+
+
+## Data Collection & Confidentiality

+
+The content you created inside the app includes any text, recording, photos you upload and their derivations.
+They will be stored securely at HKUST and will only be used for purposes of this study. The personal identifiers are stripped from them (i.e., the data is anonymized). They are accessible and only accessible by:
+1. The researchers involved in this research project
+2. Other participants of this study (only accessible through the app)
+
+The results of this research may be presented at conferences or published in academic journals. For report purpose, a selected subset of the user-created content may be displayed to the public in academic papers as a part of the report. The researchers will *not* obtain additional approval from the users before adding their content to academic publications.

+
+### "Other" data
+

+
+
+## Risk and Discomfort
+
+Participants may experience unexpected harassment or offend if some other participants do not follow the rules and post inappropriate content on the platform. The current application, as a prototype and proof-of-concept, does not have any content moderation. However, the researchers have zero tolerance with inappropriate content, and will help mitigating the discomform by
+* listen and respond to participants' report of inappropriate content idenitified in this application
+* delete confirmed inappropriate content
+* if necessary, disqualify the participant that posts the confirmed inappropriate content
+* if participants appeal to the university for investigation, coorperate the university in investigating the inappropriate content
