Privacy

What this site collects, which is little, and who is responsible for it. Effective 22 October 2026.

What this page covers

This page covers hurdle.run, the site that describes Hurdle, and nothing else.

Hurdle is a product of Ambitious Machines, Inc., a Delaware corporation. It is not a separate company. “We” on this page means Ambitious Machines, Inc.

What this site collects

There is no account to create, no form to fill in and no newsletter. The site sets no cookies of its own and stores nothing in your browser. The typefaces are served from this domain rather than from a font service.

It sends the pages you view and clicks on the email links on this site, Book a walkthrough among them, to PostHog (PostHog, Inc., United States), which we use to see which pages are read and how long a visit lasts. PostHog sets no cookie, stores nothing in your browser and does not record your screen. It receives your IP address and browser details with each request, and uses the address to estimate a rough location.

What the host records

The site is a set of static files served by Cloudflare. Cloudflare records each request: the IP address it came from, the time, the page asked for and the browser’s user agent. That exists to deliver the page and to defend it against abuse.

We do not join those records to anything else and do not use them to build a profile of a visitor.

Published results

The benchmark results on this site are files about models, not about people. The open benchmarks are built from invented employers and invented workers, and no published file holds personal data.

What we do not do

We do not sell information about you, and we make no automated decisions about anyone. We build no profile of a visitor, and PostHog keeps no profile of you either.

Your rights under the GDPR

You may ask for a copy of personal data held about you, ask for it to be corrected or deleted, object to how it is used, ask for its use to be restricted, and complain to your data protection authority. The site itself holds nothing about you. What PostHog records sits with it, and we will help with a request about it.

Changes

This page carries the date it took effect, at the top. If what the site does changes, this page changes with it and the date moves. There is no archive of earlier versions, because there has not been an earlier version.
