Cookie Policy

Last updated: October 15, 2025

This Cookie Policy explains how EduArc AI uses cookies and similar technologies to recognize you when you visit our platform. It explains what these technologies are and why we use them, as well as your rights to control our use of them.

1. What Are Cookies?

Cookies are small text files that are stored on your computer or mobile device when you visit a website. They are widely used to make websites work more efficiently and provide information to website owners.

Cookies set by the website owner (in this case, EduArc AI) are called "first-party cookies." Cookies set by parties other than the website owner are called "third-party cookies." Third-party cookies enable third-party features or functionality to be provided on or through the website (e.g., analytics, authentication services).

2. Why We Use Cookies

We use first-party and third-party cookies for several reasons. Some cookies are required for technical reasons in order for our platform to operate—we refer to these as "essential" or "strictly necessary" cookies. Other cookies enable us to track and target user interests to enhance the experience on our platform. Third parties serve cookies through our platform for authentication, analytics, and other purposes.

3. Types of Cookies We Use

3.1 Essential Cookies

These cookies are strictly necessary to provide you with services available through our platform and to use some of its features, such as access to secure areas.

3.2 Performance and Analytics Cookies

3.3 Functionality Cookies

3.4 Authentication Cookies (Third-Party)

We use Supabase for authentication services. Supabase sets cookies to manage user authentication and session state. These cookies are essential for the functioning of our authentication system.

4. How Long Do Cookies Stay on My Device?

The length of time a cookie remains on your device depends on whether it is a "persistent" or "session" cookie:

  • Session Cookies: These cookies last only as long as your online session. They are deleted from your device when you close your browser.
  • Persistent Cookies: These cookies remain on your device after you close your browser and last for the time specified in the cookie. We use persistent cookies when we need to remember you for more than one browsing session.

5. First-Party vs. Third-Party Cookies

First-party cookies are cookies that we place on your device directly. We use these cookies to remember your preferences and improve your experience.

Third-party cookies are placed on your device by our trusted partners:

  • Supabase: For authentication and user management
  • Google Analytics: For understanding usage patterns (if enabled)
  • Vercel: For hosting and content delivery

6. How to Control Cookies

You have the right to decide whether to accept or reject cookies. You can exercise your cookie preferences by:

6.1 Browser Controls

Most web browsers allow you to control cookies through their settings preferences. However, if you limit the ability of websites to set cookies, you may impact your overall user experience, since it will no longer be personalized to you. It may also prevent you from using certain features of our platform.

Here are links to cookie management for popular browsers:

6.2 Opt-Out of Analytics

If we use Google Analytics, you can opt out by installing the Google Analytics Opt-out Browser Add-on.

6.3 Essential Cookies

Please note that if you block essential cookies, you will not be able to use key features of our platform, including logging in and accessing your account.

7. Do Not Track Signals

Some browsers have incorporated "Do Not Track" (DNT) features that can send a signal to the websites you visit indicating you do not wish to be tracked. Because there is not yet a common understanding of how to interpret the DNT signal, our platform does not currently respond to browser DNT signals. Instead, you can use the range of other tools to control data collection and use, as described above.

8. Other Tracking Technologies

In addition to cookies, we may use other tracking technologies:

  • Local Storage: We use browser local storage to store user preferences, theme settings, and temporary data for improved performance.
  • Session Storage: Used to maintain state during a single browsing session, such as keeping track of your current project.
  • Web Beacons: Small graphic images (also known as "pixel tags" or "clear GIFs") that may be included on our platform for analytics purposes.

9. Updates to This Cookie Policy

We may update this Cookie Policy from time to time to reflect changes in the cookies we use or for other operational, legal, or regulatory reasons. We encourage you to review this Cookie Policy periodically to stay informed about our use of cookies.

The date at the top of this Cookie Policy indicates when it was last updated. Any changes will take effect immediately upon posting the updated Cookie Policy.
