Privacy policy
Last updated: 8 August 2026
This site processes personal data only as needed to run the website, reply to contact requests and — with your consent — measure traffic (Vercel Analytics).
Data controller
The data controller is Piotr Kulbacki (sole proprietorship / Einzelunternehmen, Berlin).
Bendastr. 11, 12051 Berlin
Germany
Privacy contact: kontakt@piotrkulbacki.com
Hosting
The site is hosted by Vercel Inc. Technical logs (e.g. IP address, user agent, timestamp) may be created as needed for security and service stability.
Contact form
When you submit the form, your name, email, optional phone number and message are processed solely to reply (Art. 6(1)(b) or (f) GDPR). Messages are delivered via Brevo (Sendinblue GmbH, Germany) as a processor; you may also receive an automatic acknowledgement. Data is not sold or used for marketing without separate consent. It is kept only as long as needed to handle the request, then deleted or archived where legally required.
Analytics
After you accept analytics in the cookie banner, I load Vercel Analytics. It does not set its own tracking cookies; traffic is measured in a minimised way (e.g. request hash). Without consent, analytics stays off. Legal basis with consent: Art. 6(1)(a) GDPR.
Your rights
You have the right of access, rectification, erasure, restriction, data portability and objection — email the controller.
Supervisory authority
You may lodge a complaint with the competent data protection authority. For Berlin: Berliner Beauftragte für Datenschutz und Informationsfreiheit.
