ChiHaoFan · Privacy Policy

1. A Local-Only App, No Servers of Our Own

• ChiHaoFan is a local-only client app. We do not operate any backend server, and we do not collect, upload, or store any of your data — including your groceries, meal plans, check-ins, expense records, family profiles, AI conversation / meal-request content, or any third-party API keys you enter.
• All data is stored only on your device. To delete everything: Settings → Danger Zone → Delete All Data. Your AI API key can be removed or replaced at any time in Settings → AI Meal Service.

2. Third-Party AI Services (Optional; Only When You Actively Use Them)

• If you configure an API key for a third-party AI provider of your choice (such as DeepSeek, Doubao, or OpenAI), meal-planning / photo-recognition / health-report requests send the relevant text or images directly from your device to that provider's servers. Data transmission and processing are handled by that provider under its own privacy policy.
• Your API key is stored only on your device and is never uploaded to any server. Without an AI key, the app works fully offline.
• iCloud backup (iOS only, optional): backup files are stored in your own Apple account.

3. System Permissions & Sensors (Invoked Only as Needed After Privacy Consent)

• The app does not access your contacts, location, or SMS, or any other permission unrelated to its features. Network requests happen only when you actively initiate one.
• Accelerometer Sensor (Gravity Sensor / Device Info - Accelerometer Data):
  • Data Accessed: Device accelerometer sensor readings (and hinge angle sensor on foldable devices).
  • Purpose & Method: Used solely on the "My Fridge" screen and produce crisper cards to render 3D tilt parallax effects and gentle shake interactions. Sensor readings are computed in real time in local memory only — never stored, logged, or uploaded to any server, and never used for ads or shake-to-redirect.
• Notifications: mealtime companion reminders (at most two per day, can be turned off).
• Microphone & speech recognition: real-time speech-to-text when you chat with Qingtuantuan by voice; recordings are not stored.
• Camera / Photos: requested only when you actively use "Scan Receipt". Images are sent only to the AI provider you configured; the app does not retain them.
• Clipboard: written only when you actively tap a "Copy" button.

4. Third-Party SDK Directory

• Huawei HMS Core / In-App Purchases (IAP) SDK & AppService Update SDK (Huawei AppGallery release only)
  • Provider: Huawei Software Technologies Co., Ltd.
  • Personal Data Collected: Device information (device model, OS version), network information, basic app information, and in-app order information
  • Purpose & Method: Provide in-app purchase checkout, purchase restoration, and AppGallery version update checks
  • Privacy Policy: https://consumer.huawei.com/cn/privacy/privacy-policy/

5. Children

This app does not provide services specifically for children under 14. Use under the guidance of a guardian is recommended.
