Privacy

This is my personal website. This page explains what it measures and what it stores in your browser.

What I measure

I use Google Analytics 4, loaded through Google Tag Manager. It shows me how many people visit, which pages they view, how they found the site (for example from a search engine or a link) and which external links they open.

Before you choose

Until you allow analytics cookies, nothing is stored in your browser for analytics. Google receives only basic signals without cookies, such as that a page was viewed. They are used for aggregated, modelled reports and cannot recognise you on your next visit. Advertising signals are always off.

If you allow analytics

Google Analytics sets the _ga and _ga_* cookies, which recognise a returning browser for up to two years. Detailed visit data is kept for 14 months. Google Analytics does not store IP addresses.

Who processes the data

Google Ireland Limited processes the data on my behalf. It may be transferred to Google LLC in the United States under the EU–US Data Privacy Framework.

What else the site stores

The portfolio-color-mode cookie remembers your light or dark theme, and portfolio-consent remembers your choice about cookies. Both are needed for the site to work as you set it, and neither is used for tracking.

Your choice and your rights

You can change or withdraw your consent at any time. You also have the right to ask what data is held about you, to have it deleted, and to complain to the Czech Office for Personal Data Protection (ÚOOÚ). For questions, message me on LinkedIn.
