Privacy & cookies
Last updated: 2 October 2026
This personal website is operated by Krzysztof Kardasz, the controller of personal data collected through this site.
For privacy questions or requests concerning your personal data, contact support@nweb.pl.
Your choice
Analytics is optional. Google Analytics is loaded only after you select “Accept analytics”. Rejecting analytics does not limit access to any part of the site. Scrolling, following links or closing a page does not count as consent.
You can change your choice using “Cookie settings” at the bottom of every page. If analytics is enabled, “Withdraw analytics consent” switches it off in one click and removes this site's analytics cookies. Withdrawal does not affect the lawfulness of processing before withdrawal or automatically delete data already sent to Google.
Optional analytics
With your consent, Google Analytics 4 helps me understand which pages people visit and how they use the site. It processes cookie identifiers, page views, interactions, referral information, browser and device information, and approximate location. Your IP address is used when communicating with Google; Google states that GA4 does not log or store individual IP addresses.
The legal basis is your consent under Article 6(1)(a) GDPR. The site's tag disables Google signals, advertising storage, advertising user data and ad personalization. This site does not use analytics to make automated decisions with legal or similarly significant effects.
Google provides the analytics service, including Google Ireland Limited and Google LLC. Data may be processed outside the European Economic Area, including in the United States. Google describes its transfer safeguards, including the EU–US Data Privacy Framework and standard contractual clauses, in its international data transfer information. See also how Google uses information from sites that use its services.
Cookies & browser storage
kardasz-cookie-consent· required preference- Local storage records acceptance or rejection, the notice version and an expiry date for 180 days. It is used only to respect your choice. After expiry, analytics stays off until you accept again. The expired record is replaced when you make a new choice, or removed when you clear site data.
_gaand_ga_QJ9SRBWP54· optional analytics- First-party Google Analytics cookies distinguish browsers and maintain session information. The tag limits their lifetime to 180 days and disables automatic expiry renewal on page visits. They are removed from this site when you reject analytics or withdraw consent.
theme· requested display preference- Local storage remembers a light or dark theme when you select one. It remains until you select “Auto” or clear site data. It is not used for tracking.
Cookie expiry is separate from retention of data already collected by Google Analytics. The retention period for user-level and event-level analytics data is two months. New activity does not reset the retention period for user data. Google deletes expired data in its monthly deletion cycle. This limit does not apply to standard aggregated reports, which may cover longer periods. See Google's data retention documentation.

GitHub Pages hosts this website and processes technical requests, including IP addresses, to deliver and secure it. See the GitHub privacy statement for its handling of service data.

Where applicable, you can request access to, correction or deletion of your personal data, restriction of processing and data portability, and object to processing based on legitimate interests. You can withdraw analytics consent at any time using the controls below.
You may lodge a complaint with your local data protection authority, including the President of the Polish Personal Data Protection Office (UODO).
