By default, the only review information displayed on the Public profile is the name of the journal or conference you reviewed for and the number of reviews you have added and verified on Publons for each journal/conference. Below is an example of how your verified review records are displayed on your Public profile by default:
A reviewer can edit the review display policy for his/her reviews to deviate from this default policy e.g. to publish the title of the article they reviewed or publish the content of the review (after the manuscript is published). You can find more information about your review display preferences here: What are my review display preferences?
Journals can also set permissions to specify exactly what information reviewers can publicly display about a review. The review display policy set by the journal overrides the review display preferences set by the reviewer.
No matter what privacy settings are in place, we never display information about the manuscript until the manuscript has been published.
