Hi Abubaker,
I am unfamiliar with REDCap Survey Software.
Our
free IAT solution is a standalone solution that will record the data to the OSF. It is possible to
launch it with a participant ID, and it is also possible to redirect the participant back to a different platform at the end.
Regarding privacy, the only identifying information is what you collect (and then save on the OSF) in your study. If you redirect participants from a different platform, using a participant ID, the ID will be saved with the rest of the data on the OSF.
To redirect participants at the end, you can browse the
Prolific example. The relevant code is in lines 108-112 and 140 in the
mgr.js file.
All the best,
Yoav
