2. What the site stores in your browser
These aren’t cookies and are never sent to us automatically. They stay on your device:
- IndexedDB “arbtrader”: exchange keys you connect (stored as non-extractable keys), your Polymarket wallet address, and your order-ticket log. Remove them from the Connections tab or by clearing this site’s data.
- Local storage: that you’ve seen the cookie notice, so it isn’t shown again; and, if you opened a friend’s referral link, their referral code, kept for up to 60 days so your discount applies when you sign up.
- Session storage: one-time messages between pages (for example after signing up); cleared when you close the tab.
3. Third parties
Our pages load fonts from Google Fonts, which sets no cookies. The homepage’s explainer videos show thumbnail images from YouTube’s image server; the video itself loads only when you press play, and a video you play comes from YouTube’s privacy-enhanced mode (youtube-nocookie.com), which YouTube says doesn’t use your viewing to personalise your YouTube experience, but it may still store data in your browser under Google’s cookie policy. When you go to checkout or the billing portal you’re on Stripe’s site, and Stripe uses its own cookies for payment security and fraud prevention under Stripe’s cookie policy.
4. Your choices
You can block or delete cookies in your browser settings. If you block the session cookie you won’t be able to log in; the public pages and the demo still work.
Switch off the source cookie. Switch it off in this browser: it’s replaced with a note that says “off”, kept for a year, so it isn’t set again. Turning on Global Privacy Control or Do Not Track in your browser does the same everywhere. Logging in or out doesn’t change it.
