It’s something we can test for ourselves really. But with giving your genetic information to a relatively unknown third-party, that’s something else IMHO…
Let’s not get too paranoid about this. After all we all have at some stage given our blood, urine and saliva samples to health clinics/hospitals. If the government or insurance companies or whoever wants to store your DNA samples ala X-files they would have done so already.
Ofcourse they are not telling us, but a company hell bent on misusing your DNA information will try to get it through other sneaky methods rather than advertising on their website about it.
If the insurance companies, government or whoever else did it in a sneaky way it would be in violation of the laws, at least in europe..
