[Placeholder: account profile (name, email, timezone, stated interests), the full text of letters you send and receive, billing information handled by our payment processor, and basic operational data like sign-in timestamps and IP address at signup.]

2. How we use it

[Placeholder: to generate persona replies, operate your subscription, and improve the service. We do not sell your correspondence.]

5. Your rights
