Privacy Policy

The short version

The ImageGuide — Image Auditor browser extension collects no personal data. It has no server, no account, and no analytics. It sends nothing anywhere. Every measurement it makes stays on your device and disappears when you close the popup.

We do not sell, share, or transfer any user data, because we never receive any.

What the extension handles

The extension reads the images of the page you are looking at, and only after you click its toolbar icon. Here is everything it touches, and where each item goes.

The extension runs no background process. When the popup is closed, it does nothing at all.

Permissions, and why

activeTab

Reads the images of the current tab, and only after you click the icon. It gives access to that one tab, for that one visit.

scripting

Injects two functions into the page. The first gathers a record of every image. The second scrolls to one image and outlines it when you click its name. No code is fetched from a remote source.

storage

Stores your filter and sort choice on your own machine. Nothing else.

Host access (optional)

Never requested at install time. A cross-origin image hides its transfer size unless the server sends a Timing-Allow-Origin header. When you press Measure the real sizes, the extension asks for access only to the origins that serve those images, then reads the Content-Length header of each one. You can decline, and the extension continues with estimates.

Network requests

The extension makes a network request in one case only: when you press Measure the real sizes. It then asks each image server for the size of the file, using a HEAD request, with credentials omitted. It sends no cookies and no identifiers. It reads the response headers and discards the rest.

The thumbnails in the popup load from the same addresses the page already used, so they usually come from your browser cache.

This website

The extension and this website are separate. imageguide.dev uses privacy-focused analytics that count page views without cookies and without tracking anyone across sites. The extension sends nothing to this website, or anywhere else.

Children

The extension collects no data from anyone, of any age.
