1. What is a cookie

A cookie is a small data file your browser stores on your device when you visit a website. Cookies help the site recognise your browser and remember certain preferences.

2. What cookies we use

4dgroup.hu only places cookies that are technically necessary for the site to function. We do not use marketing, tracking, or advertising cookies, and we do not run third-party analytics cookies.

3. Specific cookies

• Session and language cookie — preserves your selected language (HU/EN) during the visit. Lifetime: until browser close or 1 year.
• Supabase auth cookie — only set if you sign in to a restricted area on 4dgroup.hu (e.g. admin). Maintains your login. Lifetime: until logout.
• Vercel-set technical cookie — security/CDN cookie set by our hosting provider. Lifetime: up to 24 hours.

4. Consent

Because we use only strictly necessary cookies, EU law does not require separate consent. You may still disable cookies in your browser settings — this may limit some features of the Service.
