Prism is a Chrome extension that extracts colors, typography, spacing, and images from the webpage you're currently viewing. This page explains, plainly, what data it does and doesn't touch.
Nothing. Prism does not collect, store, transmit, or sell any user data — personal, behavioral, or otherwise. There are no accounts, no analytics, and no tracking of any kind.
When you click the Prism icon, the extension reads the content of the currently active tab — its colors, fonts, images, and layout — only to display that information back to you inside the popup. This happens locally, in your browser. Nothing is ever sent anywhere.
The Live Edit tab lets you preview color and font changes directly on a page. These changes are temporary: they exist only as long as the tab stays open, and disappear the moment you refresh. Nothing about these edits is saved or transmitted.
The only thing Prism saves is your light/dark theme preference, kept on your own device via Chrome's local storage so it's remembered the next time you open the popup. This value never leaves your browser.
Actions you explicitly trigger — downloading an image, a full-page screenshot, or a design system report — are handled entirely by Chrome's built-in download system. Prism does not upload these files anywhere.
If you choose a Google Font in Live Edit, Prism loads that font's stylesheet directly from Google Fonts — this only happens when you explicitly select a font, and only fetches the font file itself, nothing else.
