“People who are upset that Facebook is storing all their information should be really concerned that their cell phone is tracking them everywhere they’ve been… The government has this information because it wants to engage in surveillance,” an ACLU staff attorney said.
A newly released Justice Department internal memo reveals the retention policies of Verizon, T-Mobile, AT&T, and Sprint.
Verizon seems the most privacy-friendly, but is the only company that retains text message content. Messages are stored for 5 days; other companies don’t retain message content at all.
The retention of “cell-site data” (information of a phone’s movement history based on phone tower usage) varied the most among the four providers.
“Verizon keeps that data on a one-year rolling basis; T-Mobile for ‘a year or more;’ Sprint up to two years, and AT&T indefinitely, from July 2008,” reports Gizmodo.
Senator Patrick Leahy proposed to alter the Electronic Privacy Communications Act to “protect Americans from warrantless intrusions.”
