Privacy Policy

1. General

The protection of your personal data is of particular concern to us. We therefore process your data exclusively on the basis of statutory provisions (Swiss DPA, GDPR where applicable). In this privacy policy, we inform you about the most important aspects of data processing on our website.

3. Collection and Processing of Personal Data

When you visit our website, technical access data is automatically collected (e.g. IP address, time of access, page visited). This data is used exclusively to ensure trouble-free operation and to improve our services. It is not possible for us to identify you personally from this data.

If you send us enquiries via the contact form, your details including the contact data you provide will be stored for the purpose of processing the enquiry and in case of follow-up questions.

4. Cookies

Our website uses cookies. These are small text files stored on your device. Some cookies are technically necessary (e.g. session cookies), others are used to analyse user behaviour (e.g. Google Analytics). Technically necessary cookies are set on the basis of our legitimate interest. Analytics cookies are only activated with your consent.

5. Analytics Tools

We may use web analytics services to statistically evaluate the use of our website. The data collected is processed anonymously or pseudonymously. The legal basis for this is your consent.

Own cookie-free audience measurement

In addition, we measure the use of our website with our own solution that runs on our own server at our hosting provider. No cookies are set, no persistent local browser storage is used and no data is passed on to third parties. We record: pages viewed, time on page and scroll depth, clicks on phone, email, WhatsApp and appointment links, starting and submitting forms, the origin of the visit (referring website, search engine or AI assistant and campaign parameters such as utm_source), the device type (mobile, tablet, desktop) and the language version.

Your IP address is not stored. To count unique visitors, we create a non-reversible hash from IP address, browser identifier and date that changes daily; recognising you across several days is therefore not possible. A random session identifier is kept only in your browser’s session storage and is deleted when you close the tab. If you send us an enquiry, we link it to this session identifier to understand which pages lead to enquiries. Raw data is deleted after 13 months. The legal basis is our legitimate interest in a data-minimising evaluation and improvement of our services.

OpenAI Measurement Pixel and Conversions API (advertising in ChatGPT)

We run ads in ChatGPT. To measure whether an ad led to a visit or an enquiry, we use the Measurement Pixel and the Conversions API of OpenAI (OpenAI OpCo, LLC, San Francisco, USA). The pixel loads a script from OpenAI and sets two cookies: “__oppref” stores a click identifier if you arrive via a ChatGPT ad (30 days), “__obref” a random browser identifier for our website (365 days). We transmit page views, clicks on phone, email, WhatsApp and appointment links, starting forms and – only after we have stored your enquiry – a confirmation with a random enquiry identifier. The pixel also matches entries in form fields (email address, first and last name) automatically by converting them into a non-reversible hash in your browser before sending them to OpenAI. If you send us an enquiry, our server additionally transmits your email address, phone number and name only as a non-reversible hash (SHA-256), plus your IP address and browser identifier, so that OpenAI can attribute the enquiry to an ad. Data may be transferred to the USA. If “Do Not Track” or “Global Privacy Control” is enabled in your browser, we do not load the pixel and do not send enquiries to OpenAI. The pixel is never loaded in internal areas (client portal, admin, login). The legal basis is our legitimate interest in measuring our advertising; you can object by enabling the settings mentioned or blocking cookies. More information: openai.com/policies/privacy-policy.

6. Your Rights

You have the right to access, rectification, deletion and restriction of processing of your stored personal data. You also have the right to lodge a complaint with the competent supervisory authority.

To exercise your rights, please contact: hello@dlm-digital.ch

7. SSL Encryption

This site uses SSL encryption for security reasons. You can recognise an encrypted connection by the fact that the address line of your browser changes from "http://" to "https://" and by the lock symbol in your browser bar.

8. Changes to this Privacy Policy

We reserve the right to amend this privacy policy so that it always complies with current legal requirements or to implement changes to our services. The new privacy policy will then apply to your next visit.
