Information on copyright
A copyright infringement can only occur once you disseminate your learning contents, that is, if you create public sets of flashcards or unlock private sets of flashcards for other users. As long as you create private sets of flashcards for your own studies alone, you cannot infringe any copyrights.
As a teacher, pupil, student, or lecturer, you benefit from copyright privileges insofar as you may also disseminate in fact copyright-protected contents such as pictures or charts without approval by the author under certain conditions (cf. "Limitations on copyright in an educational environment").
The following guidelines are not exhaustive and see themselves as a basic code of good practice.
It is your own responsibility not to infringe copyright. We do not take any responsibility or liability for losses or damage resulting from copyright infringements. In case of doubt, we recommend to refer to further legal documents or a legal person.
