Privacy Policy

Last updated: October 6, 2026 · Applies to the Kernhue browser extension and its website and API at kernhue.roledawn.com.

Kernhue shows the fonts, colors and CSS of web pages you choose to inspect. We built it to collect as little as possible: no ads, no analytics, no tracking, and nothing injected into the sites you visit.

What Kernhue reads

• Only the page you choose. Kernhue runs on a tab only after you click its toolbar button or press its keyboard shortcut (Chrome's activeTab permission). It has no access to other tabs and does not run in the background.
• Everything is processed in your browser. Fonts, colors, CSS, the page palette and exported design tokens are computed locally. Page content is not uploaded.

What leaves your browser

Data	Sent to	Why	Kept
Only when you click “Name with AI”: token values (color codes with usage counts, font names, font sizes and weights) and the site's hostname	Our API (Cloudflare), then our AI provider (Anthropic)	To suggest semantic token names and design notes	Not stored by us. Processed and discarded. Not used to train AI models. No page text, no full URLs.
A random device ID	Our API	To count free AI namings and link a Pro license to your browser	While you use Kernhue
Usage counts and a one-way hash of your IP address	Our API (Cloudflare)	To enforce free allowances and prevent abuse	Grouped by day; we never store your raw IP address
Purchase details (email, payment)	Dodo Payments, our merchant of record	To process payments and issue your license key	As required by law; we keep your license key, plan, email and status

Stored in your browser

Your preferences (color format, auto-copy, panel side), your last 12 picked colors, the random device ID and your plan status are kept in the extension's local storage. Uninstalling Kernhue removes them.

What we never do

• We do not collect browsing history, page content, keystrokes or form data.
• We do not sell or rent data, or use it for advertising or credit decisions.
• We do not add ads, pop-ups, affiliate links or any other content to the pages you visit.
