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.
Privacy claim, in one sentence
This app sends no data to anyone except your own iCloud (when iCloud is available). Crash and diagnostic reports go through Apple's standard, anonymized channel and reach only the developer.
