Roots Adventure tools are built to keep facts, interpretation, and hypotheses separate so your family story stays careful and defensible.
Calculator output and generated plans are leads to test, not proof of a family relationship.
When a tool cannot support certainty, it says so plainly and keeps competing possibilities visible.
Public tools avoid raw DNA uploads, unnecessary living-person details, and fake account storage.
