Opt Outing: Online Data Collection Services

MacRumors administrator, Doctor Q, has done some research in finding opt out links to get off of certain mailing and calling lists. I think its great information to have and can be difficult to find at times. Therefore, I am re-posting it here for the benefit of all.

Doctor Q:

I routine opt-out of mailing lists, cookie trackers, mobile phone trackers, and other collection systems would otherwise track me without my permission. But I don’t click on any old opt-out link since unscrupulous people could collect personal information that way. The services I opt out from are the ones I know to be legitimate tracking services that collect information and sell it to other businesses.

Here are three of them. Since these services are pervasive but obscure I thought I’d share the links I uncovered with you. If you know more real tracking businesses from which we can opt out, you’re welcome to share the links.

Euclid Analytics

They track your phone’s wi-fi information when you go into certain retail stores.

To opt out you go to this page and enter your phone’s MAC address (Settings -> General -> About -> Wi-Fi Address on your iPhone).

If you use a cookie manager, you need to mark any opt-out cookies as “permanent” or “whitelisted”.

There was a recent Security Now episode (Security Now 404: How Facebook Monetizes) where Steve Gibson spoke about those companies as well. He detailed how they work and ways to opt-out.
