X X Thread Reader
Privacy first by design
Privacy policy

Your thread data stays in your browser.

X Thread Reader is designed as a local-first browser extension. This page explains what website content the extension handles, why it needs its permissions, and how that data is limited to the extension's single purpose.

Effective date: April 2, 2026 Applies to the extension and this website

Privacy overview

X Thread Reader accesses the X/Twitter page you are already viewing in order to extract the current thread and export it as Markdown for your own reading, notes, or archives.

X Thread Reader does not operate a remote parsing service, does not require an account, and does not upload extracted thread content to our own servers as part of normal use.

Single purpose

The extension has one primary purpose: when you actively trigger it on an X/Twitter post page, it extracts the current thread and converts it into Markdown that you can copy or download locally.

What data the extension handles

  • The currently active X/Twitter tab when you trigger extraction.
  • Website content visible on that thread page, including post text and image links needed for export.
  • Your browser clipboard only when you choose the copy action.

Why the permissions are used

  • `activeTab`: used only after you click the extension so it can read the current tab and extract the thread you asked for.
  • `x.com` and `twitter.com` host access: used only so the extension can operate on X/Twitter thread pages where extraction is supported.

How data is used

Website content accessed by X Thread Reader is used only to perform the extraction and Markdown export that you requested. We do not use that content for advertising, profiling, unrelated analytics, or resale.

What we do not collect or sell

  • No account registration details.
  • No saved thread history on our servers.
  • No analytics tied to the content of the threads you export.
  • No sale of personal data or website content.
  • No use of extracted content for advertising or data brokerage.

How exports are handled

When you copy Markdown or download a `.md` file, that output is created locally in your browser session. Where the file goes after that depends on your own device, browser, or note-taking workflow.

Data sharing and transfer

Under normal use, extracted thread content is not transferred to our servers. We do not sell or transfer that content to third parties for purposes unrelated to the extension's single purpose.

Retention

Because extraction happens locally, thread content is only handled within your browser session unless you explicitly choose to copy or download the result yourself.

Website analytics

This marketing site is currently built as a static site. If analytics are added later, they should be privacy-conscious, minimal, and should not collect the content of exported threads. If that changes, this page should be updated.

Chrome Web Store policy alignment

The use of data accessed by X Thread Reader is intended to comply with the Chrome Web Store User Data Policy, including the Limited Use requirements, for the extension's disclosed single purpose.

Changes to this policy

If the extension adds a cloud feature, account system, server-side processing, or broader analytics in the future, this privacy policy must be updated before those changes go live.
