The data controller is Mateusz Kornaś, contact: [email protected].
Short, honest policy — because the site is simple and I don't collect more than I have to.

Only what you submit through the contact form: name, email, and message body. I use this data only to reply to your inquiry.
This site uses necessary cookies (e.g. remembering your banner choice). With your consent, I also use Google Analytics 4 to understand how visitors use the site — it then sets its own cookies. Without consent, analytics stores no identifying data (Google Consent Mode). You can withdraw consent anytime by clearing cookies in your browser. The provider is Google (Google Ireland Ltd.) acting as a processor; data may also be processed outside the EEA under standard contractual clauses.
My server keeps technical logs (IP address, request time, URL path) for diagnostics and security. Logs are retained for at most 30 days.
Contact-form messages are sent through my hosting provider's mail server (webd.pl, wn25.webd.pl). The provider acts as a data processor — it handles your email and message only to deliver it to my inbox.
You have the right to access, correct, and delete your data, and to file a complaint with the Polish data-protection authority (UODO). For anything related, email [email protected] — I usually reply the same day.
I may update this policy. The last-updated date is shown at the bottom of this page.
