Also, why must all the services attempt to guilt me into turning it back on?
Disc: Googler.
Enable it, then set home and work. Then disable it.
So this is not your GPS data but most likely IP based city/metro.
Also it says "may" everywhere. AFAIK DDG may be doing all of those things too.
From a technical POV this looks such a huge FUD that it's sad.
Except that DDG explicitly says they are not:
When you access DuckDuckGo (or any Web site), your Web browser automatically sends information about your computer, e.g. your User agent and IP address.
Because this information could be used to link you to your searches, we do not log (store) it at all. This is a very unusual practice, but we feel it is an important step to protect your privacy.
If they don't store IP addresses then (I believe) they can't use wifi-router-based methods to find your location. Your browser also doesn't get a popup asking to give ddg your location.
So yeah I stand by my link and my interpretation of it.
At this point, I think mine is more of a nihilism towards this as I cut everything at the only reliable level: the network. But even then, I've hammered myself way too much over privacy, and it didn't make me any happier, since, at the end of the day, if anyone wants to track you, they'll track you.
