AI Spend Lens — Privacy Policy

Last updated: 6 July 2026

AI Spend Lens does not collect, transmit, or sell any of your data. Everything the extension measures stays on your own computer. There is no account, no server, and no tracking.

What the extension does

AI Spend Lens shows an estimated token count and approximate API-equivalent cost for your conversations on Claude, ChatGPT, and Gemini, and lets you shorten a draft prompt with the “Shrink” button. It runs entirely inside your browser.

Information we collect

None that leaves your device. To display your usage totals, the extension reads the visible text of the AI page you are on to estimate a token count, and stores the running totals locally using your browser’s chrome.storage.local.

  • We do not read, store, or transmit the content of your conversations.
  • We do not use analytics, cookies, or fingerprinting.
  • We do not send any data to us or to any third party.

Where your data lives

Your daily and weekly totals — and, if you tap the “Pro” interest button, a simple local click count — are saved only in your browser’s local storage. Clearing the extension’s storage or removing the extension deletes them permanently. This data never reaches a network.

Permissions we request

  • storage — to remember your usage totals between sessions, on your device only.
  • Site access to claude.ai, chatgpt.com, and gemini.google.com — so the on-page badge can estimate tokens for the conversation you are viewing.

Cost figures are estimates

Token counts are approximated from on-screen text and priced against public API rates. They are a rough guide, not a bill, and are shown for your own reference only.

Changes

If this policy changes, the “Last updated” date above will change with it. Continued use after an update means you accept the revised policy.
