Crabwise is built to work entirely offline. This policy explains, plainly, what that means.
Crabwise does not collect, transmit, or share any personal data. There is no account, no analytics, no advertising, and no network calls of any kind — the app has no code path that sends anything to a server, because it doesn't have a server.
Everything you type — your units, your saved aircraft, your leg plans, your calculation history if you use it — is stored locally on your device only, using standard on-device storage. Nothing leaves your phone. Uninstalling the app deletes it.
Crabwise shows no advertising and uses no advertising identifier, no tracking SDK, and no third-party analytics library of any kind.
Crabwise Pro is a one-time, non-consumable purchase handled entirely by the App Store or Google Play. Crabwise never sees or stores your payment details — that is between you and the store you bought it from.
Crabwise is rated for general audiences and collects no data from anyone, including children.
If this policy ever changes, the new version will be posted at this same address with an updated date above.
