Answer 1

There are special services for analytics that provide a ready-made server with an API, and, importantly, they provide the power of this server, analytics is a rather "heavy" task. But you can create your own server, even on free hosting with PHP & MySQL.

Answer 2

I will add that a conscientious developer must necessarily mention in the license agreement the fact of automatic collection of statistics. It is advisable to describe in detail the composition of the information transmitted to your server automatically (without the participation of the user), and determine the scope in which this information can be used by you, that is, voluntarily limit yourself from the misuse of this information (release to public, sale to third-party marketers, extradition to all sorts of febeers without a court decision).
And an even more conscientious developer will add an option that allows you to completely disable the sending of statistics. Even if this option is used by a few, but its very presence shows your respect for ordinary users.
