Introduction

This Privacy Policy explains how the Desmos Classroom Completion Tracker Chrome extension ("Extension," "we," "our," or "us") collects, uses, and discloses information about you. The Extension is designed to help teachers track student completion rates in Desmos Classroom activities without storing or transmitting any user data outside of your browser.

Information We Collect

The Completion Tracker for Desmos does not collect, store, or transmit any personal information to external servers. Specifically:

• Student Data: The Extension analyzes student completion information that is already displayed on the Desmos Classroom summary page. This information includes student names and their activity completion status.
• Processing: All data processing occurs locally within your browser. No data is sent to our servers or any third-party services.
• Local Storage: The Extension does not store any data between sessions. All analysis results are temporary and will be lost when the popup is closed or the page is refreshed.

How We Use Information

The Extension uses the information displayed on the Desmos Classroom dashboard solely to:

• Calculate completion rates for each student
• Generate class-wide statistics (such as average completion percentage)
• Provide you with the option to export this data as a CSV file or copy it to your clipboard

All of these functions occur entirely within your browser.

Data Sharing and Disclosure

The Extension does not share any data with third parties. When you export data as a CSV file or copy data to your clipboard, this data remains on your device until you choose to share it.

Your Rights and Choices

Since the Extension does not store any data, there is no user data to access, modify, or delete. The Extension only processes data that is already visible to you on the Desmos Classroom dashboard.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by updating the "Last Updated" date at the top of this policy. We encourage you to review this Privacy Policy periodically.

Permissions Used

The Extension requires the following Chrome permissions:

• activeTab: Allows the Extension to access the current tab's content to analyze student completion data
• scripting: Allows the Extension to execute scripts on the Desmos Classroom website to gather and process completion data

These permissions are used solely for the purpose of calculating completion statistics and do not enable the collection of any data beyond what is necessary for the Extension's functionality.
