We're here to put your mind at ease: Overwolf itself and any of its official apps will NOT get you banned.
We are working closely with game publishers to ensure that all the apps we publish are aligned with their Terms of Service and their 3rd party policies. We recommend that you make sure at all times that you are using an Overwolf app by downloading it directly from our appstore available at https://www.overwolf.com/appstore
