Privacy policy
The security of your data matters to us. We treat personal data confidentially and in line with the GDPR.
Hosting and content delivery networks (CDN)
This website is hosted by Vercel (Vercel Inc., San Francisco). Personal data collected on this website is processed on Vercel's servers. This includes IP addresses, metadata, and communication data. Processing is based on Art. 6 (1) (f) GDPR (legitimate interest in a secure and fast online service).
Contact by email
If you email office@gerdewal.de, we process the details you send in order to handle the enquiry (Art. 6 (1) (b) GDPR). This website does not run a contact form that stores submissions on a server. Messages stay in our mailbox for as long as handling them requires.
Your rights
You may request, free of charge, information about the origin, recipients, and purpose of your stored personal data, and you may request correction or deletion. You also have the rights to restriction, portability, and objection, and you may lodge a complaint with a supervisory authority. A message to office@gerdewal.de is enough to exercise these rights.
Google Maps
Current status: this website does not embed Google Maps. The following text keeps the previous notice and applies only if the service is switched on later. We integrate map material from Google Maps (Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland). User data, in particular IP addresses and location data, is transmitted to Google servers, which may be in the United States. Use is based on our legitimate interest in making the business easy to find under Art. 6 (1) (f) GDPR. Where consent is requested, processing is based solely on Art. 6 (1) (a) GDPR.
Google Analytics
Current status: this website does not use Google Analytics. The following text keeps the previous notice and applies only if the service is later activated with consent. This website uses functions of Google Analytics (Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland). Google Analytics uses cookies. Information generated by the cookie about your use of this website is usually transmitted to a Google server in the United States and stored there. Storage of Google Analytics cookies and use of the tool are based on Art. 6 (1) (a) GDPR (consent). We use Google Analytics with IP anonymisation enabled.
AI chatbot (Anthropic API)
If you use the AI chatbot, we process the messages you enter and technical connection data (IP address, time, selected language) in order to answer your question. Purpose limitation: processing is used only to give general information about the services described on this website. The legal basis is Art. 6 (1) (b) GDPR where the enquiry is pre-contractual, otherwise Art. 6 (1) (f) GDPR. You can ignore the chat and email office@gerdewal.de instead. Transmission is encrypted with TLS (SSL). Our server route forwards the message to the API of Anthropic, PBC (USA) so a language model can draft the reply. Anthropic acts as a processor under its API terms. Under those API terms, inputs sent through the API are not used to train the models. We do not store chat transcripts permanently. Please do not enter special-category personal data or confidential customer or company data. Anthropic may process data in the United States. Where a transfer requires it, we rely on appropriate safeguards under Art. 46 GDPR (standard contractual clauses) and, where applicable, the EU-US Data Privacy Framework. We align the processing with the GDPR and European protection standards. We cannot promise that the models run exclusively on servers in the EU. Human-in-the-loop: replies are generated automatically and may be incomplete or wrong. Responsibility for the content and for strategy stays with a human. The chat is not individual advice.
