In my professional environment I often have to use Windows.
To get a minimum level of privacy, improve my workflow and have my config everywhere I want to use portable apps. My question is how can I trust the portable apps providers?
For example portable apps is a well known portable apps provider but as far as I know they don't release the sources of their apps. So how can I be sure that their apps are exactly the same as the original ones and that they don't add a tracker or something like that along with the portability?
I know that the framakey project is a known, open and trusted french project providing portable apps but for example they do not provide an original Firefox but a 'Framafox' custom version which is not what I want.
Is the only way to get a trusted portable app to source it by myself?
