Privacy Policy

1. What data the extension collects

Claude Usage Tracker reads and stores usage data that is already visible to you on your claude.ai account's usage page (claude.ai/settings/usage). This includes:

• Subscription plan name (e.g. "Pro", "Max")
• Quota usage counts and percentages (e.g. "15 of 45 messages")
• Progress bar values from the usage page
• Reset timing information shown on the page
• Raw text sections from the page for debugging purposes

The extension does not access your conversations, messages, prompts, files, billing information, or any other account data beyond the usage page.

2. Where data is stored

All collected data is stored exclusively in chrome.storage.local — a sandboxed browser storage mechanism that is:

• Local to your device and Chrome profile
• Not synced to Google's servers (unlike chrome.storage.sync)
• Accessible only to this extension
• Deleted when you uninstall the extension

The extension retains up to 1500 snapshots (approximately 15 days at 15-minute capture intervals). Older snapshots are automatically deleted to stay within this limit.

3. Data transmission

The extension makes zero network requests to any server operated by us or any third party.

The only network activity performed by the extension is:

• Opening https://claude.ai/settings/usage in a background tab to read your usage data — the same page you can visit manually

No usage data, telemetry, crash reports, analytics events, or personal information is ever sent anywhere.

4. Permissions used

• storage — to save snapshots locally via chrome.storage.local
• alarms — to schedule periodic background captures
• notifications — to show an optional capture confirmation notification (disabled by default)
• tabs — to open claude.ai/settings/usage for data capture and to allow manual navigation
• host permission: https://claude.ai/* — to inject the content script that reads the usage page

No other permissions are requested. No broad host permissions (<all_urls>) are used.

5. Third-party services

This extension does not integrate with any third-party analytics, advertising, crash-reporting, or data-processing services.

This extension is not affiliated with, endorsed by, or sponsored by Anthropic, PBC.

6. Children's privacy

This extension does not knowingly collect any information from users under 13 years of age, nor is it directed at children.

7. Changes to this policy

If the privacy practices of this extension change materially, we will update this document and bump the "Last updated" date above. Continued use of the extension after changes constitutes acceptance of the updated policy.
