With your permission, we use Google Analytics and Google Ads measurement for this public site. If you arrive from a Meta (Facebook or Instagram) ad, we also keep that ad's click ID for up to 90 days. If you later start a paid plan, our servers send Meta one count-only “paid signup” event with that click ID, the address of our billing page, and the browser type (user agent) your device reported when you started checkout, which we keep only until the event is sent. Nothing is sent to Meta from your browser, and Meta never receives names, email, IP address, payment details, amounts, answers, or form text. Withdrawing deletes the stored click ID and browser type and cancels any event not yet sent; Meta cannot be asked to recall an event it has already accepted. Privacy details.
