Summary
- No personal data collected. The extension does not gather any information that identifies you.
- No data leaves your device. Nothing is transmitted to any external server.
- No tracking, no analytics, no ads. No third-party scripts are loaded.
- Local-only processing. Everything runs inside your browser.
What the extension does
When you activate the inspector — by clicking the toolbar icon or pressing
Alt+Shift+I — the extension reads the structure (DOM) and computed
styles of the page you are currently viewing so it can:
- Highlight layout types: flex rows, flex columns, grids, blocks, and absolutely-positioned elements
- Visualize spacing, gaps, and element sizes with hatched stripes and pills
- Show the page structure as either a code tree or an abstract tag tree
- Let you copy CSS classes, Tailwind equivalents, or export the structure as JSON
All of this information is shown to you in an inspector panel that lives inside
your own browser. None of it is sent anywhere.
What is stored, and where
Visual Layout Inspector uses chrome.storage.session to remember a small
set of preferences within your current browsing session:
- Whether the inspector is currently active
- Which structure view you prefer (Structure or Tree)
This data is stored locally on your device, is cleared automatically when you
close the browser, and is never transmitted off your device.
Permissions used
activeTab
Grants temporary access to the tab you are currently viewing — and only that
tab — when you explicitly activate the inspector. The permission expires when
you navigate the tab.
scripting
Used to inject the inspector code into the active tab after you click the
toolbar icon or press the keyboard shortcut. Never injected automatically
or in the background.
storage
Used to remember the session preferences described above. Local only;
cleared on browser close.
Children's privacy
Visual Layout Inspector is a developer tool and is not directed at children. It
collects no personal information from any user, regardless of age.
