if you are trying to be snarky at least do the bare minimum research https://grapheneos.org/faq#default-connections

"By default, GrapheneOS only makes remote connections to GrapheneOS services and the network provided DNS resolvers. There aren't any analytics/telemetry in GrapheneOS. The only information revealed to the GrapheneOS servers are the generic device model (such as Pixel 7 Pro) and OS version which are necessary for obtaining updates. The default connections provide the OS and apps with updates, set the system clock, check each network connection for internet connectivity, download a global database (does not vary based on location) with predicted satellite locations when using Location and obtain attestation chain signing keys for the hardware keystore needed for the hardware-based attestation feature."
