2. The short version

This website is a plain information site. No cookies are set, no analytics or tracking services are embedded, and no data is passed on to advertising networks. The fonts are hosted locally on the server, so no connection to Google servers takes place. Personal data is only processed if you contact us yourself.

3. Hosting and server log files

This website is hosted by Infomaniak Network SA, Rue Eugene-Marziano 25, 1227 Les Acacias (Geneva), Switzerland. When the site is accessed, the host automatically processes technically necessary data (for example IP address, date and time of access, page requested, browser type) in order to deliver the website and ensure secure operation. The legal basis is Art. 6 (1) (f) GDPR (legitimate interest in secure and stable operation). The servers are located in Switzerland, for which the European Commission has issued an adequacy decision (Art. 45 GDPR). A data processing agreement pursuant to Art. 28 GDPR has been concluded with the host.

4. Contact form

The contact form on this site does not transmit any data to a server. Your entries are assembled into an email inside your browser only, which then opens in your own email program. Your details reach us as an ordinary email only once you click send there.

The data transmitted in this way (name, company, email address, content of the message) is stored in order to process your enquiry and answer follow-up questions. The legal basis is Art. 6 (1) (b) GDPR (steps prior to entering into a contract, or performance of a contract) and Art. 6 (1) (f) GDPR (legitimate interest in responding to enquiries).

5. Project documents

In the course of an enquiry or an assignment you may send your own documents, such as specifications, drawings, measurement data or samples. These are used solely to process your enquiry and carry out the assignment, are not passed on to third parties and are not published. On request, a separate non-disclosure agreement is concluded before confidential information is exchanged.

6. Retention

Personal data is deleted as soon as the purpose of processing no longer applies and no statutory retention periods prevent deletion (for example under tax and commercial law, up to 10 years for invoicing records).

7. Your rights

• Access to your stored data (Art. 15 GDPR)
• Rectification of inaccurate data (Art. 16 GDPR)
• Erasure (Art. 17 GDPR) and restriction of processing (Art. 18 GDPR)
• Data portability (Art. 20 GDPR)
• Objection to processing based on legitimate interests (Art. 21 GDPR)
• Complaint to a supervisory authority (Art. 77 GDPR); the authority of your place of residence or the Bavarian Data Protection Authority (BayLDA) is competent

An informal email to the address above is sufficient to exercise your rights.

8. Obligation to provide data

You are under no legal or contractual obligation to provide data. However, without the details required for an enquiry it cannot be processed.

9. Language

This is a translation for convenience. In case of doubt, the German version applies.
