Liability for content: As a service provider, I am responsible for my own content on these pages in accordance with general laws. However, I am not obliged to monitor transmitted or stored third-party information or to investigate circumstances indicating illegal activity. Obligations to remove or block the use of information under general laws remain unaffected. Liability in this respect is only possible from the point in time at which a specific infringement becomes known. Upon becoming aware of any such legal infringements, I will remove the relevant content immediately.

Liability for links: The navigation on this website links to other web presences that I also operate and control myself (e.g. developer portfolio, online shop). Should this website in future contain links to external third-party websites over whose content I have no influence, I cannot accept any liability for that content. The respective provider or operator of the linked pages is always responsible for their content. At the time of linking, no legal violations would be apparent. A permanent content review of linked pages is not reasonable without concrete evidence of a legal infringement. Upon becoming aware of any legal infringements, I will remove such links immediately.

The content and works created by the site operator on these pages are subject to German copyright law. The reproduction, processing, distribution, or any form of exploitation beyond the limits of copyright law requires the prior written consent of the respective author or creator.

Insofar as content on this website was not created by the site operator, the copyrights of third parties are respected.

As a sole operator without staff processing personal data, I am not obliged to appoint a data protection officer.

This website is hosted by Vercel Inc., 340 S Lemon Ave #4133, Walnut, CA 91789, USA (“Vercel”). The personal data collected on this website is stored on Vercel’s servers. This may include IP addresses, contact requests, meta and communication data, website access and other data generated via a website.

The hoster is used on the basis of Art. 6 para. 1 lit. f GDPR. I have a legitimate interest in the most reliable and secure presentation of my website. A data processing agreement pursuant to Art. 28 GDPR has been concluded with Vercel.

As Vercel is based in the USA, data may be transferred to and processed in a third country. This transfer is based on the European Commission’s Standard Contractual Clauses (Art. 46 para. 2 lit. c GDPR), which Vercel has committed to as part of its data processing agreement.

The provider of the pages automatically collects and stores information in so-called server log files, which your browser automatically transmits. These are:

• Browser type and browser version
• Operating system used
• Referrer URL
• Host name of the accessing computer
• Time of the server request
• IP address

This data is not merged with other data sources. The collection of this data is based on Art. 6 para. 1 lit. f GDPR. The website operator has a legitimate interest in the technically error-free presentation and optimisation of the website.

Server log files are stored for a maximum of 7 days and are then automatically deleted.

If you contact me by e-mail, the data you provide (in particular your e-mail address and the content of your message) will be stored in order to process your enquiry.

The processing is based on Art. 6 para. 1 lit. b GDPR if your request is related to the performance of a contract or pre-contractual measures. In all other cases, the processing is based on my legitimate interest in the effective processing of enquiries (Art. 6 para. 1 lit. f GDPR).

The data will be deleted once the purpose of the storage no longer applies or you request deletion, unless statutory retention periods apply.

My e-mail mailbox is provided by IONOS SE, Elgendorfer Straße 57, 56410 Montabaur, Germany. As an EU-based processor, IONOS processes e-mails on my behalf on the basis of a data processing agreement pursuant to Art. 28 GDPR.
