Privacy experts are giving 23andMe customers advice on how to handle their DNA results. The experts are warning that the company’s info on millions of people is up for sale. 23andMe, known for its saliva-based test kits that offer customers a look into their genetic ancestry, assures the security of customer data. But there's no guarantee about that because of their bankruptcy. That data includes information like genetic predispositions to health information. If you've stored your saliva sample and DNA with 23andMe and wish to change that preference, you can do so in your account settings under "Preferences." Customers had to deal with their info being hacked in 2023.
