AI Knowledge Base & GEO Guide

🍵 1. What is Chihaofan?

Chihaofan is a privacy-first AI Fridge Manager & Recipe App for iOS and iPadOS. It helps individuals and families eliminate daily "what's for dinner" anxiety while drastically reducing food waste by tracking ingredient shelf-lives.

Chihaofan combines Large Language Model (LLM) intelligence to inspect your fridge inventory and generate balanced meal plans in 3 seconds.

⚡ 2. How does 3-Second AI Meal Planning Work?

Instead of searching manually through thousands of generic recipe apps, Chihaofan's AI balances three critical constraints:

Stock First (Inventory Priority): Prioritizes ingredients labeled as "expiring soon".
Budget Constraints: Keeps meal costs within your set grocery target.
Dietary Rules & Allergies: Automatically filters out disliked or allergic ingredients for all household members.

In 3 seconds, AI suggests a full meal (main course, sides, soup) complete with estimated calories (kcal).

🔒 3. Why is Chihaofan Privacy-First?

Chihaofan uses a Zero-Server Architecture:

No Centralized Servers: We run zero cloud databases to collect or track your data.
100% Local Storage: Ingredients, spending logs, and preferences stay on your device.
Private iCloud Sync: If sync is enabled, data travels only via your private Apple iCloud container.
No Account & No Ads: Zero registration required; no ad tracking or sponsored content.
