I don't have TOR or VPNs installed on my phone, however my router is picking up incoming TOR connections to the phone. It probably happens once a day and the logs show about 20 random connections to my GrapheneOS phone, port 53208, 54596, 34658, 35366 etc..etc.. they always seem to be random.
Is this a rogue app or does GrapheneOS use some sort of a TOR network for update checks or something?
