1. What Are Cookies

Cookies are small text files that are stored on your device when you visit a website. They are widely used to make websites work more efficiently, provide a better user experience, and give site owners useful information about how their sites are used.

2. How We Use Cookies

Chartix uses cookies and similar technologies (such as localStorage) for the following purposes:

  • Authentication: We use cookies to keep you signed in and remember your session across page loads.
  • Preferences: We store your theme preferences (dark/light mode, accent color) and layout settings locally so the app loads with your preferred configuration.
  • Security: Cookies help us detect and prevent fraudulent activity and protect your account.
  • Performance: We may use analytics cookies to understand how users interact with the Service so we can improve performance and user experience.

3. Types of Cookies We Use

3.1 Essential Cookies

These cookies are strictly necessary for the Service to function. They enable core functionality such as authentication, security, and session management. You cannot opt out of essential cookies as the Service will not work without them.

3.2 Functional Cookies

These cookies remember your preferences and settings (such as theme, language, and layout choices) to provide a personalized experience.

3.3 Analytics Cookies

These cookies help us understand how visitors interact with our Service by collecting and reporting information anonymously. This data helps us improve the Service and fix issues.

4. Local Storage

In addition to cookies, Chartix uses browser localStorage to persist your application state, including your theme settings, notification preferences, and cached data. This data is stored entirely on your device and is not transmitted to our servers unless required for syncing purposes.

5. Third-Party Cookies

Some third-party services integrated into Chartix may set their own cookies:

  • Firebase (Google): Used for authentication and database services.
  • Stripe: Used for payment processing. Stripe may set cookies to prevent fraud and process payments securely.

We do not control the cookies set by these third-party services. Please refer to their respective privacy policies for more information.
