Hi Chris (and all), Due to ethical considerations, I need to store personal data from my participants (e.g., email) in a separate file. I have tried to add a new app at the end of my experiment, but if I download the full dataset I am still able to identify my participants. Is there another way to do this? Thanks in advance for your help! Anabela

The only way to have two separate data sets from the very beginning is to use two separate servers: On the first server, you collect the experimental data. You then forward a participant identifier (e.g., oTree’s participant code and/or participant label) to the second server — and, for convenience, the associated remuneration if the remuneration is choice-dependent. On the second server, you host a survey to collect the personal data. The survey can be programmed in oTree, but it could also be, for instance, a Qualtrics survey.

Thanks so much, I will try this approach!

Why can't you just write it to a file, e.g., using Python's csv module while setting the database fields to an empty string? This could be done in before_next_page.
