Privacy Policy

Overview

AI Token & Cost Tracker is a browser extension that counts tokens and estimates cost for your ChatGPT conversations. It was built to run entirely client-side: there is no backend server operated by the developer, no account system, and no analytics or advertising SDK bundled into the extension.

This policy explains, plainly, what the extension can see, what it stores, and where that data goes.

Information we don't collect

We do not collect, transmit, or have access to your conversations, prompts, model responses, account information, or usage statistics. The extension has no server to send data to, so none of this information ever leaves your browser through any mechanism we control.

Information stored locally

To do its job, the extension reads the text and model name of conversations open in your ChatGPT tabs, and keeps a small amount of derived data in chrome.storage.local — a storage area private to your browser profile:

Token counts, model, and estimated cost for the conversation currently open
A rolling history of daily totals (tokens and cost) so the popup can show a 7-day chart
Your settings — theme, whether the floating badge is shown, and your daily token budget

None of this is readable by websites, by other extensions, or by us. You can clear all of it at any time with the Reset All Data button in the extension's Settings panel, and it is deleted automatically if you uninstall the extension.

Permissions we request, and why

storage

Save your settings and stats locally. Backs everything described above in "Information stored locally" — nothing about this permission allows data to leave your device.

activeTab

Let the toolbar icon talk to the current tab when you open the popup, without requesting broader access to every open tab.

host_permissions
chatgpt.com
chat.openai.com

Read conversation content only on these two domains, so token counts can be computed. The extension cannot read or run on any other website.

Third-party services

The extension's popup and on-page badge load their typeface (Inter and JetBrains Mono) from Google Fonts (fonts.googleapis.com), the same way most websites do. Loading a font this way sends a request to Google's servers containing standard web request metadata (like IP address), governed by Google's privacy policy. No conversation content or usage data is included in that request.

Aside from that, and the extension's own requests to ChatGPT's own servers (using your existing, authenticated session — the same requests your browser already makes to display the page) to read conversation content, the extension makes no other network requests.

Children's privacy

This extension is not directed at children and does not knowingly collect information from anyone, of any age — see "Information we don't collect" above.

Changes to this policy

If this policy changes, the updated version will be published at this same address with a revised effective date above. Continued use of the extension after a change constitutes acceptance of the revised policy.
