hrkltz ("we", "us", or "our"), as the provider of Astryn for iOS ("App") and astryn.hrkltz.io ("Website"), is committed to protecting your privacy. This Privacy Policy explains how we handle information for the App and Website.
Astryn 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.
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.
Astryn 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 Astryn.
We do not use cookies for analytics, advertising, or user tracking.
Like most websites, basic technical request information (such as IP address, user agent, requested URL, and timestamp) may be processed by the web server or hosting infrastructure for security, reliability, and operations.
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 Astryn after an updated policy is posted means you accept the updated policy.
