Terms of Service

Last updated 29 July 2026

By downloading, installing, or using AI Usage Monitor (“the app”), you agree to these terms. If you don't agree, don't use the app.

1. What the app is

A free, open-source macOS menu bar app that shows your Claude and ChatGPT usage limits as live percentages, reading the logins you already have.

2. Not affiliated with Anthropic or OpenAI; unofficial interface

The app is an independent project. It is not affiliated with, authorized by, endorsed by, or sponsored by Anthropic or OpenAI. “Claude”, “Claude Code”, and “Anthropic” are trademarks of Anthropic PBC; “ChatGPT”, “Codex”, and “OpenAI” are trademarks of OpenAI. Both are used only to describe what the app interoperates with.

The app reads undocumented usage endpoints and reuses the public Claude Code OAuth client id. These are unofficial, may change or break at any time, and their use could be inconsistent with either provider's terms.

3. Your responsibilities

You must have Claude Code and/or the ChatGPT app or Codex CLI installed and signed in with an account you are entitled to use.
You are responsible for your own use of your Anthropic and OpenAI accounts, including compliance with Anthropic's terms and usage policies, OpenAI's terms, and any other agreements you have with them. Using unofficial interfaces may be inconsistent with those agreements; you use the app at your own discretion and risk.

4. No warranty

The app is provided “as is” and “as available,” without warranty of any kind, express or implied, including but not limited to merchantability, fitness for a particular purpose, and non-infringement. The developer does not warrant that the app will be uninterrupted, error-free, or secure, or that it will keep working as Anthropic or OpenAI change their services. (See the Apache-2.0 LICENSE for the governing disclaimer.)

5. Limitation of liability

To the maximum extent permitted by law, the developer shall not be liable for any direct, indirect, incidental, special, consequential, or exemplary damages arising out of or related to your use of, or inability to use, the app.

6. No support obligation

This is a hobby project offered for free. There is no guarantee of support, updates, or continued availability. It may be modified or discontinued at any time.

7. License

The source code is licensed under the Apache License 2.0 (see LICENSE). These terms govern your use of the distributed application; the license governs the source code.

8. Changes

These terms may change; updates are published here with a new “last updated” date. Continued use after a change constitutes acceptance.
