Renewable Diesel Info does not offer accounts, and the pages do not set cookies. There is no comment form and no mailing list on the site. Advertising, when it exists, will be arranged by email at rm@zambmedia.com. This page is not a lawyer's privacy policy. It should be read by one before the site is treated as a finished legal notice.
Prices in the browser
The price ticker asks the site for /api/prices and keeps the answer in the browser's session storage under the key rdi-prices-v1. That copy stays on the device for the tab session so the next page does not have to fetch again immediately. It is not an account, and it is not sent anywhere except back from this site's own price address. If storage is blocked, the ticker still requests a fresh reading.
Hosting
The site is built to be hosted on Cloudflare Pages. Cloudflare processes the request, which includes the IP address and ordinary connection data, under Cloudflare's privacy policy. This repository does not include a Cloudflare Web Analytics token. If analytics is turned on in the Cloudflare dashboard, Cloudflare injects its beacon. Cloudflare describes Web Analytics as cookieless in its Web Analytics documentation.
