Prolific Shield: Auto-reject & Screen-out protection

About

Protect Your Prolific Account from Speeding Warnings and Auto-Rejections — Giving you your control back.

Prolific Shield is an essential companion tool for Prolific participants. Designed to protect your prolific submissions and ultimately helping to protect against account suspensions. Prolific Shield helps you avoid auto-rejections, speeding warnings, and automatic screen-out submissions which lead to former. 

Key Features
- Estimated Completion Timer
Prolific Shield reads the estimated completion time directly from the Prolific study page and sets up a countdown. It helps you pace your submission so you never submit a study too quickly.

- Smart Auto-Start & Auto-Stop 
When enabled, the timer automatically starts when you click "Start study" and stops when you navigate back to your Prolific studies dashboard.

- Submission Protection
Prevents researchers from automatically submitting completion codes back to Prolific if you get screened out or if you complete a task "too quickly".

- Submission Log & Completion Codes
If a study tries to submit a code automatically, Prolific shield intercepts it, blocks the automatic submission, and saves the completion code in your logs. Once the timer reaches a safe duration, you can copy the code from the log and submit it manually.

- Side Panel Integration 
Keep the timer visible alongside your study window. Configure the extension to open in Chrome's side panel by default for a clean, non-obtrusive workspace.

Why Do You Need Prolific Defender?
Avoid "Speeding" Rejections: 
Submitting studies faster than the minimum threshold set by researchers can lead to automated rejections and speed warnings. The built-in countdown keeps you aware of elapsed time.

Defend Against Screen-outs: 
Some studies screen you out but attempt to submit a completion code anyway, which can flag your account for submitting invalid data. Prolific Shield blocks these automatic redirects.

Manual Control: You decide exactly when a study is marked as complete.
