Effective date: August 12, 2026

We do not use advertising cookies, third-party trackers, or cross-site profiling of any kind. Everything below is first-party and exists only to make the site work or to credit someone who referred you.

Your choices

Strictly necessary items cannot be turned off — without them you can't sign in, take an assessment, or pay. Optional referral attribution can be declined from the banner shown on your first visit, and you can change your mind at any time by clearing this site's data in your browser settings.

Do Not Track

We do not track visitors across third-party websites, so we have nothing to stop when a Do Not Track signal is sent. If your browser sends one, we honor it by continuing not to perform cross-site tracking.
