Most (or all?) organizations that provide apps create profiles. A profile contains all kind of data on YOU. The things you view, the things you search and the things you do.
Many organizations collaborate with or have interfaces with other organizations. E.g. links to Dropbox or Gmail. And they share your profiles. Sharing your data partly or all of them.
Of course this is backed by the terms and conditions. But how do you know where your profiles are saved? Or worse: used?
In ManageMyMind we don’t do profiling. We create no profiles and we don’t use them. We don’t collaborate with other organizations. We only know your e-mail address an your name. We don’t pass them to anyone. And all other data belonged to, belongs to and will belong to you!
