MirrorMeister / Support / Mac
I receive notifications about Screen Recording. Is MirrorMeister recording my screen or sending my information to a server?
No, we do not record your screen! We also do not send any content to a server. MirrorMeister only temporarily store data in the memory of your device before it is streamed to the TV. Upon streaming, the content is removed from memory.
