Usability
Interface 
User-friendliness/complexity of the tool´s interface
Straightforward, intuitive.
Time efficiency Time needed for mastering the „how-to“ of the tool and a production of a task
High. CamStudio has a moderate learning curve for beginners, but it is generally time-efficient. In this sense, it is similar to other tools such as Audacity.

English
Respect for privacy Does the tool require registration? Who can see my data? Can I remain anonymous?
High. CamStudio requires installation but not creating a user account, so data collection is minimal. As a desktop application, user data is stored on the user’s local device rather than a third party service. CamStudio.org protects all online visitor data against unauthorised access, and it does not sell, trade, or give personal information to other companies or organisations. It does not state compliance with the GDPR. See more here.

Yes.
Tailorability (If so, how?) Possibility of the tool to be used for a range of different activities (e.g. to what extent you can organize a project assignment with a central activity based on this tool)
Yes, users can record content for whichever purpose.
