Cookie Policy
Last updated: 11 May 2026
1. What cookies are
Cookies are small text files stored on your device when you visit a website. They allow the site to remember your actions and preferences over time. Quantum Dynamics uses cookies as described below, in accordance with the GDPR and the ePrivacy Directive.
2. Categories we use
Essential (always on)
These are required for the site to function. They cannot be disabled. They handle session state, security (CSRF token), and load balancing.
Functional (consent required)
Remember your UI preferences, for example language and theme. Disabling them means the site forgets your settings between visits.
Analytics (consent required)
We use Vercel Analytics to understand which pages people read and how they navigate. The data is aggregated and does not identify you personally. Disabling them means we do not collect any usage data from your session.
Marketing (currently unused)
We do not run advertising pixels, retargeting scripts, or third-party marketing cookies. This category remains in the consent banner as a placeholder. If we ever add marketing cookies, your previous consent choice for this category will be honoured.
3. Third-party cookies
Stripe
During checkout, Stripe Payments Europe Ltd. sets cookies strictly necessary to process the transaction and prevent fraud. These are loaded only when you reach the checkout flow.
Vercel
Our hosting provider sets a small number of essential cookies for load balancing and security. These do not track you across sites.
4. Your rights and control
You can change your consent at any time. Click "Cookie settings" in the footer to reopen the preferences panel.
You can also delete cookies via your browser settings:
- Chrome: Settings → Privacy & security → Cookies and other site data
- Firefox: Settings → Privacy & Security → Cookies and Site Data
- Safari: Preferences → Privacy → Manage Website Data
Note: if essential cookies are blocked, the site may not function properly.
