Privacy Policy

Paywright is a free, open-source developer tool for testing x402 endpoints on testnet. This page explains, in plain language, what data it does and does not handle. It is a summary for transparency, not legal advice.

No accounts or personal data

Paywright has no sign-up and no login. It does not ask for your name, email, or any personal information, and it does not create a profile about you.

Your wallet

When you connect a wallet (through Reown AppKit / WalletConnect), your public address is used in your browser to read your USDC balance and to sign payments. We do not store your address. Paywright never has access to your private keys or seed phrase, and never asks for them.

The request proxy

To get around browser CORS restrictions, the requests you send are forwarded through Paywright's server to the target endpoint. The URL, headers, and body you enter pass through the server only to make that request, and the response is returned to you. We do not store this content in a database. As with any web server, our host (Vercel) may keep short-lived platform logs containing standard request metadata such as IP address. Do not send secrets through the proxy that you would not want transmitted to the target endpoint or briefly logged.

Local storage

Your recent requests are saved in your browser's localStorage, on your device only. They are never sent to us. You can clear them at any time with the "clear" action or by clearing your browser storage.

Third-party services

Paywright relies on services that have their own privacy practices:

• Reown / WalletConnect, for wallet connection
• The public x402 facilitator and RPC providers, for on-chain reads and settlement
• Block explorers, for the links to transactions and addresses
• Vercel, for hosting

Your use of those services is subject to their own policies.

Analytics

Paywright does not run its own custom analytics or tracking cookies, but some usage data is collected by the services it runs on:

• Reown, our wallet-connection provider, processes wallet connection events for usage analytics.
• Vercel, our host, keeps standard server logs (such as IP address and request metadata), as any web host does.

This data is handled under those providers' own privacy policies. We use it only to understand usage and keep Paywright running. If we add anything else, we will update this page.

Testnet

Paywright operates on the Base Sepolia testnet and does not handle real funds.

Changes

We may update this policy. The "last updated" date above reflects the current version.
