Why is it that the more we come to depend on our mobile phones as our lifeline to the the world, the more willingly we give up privacy and control?

Earthmouse: Mobile Guardian (E:MG) aims to change that by providing regular people with the tools they need to protect their privacy, anonymity and communications with friends, family and colleagues.

Built on the Google Android OS, E:MG will provide both applications and a completely new secure distribution that will run on low cost mobile phone hardware available throughout the world.

We are looking for users, developers, causes and partner organizations to contribute to, inform and guide our work.
