DesignKit inspects the page you point it at. The results are shown in your own browser. There is no DesignKit server, no account, no analytics and no tracking. We cannot see anything you inspect, because it is never sent to us.
Who this is from
DesignKit is developed by Rahul Sehjal.

What DesignKit does
DesignKit is a page inspection tool. When you click its toolbar button on a page, it opens a docked panel with 23 tools across seven categories: measurement, colour, type, code, assets, accessibility and capture.
Those tools read element sizes and positions, computed CSS, text content, colours, fonts, image dimensions, and accessibility attributes such as alt text and heading levels.
All of this happens inside your browser. Results appear in DesignKit's own panel on the same page you opened it on. On every other tab, and on that tab until you click, the extension does nothing.
What data is involved
DesignKit handles two categories of data.
The page you inspect
DesignKit reads the content of the page you point it at so its tools can measure, sample colour and audit accessibility. This is read in memory while you look and is never written down.
Findings you choose to save
When you press Save on a measurement or audit result, DesignKit keeps the reading, a short description of the element it came from, and the address of the page you took it on, so that an exported report can say where each result came from.
Both stay on your device. Neither is transmitted to us or to anyone else.
Where it is stored
DesignKit uses chrome.storage.local, Chrome's local storage area on your own machine. It stores three things:
- Your settings - theme, which side the panel docks to, grid defaults, whether keyboard shortcuts are on, and which one-time tips you have dismissed
- Colour history - the last twelve colours you sampled with the eyedropper, so you can reuse them
- Saved findings - measurements and audit results you explicitly pressed Save on, up to a maximum of 200
None of it is synced to a Google account. None of it leaves your device.
DesignKit never writes to the page's own localStorage or sessionStorage, so it does not leave anything behind on the sites you inspect.
Network activity
DesignKit makes one kind of network request in its entire codebase.
When you open the Image Inspector and ask an image for its file size, DesignKit sends a same-origin HTTP HEAD request to that image's own address and reads two response headers: content-length and content-type.
It sends no data with the request and receives no response body.
That is the complete list. There are no analytics calls, no error reporting, no update pings, no remote configuration, and no remotely loaded code. Every script, style and icon the extension uses ships inside the extension package.
Permissions, and why each one exists
| Permission | What it is for |
|---|---|
| activeTab | So the tools can read the one tab you opened DesignKit on. |
| scripting | So the tool modules load into that tab on demand, rather than running on every page you visit. |
| storage | So your settings and saved findings survive between sessions. |
| downloads | So screenshots, extracted SVGs, favicons and exported reports save when you ask for them. |
| Access to all sites | A page inspection tool has to work on whatever page you are looking at, whether that is a staging server, a client's live site, localhost or an internal tool behind a login. No fixed list of sites would do the job. DesignKit stays inert on every page until you click its toolbar button. |
What DesignKit never does
Third parties
There are none. DesignKit contains no third-party libraries, no software development kits, no analytics providers and no advertising networks. Nothing in the extension communicates with any service, including ours.
Your control over your data
Everything DesignKit stores is on your machine and under your control.
- Clear your saved findings from the Findings tray
- Clear your colour history from Settings
- Reset every preference from Settings
- Remove the extension to delete all of it at once - nothing survives uninstallation
Because none of your data ever reaches us, there is nothing for us to delete on your behalf and no request you need to make.
Children
DesignKit is a professional tool for designers and developers. It is not directed at children, and it collects no data from anyone, children included.
Changes to this policy
If DesignKit's data handling ever changes, this page will be updated before the change ships, and the date at the top will change with it.
