Analytics & Cookies

CartCycle uses a small number of browser storage entries to keep the app running and, optionally, to understand how it's used during the beta. Here's what's active and what you control.

Essential — account & security

These keep you signed in and the app working. Without them CartCycle can't function, so they're always on.

Always on
Technical details
  • sb-*Auth session tokens. Set when you sign in, cleared when you sign out.
  • themeYour light/dark mode preference. Stored in your browser only — never sent to a server.
  • cartcycle_*Temporary app state flags used during onboarding and the welcome screen. Cleared automatically.

Optional — beta product analytics

During the beta, CartCycle collects usage data to understand which features are working and where things break — so problems can be found and fixed faster. This is entirely optional. Your grocery purchases and receipt contents are never included.

This analytics layer will be removed when CartCycle exits beta.
