Privacy notice

This page explains what data I receive through this site, why it sets no cookies, and how to ask for it to be deleted. Published on 18 August 2026.

What I collect

This site has no data-collection forms of its own. The only data I receive about you is what you choose to send me directly: through the Cal.com booking form on the Contact page, or by email, to geral@cerzo.pt. I do not ask for or collect anything beyond that.

Cookies

This site sets no cookies. There is no analytics or tracking code running on it.

Cal.com, a third party

The Contact page has a button that reveals the booking calendar. Only after you click that button does your browser contact Cal.com (app.cal.com) — before that, no request is made to that service. From the click onward, booking happens through Cal.com, an external service with its own rules. If you would rather not use it, you can book by email, at geral@cerzo.pt.

How to ask for your data to be deleted

To ask to see, correct, or delete the data I hold about you, write to geral@cerzo.pt. I handle these requests myself, directly.

Who handles your data

The data described on this page is handled by David Carvalho — Cerzo —, at the same contact as the footer: geral@cerzo.pt. Tax identification number PT234047976, registered in Loures, Portugal.
