Privacy

• Your account. An account id from Privy, your email address if you sign in with email or Google, and when you last used Melyon.
• Your wallet addresses. The Robinhood Chain and Hyperliquid addresses linked to your account, so Melyon can show balances and place your trades. Addresses are public on-chain anyway.
• Your strategies and runs. The ideas and rules you write, any pictures you add to an idea, the amounts you start them with, and every check, order, fill and position, so you can see what happened and why.
• Who you copy. The wallets, Hyperliquid accounts and X accounts you choose to follow in a strategy.
• Telegram, if you connect it. Your Telegram chat id and username, to send your alerts.
• X, if you connect it. Your X account and username, and the “tweet a trade” settings and limits you choose.
• Keys for AI assistants. The keys you create for the MCP endpoint, so we can check them and you can delete them.
• Drafts without an account. A one-way hash of your IP address, so we can count the free drafts and tests per day. The address itself isn’t stored.
• Server logs. Technical logs of requests and errors, kept for a short time to keep the service running.

We never see your private keys. Wallets created in Melyon are held by Privy, and the permissions Melyon uses to trade for you can’t move money out of your wallet or your Hyperliquid account.

Melyon has no public side. It doesn’t publish your strategies, results or account, and nobody else using Melyon can see them. Two things are public anyway:

• Your trades on Robinhood Chain and Hyperliquid, which are public on those networks like any other on-chain activity. Anyone who knows your address can see them.
• If you use “tweet a trade”, your tweet and Melyon’s reply to it. The reply never shows amounts.

• Privy runs sign-in and the embedded wallets.
• Anthropic receives the text and any pictures of a trade idea when you ask Melyon to draft or change a strategy. Nothing else about you is sent.
• Market data providers (DexScreener, GeckoTerminal, Hyperliquid and the Robinhood Chain RPC) answer Melyon’s requests for prices, charts and on-chain data. Those requests can include the token and wallet addresses your strategies watch, including your own.
• KyberSwap receives the details of a Robinhood Chain swap (the tokens, the amount and your wallet address) to find a route for it.
• Robinhood Chain, Uniswap, Pons and Hyperliquid receive your orders and transactions, as they would from any app.
• Telegram and X deliver your alerts and handle “tweet a trade”, if you connect them.
• Our hosting providers run Melyon’s server and website.

We don’t sell data and don’t share it with anyone else, unless the law requires it.

If you give an assistant such as Claude or ChatGPT a key to Melyon’s MCP endpoint, it can read your runs. What it reads then goes to that assistant’s provider, under their privacy terms, not ours.

The site stores a few settings in your browser, such as light or dark mode and chart preferences. Privy stores what it needs to keep you signed in. There are no advertising or tracking cookies.

You can disconnect Telegram and X in Settings, delete the keys you made for AI assistants, and export your wallet keys. To see or delete the data tied to your account, message us on X. Deleting your account doesn’t touch your wallets or the money in them; that stays yours. Trades already made stay on-chain, where nobody can delete them.
