Privacy Policy

Ration — AI Quota Tracker · Last updated: August 2026

Ration collects no data. It has no backend, no analytics, no accounts, and no telemetry of any kind. Nothing you do ever leaves your browser.

What Ration does

Ration is a browser extension that displays the remaining usage quota of the AI subscription services you choose to enable (for example Claude and Codex/ChatGPT). To do this, it calls the same internal usage endpoint each provider's own settings page uses, from your browser, using the login session you already have with that provider.

Data collection: none

• Ration transmits no data to its developer or to any third party.
• There is no analytics SDK, no error-reporting service, no remote configuration, and no runtime dependency of any kind.
• The only network requests Ration makes are to the provider sites you explicitly enable, solely to read your quota.

What is stored, and where

• Your latest quota readings and your provider on/off settings are stored locally in your browser (chrome.storage.local). They are never synced or uploaded.
• The Clear all data button in the popup permanently deletes everything Ration has stored.

Credentials

• Ration never reads, stores, or transmits your passwords, cookies, or tokens. It does not request the cookies browser permission.
• Requests to provider sites rely on the browser attaching your existing session automatically — the same way the provider's own settings page works. Where a provider's web app uses a short-lived session token, Ration obtains it from that provider's own session endpoint at the moment of the request, uses it in memory once, and never persists it.

Permissions

• storage — to keep your readings and settings on your device.
• alarms — to refresh quota readings on a schedule (every 5 minutes per enabled provider).
• Provider site access (e.g. claude.ai, chatgpt.com, cursor.com) — optional, requested only when you switch that provider on, and used solely to read your quota from that provider.
• declarativeNetRequestWithHostAccess — some providers' APIs (Cursor) reject requests unless the Origin header is the provider's own site; while such a provider is enabled, one rule sets that header on Ration's own read-only usage requests to that provider. The rule is scoped to Ration's own requests on sites you granted — it never touches any other page's traffic.
