x402 Inspector Pro Privacy Policy

Effective date: July 26, 2026

Plain-language summary: x402 Inspector Pro decodes challenge data locally in the browser. It does not automatically inspect browsing activity, transmit pasted challenge data, store challenge data, run analytics, sell data, or connect to a wallet.

1. Scope

This policy applies to the Chrome extension named x402 Inspector Pro — Challenge Decoder. The extension lets a user manually paste an x402 payment challenge header or JSON payload, view locally decoded fields, and generate a basic cURL request template.

2. Information handled by the extension

The extension may temporarily process information that the user deliberately pastes into its popup, including public x402 challenge fields such as payment amount, network, asset, payment destination, resource URL, scheme, and description. This may constitute website content and financial or payment information under Chrome Web Store disclosure categories.

The extension also processes an endpoint URL when the user enters one to generate a cURL template.

3. Local processing, storage, and transmission

4. Sensitive credentials

The extension is not designed to receive wallet seed phrases, private keys, passwords, authentication cookies, signed payment credentials, or card information. Users should never paste such information into the extension. The extension displays an in-product warning against entering credentials.

5. Optional Stripe checkout links

The extension contains user-initiated buttons that open external Stripe checkout pages for optional hosted gateway subscriptions. Stripe—not the extension—processes information entered on those checkout pages. The extension does not receive, read, or store card numbers, wallet credentials, billing addresses, or Stripe checkout form contents.

6. Analytics, advertising, and sharing

7. Chrome Web Store Limited Use compliance

The extension’s use of user-provided challenge information is limited to providing its disclosed challenge-decoding and request-template functions. Data is not used for advertising, profiling, creditworthiness, unrelated product development, or any purpose unrelated to the extension’s single purpose.

8. Security

The extension contains no remotely hosted executable code. Its JavaScript and HTML are packaged with the extension and reviewed through the Chrome Web Store submission process. External subscription pages are opened using HTTPS.

9. Data deletion

Because challenge inputs are not persistently stored, users can remove them immediately with the Clear button or by closing the popup. The extension has no developer-controlled database containing challenge inputs.

10. Children

The extension is a developer utility and is not directed to children under 13.

11. Changes to this policy

This policy may be updated when the extension’s functionality or data practices change. The effective date above will be revised when material changes are made.

12. Contact

Privacy questions may be submitted through the support contact displayed on the extension’s Chrome Web Store listing.
