What Are Cookies?
Cookies are small text files that websites store on your device (computer, tablet, or phone) when you visit them. They help websites remember your preferences and keep you signed in. Cookies are a standard part of how the web works and are used by virtually every website.
Cookies We Use
True Blue Horizon uses a minimal set of cookies — only what is necessary to keep you securely logged in and remember your preferences. We do not use advertising, tracking, or analytics cookies.
Essential Cookies (Required)
These cookies are necessary for the application to function. They cannot be disabled.
| Cookie | Purpose | Duration |
|---|---|---|
| sb-*-auth-token | Supabase authentication session. Keeps you securely signed in across page loads. | Session |
| sb-*-auth-token-code-verifier | Used during the OAuth sign-in flow (e.g., Login with Google) to prevent cross-site request forgery. | Session |
These cookies are set as httpOnly where possible, meaning they cannot be accessed by JavaScript and are more secure.
Preference Storage
We use your browser's local storage (not cookies) to remember non-sensitive preferences:
- Theme preference: Whether you've chosen light or dark mode
- Unit system: Whether you prefer metric or imperial units for vessel data
Local storage data never leaves your device and is not sent to our servers.
What We Don't Use
True Blue Horizon does not use:
- Third-party tracking cookies — We do not track you across other websites
- Advertising cookies — We do not serve ads or share data with ad networks
- Analytics cookies — We do not use Google Analytics, Facebook Pixel, or similar tracking tools
- Social media cookies — We do not embed social media widgets that track your activity
Managing Cookies
You can manage or delete cookies through your browser settings. Most browsers allow you to:
- View and delete existing cookies
- Block all cookies or only third-party cookies
- Configure per-site cookie preferences
Please note that blocking essential cookies will prevent you from signing in to True Blue Horizon, as they are required for authentication.
