Altkata is a paid, single-purchase app. There is no business model that requires collecting your data, and the app is designed accordingly.
What stays on your device
Everything you do in Altkata — your review history, scheduling state, daily-limit settings, topic on/off toggles, any issue reports you file — is stored locally on your device using Apple's SwiftData framework.
If you sign in to iCloud and leave it enabled, that same data is synced to your own private CloudKit database, accessible only to you. The developer never sees it. No backend service reads it. iCloud sync is optional and can be turned off at any time; local-only is a first-class mode.
What we do not do
- No third-party analytics SDKs (no Firebase, no Mixpanel, no Amplitude, nothing).
- No third-party crash reporters (no Sentry, no Crashlytics).
- No advertising. No ad-tech identifiers. No IDFA.
- No accounts, no sign-ups, no email collection.
- No outbound network requests from the app itself. The app does not "phone home."
Crash and diagnostic reports
Altkata uses Apple's MetricKit framework. When your device occasionally sends Apple aggregated, anonymized crash and performance metrics (a system-wide setting you control under Settings → Privacy & Security → Analytics & Improvements), Apple makes those reports available to the developer through the Xcode Organizer. The reports contain no personal information and are not associated with you. If you have analytics sharing turned off in iOS, the developer receives nothing.
Reporting an issue
The in-app Report Issue screen opens a prefilled email to the developer in your own Mail app. You see exactly what it contains and choose whether to send it — nothing is sent unless you do. A report email includes the exercise's id, the issue type you pick, the app version and build, a timestamp, a random report id, and any notes you type. The report is also saved on your device and, if iCloud is on, synced to your private iCloud.
Privacy claim, in one sentence
This app sends no data anywhere except your own iCloud (when iCloud is available). If you use the in-app Report Issue screen, it opens a prefilled email you review and send yourself; nothing leaves your device unless you send it. Crash and diagnostic reports go through Apple's standard, anonymized channel and reach only the developer.
