For example, when you go to a website with a <b>Like</b> button, we need to know who you are in order to show you what your Facebook friends have liked on that site. The data we receive includes your user ID, the website you're visiting, the date and time and other browser-related info.If you’re logged out or don’t have a Facebook account and visit a website with the <b>Like</b> button or another social plugin, your browser sends us a more limited set of info. For example, because you’re not logged into Facebook, you’ll have fewer cookies than someone who's logged in. Like other sites on the Internet, we receive info about the web page you're visiting, the date and time and other browser-related info. We record this info to help us improve our products. As our Data Policy indicates, we use cookies to show you ads on and off Facebook. We may also use the info we receive when you visit a site with social plugins to help us show you more interesting and useful ads.

https://groups.google.com/forum/#!msg/tosdr/9Tm3gwYnlVE/s6l9fmMlzgoJ It is quite impressive how much information you can find in plain text
on facebook pages, if you know where to look. Maybe I should just map
the facebook maze^W website.

since the Like button is a little piece of Facebook embedded on
another website, the browser is sending information about the
request to load Facebook content on that page. We record some of
this information for a limited amount of time
TODO: what's that limited amount of time? (see below I assume)
when you go to a website with a Like button, we need to know who
you are […] The data we receive includes your user ID, the
website you're visiting, the date and time, and other
browser-related information.

If you’re logged out or don’t have a Facebook account and visit
a website with the Like button or another social plugin, […] We

"anonymized information"???? WTH. They have "browser-related
information" although they don't have the facebook user id. Is that
really anonymity? what's browser-related information? is a cookie
browser-related?

Fortunately the last part gives us some guarantee; but I'd be more
confident if they were in the terms rather than an help page…

we do not use the information we receive when you visit a site
with the “Like” button or another social plugin to create a
profile of your browsing behavior on third-party sites or to
show you ads, although we may use anonymous or aggregate data to
improve ads generally. We delete or anonymize the information we
receive within 90 days, and we don't sell it to advertisers or
share it without your permission.

Now. That's an interesting question: they say they "delete or anonymize"
which supposes that the information is previously not anonymous -- I
suppose that refers to information recorded on users logged-in.

So as I understand, that means that for information gathered on users
who are logged-in, Facebook keeps the information forever (except the
user-id). That information includes "the web page you're visiting, the
date and time, and other browser-related information".

TODO: facebook states they don't sell or share it unless they have "your
permission". I wonder where that permission comes from: is there a
privacy setting somewhere for this?
