Privacy Policy

Summary

Saar processes all data locally inside your browser. No text, tokens, costs, or usage data are ever transmitted to any server operated by this extension.

What data is processed

Saar intercepts the SSE response stream from claude.ai to read token counts and model information returned by Anthropic's servers. This data is:

• Counted locally using a BPE tokenizer bundled inside the extension.
• Stored temporarily in chrome.storage.session, scoped to your current browser session. It is cleared when the browser closes.
• Never sent to any external server, analytics service, or third party.

What data is not collected

• The content of your messages or Claude's responses is never read or stored.
• No account information, cookies, or authentication tokens are accessed.
• No personally identifiable information is collected.
• No usage analytics or telemetry are sent anywhere.

Permissions used

• storage — stores per-session token counts locally in your browser.
• tabs — identifies which tab a token count belongs to so session totals stay per-tab.
• scripting — injects the stream interceptor into claude.ai at page load.
• alarms — schedules periodic cleanup of stale session data for closed tabs.
• unlimitedStorage — allows the extension to store session data without Chrome's default quota limits.
• sidePanel — enables the side panel UI showing session history and cost totals.
• optional host permission: https://claude.ai/* — requested at runtime when you first enable the extension. Required to observe the SSE stream on that domain.

Third-party services

Saar does not integrate with any third-party analytics, advertising, or data collection service. The BPE tokenizer vocabulary (claude.json) is bundled inside the extension and does not make network requests.

Feedback submissions (optional): The side panel includes a voluntary feedback form. If you choose to submit feedback, your typed message and the extension version number are sent to Formspree (formspree.io), a third-party form processing service. No other data is included. Submission is entirely opt-in and requires an explicit click. Formspree's privacy policy is at formspree.io/legal/privacy-policy.
