Privacy

BioPaternal answers your question without ever keeping your biological data. Here is exactly what is processed — and what is not.

No blood group kept

The blood groups you enter are analysed in memory, for the duration of the computation only. They are never saved to a database nor logged. Once the result is shown, they remain nowhere.

Anonymous statistics only

Each analysis only increments global, aggregated counters (total number of tests, exclusions, compatibilities, and exclusions per ABO / Rhesus / Kell system). These counters contain no personal data and cannot be linked to a person or to a specific test.

Account data

Sign-in relies on Supabase Auth (email / password or Google). Only the information required for authentication is kept. Access is protected by row-level security policies (RLS).

Value of the result

The report is strictly informational. It can exclude paternity with biological certainty, but can never prove it. Only a DNA test in an accredited laboratory has legal value.

Your rights

You can delete your account at any time. As no test data is attached to it, no information about you remains afterwards, apart from the already aggregated anonymous counters.
