Consequences of Disabling Cookies
You are free to block or delete cookies. However, if you disable strictly necessary cookies:
- Authentication may not work — you may be unable to log in or stay logged in
- Payment processing may fail — Stripe requires cookies for secure transactions
- Your preferences (language, theme) may not be saved between visits
- Some features may not function correctly or may be unavailable
Disabling optional cookies (analytics, marketing) will not affect the core functionality of the service.
