Cookie Policy
This policy explains how Shelfie uses cookies and similar technologies when you use our website and app.
Strictly necessary cookies
These are required for the service to function. They cannot be switched off in our systems.
| Name / type | Purpose | Duration |

Supabase Auth cookies (sb-*) | Keep you signed in securely (httpOnly session tokens via SSR) | Session / refresh (as configured by Supabase) |
Functional storage (local)
We use localStorage (not cookies) for non-essential UI preferences:
- Bookcase shelf layout preferences per account.
- Personal shelf positions for binders shared with you.
This data stays on your device and is not sent to our servers except when you save binder content.
Analytics and marketing cookies
Shelfie does not currently use third-party analytics (e.g. Google Analytics) or advertising cookies. If we introduce them, we will update this policy and, where required, ask for consent before setting non-essential cookies.
Stripe
When you manage billing, Stripe Checkout or the Customer Portal may set cookies governed by Stripe's cookie policy.
Managing cookies
You can block cookies in your browser settings, but you will not be able to stay signed in. To clear local preferences, use your browser's site data controls for shelfie.app (or your deployment domain).
