What's Wolfram's policy about personal data usage? (And is it better or worse than Facebook?)
Come back again! Fresh data = new results every time!
Your information is only stored for one hour, so each time you return, we'll run fresh analytics on your Facebook data.
While they say they do not sell, rent, or lease your information to third parties they do not say they delete it. So if you let them get your facebook data, they will have and keep it.
No-go for me. This is a perfect example of why I prefer applications that run "locally" on my computer. There seems to be nothing in this report that would not be possible to do with a combination of open-source solutions.
Wolfram (the person, and by extension the company) really seems to have gotten very interested in personal metrics in the last few years.
