Data Privacy: You need to know two things about the Piazza company and its use of your personal data.

  • Piazza is in the United States. All their information about you, what things you read and what you post, are held in the US and are not subject to UK or EU data protection regulations. My impression is that Piazza do generally work in line with those regulations, but they are not required to do so. In particular, if the Piazza services is sold to another company then your personal data will be part of that sale.

  • Piazza is funded by the money it gets from companies who employ graduates and wish to target students for recruitment. You’ll see this when “Piazza Careers” suggests companies where you might apply for work. What’s less obvious is that Piazza will also send companies information about students or groups of students. Read their “playbook” for examples of how this works:

    You can control access to this by selecting the padlock icon on the top right of your Piazza profile.

    With Piazza, every student you hire has a high probability of having a Piazza account. And we have rich information on our students – which classes they’ve taken, which classes they’ve TA’d, and which classes they’ve received professor endorsements in. We’re able to provide you with a list of academic traits for any of your past interns or recent grads.

    Say Shelby was that star intern; just pop her name into the Find Students Similar To feature and see a list of her traits – she’s a top student in Machine Learning, a TA to an algorithms class, a college-level varsity athlete, coding since the age of 13, and a top student in at least 5 classes. Now I run a search by selecting the traits that I care most about, and within seconds, I find hundreds more like her.
