Privacy & data use
The calculators run in your browser. No account is needed to use them.
Calculator inputs
The site's calculator code does not send your ride duration, weight, FTP, recipes or prices to a database or analytics service. It does not use cookies or browser storage to save your settings. Reloading a page normally returns to its defaults unless the address contains a shared plan.
Sharing a plan
When you choose Share or Copy in the fuel planner, the settings are included in a link's fragment, after the # symbol, and in the copied text. This includes entered prices. Anyone you send the link or text to can see those settings. A recipient or the service you share through may retain them.
The site does not intentionally send fragment settings to the hosting server. A short homepage-to-planner link may contain only a duration and intensity setting. Do not put sensitive information into shared links.
Hosting and technical data
The website is hosted using Sites, with Cloudflare infrastructure. Hosting and security providers may process technical request data, such as IP addresses, browser information and access logs, or use essential security mechanisms. This page does not claim that the hosting layer stores no data.
For provider practices, see OpenAI's privacy policy and Cloudflare's privacy policy.
Analytics, advertising and external links
No advertising pixels, third-party analytics scripts or newsletter forms are included in the current site code. Fonts and calculator assets are served with the site.
External links take you to services with their own privacy terms. Retailer search links are not affiliate links. See the affiliate disclosure.
Scope of this notice
This notice describes the current implementation, not a guarantee about every browser, device or third-party service. If the site introduces accounts, analytics or monetisation, this information must be updated before those features are used.
