Key terms

To ensure our privacy policy is legible and understandable we first explain the terminology used.

Personal data

Personal data means any information relating to an identified or identifiable natural person. An identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person.

Processing data

Processing is any operation or set of operations performed on personal data or on sets of personal data, whether or not by automated means, such as collection, recording, organisation, structuring, storage, adaptation or alteration, retrieval, consultation, use, disclosure by transmission, dissemination or otherwise making available, alignment or combination, restriction, erasure or destruction.


Cookies are pieces of text that are stored by an Internet browser upon the request of a website you visit. Many cookies contain unique identifiers consisting of a character string assigned by the Internet page (or server) you visit. This allows them to differentiate your individual browser from other Internet browsers that contain other cookies. Thus, in subsequent visits and requests, a specific Internet browser can be recognized and identified using the unique identifier in a cookie.

You may, at any time, delete already set cookies, prevent the setting of cookies temporarily or permanently through our website by a corresponding setting in the Internet browser you use. Deactivating the setting of cookies in the Internet browser may render certain functions of our websites entirely unusable (e.g. logging in to our services, using a shopping cart, etc.) as every visit is considered your first visit.

IP address

Every device connected to the Internet is assigned a number known as an Internet protocol (IP) address. These numbers are usually assigned in geographic blocks. An IP address may be used to identify the approximate location from which a device is connecting to the Internet.

What data we collect and why

The processing of personal data, such as your name, address, email address, or phone number is always in line with the General Data Protection Regulation (GDPR), and in accordance with the Luxembourgish data protection regulations.

Things you create or provide to us

When you create an account or choose to submit a request through email, a contact or feedback form you may provide us with personal information – like your name, email address, phone number, password, etc. We also collect the content you create, upload or choose to share using one of our services.

Information we collect as you use our services

We gather usage and behaviour statistics and information about the browsers and devices you use to improve our content strategy. In addition, to maintain the accessibility and technical stability of our software, we monitor and identify code errors and collect meta data for diagnostic purposes.

Information we collect include the device type, brand, operating system, browser version, IP address of the device as well as information that helps to identify the app's state in which an unexpected error may have occurred.

The legal basis of the aforementioned data processing is Art. 6(1) f) of the GDPR. The information is collected anonymously, is not used for personal reasons, and is retained for a limited time. Such processing is in our legitimate interest because the data is used solely for analysing and improving our content structure and code quality.

By default, we do not keep permanent IP address logs. However, IP address logs may be kept temporarily to combat abuse and fraud, and your IP address may be retained permanently if you are engaged in activities like spamming, DDoS attacks against our infrastructure, brute force attacks, etc. The legal basis of this processing is our legitimate interest to protect our service against nefarious activities.

Information we collect as you enter into a contract with us

We collect and store contractual and pre-contractual information necessary to fulfil your request. This includes personal identification information of the contractual partner.

Information we collect to comply with legal obligations

We collect and store information to be able to comply with legal obligations (including those imposed by virtue of applicable commercial, tax and anti-money laundering laws) as well as any regulatory obligations and to respond to requests and comply with requirements from public authorities.
