Email last.pass.oda@gmail.com with your question. Include your username and, if you are reporting a problem, what you were doing when it happened. We usually reply within a few days.
If you registered an email address for recovery, choose "Sign in with email" on the sign-in screen and enter the code we email you. After signing in, add a passkey on your new device from the same screen. Without a registered email address there is no way to recover the account — this is a consequence of storing only your passkey's public key.
That is a Simulator limitation (no iCloud Keychain), not a bug in the app. Use a real device.
Settings > Delete account. This removes your profile, your videos (including the copies stored for playback), your passkeys, your username and your room memberships. It cannot be undone.
Only the members of the room you posted to, and only for 24 hours. After that the video moves to an archive that only you can see.
To report a video or a member, email last.pass.oda@gmail.com with the room name and what you saw. Room owners can also remove members from their own rooms.
