Label images and extracted food data
When you start an AI analysis, the app sends the selected label image to the Litmu API for extraction. The result can include product name, brand, serving size, nutrition values, ingredients, additive details, ingredient insights, and AI summaries.
Local scan history
Scan history, favorites, daily status labels, and saved result payloads are stored locally on your device. Litmu does not currently provide cloud sync for scan history.
Personal settings
If you add allergens, diet avoidances, health focus, or a personal note, the app uses those settings to highlight relevant alerts and result details.
Authentication and entitlement data
Litmu uses Firebase anonymous authentication and App Check to issue short-lived API sessions. Subscription entitlement status is handled through RevenueCat and the App Store.
Analytics and usage data
Litmu sends product interaction and usage analytics to PostHog, including events such as scans, result views, paywall views, and subscription actions. API usage logs support quota enforcement and service reliability.
