Privacy policy
The short version: everything Scaffold reads from a page stays in your browser. There are no analytics, and nothing it captures is sent, sold or shared. If you buy Pro, a small license service checks your plan using your email and a random ID for each browser, and nothing else.
Who this covers
This policy covers the Scaffold browser extension for Google Chrome and Microsoft Edge, and this website. Scaffold is made by (“we”).
What the extension reads, and when
Scaffold does nothing until you start it on a tab, by clicking its icon, using a keyboard shortcut or choosing it from its menu. Then, on that tab only, it reads:
- The page's structure and styles: elements, their computed styles, text, image and icon references, and layout, to build the Blueprint, prompts, reference packs and design skills.
- Screenshots of the visible tab, when you download a reference pack. They're taken in your browser and placed in the zip you save.
- A reference pack you choose, when you use Compare. The zip is opened in your browser and compared there.
Scaffold doesn't read other tabs, your browsing history, passwords, form entries, cookies or anything on a page you haven't started it on.
Where it goes
Nowhere outside your computer. Everything Scaffold reads stays in that tab's memory until you close Scaffold. Files leave the tab only when you download them, and they go to your computer. Scaffold never sends page content, screenshots or packs anywhere.
What it stores
Two preferences: light or dark theme, and the last “Build for” target. They're kept in your browser's local storage for the site you used Scaffold on, and never leave your browser. You can clear them by clearing that site's data.
In its own storage, Scaffold keeps a random ID for this browser. If you turn on Pro, it also keeps your signed license and the email you signed in with. Uninstalling Scaffold deletes them.
Permissions, and why
activeTab | Lets Scaffold read the current tab only after you start it there. |
|---|---|
scripting | Runs Scaffold in the tab you started it on. |
offscreen | Plays the build's sound effects, which are synthesized in your browser, when a site blocks audio. |
storage | Keeps this browser's random ID and, with Pro, your license. |
contextMenus | Adds “Compare with a reference pack” to the icon's right-click menu. |
| Optional site access | Some apps, like Power Apps, show a page inside a frame on another domain. Scaffold asks you, once and only for that domain, before reading it. You can remove it any time in the browser's extension settings. |
Paying for Pro
Purchases are handled by , which sells Scaffold Pro as the merchant of record and collects your name, email and payment details under its own privacy policy. We receive your email address and order details so we can provide your license and support. We never see your full card details.
Your Pro license
To turn on Pro, you enter the email you paid with and a 6-digit code we email you. After that, Scaffold checks your license about once a day. Our license service, which runs on Cloudflare, stores:
- your email and your customer ID from the payment provider;
- your plan and its status, such as active, canceled or refunded, and when it renews or ends;
- up to 3 browser IDs, each with a name like “Edge on Windows” and when it last checked in;
- the times Pro was turned on in a new browser in the last two days, to stop a license being shared.
Sign-in codes are stored only as a one-way hash and expire after 10 minutes. They're delivered by our email provider, Resend. The daily check sends only your license and the browser's random ID, never anything about the pages you use Scaffold on.
To have your license records deleted, email us. Payment records stay with for as long as tax law requires.
This website
This website sets no cookies of its own and runs no analytics. It loads fonts from Google Fonts, so Google receives your IP address when the page loads. The pricing section loads 's checkout script, which may set its own cookies when you open checkout. It remembers your light or dark theme choice in your browser's local storage.
Limited use
We don't sell or transfer user data to third parties, don't use it for anything unrelated to Scaffold's single purpose, and don't use it to determine creditworthiness or for lending. Scaffold has no user data to sell in the first place.
Children
Scaffold is a professional design tool and isn't directed at children under 13.
Changes
If this policy changes, we'll update the date above. If Scaffold ever starts collecting data, this page will say so before that version ships.
