Cookie Policy
Last updated: 3 January 2026
This Cookie Policy explains how Chameleon Check ("Chameleon", "we", "us", or "our") uses cookies and similar technologies when you use our service at chameleoncheck.app.
We use minimal cookies—only what's essential for the service to function. We do not use advertising or tracking cookies.
What Are Cookies?
Cookies are small text files that websites store on your device. They help websites remember information about your visit, like your login status and preferences.
Cookies We Use
We only use essential cookies required for the service to function:
| Cookie Name | Provider | Purpose | Duration |
|---|---|---|---|
| __clerk_* | Clerk | Authentication session management | Session / 7 days |
| __client_uat | Clerk | User authentication token | 1 year |
These cookies are classified as strictly necessary under UK GDPR and PECR. They are essential for you to sign in and use authenticated features of Chameleon. Without them, the service cannot function properly.
What We Don't Use
We do not use:
- Advertising or marketing cookies
- Third-party tracking cookies
- Social media cookies
- Analytics cookies (our analytics service is cookieless)
Analytics
We use Umami for website analytics. Umami is a privacy-focused analytics service that operates without cookies. It does not track you across websites, does not collect personally identifiable information, and is fully GDPR compliant.
Local Storage
In addition to cookies, we use your browser's local storage for temporary functionality:
- Session Storage — Temporarily stores document check results during the sign-in flow, so you don't lose your progress. Cleared when you close the browser tab.
- IndexedDB — Temporarily caches your uploaded file during processing. Automatically cleared after use.
This data stays on your device and is not transmitted to our servers.
Managing Cookies
Since we only use essential cookies for authentication, blocking them will prevent you from signing in to Chameleon. If you wish to clear cookies:
- Chrome: Settings → Privacy and Security → Clear browsing data
- Firefox: Settings → Privacy & Security → Cookies and Site Data → Clear Data
- Safari: Preferences → Privacy → Manage Website Data
- Edge: Settings → Privacy, search, and services → Clear browsing data
Changes to This Policy
If we change our use of cookies, we will update this page. Material changes will be communicated via our website or email.
