Privacy Policy

Last updated: October 2026

We take the protection of your personal data seriously. This policy explains which personal data we process when you visit our website, contact us, request brochures or subscribe to our newsletter, for what purposes, on which legal basis, and what rights you have under the EU General Data Protection Regulation (GDPR).

1. Controller

ColVisTec AG
Max-Planck-Str. 3

Phone: +49 30 6392 7816
E-mail: info@colvistec.de
Represented by the Management Board: Jan H. Johnsen (CEO)

For all questions about data protection, please contact us at the address above or at info@colvistec.de.

2. Visiting our website (server log files)

When you visit our website, your browser automatically transmits information to our web server, which is stored temporarily in log files: IP address of the requesting device, date and time of access, the page or file requested, the website from which you reached us (referrer), browser type and version, and operating system.

This data is processed to deliver the website, to ensure its stability and security, and to detect and defend against attacks. The legal basis is Art. 6(1)(f) GDPR; our legitimate interest lies in the secure and error-free operation of the website. The log data is deleted after a short period unless it is needed longer to investigate a specific security incident.

Our website is hosted by IONOS SE, Elgendorfer Str. 57, 56410 Montabaur, Germany, which processes the data on our behalf under a data processing agreement pursuant to Art. 28 GDPR.

3. Cookies, analytics and tracking

Our website does not use analytics, tracking or marketing tools, and does not set cookies for such purposes. If technically necessary cookies are used (for example to keep the website working correctly during your visit), they are used on the basis of § 25(2) No. 2 of the German Telecommunications Digital Services Data Protection Act (TDDDG) and Art. 6(1)(f) GDPR and do not require your consent.

The fonts used on this website are loaded from our own server. No connection to third-party servers (for example Google) is established for this purpose.

The forms for brochure requests and newsletter subscription are also loaded from our own server. Data is only transmitted to our newsletter service provider CleverReach (see section 5) when you submit a form.

For the tracking that may be used in our newsletter e-mails, see section 5.3.

4. Contacting us by e-mail or phone

If you contact us by e-mail or phone, we process the data you provide (for example name, company, e-mail address, phone number and the content of your enquiry) in order to answer your request.

The legal basis is Art. 6(1)(b) GDPR if your enquiry relates to a contract or to pre-contractual measures (for example a quote or a trial), and otherwise Art. 6(1)(f) GDPR, our legitimate interest being to respond to enquiries addressed to us.

We use Microsoft 365, a service of Microsoft Ireland Operations Ltd., One Microsoft Place, South County Business Park, Leopardstown, Dublin 18, Ireland, for our e-mail communication. Microsoft processes the data on our behalf under a data processing agreement (Art. 28 GDPR). A transfer of data to Microsoft Corporation in the USA cannot be excluded; Microsoft is certified under the EU-U.S. Data Privacy Framework, for which the European Commission has adopted an adequacy decision (Art. 45 GDPR). In addition, the EU Standard Contractual Clauses are part of the agreement.

We delete your data once your enquiry has been fully dealt with and it is no longer needed, unless statutory retention obligations apply (in particular under commercial and tax law, generally 6 or 10 years for business correspondence).

5. Brochure requests and newsletter

On our website you can request brochures about our products and subscribe to our monthly newsletter. For both, we use the e-mail marketing service CleverReach, provided by CleverReach GmbH & Co. KG, Schafjückenweg 2, 26180 Rastede, Germany. CleverReach processes the data on our behalf under a data processing agreement pursuant to Art. 28 GDPR and stores it on servers in the European Union. Further information is available in CleverReach's privacy policy: www.cleverreach.com/de-de/datenschutz/.

5.1 Double opt-in and proof of your request

After you submit a form, you will receive an e-mail asking you to confirm your e-mail address (double opt-in). This ensures that nobody can register with someone else's e-mail address. Your request is only processed once you have confirmed it.

To be able to prove your request and your consent, we log the time of registration and confirmation and the IP address used. The legal basis is Art. 6(1)(c) GDPR in conjunction with Art. 7(1) GDPR (obligation to demonstrate consent) and Art. 6(1)(f) GDPR, our legitimate interest being the legally compliant sending of e-mails.

5.2 Brochure requests

When you request brochures, we process your e-mail address, first name (optional), last name, company and the brochures you have selected, in order to provide you with the requested information material. The legal basis is Art. 6(1)(b) GDPR, as you are requesting information about our products.

We may also use this data to contact you once by e-mail or phone about your interest in our products. The legal basis is Art. 6(1)(f) GDPR; our legitimate interest lies in following up on enquiries about our products. You can object to this at any time (see section 8).

A brochure request does not subscribe you to our newsletter unless you explicitly tick the corresponding box. We delete the data from your brochure request once it is no longer needed for the purposes described above, unless statutory retention obligations apply.

5.3 Newsletter

If you subscribe to our newsletter, we use your e-mail address and, if provided, your name and company to send you our monthly newsletter with selected news from our industry and information about ColVisTec. The legal basis is your consent pursuant to Art. 6(1)(a) GDPR.

Our newsletter e-mails contain technologies that allow us to see whether an e-mail has been opened and which links have been clicked. We use this information to improve our newsletter. This analysis is covered by your consent to receive the newsletter (Art. 6(1)(a) GDPR). If you do not want this analysis, you can unsubscribe from the newsletter at any time.

You can withdraw your consent at any time with effect for the future, using the unsubscribe link at the end of every newsletter or by sending an e-mail to info@colvistec.de. The withdrawal does not affect the lawfulness of the processing carried out before it.

We store your data for as long as you are subscribed to the newsletter. After you unsubscribe, your data is deleted. We may keep your e-mail address in a blocklist to ensure that you do not receive any further newsletters; the legal basis for this is Art. 6(1)(f) GDPR, our legitimate interest being to respect your decision permanently.

6. Links to other websites

Our website contains links to external websites, for example to our LinkedIn company page. These are simple links; no data is transmitted to the operator of the linked website until you click on the link. After that, the privacy policy of the respective provider applies.

7. Encryption

This website uses TLS/SSL encryption. You can recognise an encrypted connection by "https://" in the address bar and the lock symbol in your browser.

8. Your rights

Under the GDPR you have the following rights with regard to your personal data:

Right of access (Art. 15 GDPR)
Right to rectification (Art. 16 GDPR)
Right to erasure (Art. 17 GDPR)
Right to restriction of processing (Art. 18 GDPR)
Right to data portability (Art. 20 GDPR)
Right to withdraw any consent given, for example to receive our newsletter, with effect for the future (Art. 7(3) GDPR)

Right to object (Art. 21 GDPR): Where we process your data on the basis of Art. 6(1)(f) GDPR, you have the right to object to this processing at any time on grounds relating to your particular situation. We will then no longer process the data unless we can demonstrate compelling legitimate grounds, or the processing serves the establishment, exercise or defence of legal claims. Where we use your data for direct marketing, you can object at any time without giving reasons.

To exercise your rights, an informal message to info@colvistec.de is sufficient.

Right to lodge a complaint: You also have the right to lodge a complaint with a data protection supervisory authority. The authority responsible for us is:
Berliner Beauftragte für Datenschutz und Informationsfreiheit
Alt-Moabit 59–61, 10555 Berlin, Germany
www.datenschutz-berlin.de

9. Automated decision-making

We do not use automated decision-making or profiling within the meaning of Art. 22 GDPR.

10. Changes to this policy

We will update this privacy policy if our website or the legal requirements change. The current version is always available on this page.
