LEGAL BASIS

This is exclusively storage that is strictly necessary to provide a service you have
expressly requested. Under § 89(3) of Act No. 127/2005 Coll., on electronic communications
(zákon o elektronických komunikacích), no consent is required for it. We provide information
about it on this page.

THIRD PARTIES

There are no third-party analytics, advertising or social media scripts on our website. The
Stripe payment page, to which you are taken when paying, runs on Stripe’s domain and uses
its own cookies, in particular for fraud prevention. It is governed by the Stripe policy
(https://stripe.com/cookies-policy/legal).

HOW TO DELETE THEM

You can delete cookies and local storage in your browser settings (Clear site data).
Deleting the mx_session cookie logs you out; deleting local storage removes an order in
progress that has not yet been submitted.

Should we ever want to use analytics or other non-essential cookies, we will ask for your
consent in advance and update this page.

Effective from 4 October 2026.
