Subscription and billing

Crux subscriptions are billed by Apple, through your Apple Account. We never see your card and can’t change a charge ourselves.

Signing in

Sign-in links expire after 15 minutes and work once — always open the most recent email. If you signed up with one method (email, Apple, Google, or X), use that same method to get back to the same account.

Delete your account

Settings → Account → Delete account. This removes your account and the conditions and watchlists in it. Deleting your account does not cancel an Apple subscription — cancel that first, using the steps above. If you can’t reach the app, email hello@usecrux.io from your account’s address and we’ll do it for you.

What Crux is not

Crux watches the conditions you describe and tells you when they happen. It does not give investment advice, hold funds, or place trades. Data comes from third-party sources and can be delayed or revised; see the Terms for detail, and the Privacy notice for how we handle your data.
