It has to do with new EU privacy permissions. I am not 100% certain of everything that has changed - because I don't live in the EU - but I know I had to approve a new privacy statement for our Google ads.
Nothing has changed with the site. As before, I do not ask for any personal information aside from a registration email. You may decide to share your name - or not - it does not matter to me.
The permission to link devices is a new one... I'm not sure what it means except that if you log in with the same credentials on different devices the two devices will show the same updated status(?)
And precise location is also new. I can never really know your precise location - I can just know the IP address that you post from, if I so care to look up that information. Most people post from numerous IP addresses - depending upon where they are and what device they use to log into the site. For example if I happen to be traveling in Europe and visit the site as I travel, I can post from over a dozen IP addresses that week. The only time IP addresses really come into play is with spammers - when I get a red flag for a new registration, for example, and they are trying to register from a known spam server in Russia... I can block the registration. But in terms of knowing something like where you live (exactly) your street address, etc - no I do not and can not know that.
FWIW I just looked at your account and you have posted to the site from literally hundreds of IP addresses - which should be no surprise for anyone with a cell phone, where each time you turn on the cell phone, or move to a different area you get a new IP address. Aside from knowing that you post a lot from numerous locations in the Netherlands... I can't tell much more than that. And you could have told me as much
To be honest, so much of this privacy stuff is for companies who are constantly seeking to monetize personal information. I am not in that business.
