Privacy, for the waitlist.

What we collect on this page: the email address you type, the time you joined, the part of the page you joined from, your browser's name and the country it connected from. Nothing else — no analytics, no cookies, no third-party scripts besides the font.

What we do with it: send you one email when ARKN opens, and hear back from you if you reply. We do not sell it, share it, or use it for anything else.

Where it lives: in a Supabase database belonging to ARKN, written only by this site's server. It is not readable from the web.

Leaving: reply to any email from us with "remove", or write to support@arkn.app, and the row is deleted.

The app

The app's privacy policy is published with the app on the App Store. The short version, which the app is built around: your log lives on your iPhone first; sync exists for backup; Flow reads what you logged and nothing else; your data is not used to train models; you can delete everything from inside the app.
