Privacy Policy — Codex Quota Monitor

Overview

Codex Quota Monitor is a browser extension that displays your Codex usage quota directly in the browser toolbar.

        🔒 We do not collect, transmit, or store any personal data on external servers. Everything stays on your device.
      

🔓 This extension is open source. You can inspect every line of code at github.com/codexquotamonitor/codex-quota-monitor and verify our privacy practices yourself.

What data is accessed

The extension reads the following data exclusively from ChatGPT's own usage endpoint, using your existing authenticated browser session:

Your current Codex usage limits
Session quota usage percentage and reset time (5-hour window)
Weekly quota usage percentage and reset time (7-day window)
Any extra Codex credits available beyond your plan limits
Your account plan type (e.g. Pro)

This data is stored locally on your device using the browser's built-in chrome.storage.local API and is never sent anywhere else.

What we do not do

We do not collect any personally identifiable information
We do not transmit any data to external servers
We do not use analytics, tracking pixels, or telemetry
We do not share data with third parties
We do not read your conversations or any Codex content
We do not store data beyond what is necessary to display your quota

Permissions explained

storage — saves quota data locally on your device
tabs — opens chatgpt.com when you click the "View quota" button

Third-party services

The extension does not integrate with any third-party services, SDKs, or APIs other than ChatGPT's own usage endpoint, which you are already authenticated with.

The public website uses Google Analytics to measure aggregate traffic. This analytics applies to the website only, not to the browser extension.
