Cookies
Necessary storage always works. Analytics and marketing cookies only with your consent — and you can change your choice at any time.
Your choice
On your first visit a banner offers Accept all, Necessary only and Settings. Until you choose, the website loads nothing from Google. Change your choice here:
Necessary (always on)
- sferin-suhlas (browser storage) — remembers your cookie choice until you change or clear it.
- Cloudflare (cookie __cf_bm, 30 minutes) — protects the website against malicious bots. Operated by Cloudflare, Inc.
- Cloudflare Turnstile — checks that a submitted form is not sent by a bot. It processes technical browser data, not for tracking.
Analytics (only with consent)
- Google Analytics 4 via Google Tag Manager (Google Ireland Limited) — cookies _ga and _ga_R9J9HM1W3C, 13 months. Anonymous statistics of visits and clicks on calls to action (e.g. opening an email, the calculator, the language switch). We keep the data in Google Analytics for 14 months; IP addresses are not stored.
- Short-lived entries in session storage (m:…) so that some events are counted only once per visit. They disappear when you close the window.
Marketing (only with consent)
We do not run ads yet, so the website stores no marketing cookies. If we ever switch them on (e.g. Google Ads measurement), they will load only with this consent and we will list them here.
Withdrawing consent
When you withdraw analytics consent, the website deletes the Google Analytics cookies on sferin.sk and stops measuring. You can also delete cookies in your browser settings. More in our Privacy policy.
