Collection and processing of personal data

Collection and processing of personal data

The use of our website is usually possible without providing personal information. Personal information refers to all information about your identity, such as your name, e-mail address and postal address. Unless you have agreed otherwise with LIQVIS, we collect only basic personal information that is necessary for our business relationship such as your name, job title, address, telephone number, e-mail address and other contact information. Such data will only be collected if you provide it to LIQVIS, for example when you order informational materials, subscribe to an e-mail information service, apply for a job online or participate in a survey or a competition. LIQVIS collects this data only directly from you and not from other third parties.

Use and disclosure of personal information

LIQVIS uses your personal information to respond to your request, process your order or give you access to special information or offers you have requested from us. For example, if you fill out an online contact form, LIQVIS will use that information to contact you regarding your interest in our services.

If necessary, LIQVIS also uses personal data of its customers and data of participants for marketing purposes if they have expressly consented to this. In this case, LIQVIS will use the contact information you provide to discuss your interest in our services and to provide you with information about the company, its subsidiaries and partner companies including promotions or events. For this purpose, it may also be necessary for LIQVIS to pass on your data to companies within the group or external service providers as part of contract data processing. For example, it may be necessary for LIQVIS to pass on customer data for Customer Relationship Management purposes.

LIQVIS will not sell your personal data or otherwise market or pass it on to third parties for their advertising purposes. If you have expressly given your consent for this, LIQVIS will share your information with its subsidiaries and partner companies so that they can contact you directly.

In principle, LIQVIS will process your data only within the European Union. Data transfers to third countries shall only occur as part of the administration of IT systems in accordance with the provisions on contract processing and only if a) the transmission is generally admissible and b) the special conditions for transmission to a third country are met; in particular, the data importer shall ensure an adequate level of data protection in accordance with EU standard contractual clauses for the transfer of personal data to processors within the context of contract processing in third countries. This is based on the provisions of the Federal Data Protection Act and the German Telemedia Act.

Information on web analysis

Google Analytics

Use of your IP address

Computers and devices connected to the Internet are assigned a unique number that is called their IP address. Because these numbers are typically assigned in country-based blocks, an IP address can often be used to identify the country (province or city) that connects to the Internet via this computer. Google Analytics captures the IP addresses of website visitors. This allows website owners to analyse which parts of the world their visitors come from. This method is known as geotargeting of IP addresses.

Google Analytics will not pass on the actual IP address information to its customers. In addition, it masks IP addresses – website owners who use Google Analytics can set it so that instead of the entire IP address, only part of it is used for geotargeting. Website owners generally have access to the IP addresses of their website visitors, regardless of the use of Google Analytics.
