The Scope, Objectives, and Legal Basis for Data Processing

As we enable contact through a contact form, online chat, or brief on the website, we process your personal data: name, email address, website address, phone number, company information, and enquiry content.

Providing personal data is voluntary but necessary for the performance of a contract to which the data subject is a party, or to take action at the request of the data subject before entering into a contract. In the case of a planned change in the purpose of processing, we always ask the data owner for consent and inform about the changing conditions of data processing.
