Ratings on your Prolific screen

As you browse Prolific, the extension reads the study pages you open and shows the matching Prolific Tea rating inline, so you can spot a researcher's reputation before you start their study. Click any study to jump straight to that researcher's profile on Prolific Tea.

It never logs into Prolific, never changes the page, and makes no requests to Prolific on its own. It only observes the data your own browsing already loads.

When you opt in, the extension helps build the shared directory by:

• automatically listing researchers and their studies on Prolific Tea: rewards, completion times, outcomes, and study & researcher IDs;
• filling in and verifying missing details on reviews you've already written, so your history stays accurate without manual edits.

Big institutions like cornell.edupost studies under several different Prolific accounts. Without real data it's impossible to tell which account is which, or to group them correctly. The community data the extension gathers is what lets Prolific Tea tell a genuine institution apart from one person, and show the right researcher behind each study.

Only the Prolific study pages you actually open:

• your available study list, and
• your submission history.

From those it keeps only lightweight study facts: title, researcher/study IDs, reward, estimated and actual time, and the outcome. The study description and everything else are dropped before anything is sent.

• Your name, email, or any personal identifier.
• Your Prolific participant ID: it is never read, stored, or transmitted.
• Your Prolific password or session: the extension never signs in for you.
• Anything from pages outside Prolific.

The study data is linked only to your Prolific Tea account, so it can repair your own reviews, nothing else.

The first time you open the extension it asks before sharing anything. Sharing is opt-in, and you can turn “List researchers from the studies you see” on or off anytime from the extension's settings. With it off, the extension still shows you ratings; it just contributes nothing to the directory.
