In the free version, this is technically impossible because WP builds up the admin menu dynamically instead of (for example) loading it from the database. So the plugin can only edit the menu on the fly, which only works while it’s active.
In the Pro version, some changes could persist after deactivation because the Pro version includes a role editor, and role capabilities are something that WP already stores in the database; the plugin just edits them. Enabling/disabling capabilities can change the visibility of some admin menu items.
Which version are you using, and what changes are still displaying? If it’s only includes things like certain menus being visible (or hidden), that could be related to role capabilities. If it’s something more than that, it could be that there’s actually another active plugin that’s applying those changes – try deactivating other plugins as a test.

It’s the paid version, so I’ll write to you on the site.
