Cookie policy

What this policy covers

This policy explains how the chemlinkai website uses cookies and similar local storage. When you first visit, the consent banner offers two choices — “Accept all” or “Essential only” — and this site never enables analytics cookies before you choose “Accept all”.

Essential cookies

Essential cookies and local storage are required for the site to function correctly. In particular, we store your cookie choice in your browser so the consent banner does not reappear on every visit. Essential storage does not require consent and does not include advertising or cross-site tracking.

Analytics cookies (with your consent)

If you choose “Accept all”, we enable an analytics service that measures content performance — for example which pages are read, for how long, and from which region. Reports are aggregated and are used to improve the site’s content and structure.

Analytics cookies run only after your consent and stay off under “Essential only”. They are not used to identify you personally or to build advertising profiles.

Managing and withdrawing your choice

You control cookies through the banner and through your browser:

• Choosing “Essential only” disables analytics cookies for this site.
• You can withdraw or change consent at any time by clearing this site’s cookies and site data in your browser settings — the banner will then appear again on your next visit.
• Most browsers also let you block or delete cookies globally, or per site, through their privacy settings.
