Online privacy is not about having something to hide. It is about who holds a record of your behaviour, how precisely you can be identified without cookies, and which of those things you can practically change.
You cannot delete yourself from the internet, and anyone promising that is selling something. What you can do is remove the highest-risk material, cut the supply, and keep it down - which is most of the benefit for a few hours of work.
Most location tracking is not one setting but four - the app permission, the precision, the advertising identifier, and the history your phone keeps. Turning off the first only does part of the job.
The old warning was that anyone on the cafe network could read your traffic. Encryption largely ended that, and the FTC now says connecting through public Wi-Fi is usually safe. The risks that remain are different ones, and worth knowing precisely.
Most advice here is about companies watching you. This is about the other half - what you hand over yourself, what each piece is worth to a criminal, and the small number of habits that cut off most of it.
A movement history contains no messages or photos, and it still reveals where you live, work, and who you spend nights with. Here is what is actually collecting your location - apps, ad code, photo metadata, Wi-Fi scanning - and how confident you can be that it is really private.
