Privacy Policy
Last updated October 12, 2026
x402 Identity Hub (“the Hub,” “we,” “us”) is an open-source, fully client-side web application for minting ENS subnames under 402bot.eth, 402api.eth, and 402mcp.eth. The interface is static and served from Cloudflare at x402id.dev and from IPFS at x402id.eth. We do not operate a backend server that receives, stores, or profiles your personal information.
1. Information we do not collect
We do not run accounts, logins, email lists, or advertising pixels. The Hub does not ask you for your name, email address, or any personally identifying details. The only analytics we use is Google Analytics, described in section 5.
2. Information handled in your browser
When you connect a wallet, your wallet provider and the WalletConnect / Reown relay store a session locally in your browser (via localStorage) so the connection can persist across page loads. This data stays on your device and is cleared when you disconnect or clear your browser storage. We never transmit it to us.
3. Third-party services
Because the Hub interacts with the Ethereum blockchain, certain independent services necessarily process technical data such as your public wallet address and IP address:
- WalletConnect / Reown — relays the encrypted connection between the Hub and your wallet.
- RPC providers (e.g. Alchemy, public nodes) — read blockchain state and broadcast the transactions you sign.
- Cloudflare and IPFS gateways — serve the static files that make up this interface.
- Google Analytics — measures aggregate site traffic (see section 5).
These providers operate under their own privacy policies. We do not control and are not responsible for their data practices.
4. Onchain data is public and permanent
Minting an ENS subname is a public blockchain transaction. The label you choose, the parent name, your wallet address, and any records you set are written to Ethereum and to the public ENS registry. This information is permanent, globally visible, and cannot be deleted by us or by anyone. Do not mint a name or set records you are unwilling to make public forever.
5. Analytics and search engine verification
The site uses Google Analytics to understand aggregate traffic: which pages are visited, how visitors arrive, and their approximate region and device type. Google Analytics sets first-party cookies and processes your IP address under Google’s privacy policy. We do not send your wallet address or any onchain activity to Google Analytics. You can opt out with Google’s opt-out browser add-on or by blocking cookies for this site.
The site also includes Google Search Console verification tags so the domain owner can monitor indexing. These are verification signals only.
6. Children
The Hub is not directed to children under 13 and we do not knowingly collect information from them.
7. Changes to this policy
We may update this policy as the Hub evolves. Changes are published at this URL with a revised “last updated” date. Because the interface is also served from IPFS, prior versions may remain accessible at older content hashes.
