DNAmosaic is a tool that helps you estimate how you are related to your DNA matches. You can either simply get an estimate, or by submitting a 'proven' match, get an estimation and help the system provide more accurate estimations in the future.

Absolutely. No raw DNA or surnames are collected. All data is anonymized. Your information is never shared, sold, or used for any purpose other than improving estimations for the community.

All estimations are calculated to the registered user. To register we require First Name, Age Range (30's, 40's etc:) Sex, General population (eg: European) Community type (eg: Close Community) Optional: email

Nobody. Your data is fully private, anonymized, and stored only to improve estimations.

Data is stored indefinitely to continue improving estimates. Everything is anonymous and cannot identify you personally.

DNAmosaic was built by a retired hobby genealogist who wanted a simple way to make sense of his DNA matches. This is a non-commercial, community-friendly project.
