BrewDex is designed to work without accounts. This page explains what data the Interface uses, where it stays, and which third parties receive it so the Interface can work.

1. No account, no identity checks

You do not create an account and we do not ask for your name, email, phone number, or identity documents. BrewDex never receives your private keys or recovery phrase.

2. Data the Interface uses

DataWhyWhere it goes
Public wallet addressShow balances, build swap quotes and transactionsYour browser; our server forwards it to the swap router (OKX DEX or Binance Web3) when you request a quote or swap; public BNB Chain RPC providers. On Solana: our server forwards it to OKX DEX for swaps and to Helius to list your tokens in the Portfolio, and your browser sends it to PublicNode (a public Solana RPC) to read balances
IP addressRate limiting and abuse preventionKept in short-lived (about 60 second) rate-limit counters; standard request logs of our hosting provider; GeckoTerminal, DexScreener, DefiLlama, PublicNode and public BNB Chain RPC providers, which your browser contacts directly for prices, charts and chain data
Anonymous visitor ID (a random code created in your browser), the time of your last visit, and your public wallet address if you connect oneCount visitors (online now, unique visitors per day) without counting the same browser or wallet twiceOur database (Supabase), sent about once a minute while a BrewDex tab is open, only after you accept these policies. It contains no name, email, or IP address
Token addresses you view or searchLoad prices, charts, and token dataMarket data providers listed below

3. Stored only in your browser

These stay in your browser's local storage and are never sent to BrewDex servers:

  • Preferences: theme, language, table layout, sound.
  • Your swap history on this device (BNB Chain and Solana).
  • The Solana token list your browser builds from public market data, so the next visit starts with it.
  • The optional device lock: a salted PIN hash and a passkey credential ID.
  • Your acceptance of these policies (date and version).

The anonymous visitor ID is also kept here; it is the one item sent to BrewDex (see section 2).

Clearing your browser data removes them. BrewDex does not set tracking cookies.

4. Third-party services

To show data and build swaps, requests are sent to:

  • Swap routing: OKX DEX (BNB Chain and Solana), Binance Web3.
  • Market data: GeckoTerminal, DexScreener, DefiLlama, four.meme, brew.family, Binance Web3.
  • Blockchain access: public BNB Chain RPC providers; PublicNode and Helius for Solana (balances, token checks, holder data and your Portfolio); WalletConnect / Reown if you connect by QR code; the Solana wallet you connect (for example Phantom, Solflare or Backpack).
  • Hosting and storage: Vercel (hosting) and Supabase (cached public market data and anonymous visitor statistics).
  • Fonts: Google Fonts.

Optional, only when enabled by the operator: error reports (Sentry), which exclude wallet addresses, request headers, bodies, and query strings; and privacy-friendly page analytics (Vercel Web Analytics).

Each service handles data under its own privacy policy.

5. Public blockchain data

Transactions you sign are recorded publicly and permanently on BNB Chain or Solana. BrewDex cannot change or delete on-chain data.

6. Sale and sharing

We do not sell personal data and do not use it for advertising.

7. Your choices

  • You can use the market pages without connecting a wallet.
  • You can disconnect your wallet and clear local data at any time from your browser.
  • Swap history can be cleared from the Portfolio window.

8. Changes

We may update this policy; the date above shows the current version, and material changes are shown to you again in the Interface. See also the Terms of Service.
