2. Hosting and technical delivery

This website is hosted through ChatGPT Sites. The service is provided in the European Economic Area by OpenAI Ireland Limited, 1st Floor, The Liffey Trust Centre, 117–126 Sheriff Street Upper, Dublin 1, D01 YC43, Ireland. OpenAI processes technical data required to deliver, secure and operate the website. This may include IP address, date and time of access, requested page, browser and device information, and technical log data.

The legal basis is Article 6(1)(f) GDPR. The legitimate interest is the secure and reliable operation of this website. More information is available in OpenAI’s European Privacy Policy.

3. Sites analytics

ChatGPT Sites records website traffic automatically and provides aggregated statistics such as unique visitors and page views over time. No separate analytics SDK has been added to this website. The legal basis is Article 6(1)(f) GDPR. The legitimate interest is understanding the reach and technical use of the website.

4. Heyflow enquiry form

The enquiry form is provided as an embedded Heyflow by Heyflow GmbH, Jungfernstieg 49, 20354 Hamburg, Germany. To make the enquiry form available without a long wait, the Heyflow widget is prepared shortly after the visible website has finished loading. Technical connection data may therefore be sent to Heyflow even if you do not open the form. Information entered in the form is processed to respond to your enquiry, prepare a possible project and communicate through your selected contact channel.

The legal basis is Article 6(1)(b) GDPR for steps taken at your request before entering into a contract and Article 6(1)(f) GDPR for efficient enquiry handling. Required fields are marked in the form; all other information is voluntary. Data is retained only as long as needed for the enquiry, a resulting business relationship, or applicable legal obligations. See Heyflow’s Privacy Policy for further information.

5. Affiliate link

The Heyflow offer links to a referral URL hosted at heyflow.cello.so for Heyflow. When you follow that link, the referral identifier is included in the destination URL and the destination providers receive the usual connection data. If you register or become a paying customer through the link, the referral may be attributed to me and I may receive a commission. The subscription itself is concluded directly with Heyflow.

Following the link is voluntary. The legal basis for providing and measuring the referral is Article 6(1)(f) GDPR. The legitimate interest is transparent referral marketing and attribution.

6. External links

This website links to LinkedIn, Fiverr and Heyflow. Data is transferred to those providers only when you open the respective external link. Their own privacy policies then apply.

7. Your rights

Subject to the applicable legal requirements, you have the right to access, correct, erase or restrict the processing of your personal data, to data portability, and to object to processing based on legitimate interests. You also have the right to lodge a complaint with a data protection supervisory authority.

For questions or to exercise your rights, contact gino.business@buchheims.de.
