Your Privacy Choices
Ad measurement
When you purchase, we share a limited confirmation — a scrambled (hashed) version of your email and the order amount — with our advertising partners (Meta, TikTok) so we can tell whether our ads work. We never share your practice activity, scores, or study data.
We also honor the Global Privacy Control (GPC) browser signal as an opt-out.
