使用条款
本页说明 Footprint 的订阅与内建识别服务。App 许可同时适用 Apple 标准最终用户许可协议；你的法定消费者权利不受影响。
订阅与试用
高级版提供自动续订的月付、年付方案，不提供一次性或终身购买。实际价格、周期和试用资格以 App Store 购买确认页面为准。符合资格时可获得 3 天免费试用；同一订阅组的试用资格由 Apple 判定，不是每个方案都能重复试用。
试用结束后，订阅按所选周期和确认价格续订。你可以在 Apple 账户的订阅设置中取消或更改方案。为避免下一期扣费，请提前至少 24 小时取消；删除 App 不会取消订阅。退款请求通过 Apple 的退款渠道处理。
内建识别服务
每台设备无需订阅即可免费完成 3 次餐食分析，识别失败或照片中没有食物不扣次数，免费次数不会每日重置。免费次数用尽后需要有效高级订阅。每笔订阅每天最多可使用 30 次识别，按首次使用时确定的时区自然日重置；未使用次数不累计。服务需要联网，可能受维护、供应商或连接状况影响。App 内可查看实际可用状态。
估算与记录
照片识别提供热量和营养估算，食物重量、做法及图片质量都可能影响结果。它用于日常记录，不能代替专业医疗或营养诊断。请核对并按实际份量调整记录。活动与路线展示取决于你提供的数据和系统授权。
合理使用
请勿绕过额度、滥用接口、干扰服务或提交违法内容。仅提交你有权使用的照片和资料。功能介绍展示 App 的整体能力，不表示每项功能均为高级版独占。

Terms of Use
This page describes Footprint subscriptions and built-in recognition. The app is also licensed under Apple's Standard EULA. Your statutory consumer rights are unaffected.
Subscriptions and trials
Premium offers auto-renewing monthly and annual plans, with no lifetime or one-time purchase. The App Store confirmation screen determines the actual price, period and eligibility. Eligible customers may receive a three-day free trial. Apple determines eligibility within the subscription group; switching plans does not provide a repeat trial.
After the trial, the subscription renews at the confirmed price and period. Manage or cancel it in your Apple Account subscription settings. Cancel at least 24 hours before the next renewal to avoid the next charge. Deleting the app does not cancel a subscription. Refund requests are handled through Apple.
Built-in recognition
Each device can complete 3 meal estimates without a subscription. Failed estimates and non-food photos do not consume free uses, and free uses do not reset each day. After those uses, built-in recognition requires an active Premium subscription and allows up to 30 recognitions per subscription per calendar day. The day uses the time zone fixed at first use; unused requests do not roll over. A connection is required, and maintenance, provider availability or connectivity can affect service. Check the app for current availability.
Estimates and records
Photo recognition estimates calories and nutrients. Food weight, preparation and photo quality affect the result. It supports everyday logging and is not a substitute for medical or nutritional diagnosis. Review estimates and adjust portions. Activity and route displays depend on your data and system permissions.
Fair use
Do not bypass quotas, abuse interfaces, interfere with the service or submit unlawful content. Only submit photos and information you have the right to use. Product feature descriptions show the app's overall capabilities, not a promise that every feature is exclusive to Premium.
