Cookie Policy
This Cookie Policy explains how NinjaWatcher uses cookies and similar technologies when you use our website and services.
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 sites work more efficiently, remember your preferences, and understand how visitors use the site. We also refer to similar technologies such as local storage and session storage where relevant.
2. How we use cookies
We use cookies and similar technologies for the following purposes:
2.1 Strictly necessary
These cookies are essential for the website and services to function. They enable core features such as authentication, security, and load balancing. You cannot opt out of these without affecting how the site works.
- Authentication and session — To keep you signed in and maintain your session (e.g., Supabase auth cookies).
- Security — To help prevent fraud and protect your account.
2.2 Functional
These cookies support functionality such as remembering your preferences (e.g., language or region) and improving your experience. They are not strictly required but make the service more useful.
2.3 Analytics and performance
We may use cookies or similar technologies to understand how visitors use our website (e.g., which pages are viewed, how long users stay). This helps us improve the site. Where we use third-party analytics, we aim to use providers that respect privacy and minimize identifiable data.
3. Third-party cookies
Some cookies are set by third-party services we use:
- Supabase — Authentication and database; may set cookies for session and security.
- Stripe — If you use our payment pages, Stripe may set cookies for fraud prevention and checkout. See Stripe's privacy policy for details.
- Hosting / CDN — Our hosting provider (e.g., Vercel) may set cookies for performance and security.
We do not use third-party advertising cookies or sell data derived from cookies for advertising.
4. How long do cookies last?
Session cookies are deleted when you close your browser. Persistent cookies remain on your device for a set period (e.g., days or months) or until you delete them. Our authentication-related cookies typically last for the duration of your session or as configured by our auth provider (e.g., Supabase).
5. Your choices
You can control cookies through your browser settings. Most browsers let you block or delete cookies. Blocking strictly necessary cookies may prevent you from signing in or using certain features. For more information, see your browser's help section (e.g., Chrome, Firefox, Safari, Edge).
If you are in the European Economic Area or UK, we will obtain your consent for non-essential cookies where required by law before placing them.
6. Updates
We may update this Cookie Policy from time to time to reflect changes in our practices or in law. We will post the updated policy on this page and update the “Last updated” date.
