Privacy Policy

Last updated: April 14, 2026

1. Data Collection

The "Superpower for Claude" Chrome Extension is primarily a client-side application. We do not automatically collect, store, or transmit your personal information, chat content, or browsing history.

2. Data Storage

All user data generated by the extension (such as saved prompts, saved chains, queued messages, chat notes, and settings preferences) is stored locally on your device using the browser's chrome.storage.local and chrome.storage.sync capabilities. This data may be synced across your own devices if you have Chrome Sync enabled, but it is not accessible to the developer.

3. Website Interactions

The extension interacts with claude.ai to provide features such as Prompt Optimization, Usage Counter, and Message Queueing. These interactions occur strictly within your browser using your existing claude.ai session.

• Prompt Optimization: Your prompt is temporarily copied to a new background tab within your browser session to generate an optimized version. It is never sent to any external server owned by the developer.
• Usage Counter: The extension reads your usage data from Claude's own API locally within your browser session to display your current usage. No usage data is collected or transmitted externally.
• Message Queue: The extension monitors Claude's streaming state locally to detect when a response has finished generating, so it can automatically send the next queued message. No network data is collected or transmitted externally.
• Chat Export: The extension reads conversation data from Claude's own API to enable PDF and Markdown export. All processing happens locally in your browser.

4. Permissions

The extension requests the following browser permissions:

• storage: To save your settings, prompts, chains, and preferences locally.
• activeTab / tabs: To interact with the claude.ai tab and manage background tabs for prompt optimization.
• scripting: To inject interface enhancements into the claude.ai page.
• debugger: To generate PDF exports via Chrome's built-in print-to-PDF capability.
• alarms: To schedule periodic license validation checks.

5. Premium Licensing (Pro Features)

If you choose to activate a premium license key, the extension communicates with LemonSqueezy (a third-party payment and licensing platform) to validate your license. This involves sending your license key to api.lemonsqueezy.com for activation, periodic validation, and deactivation. This communication only occurs if you voluntarily enter a license key. No personal payment information is handled by the extension itself — all purchases are processed directly by LemonSqueezy through their website.

6. Bug Reporting & Feature Proposals

The extension provides "Report a Bug" and "Propose a Feature" buttons that open Google Forms.

• Report a Bug: Automatically pre-fills your Extension Version and User Agent (browser/OS details) into the form URL.
• Propose a Feature: Automatically pre-fills your Extension Version into the form URL.
• Voluntary Submission: This data is only transmitted to Google Forms if you manually click "Submit." Simply opening the form does not send any data to the developer.
• Purpose: This information is used solely for troubleshooting bugs and prioritizing feature development.

7. Uninstall Feedback

When the extension is uninstalled, your browser may open a feedback form. No personal information is automatically included in the URL. Submitting the form is entirely voluntary.

8. Third-Party Services

This extension enhances the user interface of Claude by Anthropic. It is not affiliated with Anthropic, PBC. The extension functions by injecting custom interface elements, managing local storage for organization, and automating specific user actions on the Claude website. The following third-party services are used:

• Claude (claude.ai): The target website the extension enhances. All page interactions occur locally in your browser.
• LemonSqueezy (api.lemonsqueezy.com): License key validation for optional premium features, as described in Section 5. Only contacted when a license key is provided.

9. Data Management & Liability

The extension interacts with the Claude web interface to provide features such as prompt optimization, message queueing, chat export, usage tracking, and prompt/chain libraries. While we strive for reliability, the software is provided "as is." The developer is not responsible for any data loss, unintended modifications, or disruption of functionality caused by network errors, changes to the Claude user interface, browser updates, or user error.

10. Contact

If you have questions about this policy, please contact the developer via the support email listed on the Chrome Web Store.
