Data protection declaration

Thank you for visiting our website. The protection of personal data and therefore your privacy is of great relevance to Ziemann Holvrieka. Please find information below on how we use and protect your data. It goes without saying that Ziemann Holvrieka complies with all legal data protection regulations. Please bear in mind that data transmission over the Internet can be subject to security vulnerabilities. Complete protection against access by third parties is not possible.

Access data

You can visit our website without providing any personal information. The website provider collects data about accesses to the site and saves them as “server log files”. The following data are logged in this way: visited website, time of access, amount of data sent in bytes, source/reference from which you accessed the site, browser used, operating system used, IP address used.
The data collected are used solely for statistical evaluations and to improve the website. However, the website provider reserves the right to subsequently check the server log files if there are concrete indications of illegal use. These data will only be passed on to third parties if required to do so by law or if a court decision orders their disclosure. They are not passed on for commercial or non-commercial purposes.

Data collection and data processing for contract closure

We collect and process your personal data which you voluntarily provide for the purpose of contacting us (e.g. for registration, via contact form or by e-mail) or to fulfil and process our contractual obligations and to respond to your enquiries. For purposes of contract fulfilment, your data may be passed on to service providers commissioned by us, e.g. to suppliers and logistics companies. After contract fulfilment, your data will be blocked for further use and deleted after expiry of the retention periods under tax and commercial law, unless you expressly agree to further data use, as described below:

This website uses the “Google Analytics” service, which is provided by Google Inc. (1600 Amphitheatre Parkway Mountain View, CA 94043, USA) for analysis of website usage by users. The service uses “cookies” – text files which are stored on your device. The information collected by the cookies is usually sent to and stored on a Google server in the USA.

Google Tag Manager

This website uses Google Tag Manager. This enables us as the website operator to manage website tags. These tags are JavaScript and/or html code building blocks that can be used to trigger or provide additional functions on our website. In particular, we use these building blocks to enable web analytics services (such as Google Analytics) that record the arrival, behaviour, visit duration and website abandonment of users. Details of the web analytics services used on our website are specified above. Google Tag Manager manages these tags and activates them during interaction with the user. The collection, storage and processing of personal data is only carried out through the corresponding web analytics services and not Google Tag Manager itself. If a web analytics service is disabled by the user, Google Tag Manager will also be unable to activate the service.

The right to objection

You can object to the processing of your personal data at any time without giving reasons. If you make use of this or do not make your data available, the contract cannot be fulfilled. If we process your data to protect legitimate interests, you may object to such processing for reasons arising from your particular situation. We will then no longer process your personal data unless we can prove compelling reasons worthy of protection for the processing which outweigh your interests, rights and fundamental freedoms or the processing serves to assert, exercise or defend legal claims (Art. 6 para. 1 lit. f GDPR).
