2. Principles

This website uses no cookies, no analytics or tracking tools and loads no third-party content (e.g. fonts, maps, videos or social media plugins). We only process personal data to the extent necessary to operate the website or to answer your enquiry.

3. Hosting and server log files

This website is hosted by IONOS SE, Elgendorfer Str. 57, 56410 Montabaur, Germany. A data processing agreement pursuant to Art. 28 GDPR is in place with IONOS.

When you visit the website, the web server automatically records technical data: IP address, date and time of access, page requested, amount of data transferred, referrer URL, browser type and operating system. This data is technically required to deliver the website and keep it secure (legal basis: Art. 6(1)(f) GDPR). IONOS deletes or anonymises the log files after a short period; the data is not combined with other sources.

4. Contact form and email

If you contact us via the contact form or by email, we process your name, email address and message in order to answer your enquiry. Form data is sent to us by email and not stored in a database. The legal basis is Art. 6(1)(b) GDPR where your enquiry relates to a contract or pre-contractual measures, otherwise Art. 6(1)(a) GDPR (consent) or Art. 6(1)(f) GDPR (legitimate interest in answering enquiries). The data is deleted once your enquiry has been fully dealt with, unless statutory retention obligations apply. You may withdraw your consent at any time with effect for the future.

5. TLS encryption

This website uses TLS encryption for security. You can recognise an encrypted connection by “https://” in your browser's address bar.

6. Your rights

You have the right of access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and to object to processing based on Art. 6(1)(f) GDPR (Art. 21). Simply contact us at the address above.

You also have the right to lodge a complaint with a data protection supervisory authority. The competent authority is: Die Landesbeauftragte für den Datenschutz Niedersachsen, Prinzenstraße 5, 30159 Hannover, Germany.

7. Apps

Separate privacy notices apply to our apps (Tavo, Cockpit One) and will be published with each app.
