Partial Consent - A Study on User Preference for Informed Consent.

This study evaluates the use, acceptance and desirability of consenting with partial consent. For this purpose, an app was developed that requested access permissions to various data for different tasks. The user had the means to limit the exposure of personal data by opting an additional Maybe - button other than the usual binary (allow/deny) options. Upon expiration of time-bound partial consent, the user could potentially reassess the trade-off between service and privacy consequences. Partial consent was only used by one fifth of the participants, whereby just under half of the participants stated after completing the questionnaire that they would like to use it on their private devices.
