Is Claude Usage Tracker safe?

Medium risk

Claude Usage Tracker stores Claude prompt and request details in local debug logs whenever it runs.

The extension forces debug mode on and records intercepted Claude request URLs and request bodies in browser local storage. These logs can include prompt content, form input, and some fetched document text, with each entry truncated and retained in a bounded debug log.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.
