Privacy policy

The controller of your personal data is 4NS Sp. z o.o., ul. Aleja Jana Pawła II 27, 00-867 Warszawa, Polish tax ID (NIP) 1133086610. For any matter concerning your data, you can write to us at the email addresses listed in the “Contact” section.

If you call or email us, we process the data you provide (such as your name, phone number, email address and the content of your message) solely to respond and to continue our conversation. The legal basis is our legitimate interests (Art. 6(1)(f) GDPR). Providing this data is voluntary, but without it we will not be able to respond. We retain correspondence for as long as necessary to handle your inquiry or as required by law.

This website uses no cookies or other tracking technologies. Your chosen theme (light, dark or system) is stored only in your browser (localStorage) and is never sent to us.

We use Vercel Web Analytics and Vercel Speed Insights. Both work without cookies, do not store IP addresses or identifiers, and distinguish visits using an anonymous hash that resets every 24 hours. They collect only aggregated data (such as the page visited, device and browser type, country and load times) that cannot be used to identify you. We use this data to check that the site is fast and works correctly.

The website is hosted by Vercel Inc., which acts as our processor. On every visit, the server automatically records technical data (IP address, date and time, the URL of the page requested and browser information). Logs are retained for a short period and used solely to ensure the security and proper operation of the site. The legal basis for this processing is our legitimate interests (Art. 6(1)(f) GDPR).

Your data may be disclosed only to entities that process it on our behalf (processors): Vercel Inc. (hosting and statistics) and our email service provider. Where data is transferred outside the European Economic Area, the transfer is based on standard contractual clauses adopted by the European Commission or on the EU-U.S. Data Privacy Framework.

We do not subject you to automated decision-making, including profiling.

With regard to the processing of your data, you have the right to:

• access your data
• have it rectified
• have it erased
• restrict its processing
• object to its processing
• lodge a complaint with a supervisory authority, in particular with the authority competent for us: the President of the Personal Data Protection Office (Prezes Urzędu Ochrony Danych Osobowych, PUODO) in Poland
