Am very impressed with my Android Desire but leery about what the various apps are doing with my data. In circumstances like this I fall back on encryption so if someone burgles my computer (or smartphone) and steals sensitive files they just get gibberish. An encryption app should be from a person or company with a verifiable name and mailing address or some kind of reputation which inspires confidence. Alternatively, it should be written in Open Source code that allows one to check whether it it kosher. Otherwise it may contain "back doors" which allow the author to access one's data. Is there an Android app that fulfils these criteria ?
