Spine privacy policy
Spine has no accounts of ours, no servers of ours, no advertising and no analytics. Your reading history stays on your devices and in your own iCloud.
What Spine keeps
- Your books: the books you added or imported by hand, your edits to any book's details, its copy (paper, ebook and so on), and the cover photos you pick.
- Your reading: each book's status and dates, earlier reads, the positions Spine has seen, pages you logged, and any quotes.
These sync between your iPhone, iPad and Mac through your private iCloud database. We never receive them.
Kept on each device only, and never synced:
- Spine's copy of your Readest library and your Readest reading time and pages per day. Each device downloads them from Readest itself.
- Downloaded covers, the Reading tab's layout and order, and a list of books with no cover found, so Spine waits a week before looking again.
Readest
If you sign in with your Readest account, your email and password go once to Readest's sign-in service. Spine keeps only the resulting sign-in token, in your device's Keychain, and never stores your password. With that token, Spine reads your books, reading positions, reading time and covers from Readest. It never writes to or changes your Readest library. What Readest does with your data is covered by Readest's own policy.
Finding books and covers
When you search for a book, scan a barcode or type an ISBN, what you entered is sent to open library catalogues: Open Library, Inventaire and the BnF catalogue. For a book with no cover, Spine may send its title, author or ISBN to Open Library to find one. If you import a Book Tracker export, Spine downloads the cover links saved in it. No other information about you goes with these requests.
What Spine never does
- No accounts of ours, no advertising identifiers, no analytics or crash reporting services.
- No sale or sharing of your data with anyone.
- No changes to your Readest library.
Deleting your data
Removing a book hides it in Spine and in your stats; your copy in Readest stays as it is. Sign Out in Settings deletes the Readest token and Spine's copy of your Readest library and reading time from that device; what you added yourself stays. Deleting Spine removes its data from that device. To remove the synced copy too, delete Spine's data from iCloud in the Settings app, under your name, iCloud, then Manage Storage.
