Privacy policy

Last updated November 9, 2026

What we store

Your account (name, email, and a scrambled form of your password, or the ID Apple or Google gives us when you sign in with them), your logbook (the jumps you enter or scan), your wind limits and settings, and the days you mark as held for weather.

What we use it for

Only to run ARCH for you: show your logbook, score the weather against your limits, and learn which days you actually jump. We don't sell your data, show ads, or share it with advertisers.

Services we use

Weather comes from public sources (Open-Meteo, the US National Weather Service, and airport weather reports); we send them a drop zone's location, never anything about you. If you scan a logbook page, the photo is sent to Anthropic's AI service to read it and isn't kept by us afterwards. Sign in with Apple and Google are handled by Apple and Google.

Deleting your data

Settings → Your account → Delete account removes your account and every jump in it right away. You can export your logbook as a spreadsheet first.
