Privacy policy

Last updated: November 2026. The German version is authoritative.

1. Controller

TecClean GmbH, Markus-von-Kienlin-Straße 1, 88048 Friedrichshafen, Germany. Phone +49 7544 968 98-15, email info@tecclean.de. Represented by the managing directors Christopher Braschel and Andreas Kuhn.

2. Principles

We only process personal data to the extent necessary to provide this website and handle your requests. We use cookies and scripts from Google for audience measurement only with your consent (section 5). Beyond that, this website uses no tracking or advertising cookies, no other analytics services, no embedded maps, videos or social media content, and does not load fonts or scripts from third parties, apart from the Google tag after your consent.

3. Hosting and server log files

The website is hosted by Vercel Inc., 440 N Barranca Ave #4133, Covina, CA 91723, USA. The server location is Frankfurt am Main: the request form is processed exclusively in the Frankfurt data centre region, and the pages are delivered through Vercel’s delivery network, for visitors from Germany and Europe generally from locations within the European Union as well, in particular Frankfurt. When you visit, the host processes technically necessary data (IP address, date and time, requested address, browser and operating system, referrer) in server log files, which are kept only for a short time, in order to deliver the website securely and reliably. The legal basis is Art. 6(1)(f) GDPR. A data processing agreement is in place with Vercel. Where Vercel, as a company based in the USA, accesses data, for example for administration and troubleshooting, this is based on the EU-US Data Privacy Framework or standard contractual clauses.

4. Request form and contact

If you contact us via the form, by email or by phone, we process your details (for example salutation, name, company, email, phone, country, information on the testing task and uploaded documents) to handle your request and prepare a quotation. The legal basis is Art. 6(1)(b) GDPR (pre-contractual measures) and Art. 6(1)(f) GDPR. Details are checked on the server; to prevent abuse we limit the number of requests per sender and use an invisible check field instead of a captcha service. Data is transferred encrypted (TLS) between your browser and our server. Uploaded files, including pasted screenshots, are checked for permitted file types and size. Your request is delivered as an email to our mailbox; for this we use Microsoft 365 provided by Microsoft Ireland Operations Ltd., One Microsoft Place, South County Business Park, Leopardstown, Dublin 18, Ireland, under a data processing agreement with data stored in the EU. Your details and files are not stored permanently on our web server. If the address through which you reached our website contains a click identifier from a Google ad (gclid) or campaign parameters, we include these details in your request without storing them in your browser, so that we can attribute requests to our ads (Art. 6(1)(f) GDPR).

5. Google Analytics 4 (audience measurement, only with your consent)

With your consent we use Google Analytics 4 provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland, to understand how our website is used: pages viewed, time on site, source of the visit, device and browser and the approximate location. Google Analytics sets cookies (for example _ga and _ga_…, lifetime up to two years) and processes the IP address only to determine the location, without storing it. Events such as submitting the request form are passed to Google Ads through the link between Google Analytics and our Google Ads account in order to measure the effectiveness of our ads. Without your consent Google Analytics is not loaded. User and event data are deleted according to the retention period set in Google Analytics, at the latest after 14 months. The legal basis is your consent under Art. 6(1)(a) GDPR and Section 25(1) TDDDG; you can change or withdraw it at any time via “Cookie settings” in the footer. Data may be transferred to Google LLC in the USA; Google is certified under the EU-US Data Privacy Framework. Further information: policies.google.com/privacy.

6. Retention

We delete requests once they have been dealt with and no statutory retention obligations apply. If a request leads to an order, the retention periods under commercial and tax law apply.

7. Further analyses through a partner laboratory

If further analyses (for example SEM/EDX or FTIR) are coordinated through an accredited partner laboratory, we only pass on the information required for the order, after agreement with you.

8. Your rights

You have the right of access, rectification, erasure, restriction of processing, data portability and objection to processing based on Art. 6(1)(f) GDPR. You can lodge a complaint with a data protection supervisory authority, for example the State Commissioner for Data Protection and Freedom of Information of Baden-Württemberg.

9. Encryption

This website uses TLS encryption (HTTPS).
