一、我们收集什么
本应用的核心功能无需注册即可使用；若你选择创建账号，我们仅按下述「七、账号」所述范围收集信息。饮食记录、训练时间与相位计划等数据仅存储在本设备，不上传到我们的服务器。
二、拍照识别与照片处理
1. 「拍照识别」功能会将照片内容传输至大模型服务商（智谱 AI，其生成式人工智能服务已完成备案），仅用于识别食物与配料，不作其他用途。
2. 照片不进入我们的服务器、不保存到你的相册、不用于任何广告；仅在识别过程中临时使用，识别完成（无论成功或失败）即删除。
3. 是否使用拍照识别由你决定：改用「手动输入」则不会传输任何照片。
4. 建议与判断不由 AI 生成——全部由基于公开文献的确定性规则引擎在本机计算。
三、配料文本的 AI 处理
识别出的配料文本会发送至大模型服务商用于结构化提取（仅配料文本，不含任何身份信息）；成分判断与时机建议全部由本机规则引擎计算。
四、匿名使用统计
开启「匿名使用统计」时（默认开启，可在设置中随时关闭），我们收集与身份无关的使用事件（如功能点击）用于改进产品；关闭后不上报任何事件。
五、额度
免费扫描额度在本机记账，不关联你的身份。
六、未成年人
本应用不向未成年人提供热量限制类建议。
七、账号（可选）
1. 是否创建账号由你决定。不创建账号也可使用扫描、决策与本地记录；账号用于跨设备恢复订阅与保留云端权益。
2. 我们收集什么。创建账号时：① 你的邮箱地址（用于登录验证与账号安全通知）；② 若使用 Apple 登录，Apple 返回的账号标识符（随机唯一 ID）与你选择共享的邮箱（含 Apple「隐藏邮箱」中转地址，我们同样仅作登录用途）；③ 你的账号与订阅状态、设备安装标识的关联信息，用于校验与恢复订阅权益。我们不收集姓名、手机号、精确位置、通讯录、健康与训练数据——这些始终只存在你的设备上。
3. 登录方式。支持「通过 Apple 登录」与「邮箱验证码登录」。验证码 60 秒可重发、短期有效；传输全程使用加密连接（TLS）。
4. 数据如何存储与保护。验证码以加盐哈希（PBKDF2）存储，不可还原；登录凭证在服务端仅保存哈希值；邮箱验证码由阿里云邮件推送服务发送（仅收件地址与验证码内容）。我们不会出售你的账号信息，也不用于广告。
5. 删除账号。在 「设置 → 账号」中即可一键删除，无需联系我们。删除后：你的账号立即进入停用与删除流程，登录状态即时失效；30 天冷静期后邮箱与账号标识从生产数据库删除（期间若重新登录可撤销删除）；绑定该账号的订阅记录将解除身份关联（仅保留无身份关联的匿名交易统计用于对账与税务合规）。你也可以随时通过 Apple「隐藏邮箱」的中转地址停用转发。
6. 订阅与账号的关系。购买与恢复购买由 Apple 处理，我们不会从 Apple 获得你的付款卡号。若你登录了账号，订阅权益随账号跨设备恢复；未登录时权益绑定在本机安装上，卸载重装后通过账号或 Apple 的「恢复购买」找回。
八、联系方式

1. What we collect
The core app works without an account. If you choose to create one, we collect only what is described in "7. Account" below. Diet records, training times, and phase plans are stored on this device only and are never uploaded to our servers.
2. Photo recognition & photo handling
1) The photo-scan feature transmits the photo content to a large-model provider (Zhipu AI; its generative-AI service is filed with the authorities) solely to recognize foods and ingredients — for no other purpose.
2) Photos never reach our servers, are never saved to your photo library, and are never used for advertising; they are used temporarily during recognition only and are deleted once recognition finishes (success or failure).
3) Photo recognition is your choice: switching to manual entry transmits no photos at all.
4) Advice and judgments are not generated by AI — they are computed on-device by a deterministic rule engine based on published literature.
3. AI processing of ingredient text
Recognized ingredient text is sent to a large-model provider for structured extraction (ingredient text only, no identity information); profiling and timing advice are computed by the on-device rule engine.
4. Anonymous usage statistics
When enabled (default on; can be turned off in Settings at any time), we collect identity-unrelated usage events (e.g., feature taps) to improve the product; when off, nothing is reported.
5. Quota
The free scan quota is accounted on this device and is not linked to your identity.
6. Minors
The app does not provide calorie-restriction advice to minors.
7. Account (optional)
1. Creating an account is your choice. Scanning, decisions, and local records all work without one. An account is only needed to restore your subscription across devices and keep cloud-side entitlements.
2. What we collect. When you create an account: (a) your email address (for sign-in verification and account-security notices); (b) if you use Sign in with Apple, the account identifier returned by Apple (a random unique ID) and the email you choose to share — including a private Apple relay address, used solely for sign-in; (c) the association between your account, subscription status, and an install identifier, used to verify and restore entitlements. We do not collect your name, phone number, precise location, contacts, or health/training data — those never leave your device.
3. Sign-in methods. Sign in with Apple, or email verification codes. Codes are short-lived and resendable after 60 seconds; all traffic is encrypted (TLS).
4. Storage & protection. Verification codes are stored as salted hashes (PBKDF2) and cannot be reversed; server-side credentials are kept only as hashes; codes are delivered via Alibaba Cloud DirectMail (recipient address and code content only). We never sell account data or use it for advertising.
5. Deleting your account. Use Settings → Account → Delete Account — no need to contact us. Your account is deactivated immediately and sign-in is revoked right away; after a 30-day grace period your email and identifiers are deleted from production databases (signing in again during the window cancels the deletion). Subscription records tied to the account are de-identified; only anonymized transaction totals are retained for accounting and tax compliance. You may also stop email forwarding at any time via Apple's Hide My Email.
6. Subscriptions and your account. Purchases and restores are handled by Apple; we never receive your payment card details. Signed in, your entitlements restore on any device; signed out, they are bound to this installation and can be recovered via your account or Apple's "Restore Purchases".
8. Contact
Questions about this policy: reach us via the support link on the App Store page.
This app provides general reference information based on publicly available sports-nutrition consensus and literature. It is not medical advice, diagnosis, or treatment, and does not replace guidance from a physician, registered dietitian, or qualified coach.
Timing suggestions are broad ranges for reference, not individual plans; no body-composition or performance results are promised.
If you are under 18, pregnant or breastfeeding, have a metabolic condition (e.g., diabetes) or a history of eating disorders, consult a professional first; the app does not provide calorie-restriction advice to minors.
Listen to your own tolerance — stop immediately and seek medical care if you feel unwell.
Data: diet records, training times, and phase plans stay on this device only; anonymous usage statistics are on by default and can be turned off in Settings at any time.
Ingredient data is extracted automatically from photos and may contain errors — refer to the actual package label.
