We set no cookies. Not on this site, not on the API. No analytics cookies, no advertising cookies, no fingerprinting, no local storage of ours. The API authenticates with a bearer token you hold; the pages you are reading are static documents.
When paid checkout goes live, our payment processor, Stripe, sets a small number of its own cookies on checkout pages — typically __stripe_mid (about one year) and __stripe_sid (about thirty minutes) — used strictly for fraud prevention and payment security. These are strictly-necessary cookies for completing a purchase: they appear only on pages that include Stripe's payment code, and never on documentation or API surfaces. Stripe's cookie policy governs them.
Your browser can block or delete cookies at any time. Blocking Stripe's fraud-prevention cookies may prevent checkout from completing; nothing else on this site will notice, because nothing else exists to notice.
If we ever add a cookie of our own, this page will say so plainly before it happens, with what it does and how long it lives. Questions: contact@sanctumx.ai.
