Your privacy is closely protected on MyHeritage. We have made significant investments to ensure your account and personal details are secured and protected by multiple layers of encryption.
DNA data and DNA Matches privacy settings can only be controlled by the person who uploaded in the past DNA data to MyHeritage or the person managing a MyHeritage DNA kit, who’s the person who activated the kit.
You can check the DNA Matching privacy settings for your profile by following these steps:
1. Log in to MyHeritage.
2. Click on your name in the upper-right corner of the screen and select “My Privacy”.
3. Under “DNA preferences” you will see the privacy options available for your DNA results.
By default, users who get DNA matches can view the profile details of the matching people in the family tree. As a site webmaster, you can decide whether you would like to restrict other users who get DNA matches with your family tree from viewing the profile details of the living people in your tree for whom we found DNA matches.
To do so, please uncheck the "Allow DNA Matches to view profile details of individuals whose DNA data I have uploaded":
