We use your name, email address and message to reply and to continue the correspondence — including about possible cooperation. The website does not store messages; it only keeps a cryptographic hash of your IP address for one hour to protect the form from spam. The legal basis is our legitimate interest (Art. 6(1)(f) GDPR). Providing the data is voluntary, but the form cannot be sent without it.

When you start filling in the form, the page loads Cloudflare Turnstile, which checks that the message is being sent by a person rather than a bot. To do this, Cloudflare processes your IP address and information about your browser — for this purpose only (details in our privacy policy).

Your message goes only to our mailbox. Only our hosting and email providers and Cloudflare may have access to the data — if they process it outside the European Economic Area, they do so only on the basis of an adequacy decision of the European Commission or standard contractual clauses. Messages that do not lead to cooperation are deleted once the correspondence ends; if we sign a contract, we keep them until claims under it become time-barred.

You have the right to access, rectify and erase your data, to restrict its processing and to object. You can also lodge a complaint with the President of the Personal Data Protection Office (UODO) in Poland.
