Privacy Policy

Effective date: February 8, 2026

      TL;DR — This extension processes everything locally on your device. No data is collected, stored, transmitted, or shared with anyone.
    

1. What This Extension Does

Twitter/X to Markdown is a browser extension that reads publicly visible tweet text and conversation threads from Twitter/X pages and converts them into Markdown format. All processing happens entirely within your browser.

2. Data We Collect

None. This extension does not collect, store, or transmit any data whatsoever. Specifically:

No personally identifiable information
No authentication credentials or tokens
No browsing history or web activity
No analytics, telemetry, or usage tracking
No cookies or local storage data

3. Data We Access

When you click the extension and initiate a scrape, the extension reads the following from the currently active Twitter/X page:

Tweet text content
Display names and usernames (public profile information)
Timestamps
Engagement metrics (likes, reposts, etc.)
Media indicators (whether a tweet contains photos or videos)

This information is read from the page DOM, converted to Markdown, and presented to you within the extension popup. It is never sent to any server, API, or third party.

4. How Data Is Processed

All data processing occurs locally in your browser using JavaScript. The generated Markdown is either copied to your clipboard or downloaded as a .md file — both actions happen entirely on your device.

5. Third-Party Services

This extension does not use any third-party services, analytics platforms, remote APIs, or external scripts. No remote code is loaded or executed.

6. Permissions Explained

activeTab — Allows the extension to access the currently open Twitter/X tab when you click the extension icon.
scripting — Used as a fallback to inject the content script if it hasn't loaded on an already-open Twitter tab.
Host permissions (twitter.com, x.com, mobile.twitter.com) — Required for the content script to run on Twitter/X pages. No other websites are accessed.

7. Data Sharing

We do not sell, transfer, or share any user data with any third party for any reason, including advertising, analytics, or creditworthiness assessment.

8. Children's Privacy

This extension does not knowingly collect any information from anyone, including children under the age of 13.

9. Changes to This Policy

If this privacy policy is updated, the changes will be posted on this page with a revised effective date. Since the extension collects no data, material changes are unlikely.

10. Contact

If you have questions about this privacy policy, please open an issue on the GitHub repository or reach out via the extension's Chrome Web Store listing.
