How do I change which notifications I get?

In the app: Settings, then Notifications. On the web: Account, then Settings. Each toggle covers one topic:

• Orders — sales, shipping updates, refunds, disputes.
• Messages and offers — new messages, offers, counters, accepts.
• New drops — when a seller you follow lists something.
• Crane Credit — credit added to your account.

A toggle silences the push and the email for that topic. The notification itself still lands in your in-app inbox, and sign-in and verification emails always send.
