1. What Are Cookies?
Cookies are small text files that are placed on your computer or mobile device when you visit a website or use a web application. They are widely used to make websites work more efficiently, provide a better user experience, and give website owners useful information about how their sites are being used.
In addition to cookies, we may also use similar technologies such as local storage, session storage, and authentication tokens (JWT) to maintain your login session. These are essential for the platform to function correctly.
This policy covers both the AsterStream marketing website (asterstreambuild.com) and the web application platform used after login. The types and purposes of cookies differ between these two contexts.

We use cookies for the following core purposes:
- Authentication: To keep you logged in securely as you navigate the platform

- Preferences: To remember your settings such as language, dashboard layout, and notification preferences
- Analytics: To understand how the platform is used so we can improve it (with your consent)
