If you think your information is safe with ANY company then you haven't been reading the news lately. It really doesn't matter if a company SAYS your data is safe with them. At some point they'll get "hacked" and your personal information will be set free to the world (or, at least, to the underworld). Depending how good their sob story is, they may get a slap on the wrist from the EU. And here in America, nothing will happen because our government couldn't care less about keeping our personal information secure.
That's sadly true. Protection of one's personal information is more so an illusion rather than a reality. Can we really say it wasn't like this in the past? It's issues like this that tend to drive me away from wanting to use online services. Unfortunately, we're just too dependant upon them in this day and age. It's why I'd rather not have everything linked up together.
All you can ever do is go on and hope your details are never leaked or snatched.
