Cairn Privacy
Cairn has no accounts and collects nothing that identifies you.
Your logs
Parks, states, dates, notes, ratings, and photos stay on your device. If you are signed into iCloud they sync through your private iCloud database, which only you can access. We run no servers and cannot see your data.
Analytics
Cairn sends anonymous usage signals through TelemetryDeck, a privacy first analytics service that never receives your identity, your location, or the contents of your logs. Signals cover things like how many people complete onboarding. TelemetryDeck's own policy: telemetrydeck.com/privacy.
Purchases
If Cairn ever offers an optional upgrade, purchases run through Apple and RevenueCat with an anonymous identifier. No purchase is required to use the app.
