Nethunter OpSec

[Nyrid]

Hello there,

I am user of Linux ( debian 11 ) on my local computer but I get phone ( Samsung A40 ) which I was flash ( TWRP ) and root after that I was install custom rom ( crDroidAndroid-11.0 ) without gapps and google,after that I download Nethunter ( apk ) and chroot ( full ) and make success installation so....

Now i have Nethunter almost full working Linux ( only main problem I have with aarch64 because most app works with arm64 and etc )
now i am paranoid about Google

because Google was developed android and custom rom what I use can be ( i think ) controlled or checking with Google
so my question is about OpSec ( i use VPN + TOR ) ( mac adress set to random )

i wanted rom like CalyxOS,GrapheneOS and etc secures,privacy rom but unlucky for me ( Samsung A40 ) is not supported
also I want ask about its possible to see ( IMEI,SERIAL NUMBER ) when i browse ? because i think only mac,canvas,webRTC,dns and etc

thats all what I want know for now so promise my bad English language
also I am not experienced like You guys and I learn something new every day

"IMEI, SERIAL NUMBER" aew not collected through a regular web-browsing nor a mac address is visibl. The mac address is visible only in LAN, the IMEI is transmitted through GSM communication.
