One toggle in Settings → Privacy controls your profile and reading activity visibility:

  • On — Library members can view your profile and see your reading milestones in activity feeds
  • Off — Your profile is hidden and your reading milestones stay off the activity feed

When you turn it off, we’ll ask if you also want to hide past reading activity from other members’ feeds.

Users ages 13–17 default to hidden and can have a supervising parent or guardian who controls the visibility toggle. See Supervision for Minors.

Your profile is only visible to members of libraries you’ve joined. People outside your libraries cannot find you by searching.

We honor requests to export or delete your personal data. Contact support and we’ll send you a copy of your data or walk you through permanent deletion.

To close your account and delete your data yourself, see Deleting your account.

We use trusted third-party services for:

  • Email delivery — To send notifications
  • Book data — To look up book information when you add books
  • Image hosting — To store book covers and profile photos

These services only receive the minimum data needed for their function.

  • Encrypted connections — All data transmitted over HTTPS
  • Secure storage — Data stored with encryption at rest
  • No passwords — We use email/SMS verification, not passwords
  • Session management — Automatic logout after extended inactivity
