Unfortunately this is a bigger problem than what information Apps are able to record from a person. Telco’s can see your location at all times while you’re connected to their network and depending on local laws they record this data and keep it stored for years at a time. This includes a full point to point map of all your movements at all times (going back even years).
In Australia a controversial law was passed years ago that enforced Telcos to retain custom metadata (including all customer location movements) for 24months for purposes of “crime prevention” and “anti-terrorism”.
And unfortunately until we lose our dependence on these companies by moving over to Starlink type networks or a (hopefully) future Apple equivalent, the only way to currently avoid this collection of all your movements throughout the world is to have your phone always on Airplane mode and only switch it on when you really need it.
With all the debate that happens here over App related privacy issues I really wish more people knew that literally all their movements are being recorded by their Telco providers and shared freely with Law Enforcement and Intel Agencies.
The benefit of the doubt can be given to data-thirsty apps who ultimately have a profit motive and ultimately don’t care who you are so long as they profit over your spending. But the Intel & Gov agencies however want nothing more than to know everywhere you go and everything you do, and this seldom discussed privacy flaw is a far greater risk to public safety and privacy than Instagram wanting to sell me targeting items.
