What are cookies?

Cookies are small text files that a website may store in your browser or on your device. They help provide basic website functions, maintain a user session or remember certain technical settings.

Cookies cannot by themselves run programs or transmit viruses to your device. Their content and purpose depend on the specific website and service used.

Which cookies do we use?

merkle.sk uses one first-party strictly necessary cookie. It is created when you visit the contact page and is required for the secure operation of the form.

Overview of cookies used on merkle.sk

merkle_contact Merkle s. r. o.

Contact form session security, protection against unauthorised form submission (CSRF), and display of the submission result directly on the page. Strictly necessary, first-party cookie Until the browser session ends

This cookie does not contain the text of your message or the data entered into the contact form.

Cloudflare Turnstile

On the contact form pages we use Cloudflare Turnstile to protect the site against automated attacks, spam and form abuse. The service is loaded only on /sk/kontakt/ and /en/contact/.

During the security check, Turnstile may process technical signals such as the IP address, TLS fingerprint, User-Agent header, public site key and page origin. These data are used to distinguish legitimate visitors from automated systems and to protect the website.

The Pre-clearance feature is not enabled. This means that Turnstile is not configured to issue the verification cookie cf_clearance for other pages of the domain.

Cloudflare states that Turnstile data are not used for advertising retargeting. Further information is available in the Cloudflare Turnstile privacy information .

How can you manage cookies?

You can view, delete or block cookies in your browser settings. The exact procedure depends on the browser and device you use.

If you block all cookies, most of merkle.sk will remain accessible, but the contact form may no longer function correctly because it will not be possible to create a secure session and validate the submission.

Changes to this policy

We may update this policy if the technical setup of the website, the services we use or the applicable legal requirements change. The current version will always be published on this page and marked with the date of the latest update.
