IO does not use cookies, localStorage, IndexedDB, or any client-side storage mechanism. A page refresh is a complete wipe — there is no session to restore, no preference to persist, and no tracking identifier to recover. This is by design.
The entire IO architecture is built on the principle that nothing about a request is written down — on the server or on the client. Cookies are retention. We eliminate them. Sessions are purely ephemeral, identified only by an in-memory reference that disappears when the tab closes or the self-destruct timer fires.
Our hosting infrastructure (Cloudflare) may set strictly necessary technical cookies for DDoS protection and load balancing. These are not used for tracking or analytics. We have configured Cloudflare to strip all identifying headers before requests reach our inference servers.
Since we set no cookies, there is nothing to opt into or out of. Your browser's default privacy settings are fully respected. If you use browser extensions that block cookies, IO will function identically — because there are none to block.
