Burnline (“we”) provides LLM API spend analytics. This policy explains what data we collect and how it is used.
When you sign in we store your authentication identifiers (email, OAuth subject IDs) via Supabase Auth so we can maintain your session and subscription entitlement.
API keys you paste into Burnline are stored only on your device (Secure Store / keychain). They are sent directly to the provider (e.g. OpenRouter) to fetch your usage data and are not uploaded to Burnline servers.
Burnline caches public OpenRouter ecosystem rankings on our servers so signed-in users can browse platform-wide stats without connecting a personal key.
Subscriptions are processed by Apple or Google. We use RevenueCat to verify entitlements. We do not receive or store your full payment card details.
We do not sell personal information. We do not use third-party advertising or cross-app tracking SDKs.
You can delete your Burnline account in Settings → Delete account. This removes your auth user from our systems. Manage or cancel App Store subscriptions separately in your Apple ID settings.
