Please don’t send sensitive personal information (passwords, bank details, government IDs) over email. For account-recovery questions, use the Forgot Password or Lost Authenticator flows directly — they don’t require email back-and-forth and they’re more secure.
During the beta program, the fastest path to a real human is the in-app feedback widget — the small floating button on every page. Anything you submit there lands in our triage queue and is reviewed by one of the founders within the same day. The email addresses above are for things that don’t fit the in-app workflow.
