sign in with bluesky
your atproto account
polls write to your pds, guests either sign in via atproto or stay anonymous, i don't know, i'm not a cop.
don't have an atproto account? make one on bluesky, or host your own at selfhosted.social. any account works here. you sign in with its handle.
on the next screen, letsmeet asks only to write its own poll and response records in your account, plus a calendar event when a time is picked. no posting, no reading your stuff, nothing towards other services.
