Privacy
Keyword Scout was built with a simple rule: don't collect what you don't need.
Keyword Scout does not collect, store, or transmit any personal information — ever.
All data you create — saved keywords, tracked apps, ranking history — is stored on your device using Apple's SwiftData framework.
Keyword searches query Apple's public iTunes Search API solely to retrieve App Store data. No user identifiers are included in those requests.
No advertising frameworks, no crash reporting, no user profiling. Anonymous event counts (e.g. "a search happened") are sent via TelemetryDeck — no personal data, no identifiers. Purchases are handled entirely by Apple via StoreKit.
