As a sole freelancer, I am not required to appoint a Data Protection Officer.
This website is hosted on Amazon Web Services (AWS) and delivered via Amazon CloudFront (content delivery network) from an Amazon S3 bucket. AWS acts as a processor on my behalf under a data processing agreement.
The distribution is restricted to CloudFront edge locations within the European Union, the United States, and Canada.
When you visit this website, your browser necessarily transmits technical information such as your IP address, browser type, operating system, requested URL, and the date and time of access in order to deliver the website.
According to my configuration, server-side access logging is disabled. I do not receive or retain visitor IP addresses or request logs from CloudFront.
Legal basis: Art. 6(1)(f) GDPR (legitimate interest in the secure and reliable provision of this website).
This website uses the typefaces Instrument Sans, Space Grotesk, and IBM Plex Mono from Google Fonts.
These fonts are not loaded automatically. On your first visit, you are asked whether you consent to loading them from Google's servers.
Only if you actively consent, your browser connects directly to:
These services are operated by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland, and/or Google LLC, United States.
As a result, your IP address and browser information are transmitted to Google. This may involve a transfer of personal data to the United States. Information about Google's processing of personal data is available in Google's Privacy Policy.
Legal basis: Art. 6(1)(a) GDPR (your consent).
If you decline, or take no action, Google Fonts are never requested and the website uses your device's default fonts instead.
Your choice is stored only in your browser's local storage under the key pf-font-consent so that you are not asked again on the same device and browser. This storage is used solely to remember your preference and does not itself require separate consent.
You may withdraw your consent at any time by clearing this website's local storage in your browser. Withdrawal does not affect the lawfulness of processing carried out before withdrawal.
If you contact me by email, I process the personal data you provide (such as your name, email address, and message) solely to respond to your inquiry.
Legal basis:
Correspondence is retained only for as long as necessary to process your request, maintain any resulting business relationship, or comply with statutory retention obligations under German tax and commercial law.
The "Schedule a call" / "Let's talk" links on this website lead to an external scheduling service (currently cal.eu).
No personal data is transmitted to that provider unless you actively click the link and interact with their website. Once you leave this website, the privacy policy of the external provider applies.
Personal data is disclosed only where necessary for operating this website or responding to inquiries.
Depending on the circumstances, recipients may include:
No personal data is sold or shared for advertising purposes.
Some service providers may process personal data outside the European Economic Area (EEA), particularly in the United States.
Where such transfers occur, they are based on appropriate safeguards in accordance with Chapter V GDPR, such as the European Commission's Standard Contractual Clauses or another valid transfer mechanism.
This website does not use cookies for analytics, advertising, or marketing purposes.
The only browser storage used is local storage to remember your Google Fonts preference. No tracking profiles are created.
