Cookies This portal sets a single, strictly necessary session cookie to keep you signed in. It is first-party, cannot be read by page scripts (HttpOnly), and is not used for advertising, analytics, or cross-site tracking. Because it is essential to providing the service, it does not require opt-in consent. What we record For security and auditing we log authentication events — successful and failed sign-ins — including the account involved, the date and time, and the IP address the request came from. We also record administrative actions and calculator submissions. This forms an internal audit trail. How it is used This information is used solely to operate and secure the portal: to authenticate users, prevent abuse, and maintain an audit trail. We do not sell it, and we do not share it with third parties for marketing. Who can access the portal Access is restricted to authorized Valley Contax staff and licensed partner-lab users, governed by your account and your lab's license agreement.
