I use Hotjar in order to better understand users’ needs and to optimize the experience. This technology service helps me to better understand my users’ experience (e.g. how much time they spend on which pages, which links they choose to click, what users do and don’t like, etc.) and this enables me to build and maintain this website. Hotjar uses cookies and other technologies to collect data on our users’ behavior and their devices. This includes a device's IP address (processed during your session and stored in a de-identified form), device screen size, device type (unique device identifiers), browser information, geographic location (country only). Hotjar stores this information on our behalf in a pseudonymized user profile. Hotjar is contractually forbidden to sell any of the data collected on our behalf. For further details, please see the ‘about Hotjar’ section of Hotjar’s support site.
