Four51 Privacy Policy

Four51 is an independently developed app. It has no accounts, no analytics, no ads, and no tracking.

Everything you log in Four51 (your books, quotes, reading progress, goals, and achievements) is stored on your device and in your personal, private iCloud database so it can sync between your devices. The developer cannot see, access, or share any of it. Deleting the app and its iCloud data removes it entirely.

When you search for a book, your search text is sent to Google Books and Open Library to fetch results. These requests are not linked to your identity by Four51 and are not stored by Four51. Book covers are fetched from those services' image servers.

Notifications and widgets are generated on your device.
