There is no waiting period. Account deletion in Langfuse is a hard delete: the userAccount.delete mutation in web/src/server/api/routers/userAccount.ts runs tx.user.delete({ where: { id: userId } }) inside a serializable transaction and the related rows are removed by cascade. Nothing keeps a tombstone for the email, so it is free for a new sign-up as soon as the delete request returns.

Also worth knowing for the "wrong region" case: the Langfuse Cloud regions (EU cloud.langfuse.com, US us.cloud.langfuse.com, JP jp.cloud.langfuse.com, HIPAA hipaa.cloud.langfuse.com) are completely separate deployments with separate databases and user tables. The data-regions page says you can have accounts in each region, so you never needed to delete the account in the first region to sign up in the right one.

If the sign-up form still tells you the email is taken, double-check the URL bar: you are most likely on the same region you deleted from and the browser session is stale, or the address is linked to an SSO login. Signing out fully and signing up on the intended region URL should work.
