Privacy

Last updated 25 August 2026

Mobile View collects nothing. There is no account, no analytics, no telemetry and no server of ours involved at any point. Every page you preview is rendered by your own browser, and nothing about it is sent anywhere.

What the extension stores

Two things, both in your browser's own extension storage, and neither of them leaves the machine:

Your settings. The devices you picked, any custom sizes you created, your favourites, the theme, and whether the preview should start automatically.
Which tabs are active. A short-lived note of the tabs currently showing a preview, kept in session storage so the view can be restored if the tab reloads. It is discarded when the browser closes.

You can erase all of it at any time by removing the extension.

What it never touches

The extension does not read, log, transmit or store the content of the pages you preview. It does not see your passwords, form entries, cookies or browsing history as data it can keep. The site simply loads in a frame on your own tab, exactly as it would in any other tab.

Why it asks for the permissions it asks for

Access to sites you use it on. The preview is the real site, loaded inside the tab you are already on. Without access to that page the extension cannot draw anything.
Modifying request headers on that tab. Two headers, and only for the frames the extension creates. It sends a mobile user agent, because the server decides which layout to return before any of our code runs, and it removes the X-Frame-Options and frame-related Content-Security-Policy rules that would otherwise stop a site from being framed by itself. Nothing else in the request or the response is altered.
Storage. For the settings above.
Side panel and scripting. To show the panel and to draw the frames on the tab.

Third parties

There are none. No SDKs, no trackers, no fonts or scripts fetched from anyone else while the extension runs, and no data shared with, sold to or bought from anybody.

Changes

If this policy ever changes, the date at the top changes with it, and the previous wording stays in the project's public history.
