Effective date: June 10, 2026
hrkltz ("we", "us", or "our"), as the provider of Astryn for iOS ("App"), is committed to protecting your privacy. This Privacy Policy explains how we handle information for the App. For the accompanying website astryn.hrkltz.io, please refer to our shared Website Privacy Policy.
Our App does not collect, store, or share personal data through our own analytics, advertising, or tracking systems. We do not operate a backend that stores your in-app personal data. Your feeds, reading habits, and tag graph remain on your iPhone.
iOS may collect analytics, diagnostic, and usage information at the operating-system level. Depending on your device settings (for example, "Share iPhone & Watch Analytics" and "Share With App Developers"), Apple may receive diagnostic data and may share certain diagnostic information with developers. This data handling is controlled by Apple and governed by Apple's own privacy terms.
Our App is designed to keep your data local to your device as much as possible. However, iOS and Apple frameworks may generate technical logs (for example, crash logs and performance diagnostics), and those logs may be transmitted to Apple when Apple analytics sharing is enabled on your device. We do not use third-party analytics, advertising, or tracking SDKs in our App.
We do not integrate third-party analytics, advertising, or tracking services in our code.
We may update this Privacy Policy from time to time. If we make changes, we will update the effective date at the top of this page. Your continued use of our App after an updated policy is posted means you accept the updated policy.
If you have any questions about this Privacy Policy, please use . See also our Imprint.
