Cookie Policy
Effective date: 6 July 2026 · English version is authoritative.
1. Introduction
This Cookie Policy explains how benchmarkfree.dev (“BenchmarkFree”, “we”, “us”) uses cookies and similar technologies on https://benchmarkfree.dev. It supplements our Privacy Policy.
The English version of this policy is authoritative.
2. What are cookies?
Cookies are small text files stored on your device when you visit a website. We also use similar technologies (such as local storage where applicable) for essential preferences.
3. Cookies we use
| Name | Provider | Purpose | Duration | Category |
|---|---|---|---|---|
| llm_eval_session | BenchmarkFree | Keeps you signed in after authentication (HttpOnly session cookie) | Session or as configured for your deployment (typically up to 30 days) | Strictly necessary |

4. Analytics
We use Google Analytics 4 (Google LLC) to understand how visitors use the Service — for example which pages are viewed and how users navigate the site. Google may set analytics cookies (such as _ga) and process usage data according to Google's Privacy Policy. You can opt out via Google's browser add-on or your browser cookie settings.
We may also use Cloudflare Web Analytics to understand aggregate page performance. That product is designed to be privacy-oriented: it does not use third-party tracking cookies for cross-site profiling and does not sell visitor data.
Analytics help us operate and improve the Service. Where required by law (for example in the EU/UK), we will obtain consent before using non-essential analytics cookies.
5. Managing cookies
You can block or delete cookies through your browser settings. Blocking strictly necessary cookies (such as the session cookie) will prevent you from staying signed in and may limit core functionality.
For EU/UK visitors, non-essential cookies (including Google Analytics) will only be used where we have a valid legal basis, such as consent where required.
