Privacy policy

What we do not collect

We do not ask for your name, email, phone number or identity documents. We do not use advertising cookies or third-party analytics scripts.

What is stored in your browser

• Session key: when you enable trading, a trading key is created and stored in your browser's local storage so you can trade without a wallet pop-up. It never leaves your device except as signatures on your trades.
• Preferences: for example, whether you have accepted the risk notice.

You can remove all of this at any time by clearing this site's data in your browser.

Third-party services your browser contacts

• Hyperliquid public API and HyperEVM RPC, for prices, charts and on-chain balances.
• Papertrade API, through our same-origin proxy at /api, for your balances and positions and to submit signed trades. The proxy forwards requests and does not store them.
• Your wallet provider, such as MetaMask or OKX Wallet, under its own privacy policy.

Your wallet address and on-chain activity are public on the blockchain by nature.

Server logs

Our hosting and network providers may keep standard technical logs, such as IP address, browser type and requested page, for security and operations. We do not combine these logs with wallet addresses.

Changes

We will update this page if our practices change. The date at the top shows the latest version.
