I have 26 apps on my phone. Of those, four are Safari extensions, one is a PWA and another I wrote myself. I use a restrictive nextDNS profile that also blocks Apple's native tracking (as best they can) and don't use social media. I feel like that's the best I can realistically do.
And you do realize your cellphone is constantly sharing your location with your cell phone company which is more than willing to give it to the government without a warrant.
Whatever you are doing is meaningless privacy theatre
I wouldn't call that meaningless privacy theater. For one, you can buy a SIM anonymously, and make the cell location data essentially useless. Second, protection at the DNS level prevents other types of data exfiltration (such as cross-site tracking by the Meta Pixel). By not using social media and communicating over secure apps like Signal, you can indeed achieve a high degree of resistance against tracking and profiling.
Of course, you can do more, such as running only trusted software (i.e., free software) on your devices, not using Internet-of-Shit devices anywhere in your home, and making sure your car is not snooping on you through it's own cellular modem.
> you can buy a SIM anonymously, and make the cell location data essentially useless
Even ignoring the first part, which will vary by country, I think that represents a failure of imagination.
For example, how many other people-with-phones have a pattern of spending 5+ nighttime hours within 100m of your home, and spending 5+ workday hours within 100m of your office?
