In Ulysses, you don't have a separate user account. Your subscription is linked to your Apple Account, while your content is synchronized through iCloud Drive.

Subscription access

To ensure that Ulysses recognizes your subscription, please make sure you’re signed in with the Apple Account you used to purchase it. Check this under (System) Settings › [your name] › Media & Purchases (› Manage). 

If Ulysses doesn’t recognize your subscription, please follow the steps in our FAQ article.

iCloud synchronization

To synchronize your content across devices, ensure that you’re signed in with the same Apple Account and that iCloud Drive is enabled on all your devices. Ulysses must also be allowed to use iCloud.

If you’re having trouble synchronizing your content, please follow all the steps in our iCloud synchronization FAQ to make sure that everything is set up correctly.
