Who is responsible
Dr Küçük, Switzerland. Questions or requests about your data: [email protected].
Analytics and cookies
We use Google Analytics 4 (through Google Tag Manager) to understand how visitors use the site: pages viewed, scrolling, clicks on outbound links, downloads and video use.
Visitors from the EU, EEA and UK: nothing is loaded from Google and no analytics cookies are set unless you choose Accept in the cookie bar. Visitors from elsewhere, including Switzerland: analytics is on by default; you can switch it off at any time with Decline in the cookie bar or below, and the analytics cookies are then deleted. We recognise the region only from the country our network provider (Cloudflare) reports for your connection.
Google Analytics sets its own cookies (named _ga…), does not store full IP addresses, and may process data in the United States. Advertising features are switched off. Data is kept for at most 14 months.
Your current choice: not set.
Embedded video
The meetups section embeds a talk hosted on Vimeo. The player loads from Vimeo when you scroll to it, with Vimeo’s “do not track” setting switched on.
Booking a call and email
“Book a call” links to Cal.com, which handles the booking under its own privacy policy. When you email us, we use your message only to reply to you.
Server logs
Our web server keeps standard access logs (IP address, time, page requested, browser) for security and troubleshooting. They are deleted after 14 days. The site is delivered through Cloudflare, which processes requests to protect and speed up the site.
Your rights
You can ask what data we hold about you, have it corrected or deleted, or object to its use, by writing to [email protected].
