Hi! I built an automatic gatekeeper called LongiGate. This toolkit consists of a few functions you can insert into your experiment.js script for subject ID and time detection, with repeated-attempt blocking, built for longitudinal online studies.

This toolkit ensures:
Subject access is only granted at the correct session time, and they are allowed to open the link several times without being marked as "returned".
Repeated or invalid attempts (e.g., due to refresh) are blocked
Time-based access is coordinated across JavaScript (frontend) and Python (backend)
