Hey Gerardo

Thanks for posting in the Lucid Community! We currently do not have a way to disable auto-save so I apologize for any inconvenience this may cause. If this is something you would like to see in Lucidchart please fill out this Feature Request form to let our Product Managers know!

If you have a Team or Enterprise account you can access the Revision History feature which allows you to view the change history of a document and revert a document to a previous version. Please review this Help Center article about Revision History in Lucidchart to learn more about how to utilize this feature.
