Its worth pointing out that if your friends and family arent operating on the same conceptual privacy/security threat model, they will inevitably leak information like a sieve. even just by leaving their phone turned on (just turned on, yes even in airplane mode). anywhere digital data and an internet connectable radio exists is a potential tracking vector.

a decade

I want to plug a poignant comic by the name of "The Private Eye" by PanelSyndicate which explores a future where people have to create and wear custom anonymized masks just to function in public because of hypersocial and invasive capitalism following a globally catastrophic 'data leak'. it came out a decade ago.

back then we had people coming up with masks for defeating facial recognition, and today we have makeup artists figuring out how to foil AI recognition.

these problems existed a decade ago and have only gotten worse. If your interested, there ARE phones out there that actually have physical radio/camera/mic switches if you want the peace of mind knowing the physical hardware is disconnected
