GLM Usage Monitor (“the extension”) shows your Z.AI / ZHIPU (BigModel) GLM Coding Plan usage in your browser toolbar. This policy explains what the extension handles and where it goes.
The extension asks you to paste your own GLM Coding Plan API key (the token you already use to authenticate GLM API requests). Entering it is optional and purely for your own use.
All of this is kept only on your device, in the browser’s local extension storage (chrome.storage.local). It never leaves your machine except to authenticate the requests described below.
The extension makes read-only GET requests to the official monitor endpoints of your chosen provider to fetch your own usage:
https://api.z.ai/api/monitor/usage/...https://open.bigmodel.cn/api/monitor/usage/...The only data sent on those requests is your API key, in an Authorization header, solely so the provider can identify your account. Your data is never sent to any other server, third party, analytics service, or advertising network. The extension contains no tracking, telemetry, or ads.
storage — save your key, settings, and cached usage locally on your device.alarms — poll the usage API on a timer (default every 5 minutes) so the toolbar badge and popup stay current.host_permissions for the monitor endpoints — fetch your own usage from the official GLM monitor API using your stored key. The extension requests the specific monitor paths, not broad host access.The only third party that receives any data is the GLM provider you selected (Z.AI and/or ZHIPU/BigModel), and only the key needed to authenticate your own usage requests. The extension is not affiliated with or endorsed by those providers.
Your key is stored locally and transmitted only over HTTPS to the provider’s official endpoints. Treat your Coding Plan key as a secret; do not paste a key into a copy of this extension you did not obtain from a trusted source.
No selling or sharing of data, no building of profiles, no email/SMS, no access to your browsing history, no access to the content of any website you visit.
If this policy changes, the updated version will ship with the extension and be dated above.
