What is a Legacy Fallback License?
A Legacy Fallback License allows you to keep offline features when you cancel your subscription after 24 consecutive months. Instead of falling back to a free or previous version* of Logos, you'll keep features from your subscription tier that don't rely on the cloud or AI.
Who is eligible for the Legacy Fallback License?
If you’ve ever purchased a Logos 10 or earlier base package, you are eligible to earn the Legacy Fallback License after subscribing for 24 consecutive months.
