Do I need to log in to a tolino bookseller in the tolino app? You can use the tolino app without logging in, of course. However, in order to use all of the features of the app, you will need to log in to your tolino alliance bookseller account. You can only access your own personal storage in the tolino cloud once you have logged in to your bookseller. Only then can we make your content available online, automatically save your reading progress and synchronize your tolino eReader. Give it a try! You can log out at any time and continue to use the tolino app for eBooks and audiobooks without being logged in. Purchased books or audiobooks are always stored safely and free of charge in the tolino cloud. This means you can access your books and audiobooks at any time from multiple eReaders, including your smartphone, your tablet and your computer.
