Privacy

This page explains which personal data is processed when you visit www.headindata.com.

Who is responsible?

The controller within the meaning of the EU General Data Protection Regulation (GDPR) is Florian Roscheck, c/o Postflex #3711, Emsdettener Str. 10, 48268 Greven, Germany, e-mail hello@headindata.com.

What happens when you visit this website?

This website consists of static pages. It sets no cookies, has no forms and no user accounts.

The pages are delivered by Cloudflare, Inc., 101 Townsend St, San Francisco, CA 94107, USA. To deliver a page, Cloudflare’s servers process technical data that your browser sends: your IP address, the date and time of the request, the page requested, the browser type and version, the operating system and the page you came from. This is needed to show you the website and to keep it stable and secure. The legal basis is Article 6 (1) (f) GDPR, the legitimate interest in running a reliable website. Cloudflare processes this data on my behalf under a data processing agreement and may process it in the USA; the transfer is covered by the EU-U.S. Data Privacy Framework and standard contractual clauses.

Are visits counted?

If visits are counted, this is done with Cloudflare Web Analytics. It works without cookies, stores nothing on your device and does not build a profile of you. It shows me, for example, how many people opened a page and from which country. The legal basis is Article 6 (1) (f) GDPR, the legitimate interest in understanding which content is useful.

Videos

A video on this site is loaded only after you click on it. Until then, no data goes to the video platform. When you click, the video is loaded from YouTube (Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland) in its privacy-enhanced mode, and YouTube receives your IP address and information about your browser. Google’s privacy policy applies to that processing.

This site links to other websites, such as LinkedIn, YouTube, Instagram, TikTok, GitHub, Medium and SlideShare. When you follow a link, the privacy policy of that website applies.

When you write to me

When you send me an e-mail, I process your address and the content of your message to answer you. The legal basis is Article 6 (1) (f) GDPR, or Article 6 (1) (b) GDPR if your message is about an engagement such as a talk. I delete the correspondence when it is no longer needed, unless the law requires me to keep it.

Your rights

You have the right to access your data, to have it corrected or deleted, to restrict its processing, to object to its processing and to receive it in a portable format. To use these rights, write to hello@headindata.com. You also have the right to lodge a complaint with a data protection supervisory authority.
