Privacy policy.

Last updated 9 May 2026.

ThreadView is a Chrome extension that runs entirely in your browser. There is no backend server, no account, no telemetry, and no data shared with anyone.

What we collect

Nothing. ThreadView has no analytics, no telemetry, no error logging, no usage tracking, and no remote services it talks to. There is no backend.

What ThreadView reads from your browser

When you click the ThreadView button on a Gmail tab, the extension reads:

The Gmail URL pathname, to determine which Google account index you are using.
A few DOM attributes from the open Gmail thread, to identify the thread you have open.
A list of recent network request URLs from the page's resource timing API, to find Gmail's per-session inbox key.

It then asks Gmail's own server for the print-view HTML of the open thread, using your existing browser session cookies. The print-view HTML is the same one Gmail's own Print button uses; ThreadView is reading what Gmail already serves.

Where data goes

Nowhere. The fetched HTML is parsed and rendered in a new tab on your machine. It is not transmitted to ThreadView or any third party. The extension makes no outbound network requests other than the authenticated fetch to mail.google.com that retrieves the thread you asked to read, and (when applicable) similar authenticated fetches to mail.google.com for inline image attachments in that thread.

Plainly: if you turn off your network connection after Gmail loads, you can still open ThreadView on a thread you've already viewed (the rendered HTML stays in your tab). The extension itself does not phone home.

Permissions

ThreadView requests the minimum permissions to function:

Host permission for mail.google.com. Required to fetch Gmail's print-view HTML using your existing browser session. Without this permission, no thread can be read. ThreadView does not request access to any other domain.
Storage. Used only to remember your reading-width preference (Medium, Wide, X Wide) across viewer tabs and a one-time installation timestamp. Stored locally in your browser; never transmitted.

Third parties

None. ThreadView does not integrate any analytics SDK, advertising network, crash-reporting service, or third-party API. The extension's bundled code does not load any external JavaScript at runtime.

Cookies

ThreadView does not set any cookies. The cookies your browser sends to Gmail when fetching thread HTML are your existing Gmail session cookies — the same ones you would send by visiting Gmail in a tab.

Children

ThreadView is a productivity utility for adult Gmail users. It is not directed to children under 13.

Changes

If this policy changes, the new version will be posted at this page and the "last updated" date above will reflect the change. Material changes — especially anything that would result in data being transmitted — will also be noted in the Chrome Web Store listing description.
