Cookie Policy

Last updated: 2026

Overview

This website uses cookies and similar technologies to enhance your browsing experience. This policy explains how we use these technologies and what your rights are.

What is a cookie?

A cookie is a small text file stored on your computer or mobile device when you visit a website. Cookies are widely used to make websites function properly or more efficiently, as well as to provide information to website owners.

How do we use cookies?

We use PostHog, an analytics tool hosted in the European Union, to understand how our visitors use our website. This helps us improve our service and provide a better user experience. When you accept tracking, PostHog collects information such as:

No tracking cookies are set until you explicitly accept them.

Data processor

Analytics data is processed on our behalf by PostHog as a data processor, on infrastructure located in the European Union (Frankfurt). No analytics data leaves the EU. PostHog's data processing agreement is available at posthog.com/dpa.

Your rights and choices

You have the right to choose whether or not to accept cookies. While some cookies are necessary for certain basic site functionalities, you can choose to disable analytics tracking at any time.

Audience measurement (Vercel Analytics)

We also use Vercel Analytics for aggregated audience measurement. Vercel Analytics does not use cookies and does not store any persistent identifier on your device. Instead, it computes a daily-rotating hash from your IP address and user agent, which makes it impossible to track you across sessions or across websites. Because no information is stored on or read from your device, this measurement does not require prior consent under the ePrivacy Directive and falls within the audience-measurement exemption applied to privacy-friendly analytics.

You can still opt out of this measurement at any time. We also automatically honour your browser's Do Not Track signal when it is enabled.

Vercel Analytics runs by default because it does not use cookies or persistent identifiers. You can still opt out — your choice is stored locally in this browser. Current status: Audience measurement enabled

We reserve the right to modify this cookie policy at any time. Any changes will take effect immediately after the updated policy is posted on this website.
