What Letnook does with your data
The book stays on your device and in your own iCloud. Letnook has no account, no server of ours and no analytics. The app never sends your book to a Letnook server because we do not run one.
On-device storage
The book is kept on your iPhone or iPad. Letnook does not send it to a Letnook server and does not ask you to create an account.
Your iCloud
iCloud keeps the book in your own Apple account. Pro's versioned backups use your iCloud Drive. Letnook does not host either one.
Documents and permissions
The camera and photo library are used only when you choose to photograph or attach a document to a spot. That document stays with your book on your device and in your iCloud.
Payments and collection
Letnook draws the payment code from the details you enter. It does not connect to a bank, move money or see a transaction. A forwarded slip is credited locally by its bank reference, with duplicate references rejected.
What we collect
Nothing is collected by Letnook. There is no account, advertising, tracking or analytics, and the app does not collect your name, a renter's name or the contents of your book.
