Is web.tweetdeck.com Safe?

This is a wonderful Web Based Twitter Client, that is owned by Twitter themselves, so I would put "Trustworthiness" and "Vendor Reliability" at high. It provides (almost) real-time updating, has wonderful features such as Tweet Translation through Bing (Not all the time accurate,) automatic URL shortening (Only through ***** and Twitter's default t.co,) themes (You can only switch between a "dark," Mostly back and white theme, and a "Light" mostly white and black theme,) and the ability to change font and column size. It also features filters, which are good for child safety, but for some reason, if someone else retweets a tweet by a user you have filtered out, the tweet will still show up. I have not had this problem, however, when I filter out a hashtag. So, I would put "Child Safety" at "Good." Abine's (A trusted privacy company) Firefox plugin titled "Do Not Track Me (DNT)" shows that web.tweetdeck.com has "Google Analytics" embedded into the page, so I would also put "Privacy" at the lower end of "Good."
