or offer privacy choices before personalized ads are shown. You can reset or delete your advertising ID in Android settings. Learn more: https://policies.google.com/technologies/partner-sites

If you buy “Remove ads”, Google Play processes the payment. We never see your card or payment details; the app only asks Google Play whether your Google account owns the purchase and remembers the answer on your phone.

The StitchTick website is a set of static pages: it sets no cookies of its own, runs no analytics or ads, and what you type into its calculators stays in your browser.

The app is not directed to children under 13.

If this policy changes, the new version will be posted on this page with a new date.
