Privacy Policy
Last updated: June 10, 2026
This policy covers both the iOS app and the website at audonia.app. Audonia has no accounts and no sign-in. The two surfaces handle data differently, so they are described separately below.
The iOS app
The app collects no personal data. It links no third-party analytics or advertising SDKs, and nothing that identifies you leaves your device. Crash diagnostics, when iOS provides them, are stored only on your device. Exercises are generated entirely on your device, so using the app sends nothing to our servers. The one exception is when you choose to send a bug report or feedback: that submits the message you write, and any details you add, so we can respond. The app sends no account, device, or tracking identifier.
The website
The website uses PostHog for privacy-conscious, aggregate usage analytics (which pages and exercises are used), configured for aggregate usage only, not cross-site tracking or advertising. To count unique daily visitors without storing identities, the backend derives a visitor identifier from a daily-rotating hash of your IP address and user agent. The salt rotates every day and is never stored, so the identifier cannot be linked back to you or carried across days.
When you send feedback
If you send feedback or report a bug (on the web or in the app), we collect only what you choose to send: your message, an optional email address (used solely to reply), an optional screenshot, which can include whatever is on your screen at the time, and basic diagnostic details about the exercise and your app or device so we can reproduce the issue. It is entirely voluntary, used only to respond and fix problems, and never for advertising. We do not sell them or share them with third parties.
What Audonia never does
Your data is never sold and never shared with third parties for advertising. There is no profile, no cross-site tracking, and no account to delete.
