Cookie Policy

1. What Are Cookies?

Cookies are small text files that are stored on your browser or device when you visit a website. They are widely used to make websites work efficiently, as well as to provide security and improve user experience.

2. How We Use Cookies

Our platform uses cookies solely for essential technical functionalities. We do not partner with third-party advertising networks, nor do we deploy cross-site tracking, marketing cookies, or behavioral profiling scripts.

3. Strictly Necessary Cookies

These cookies are mandatory for the website to operate correctly and cannot be disabled in our systems. They are typically set in response to actions made by you, such as:

• Authentication & Sessions: Managing your secure login state using NextAuth and session tokens, ensuring you stay connected while completing your English tests.
• User Preferences: Storing your selected English proficiency tier (such as the user-level cookie) to instantly customize your dashboard with appropriate CEFR material (A1 to C2).
• Security: Preventing Cross-Site Request Forgery (CSRF) attacks during signup or login flows.

4. Third-Party Infrastructure

Because our platform runs on decentralized cloud architecture, some essential performance-related identifiers might be processed through our infrastructure hosting partners:

• Vercel: For fast global content delivery, routing, and deployment architecture.
• Supabase: To handle backend requests, API calls, and relational database handshakes securely.

5. How to Control and Delete Cookies

You can control or delete cookies directly through your internet browser configuration settings (such as Chrome, Safari, Firefox, or Edge).

Please note: If you choose to completely block all cookies in your browser settings, you will not be able to log into your account, save your test score histories, or utilize personalized features on this platform.
