Am I loosing the theme settings if I deactivate it?

Hi Sakin, I have a purchased plugin (The Events Calendar PRO) which is making some menu points unaccessible in the dashboard view and I would like to deactivate the Catch Everest PRO theme and activate a native Wordpress theme in order to analyze if the plugin has any conflicts with the theme. If I do that, without deleting the theme (just deactivate it) will I loose the settings? After the check, can I just reactivate the plugin and everything to be as it was? Thank you in advance, Robert
