Each license is meant for individual use and is not recommended for simultaneous use across multiple devices, as this may lead to syncing errors. However, you can easily switch between using Atticus on your desktop during the day and on your laptop in the evening or while traveling, as long as it's only active on one device at a time.
If you decide to share access with a co-author or team member, they will need to use your email and password to log in. It's important to coordinate schedules to avoid both working in Atticus simultaneously. Additionally, make sure to fully log out of Atticus using the profile icon in the top right before allowing another person to access the account.
I also encourage you to check out our Terms & Conditions, particularly section 5, to explain the licensing terms in more detail: https://www.atticus.io/terms-conditions/
