PurpleSensor — CGM Sensor Integrity Analysis

What is this?

PurpleSensor analyzes your CGM export file for sensor integrity issues — anomalous reading clusters that can trigger false alarms or, worse, missed ones. The same engine that runs here is open source and available on GitHub for anyone who wants to inspect the code.

Upload your data file below. Your file is processed and immediately deleted. No glucose values are stored. Only anonymized aggregate statistics are retained to build the public performance dataset.
