Privacy

Auspex is a thin client over Polymarket. We were built with the assumption that we should hold as little of your data as possible — ideally none. This page explains where the lines actually fall.

What we don't collect

• No email addresses, no passwords, no accounts.The site has no signup form. Connecting a wallet via Privy doesn't create an account in any Auspex database.
• No KYC, no off-chain identity.Polymarket itself may enforce its own restrictions; we don't add any.
• No private keys, no signing keys, no recovery phrases. Every order is signed in your wallet and sent directly to the Polymarket CLOB.

What lives in your browser

• Your starred markets and saved filter views are stored in localStorage. They survive page reloads and follow your browser; they aren't synced to our servers.
• Your followed wallets list (other traders you want to track) lives in localStorage.
• Your notification preferences (whether browser push is enabled) and your activity inbox live in localStorage.
• Clearing your site data wipes all of the above. There's no server copy to recover.

What our servers see

• Anonymous request logs.Vercel records IP + URL for the standard reasons (rate limiting, debugging). We don't attach those logs to wallet addresses, and we don't share them.
• Aggregate analytics. We use Plausible (no cookies, no fingerprinting, no individual tracking) to count page views per route. The dashboard is public.
• Our /api/marketssnapshot endpoint is queried by everyone on the screener; we don't log individual queries beyond the standard Vercel access log.

Third parties

Loading the app makes requests to these services, which have their own privacy policies:

• Polymarket (data-api, CLOB) — markets, prices, your fills.
• Privy — wallet connect flow.
• Across Protocol — USDC bridging quotes (only when you open the Bridge dialog).
• Etherscan / Polygonscan — proxy address lookups.

Changes

If we ever change how we handle data, we'll bump the date at the top of this page and note it in the changelog.
