1. Overview

PunnettSquare Tools ("we", "our", or "the Service") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our free online genetics and biology calculators.

2. Information We DO NOT Collect

We want to be clear about what we do not collect:
