What and why

When you use a form on this site, we process what you type into it (typically name, work email, company, your message or order details) to reply to you and to deliver what you ordered. The legal basis is performance of a contract, or our legitimate interest in responding to your enquiry. When you subscribe to report notifications, we use your email to send them, until you tell us to stop. If we email you about our work, we use work contact details (name, job title, company and work email) that your company publishes or that a business contact database (Apollo.io) provides, based on our legitimate interest in offering our services to businesses. Reply “no” and we will not write again; we keep only your address on a do-not-contact list.

What we do not do

This site sets no advertising or tracking cookies and runs no profiling. Our analytics is cookie-less and aggregated; it does not identify you. If you arrive from a campaign link, its reference is kept in your browser for the duration of your visit only, so we know which campaign an order or enquiry came from. Our measurements analyze brands and public AI systems, not people.

Who helps us

A hosting provider, a web analytics provider, a transactional email provider and a business email provider process data on our behalf under their standard data processing terms. We name them on request.

How long

Enquiries and orders are kept as long as needed to serve you and to meet Czech accounting and tax obligations; notification subscriptions until you unsubscribe; contacts we have written to for up to 24 months after our last email.

Your rights

You can ask what we hold about you, have it corrected or deleted, object to processing, and complain to the Czech Office for Personal Data Protection (ÚOOÚ). Just write to us.
