What Are Cookies

Cookies are small text files that are placed on your device (computer, tablet, or mobile phone) when you visit a website. They are widely used to make websites work more efficiently, to provide a better user experience, and to give website operators information about how their site is being used.

Cookies can be "persistent" (they remain on your device until they expire or you delete them) or "session" cookies (they are erased when you close your browser). They can also be "first-party" cookies (set by the website you are visiting) or "third-party" cookies (set by a different domain).

How We Use Cookies

We use cookies and similar technologies for the following purposes:

  • Authentication: To keep you logged in and maintain your session as you navigate between pages.
  • Security: To protect your account and prevent unauthorized access or fraudulent activity.
  • Preferences: To remember your settings, such as dark mode theme preference and language.
  • Performance: To understand how our Service is being used so we can improve it.

Types of Cookies We Use

The following table provides an overview of the cookies used on our Website:

Cookie Name Type Duration Purpose
bz_session Essential Session Authentication token (JWT). Required to access your account and use the Service.
bz_refresh Essential 30 days Refresh token used to renew your session without requiring re-login.
PHPSESSID Essential Session Server-side session identifier for PHP pages.

Essential Cookies

Essential cookies are strictly necessary for the operation of our Website and Service. Without these cookies, the Service cannot function properly. They include cookies required for:

  • User authentication: The bz_session and bz_refresh cookies are HttpOnly cookies that securely manage your login session.
  • Session management: Server-side session cookies ensure your requests are correctly associated with your account.
  • Security protections: Cookies that help prevent cross-site request forgery (CSRF) and other attacks.

5

Functional Cookies

Functional cookies allow the Website to remember choices you make and provide enhanced, personalised features. These include:

  • Theme preference: We use browser local storage (not cookies) to remember your light/dark mode preference.
  • Dashboard state: Local storage may be used to remember sidebar collapse state and other UI preferences.

These features enhance your experience but are not strictly necessary for the Service to function. If you disable them, the Website will still work but may not remember your preferences.


6

Analytics Cookies

We rely solely on server-side access logs for basic operational monitoring (such as error detection and uptime monitoring). These logs are retained for a maximum of 7 days and are not used for user profiling or behavioural analysis.


7

Third-Party Cookies

Our Service integrates with the following third-party services that may set their own cookies when you interact with them:

  • Stripe: When you make a payment, Stripe's payment processing widget may set cookies necessary for secure payment handling and fraud prevention. These cookies are governed by Stripe's Privacy Policy.
  • Cryptomus: Our cryptocurrency payment provider may set cookies during the payment process. These are governed by Cryptomus's Privacy Policy.

We have no control over cookies set by third-party services. We recommend reviewing the cookie policies of these third parties for more information about their use of cookies.

Local Storage and Similar Technologies

In addition to cookies, we use browser local storage to store non-sensitive preferences such as:

  • Theme setting: Your dark/light mode preference (stored as a key-value pair in localStorage).
  • UI state: Preferences such as sidebar collapse state or notification dismissals.

Local storage data never leaves your browser and is not transmitted to our servers. You can clear local storage through your browser's developer tools or by clearing all site data in your browser settings.

We may update this Cookie Policy from time to time to reflect changes in our practices or for other operational, legal, or regulatory reasons. When we make material changes, we will update the "Last updated" date at the top of this page. We encourage you to review this policy periodically.
