What we collect / 我们收集什么

Food diary, custom foods, weight, and settings stay on your phone by default. Android uses Google sign-in and iOS uses Sign in with Apple, only to identify you. The device may store your name, email, and photo (Apple may not provide email or name). After you sign in, tapping sync writes a backup to our server.

饮食记录、自定义食物、体重和设置默认只在本机。Android 用 Google 登录，iOS 用 Apple 登录，只用来识别你是谁。本机可能保存姓名、邮箱和头像（Apple 不一定提供）。登录后点同步会把备份写到我们的服务器。

Calorie estimates / 热量估算

Automatic calorie estimates are a Premium feature. After purchase, custom-food estimates send the food description to Volcano Engine Ark in Beijing. Unpaid users enter calories by hand. Do not put information that identifies you in the food name. The API key stays on our server.

自动估算热量是 Premium 功能。付费后，自定义食物估算会把食物描述发到北京的火山引擎方舟。未购买时请手填热量。请不要在名称里写可识别你的信息。API 密钥只保存在我们服务器上。

Purchases / 购买

Premium is a one-time unlock for AI estimates, account sync, and older weekly history. It is sold on Google Play or the App Store. We store a hashed purchase token so we can restore on a new phone without sharing the token.

Premium 一次买断，包含 AI 估算、账号同步和往期周历史，通过 Google Play 或 App Store 购买。我们保存购买凭证的哈希，方便换机恢复，不会保存可用的原始凭证。

Permissions / 权限

The app uses the network for estimates, account sync, and store or support links. Daily reminders use notification permission. Android signs in through the system Google account picker without reading the account list. The app does not automatically access your photo library, location, or contacts. Only images you deliberately select under Send Feedback are submitted with that feedback.

应用使用网络做估算、账号同步和打开商店或支持链接。每天提醒使用通知权限。Android 通过系统账号选择器登录 Google，无需读取账号列表。应用不会自动读取相册，也不使用定位或通讯录；只有当你在「发送反馈」中主动选择图片时，所选图片才会随反馈提交。
