DataPipe is a free service provided by the developers of jsPsych. We do not have a dedicated support team, but we do our best to respond to questions and issues.
We ask that if you have a question or issue, you first check the GitHub repository issues to see if your question has already been answered. If not, we encourage you to post a new issue there.
If you need to contact us directly, you can email Josh de Leeuw at jdeleeuw@vassar.edu.
