Version 0.1 · draft of 12 November 2026 · not yet in force
01 / Consent principleReal choices / Clear defaults
Person first / Preferences
Saying no is
as easy as yes.
Declining is as easy as allowing, and nothing optional runs until you choose. This page says what the site stores, and lets you change your mind at any time.
02 / Cookie preferencesOptional is off by default
Your choice / Kept for 12 months
Your data. Your decision.
The site has one optional technology: Microsoft Clarity, which shows how the pages are used. It stays off until you allow it.
There are no advertising or marketing cookies here.
03 / Cookie policyDraft / Before legal review
What is stored. And why.
- Without consent the site stores only what it needs to work.
- Microsoft Clarity starts only if you allow it.
- You can change your choice at any time in the preferences on this page.
What cookies are
Cookies are small files a website keeps in your browser. Browser storage works in a similar way. On this page both are called cookies.
What the site stores without consent
Without consent the site stores only what it could not work without. Such storage needs no consent (Section 89(3) of Czech Act No. 127/2005 Coll.).
- dc-consent
- Remembers your choice about analytics (Allow or Decline). Kept for 12 months.
- theme (browser storage)
- Remembers the light or dark theme you chose. It stays in your browser and is sent nowhere. Kept until you clear it.
Analytics: Microsoft Clarity
Only if you choose “Allow” does the site start Microsoft Clarity, a tool that shows how the pages are used.
Clarity records which pages you view and where you came from, where you click, how you scroll and move the pointer, your device, browser and screen size, your IP address and the approximate location derived from it. From this come recordings of visits and heat maps, which we use to make the site easier to use.
What you type into a form is masked, and Clarity never runs on the page that confirms a form you have sent. We send Microsoft a consent signal for analytics only, never for advertising storage.
What Clarity stores
After your consent Clarity may store these cookies and data:
- _clck (this site)
- The visitor’s identifier in Clarity and its settings, so that later visits can be connected. Kept for 12 months.
- _clsk (this site)
- Connects the page views of one visit into one recording. Kept for 1 day.
- _cltk (this site, session storage)
- Identifies the browser tab, so that recordings from several tabs are not mixed. Kept until the tab is closed.
- CLID (clarity.ms)
- Microsoft’s identifier by which Clarity recognises the browser on other sites that use Clarity. Kept for 12 months.
- MUID (clarity.ms)
- Identifies the browser across Microsoft’s services; according to Microsoft, for analytics, advertising and operations. Kept for up to 13 months.
- MR, SM, ANONCHK (clarity.ms)
- Microsoft’s technical cookies that refresh and synchronise the MUID identifier. Kept for up to 7 days.
On what legal basis
Analytics runs only on the basis of your consent, both for storing the cookies on your device (Section 89(3) of Act No. 127/2005 Coll.) and for processing the personal data Clarity records (Art. 6(1)(a) GDPR).
Microsoft as an independent controller
Clarity is operated by Microsoft Ireland Operations Limited, One Microsoft Place, South County Business Park, Leopardstown, Dublin 18, Ireland. We are responsible for starting Clarity on this site and for the data being passed to Microsoft. Microsoft then handles the data as an independent controller under its own privacy statement and may use it for its own purposes, such as improving its services and advertising.
Microsoft may transfer the data to Microsoft Corporation in the USA, which is certified under the EU–US Data Privacy Framework; the transfer is also covered by the European Commission’s standard contractual clauses.
Changing your choice
You can change your choice at any time in the preferences on this page; “Cookie settings” in the footer of every page leads straight to them. Withdrawing consent is as easy as giving it and does not affect what was processed before.
After a withdrawal the site stops starting Clarity and removes its cookies from this site. Microsoft’s cookies on its own domains can be deleted in your browser’s settings.
Your browser can also block or delete cookies. If you block the necessary ones, the site will ask for your choice on every page.
How long
Every item has its own period, given in the tables above. The site remembers your choice for 12 months and then asks again.
In Clarity we can see recordings of visits for 30 days, and selected recordings and heat maps for 9 months at most. How long Microsoft keeps the data for its own purposes is set by its privacy statement.
Changes to this policy
When the cookies on the site change, this policy changes too, with the date from which the new version applies. If a cookie that needs consent is added, you are asked again.
04 / Honest contentNo surprises / No manipulation
Four rules for the cookie bar.
01 / Understand
Readable.
What each cookie is for, in ordinary words.
02 / Decide
Equal choice.
Decline and allow carry the same weight.
03 / Return
Reversible.
One click from every page to change your mind.
04 / Verify
Auditable.
What the page says is what the code does, and that is tested.
05 / Real-world implementationInventory / Gate / Document / Test
The interface is only the start.
A cookie bar is only honest if the scripts behind it obey it. The choice you see, the choice that is stored, and what the analytics actually does have to match.
Identify every technology.
List every script, everything stored, every provider, and what each is for.
Enforce the choice.
Optional scripts load only when the law and the visitor’s choice allow them.
Document clearly.
Publish what each category does, how long things are kept, and who to contact.
Test every state.
Test the first load, saying no, saying yes, changing your mind, and all of it on a phone.
Independent by design / Built to stand apart
Trust is Designed Into details.
