Delete your account
Deleting removes your account and everything attached to it: every topic you saved, every answer generated for them, their sources and version history, and the events recorded about your use of the app. It cannot be undone and there is no backup to restore from.
In the app
Open Settings and choose Delete my account and data. It takes effect immediately.
By email
Write from the address you signed up with and ask for deletion. You will get confirmation once it is done, within 30 days.
What is kept
Nothing that identifies you. Aggregate counts that carry no account, no email and no topic text may remain in operational logs.
