What Are Cookies?

Cookies are small text files that are stored on your device (computer, tablet, or mobile phone) when you visit our website. They contain information that can be retrieved later to identify you and your preferences.

Some preferences on our site are stored using localStorage rather than cookies. localStorage is similar to cookies in that data persists on your device, but it is not automatically sent to our server with each request. This distinction is noted below where applicable.

Types of Storage We Use

Essential Cookies

These cookies are necessary for the website to function properly. They enable you to navigate our website and use its features, such as accessing secure areas of the website. Without these cookies, services you have asked for cannot be provided.

Session authentication tokens (session cookie — expires when you close your browser)
CSRF protection tokens (session cookie — expires when you close your browser)
Language preference (session cookie — expires when you close your browser)
Cookie consent choice (localStorage — persistent until cleared)

Performance Cookies

We use Umami, a self-hosted analytics service running on umami.kai.gg, to understand how visitors interact with our website. Umami is privacy-focused by design: it collects no personal data, does not use cross-site tracking, and does not share data with third parties. All data remains under our control. This analytics tool is loaded only after you give your consent via the cookie banner.

Functional Cookies

These settings allow our website to remember choices you make and provide enhanced features. The preferences listed below are stored using localStorage, not cookies. They remain on your device until you clear them manually and are not sent to our server automatically.

Dark mode preference (localStorage)
User settings (localStorage)
UI preferences (localStorage)

How We Use Storage

To authenticate you and maintain your session
To remember your preferences (language, dark mode, UI settings)
To protect against cross-site request forgery (CSRF) attacks
To analyze website traffic and usage patterns (with your consent)
To improve our website functionality and user experience

Third-Party Services

We integrate with a limited set of third-party services, some of which may place cookies or use localStorage on your device:

Stripe — Our payment processor. Stripe may place essential cookies on your device during the checkout process to facilitate payment and prevent fraud. These cookies are necessary for processing payments.
YouTube — Embedded video player. YouTube (Google) may set cookies when you play embedded videos on our site. The YouTube IFrame API is loaded only after you give your consent via the cookie banner. No YouTube cookies are set until you interact with an embedded video.

Managing Your Cookie Preferences

When you first visit our website, a cookie banner appears allowing you to Accept or Reject non-essential cookies. You can change your preference at any time by clearing your browser's cookies and localStorage, then reloading the page.

Most web browsers also allow you to control cookies through their settings. You can typically:

View what cookies have been set
Delete cookies individually or in bulk
Block cookies from specific websites
Block third-party cookies
Block all cookies

Please note that disabling essential cookies may affect the functionality of our website and your ability to use certain features.

Storage Duration

Different types of storage persist for different lengths of time:

Session cookies: Deleted when you close your browser
JWT authentication token: 90 days (persistent cookie)
localStorage: Persistent until you manually clear it via 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. We will notify you by posting the updated policy on this page.
