Respect for privacy
Does the tool require registration? Who can see my data? Can I remain anonymous?
Medium/High. It requires setting up a very basic profile with name, age and location. Unfortunately, there is no privacy section in the app, but since it is supported by Google Apps, the usual policies apply. This means that Google apps collect personal data, which may later be shared with third parties. See more here. The European Centre for Modern Languages does not monetise or sell user data and uses Google services only for operational purposes.
Saving work for future use
Possiblity to save your or others´ work for reuse/reproduction
Yes.
Tailorability (If so, how?)
