Cookie Policy
Last updated: April 28, 2026
The short version
ColorUI sets no tracking cookies, runs no analytics, and serves no ads. There is no consent banner because there is nothing to consent to — we have nothing to track.
What we do store on your device
A handful of preferences live in your browser's localStorage so the site feels personal across visits. None of these are HTTP cookies, none are sent to our servers, and none leave your device.
| Key | Purpose | Duration |
|---|---|---|
colorui-theme | Remembers your light/dark theme choice. | Until you clear site data. |
colorui-recent | Your recently used colors so they reappear in the picker. | Until you clear site data. |
colorui-palette | Your working palette, so it persists across pages. | Until you clear site data. |
What we do not do
- No Google Analytics, Plausible, Fathom, or any other analytics SDK.
- No advertising network. No AdSense, no retargeting pixels.
- No third-party trackers, no fingerprinting, no session replay.
- No cross-site cookies. No accounts, no logins, no email walls.
Clearing your local data
Every browser exposes a "Clear site data" option in its developer tools or privacy settings. Clearing it for colorui.io resets the theme, recent colors, and working palette — that is the entirety of what ColorUI stores about you.
