The American Civil Liberties Union just released documents detailing the different kinds of private information wireless carriers are storing about your cell phone usage habits.The data came from the Department Of Justice in August 2010, but was just made public today by the ACLU, the National Journal reports.

Among the most important pieces of data the documents provide is that cell phone carriers know which cell towers you’re using, then hold on to this information for up to two years.

This information could be used to find out where you’re using your phone the most, and where you’ve been. The report was originally generated by the DOJ to aid federal agents trying to uncover a person’s calling history.

Also, did you know that Verizon holds on to your text message content for 3-5 days after you send a message? Virgin remembers your texts for three months. AT&T, Sprint, and T-Mobile, on the other hand, don’t keep track of your texts at all.

For the full report, check out the ACLU’s website, and see a screenshot below of the data chart:
