Your data belongs to you. It is not syd™’s to sell. Your data will only make it into the hands of third parties if you put it there yourself.
Website and services usage statistics and overall DNA test results – all generic, anonymised, and aggregated information – are used to help improve the services syd™ provides and assist with research into new products and services or general research in collaboration with a research entity (e.g. a university or research institute).
No information that could identify you individually is ever used in this way.
