2. Hosting and server logs
This website is hosted by Vercel Inc. When you visit it, technically necessary data is processed - IP address, date and time, requested page, browser and operating system - to deliver the site and protect it against misuse. Legal basis: Art. 6 (1)(f) GDPR (legitimate interest in a secure, functioning website). Vercel may process data in the USA; transfers are based on the EU-US Data Privacy Framework and/or standard contractual clauses.
3. Contact form
When you send an inquiry, we process the details you provide: name, email address, and optionally phone number and company, your area of interest and your message. We use them only to handle your inquiry.
- Legal basis: Art. 6 (1)(b) GDPR (steps prior to a contract) and Art. 6 (1)(f) GDPR (answering business inquiries).
- Storage: inquiries are stored in a database operated by Neon Inc. and delivered to our inbox by Resend (email delivery).
- Retention: inquiries are deleted automatically after 12 months, unless a business relationship follows or statutory retention obligations apply.
- We do not store your IP address in plain text. For abuse protection, only a one-way hash is kept.
4. Spam and abuse protection
Forms are protected by Cloudflare Turnstile, which checks whether a request comes from a person. Turnstile processes technical information such as IP address and browser characteristics. Legal basis: Art. 6 (1)(f) GDPR (protection against automated abuse). We also apply rate limits using hashed identifiers, deleted after 24 hours.
5. Newsletter
If you subscribe to updates, we store your email address and the time and wording of your consent. Subscription uses double opt-in: you are only subscribed after confirming the link we send. Unconfirmed requests are deleted after 7 days. Legal basis: Art. 6 (1)(a) GDPR. You can withdraw consent at any time using the link in every email or by contacting us; your address is then deleted.
6. Cookies and similar technologies
This website uses only technically necessary storage. We do not use analytics or marketing trackers unless you consent. If such tools are introduced, they will only run after your consent, and your decision is recorded as proof of consent for 36 months. See the cookie policy.
