Privacy
New technologies are radically advancing our freedoms, but they are also enabling unparalleled invasions of privacy.
Your cell phone helps you keep in touch with friends and families, but it also makes it easier for the feds to track your location.
Your Web searches about sensitive medical information might seem secret, known only to you and search engines like Google. But by logging your online activities, these companies are creating a honeypot of personal information, potentially available to any party wielding a subpoena.
And the next time you try to board a plane, watch out—you might be turned away after being mistakenly placed on a government watch list based on erroneous data.
Technology isn't the real problem, though; rather, the law has yet to catch up to our evolving expectations of and need for privacy. In fact, new government initiatives and laws have severely undermined our rights in recent years.
Privacy rights are enshrined in our Constitution for a reason — a thriving democracy requires respect for individuals' autonomy as well as anonymous speech and association. These rights must be balanced against legitimate concerns like law enforcement, but checks must be put in place to prevent abuse of government powers.
EFF fights in the courts and Congress to extend your privacy rights into the digital world, and supports the development of privacy-protecting technologies. Donate to EFF to help support our efforts.

- Locational PrivacyEFF is fighting to protect the privacy of this data that users of phones, GPS transmitters and location-based services leak to providers and to the government.
