Privacy Controls

Show Profile

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.

Minors

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

Profile Scope

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

Your Account Data

View and update

You can view and change most account information in Settings (profile, privacy, and notification preferences).

Delete your account

You can permanently delete your account in the app. See Deleting your account for requirements and steps.

If you cannot complete deletion (for example, blocked by active loans), contact support for help finishing the process.

Library data export

Library owners on eligible subscription plans can export library books, loans, and member lists (CSV) from Library Settings → Advanced. This is library operational data, not a personal account export.

Other privacy requests

For rights under applicable privacy laws (such as access requests where required), see our Privacy Policy and contact us using the instructions there.

Third-Party Services

We use trusted third-party services for:

Email and SMS delivery — Authentication codes and notifications
Book data — To look up book information when you add books
Image hosting — To store book covers and profile photos
Error monitoring — To diagnose crashes and performance issues

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

Security

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
