1Introduction

marked.sh ("we", "our", or "the extension") is a Chrome browser extension that helps you organize and manage your X.com (formerly Twitter) bookmarks using AI-powered features.

This Privacy Policy explains how marked.sh handles your information. The short version: we don't collect, store, or have access to your personal data. Everything happens locally on your device.

2Data We Do NOT Collect

marked.sh is designed with privacy as a fundamental principle. We do not:

  • Collect your X.com bookmarks or any bookmark content
  • Store any data on our servers (we don't have data servers)
  • Track your browsing activity or behavior
  • Use cookies for tracking or advertising
  • Collect personal information like your name, email, or X.com credentials
  • Share or sell any data to third parties
  • Access your AI conversations or queries
  • Collect analytics about how you use the extension

3How Your Data is Stored

All data processed by marked.sh is stored locally in your browser using standard browser storage mechanisms:

  • Chrome Local Storage: Your bookmarks, categories, tags, and preferences are stored in your browser's local storage
  • IndexedDB: Larger datasets like bookmark content may be stored in IndexedDB for better performance
  • No Cloud Sync: Data never leaves your device unless you explicitly export it

This means your data is only accessible on the device where you installed the extension. If you uninstall the extension or clear your browser data, your marked.sh data will be deleted.

4AI Features and Third-Party Services

marked.sh offers AI-powered features like auto-categorization and the "Ask AI" chat feature. Here's how these work:

  • Your API Keys: You provide your own API keys for Claude (Anthropic) or Grok (xAI). We never see or store these keys on any server—they're stored locally in your browser.
  • Direct Communication: When you use AI features, your browser communicates directly with the AI provider (Anthropic or xAI). We don't proxy these requests.
  • Provider Privacy Policies: Your interactions with AI providers are subject to their respective privacy policies:

5X.com Integration

marked.sh integrates with X.com to sync your bookmarks:

  • How Syncing Works: The extension reads your bookmarks directly from X.com's interface in your browser. We don't use X.com's API or access your X.com account credentials.
  • What We Access: Only publicly visible bookmark data that you've already saved on X.com.
  • No Account Access: We cannot post, like, retweet, or perform any actions on your X.com account.

6Data Export and Deletion

You have complete control over your data:

  • Export: You can export all your data as JSON at any time from the extension settings
  • Delete: Uninstalling the extension or clearing browser data removes all marked.sh data
  • No Recovery: Since we don't store your data, we cannot recover it if deleted

7Browser Permissions

marked.sh requests the following Chrome permissions:

  • Access to x.com: Required to read your bookmarks from X.com
  • Storage: Required to save your bookmarks and preferences locally

We only request permissions that are strictly necessary for the extension to function.

8Children's Privacy

marked.sh is not intended for use by children under 13 years of age. We do not knowingly collect any information from children. Since we don't collect any personal information from any users, this policy applies universally.

9Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated "Last updated" date. We encourage you to review this policy periodically.

If we make significant changes to how we handle your data (though given our privacy-first approach, this is unlikely), we will notify users through the extension.
