## This website

www.x402aff.xyz is a static site. It runs no advertising scripts, has no forms, and has no accounts. The only analytics it runs is Google Analytics, described below.

The site is hosted on Vercel. Like any web host, Vercel processes the technical data every request carries, such as your IP address, user agent, and the page requested, to deliver the site and protect it from abuse. That processing is covered by Vercel's privacy policy.

## Google Analytics

The site uses Google Analytics to count visits and see which pages people read. It sets first-party _ga cookies to tell repeat visits apart and sends Google your IP address, browser details, and the pages you view. Google processes that data under its own privacy policy. You can block it with a content blocker or the Google Analytics opt-out add-on.

## The x402aff SDKs

The npm and PyPI packages run entirely on your own server. They send no telemetry to the maintainers. They only make the network calls you configure: reads to the Base RPC you choose, and, if you use discovery, queries to the Coinbase Developer Platform SQL API with your own credentials.

Payments settle on Base mainnet, a public blockchain. Payer and recipient addresses, amounts, and builder-code attributions are public by design and cannot be deleted by anyone.

## Links to other sites

This site links to GitHub, npm, PyPI, Basescan, X, and other services. Their own privacy policies apply once you follow a link.

## Questions and changes

Email privacy questions to aaron@aeon.fun, or ask through a GitHub issue or on X (see the contact page). If this policy changes, the date on this page changes with it.
