1. What are cookies

Cookies are small text files that may be used by websites to make the user experience more efficient. They can be stored on your device (computer, mobile, tablet) and contain a short string of characters that allows the website to recognize you on your next visit, remember your preferences (e.g., language), or measure how you use the site.

We use cookies (as the website operator) and third parties (Google), whose tools we operate on the website.

2. Legal basis and your consent

The law (§ 89(3) of Act No. 127/2005 Coll. on Electronic Communications, as amended from January 1, 2022) states that we may store cookies on your device only if they are strictly necessary for the operation of this site. For all other types of cookies, we need your active permission (opt-in).

On your first visit, you will see a cookie banner where you can accept, reject, or adjust individual categories of cookies according to your choice. Your decision is stored for 6 months.

You can change or withdraw your consent at any time via the "Cookie settings" button at the top of this page.

3. Cookie categories

We divide cookies into three categories by purpose:

Necessary (technical)

Necessary cookies help make the website usable by enabling basic functions such as page navigation, login to administration, or filling in a form. The website cannot function properly without these cookies. These cookies are set without your consent (legal basis — legitimate interest under § 89(3) ZoEK).

Statistical (analytical)

Statistical cookies help website owners understand how visitors use the website. They anonymously collect and report information so we can improve the site. We use Google Analytics 4. These cookies are stored only with your consent.

Marketing

Marketing cookies are used to track visitors across websites. The intent is to display advertisements that are relevant and engaging for the individual user and thereby more valuable to publishers and third-party advertisers. We use Google Ads. These cookies are stored only with your consent.

Below is a detailed list of cookies used on gwpklima.cz. Tables are divided by category.

5. Data transfer to third parties

Some cookies (analytical, marketing) are set by Google Ireland Ltd. as a processor within the Google Analytics 4 and Google Ads tools, which are operated on the website via Google Tag Manager.

Data processed by Google may be transferred to the USA. Google has committed to compliance with Standard Contractual Clauses (SCCs) and the EU-US Data Privacy Framework as the basis for international data transfer. More in the Google Privacy Policy.

6. Retention period

The retention period of individual cookies is listed in the tables in section 4. After expiration, cookies are automatically removed.

We store records of granted consent (consent logs) in our database for 3 years for the purpose of demonstrating consent according to Article 7(1) GDPR. The record contains a hashed IP address (SHA-256, does not allow reconstruction of the original IP), cookie categories, policy version, and timestamp.

7. Your rights and how to change consent

You have all data subject rights under GDPR — see Privacy Policy (right of access, rectification, erasure, restriction, portability, objection, lodging a complaint with ÚOOÚ).

You can change or withdraw your cookie consent at any time:

by clicking the Cookie settings button at the top of this page (opens a window with your current choices)
by changing your browser settings (may affect other websites too)
by clearing cookies in your browser (the banner will reappear on your next visit)

If you reject analytical or marketing cookies, you will not have limited website functionality — we just won't be able to track aggregated traffic statistics and you won't see targeted advertising based on your activity on our site.

8. Cookie policy updates

We may update this cookie policy at any time. In case of significant change (e.g., adding a new category of cookies or a new processor), we will ask you for new consent via the banner.

You can find the date of the last update in the header of this page.
