The public-facing brand name is Andermatt Design. The legal entity responsible for data processing is P. Heiniger Design.
The processing of personal data on this website is based on the Swiss Federal Act on Data Protection (revDSG/nDSG, in force 1 September 2023). Where users from the European Union or EEA interact with this website, the General Data Protection Regulation (GDPR) may additionally apply.
Data is processed on the following legal bases as applicable: performance of a contract or pre-contractual measures (Art. 6(1)(b) GDPR / Vertragserfüllung nach nDSG), legitimate interests in operating the website and responding to inquiries (Art. 6(1)(f) GDPR / berechtigte Interessen nach nDSG), compliance with legal obligations, and consent where explicitly given.
When you visit this website, the web hosting infrastructure (Vercel) automatically records access data, including IP address, browser type, operating system, referrer URL, pages visited, and timestamp. These logs serve technical operation and security purposes. They are typically retained for a short period as determined by the hosting provider.
When you submit the contact form, we collect your name, email address, and message. This data is used exclusively to respond to your inquiry. Depending on configuration, submissions may be stored in a Google Sheets spreadsheet and a notification sent via Resend email service.
This website includes a multi-step diagnostic conversation flow. When you complete and submit this form, the following data may be collected and processed:
This data is used to prepare for and conduct the requested conversation. Depending on configuration, it is stored in Google Sheets and a notification is sent via Resend. Submission is subject to your explicit consent via the checkbox in the form.
If you contact us by email, the content of your message and your email address (and any other data you provide) are stored for the purpose of handling your request. We do not pass this data to third parties unless required by law or necessary for the performance of a contract.
When you book a discovery call via the calendar link, you interact with Google Calendar (Google LLC). Your name, email address, and selected appointment time are shared with Google. The data processing is governed by Google's privacy policy.
At present, no newsletter or marketing email service is operated. If this changes in future, this privacy policy will be updated accordingly.

Where P. Heiniger Design processes personal data on behalf of a client within a project (e.g. hosting a client's contact forms or managing a client's customer data), a separate data processing agreement (DPA/AVV) may be concluded with that client. This governs the respective roles and responsibilities under applicable data protection law.

Fonts: This site uses the Inter typeface, which is self-hosted and served directly from our hosting infrastructure (Vercel). No request is made to Google Fonts or any external font CDN. No IP address is transmitted to third parties for typography.

Personal data is retained only as long as necessary for the stated purpose or as required by applicable law:
We take reasonable technical and organisational measures to protect personal data against unauthorised access, loss, or misuse. Data transmission between your browser and this website is encrypted via HTTPS/TLS. We cannot guarantee absolute security against all possible threats.
In the course of project work, the Provider uses AI-assisted tools including ChatGPT (OpenAI), Claude (Anthropic), and Gemini (Google) as workflow aids — for example for drafting, ideation, research, and analysis. These tools are used as creative and technical support; all AI-generated output is reviewed and validated by the Provider before use. AI-generated content is never delivered directly to clients without human review.
Personal or confidential client data is not shared with AI tools unless this is appropriate for the project scope and subject to confidentiality and applicable data protection requirements. Where client data may be involved, details can be agreed in the individual project agreement.
Each AI provider processes data subject to its own privacy policy and terms of service. Providers: OpenAI (ChatGPT) · Anthropic (Claude) · Google (Gemini)
