Question: all these permitions are allowed by default? Or the app asks for it and you can allow them or not from Android/iOS permissions, like notifications?
You can find the settings of what a certain app can access in Manage Apps in Settings. The permissions that each app has are listed there. You can revoke some of them, but some apps will just fail to start with all of them revoked.

You can block some things (like location data), but a lot of it is only moderated using an “Ask app not to track” button, which is more lenient.
I didn’t know there was a button like that! Where can I find it on Android?

I was talking about iOS, the image in the post is compiled from AppStore screenshots. Here’s a relevant page on Apple’s website.
As for Android, I’m not really sure. Probably by installing DuckDuckGo? It runs a local firewall-type thing that blocks known trackers.
