Cookie Policy
1What Are Cookies
Cookies are small text files placed on your device when you visit a website. They are widely used to make websites work efficiently, to remember your preferences, and to provide information to website owners.
CLASSARK uses cookies and similar browser storage technologies (such as localStorage and sessionStorage) to operate the platform and provide a seamless user experience.
2Cookies We Use
CLASSARK uses only the cookies necessary to operate the platform. We do not use advertising, tracking, or analytics cookies.
| Cookie / Storage Key | Type | Purpose | Duration |
|---|---|---|---|
| Firebase Auth Token | Essential | Maintains your authenticated session so you stay logged in across page navigations and browser sessions | Until sign-out or token expiry |
| Firebase ID Token (IndexedDB) | Essential | Stored by Firebase SDK to manage authentication state and enable secure API calls | Session / token lifetime |
| Video Player State (localStorage) | Functional | Remembers video playback preferences (volume, quality) for lesson video content | Persistent (local device only) |
3Essential Cookies
Essential cookies are strictly necessary for the platform to function. Without them, core features like login and session management would not work. These cookies cannot be disabled while using CLASSARK.
Firebase Authentication, which powers our login system, uses browser storage to maintain your authenticated session. This is a security requirement and does not involve tracking your browsing behaviour.
4Third-Party Cookies
Some third-party services embedded in CLASSARK may set their own cookies or use similar storage mechanisms. These include:
- Google Firebase — sets cookies related to authentication and security. Governed by Google's Privacy Policy.
- Zoom — live class sessions run through the Zoom Meeting SDK directly in your browser (no app download required), which may set cookies to support the meeting connection. Governed by Zoom's Privacy Policy.
5Managing Cookies
You can control cookies through your browser settings. Most browsers allow you to block or delete cookies. However, disabling essential cookies will prevent you from logging in and using the platform.

- Chrome — Settings → Privacy and Security → Cookies and other site data
- Firefox — Settings → Privacy & Security → Cookies and Site Data
- Safari — Preferences → Privacy → Manage Website Data
- Edge — Settings → Cookies and Site Permissions → Manage and Delete Cookies
