Last updated: February 2026. This policy explains which cookies we use on c5s.xyz, what they do and how to manage them.
Cookies are small files that a website stores in your browser when you visit it. They allow remembering preferences, keeping sessions and getting usage statistics. Some are essential for the site to work; others are optional and only activate with your consent.
On c5s.xyz we use a minimal set of cookies, grouped in two categories:
Needed for the basic functioning of the Site: remembering the chosen language, visual theme (light or dark) and your preference on the cookie banner. They don't require consent because they are essential to deliver the service you've requested.
If you grant consent, we activate privacy-friendly analytics that help us understand which pages are most useful, which devices are most used and how to improve content. These cookies do not collect personally identifiable information. If we later activate Google Analytics, it will be with IP anonymization and only after your explicit consent.
By default we load Vercel Web Insights and Vercel Speed Insights, two analytics tools that do not use cookies and do not track users across sites. They collect aggregated metrics about performance and usage to help us keep the Site fast and useful.
You can accept or reject optional cookies from the banner that appears the first time you visit the Site. To change your choice afterwards you can: (a) delete cookies in your browser so the banner reappears; (b) configure your browser to block or delete cookies in general (note that rejecting essential cookies may affect the Site's functioning).
For details on how we process personal data, see our Privacy Policy. For any inquiry, write to team@c5s.xyz.
