Your texts will be transfered encrypted and not be stored. Only in the case of a PDF analysis the PDF file is stored temporarily (2h for downloading). If you use the "Safe & Share"-function your texts are stored permanently.
For machine learning anonymous text statistics will be stored. These are data such as character count, frequency of some characters (e.g. E 64 times) and the calculated similarity value. Based on the data no conclusions can be drawn on your person or the texts content.
