Is it legal to just send data to bStats?

I put a Minecraft plugin on the internet.

Now I would be interested in some data (How many percent use which Mc Version / Java Version / Plugin Version / Server software use)

Is it okay with data protection if I simply send the data to bStats.org?

It looks like it is not sent which server is which now.

In any case, I can't see anything about it there.

You can of course switch off the sending of the data in the plugin.

So? Can I simply integrate this into my plugin and be fine?

Or do I have to do some stuff for that? (Then I'd rather leave it).

I just know that many plugins do this. And in itself that's not a problem because none of this is personal. But what that looks like under German law… I don't know.

Many well-known plugins use all the functions of the bStats, so I think if it were illegal then that would already be known.
