Privacy policy
Last updated 7 November 2026
Unfold Thread is a browser extension that shows the Gmail thread you have open as a dated conversation. It is built so that your email never leaves your browser. This policy covers the extension and this website.
What the extension reads
Only the email thread open on your screen in Gmail (mail.google.com), and only when you click the Unfold thread button, the toolbar icon, or press Alt+Shift+C. It reads what Gmail has already shown you. It does not use the Gmail API and never asks you to sign in.
What the extension stores
Nothing. It does not use browser storage, cookies, IndexedDB or any database. The conversation view, including anything you type into its search box, exists only while it is open. Closing it removes it from the page.
What the extension sends
Nothing. The extension makes no network requests and has no servers, analytics, crash reporting or third-party code. Remote images in emails that Gmail has not already loaded are dropped, so opening the view never triggers a tracking image. When you open an attachment, your browser opens Gmail's own link for that file, exactly as clicking it in Gmail would.
Permissions
- Access to mail.google.com, so it can read the open thread when you ask.
- activeTab and scripting, so the toolbar icon can start the view on the Gmail tab you click it on.
It asks for nothing else, and runs on no other website.
Sharing and sale of data
Unfold Thread has no access to your data outside your own browser, so your data is never shared, sold, or used for advertising or any other purpose.
This website
unfoldthread.run has no analytics, no cookies and no tracking. It loads its typeface from Google Fonts, which means your browser requests the font files from Google's servers when you visit. If you email hello@unfoldthread.run, we use your message and address only to reply to you.
Changes
If this policy changes, the new version will be posted here with a new date. A change that affects how your email is handled will also be noted in the extension's store listing.
