Last updated: April 2026. This policy explains how we use cookies and similar technologies on our website.
Cookies are small text files stored on your device (computer, tablet, or phone) when you visit a website. They are widely used to make websites work efficiently, provide a better user experience, and supply information to website owners.
Cookies can be "first-party" (set by our website) or "third-party" (set by external services we use). They can be "session cookies" (deleted when you close your browser) or "persistent cookies" (remain until they expire or you delete them).
We use cookies for the following purposes:
• Essential Cookies: Required for core website functionality — authentication, security (CSRF protection), and session management. Without these, the website cannot function properly.
• Functional Cookies: Remember your preferences such as theme settings and language choices to provide a personalized experience.
• Analytics Cookies: Help us understand how visitors use our website — which pages are visited most, how users navigate, and where they encounter issues. This data is aggregated and anonymous.
The following table lists the specific cookies used on our website:
| Cookie | Purpose | Type | Duration |
|---|---|---|---|
| next-auth.session-token | Stores your authentication session so you stay logged in across pages. | Essential | 30 days |
| next-auth.csrf-token | Protects against cross-site request forgery (CSRF) attacks during login. | Essential | Session |
| next-auth.callback-url | Remembers the page to redirect you to after login. | Essential | Session |
| __Host-next-auth.csrf-token | Secure CSRF token for HTTPS connections. | Essential | Session |
| theme-preference | Stores your preferred color theme (light/dark). | Functional | 1 year |
| _ga / _gid | Google Analytics cookies for understanding website traffic and user behavior. | Analytics | 2 years / 24 hours |
You can control and manage cookies in several ways:
Browser Settings: Most browsers allow you to refuse or delete cookies through their settings. The exact steps depend on your browser:
• 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
Important: Blocking essential cookies will prevent you from logging in and using core features of our website. If you choose to block cookies, some parts of the website may not function correctly.
Do Not Track: We respect the Do Not Track (DNT) signal. When enabled in your browser, we limit non-essential cookie usage.
Some cookies are placed by third-party services that appear on our pages:
• Google Analytics: Used for website traffic analysis. Google's privacy policy applies to these cookies.
• Google OAuth: Used during Google sign-in authentication flow.
• Razorpay: May set cookies during the payment process for paid events.
We do not control third-party cookies. Please refer to the respective third-party privacy policies for more information.
In addition to cookies, we may use similar technologies:
• Local Storage: Used to store theme preferences and non-sensitive UI state. Local storage data persists until explicitly cleared.
• Session Storage: Used for temporary data during your browsing session. Cleared when you close the browser tab.
These technologies are subject to the same principles and controls described in this policy.
We may update this cookie policy from time to time to reflect changes in the cookies we use or for operational, legal, or regulatory reasons. We encourage you to revisit this page periodically to stay informed.
