We store your email, verification time and optional update preference to provide library access. Verification does not require marketing consent. We do not enroll you in Substack automatically.
Access links expire after 15 minutes; sessions after seven days. Abuse-limit records expire after 24 hours and are cleaned on the next signup request. Change email preferences or delete your account from the library. Encrypted daily backups retain deleted data for up to 30 days.
