1. 服务与联系
EasySwing 提供网球视频辅助分析、报告、追问及训练记录。支持：support_easyswing@yeah.net。功能及价格以 App 和 Apple 购买页面为准。
2. 账号与记录
云端功能使用 Apple 登录，请保护账号。本机视频和历史主要保存在当前设备及账号空间，没有完整历史云同步；设备损坏、删除 App 或更换设备可能导致丢失，短期任务恢复不等于备份。退出登录保留该账号的本机记录，重新登录同一账号可访问仍保留的记录。手动训练可编辑；Apple 健康原始训练不通过本 App 修改。
3. AI 与素材
正式版 AI 功能通过 EasySwing 后端接入 OpenAI 官方 API。你无需自行购买 OpenAI 订阅；EasySwing 的购买、支持与账号由本 App 提供。
AI 可能误判或遗漏，结果受角度、遮挡及画质影响，仅供训练参考；不保证提高成绩或避免受伤，不构成医疗诊断或治疗。缺少证据时，球速、旋转、拍面或三维角度不能作为测量值。出现疼痛应停止训练并寻求专业帮助。
使用 AI 前单独征求数据共享同意。你保留素材权利，并允许我们及已披露处理方为完成请求处理必要内容。请取得拍摄和分享许可；不得提交违法、侵权或无关敏感内容，不得冒用账号、篡改交易、绕过额度或攻击服务。为保护服务可限制滥用，并通过支持邮箱受理异议。
4. 购买与额度
App 商品页展示额度；Apple 购买确认页显示价格、周期和自动续订信息。首购优惠资格由 Apple 按同一订阅组判定，最终金额以购买确认页为准。订阅按周期自动续订；年度订阅按年付款、按订阅月发放额度，未用周期额度不结转。次数包为一次性购买，不要求同时订阅，不因订阅到期失效。
已付费订阅周期内，保留购买时约定的分析额度及每份报告附带追问次数；年度订阅在该付费年内按原约定发放每月额度。后续方案调整最早从下一次续费周期生效，并提前通过站内消息或其他合理方式告知，你可在生效前取消续订。价格调整遵循 Apple 适用的通知和同意规则。阅读或确认通知不自动改变当前权益，也不代替购买或续费所需的同意。
免费会员自首次注册日起，每个注册月享 1 次分析，不累计。有效订阅期间使用订阅方案的每月分析额度，不额外叠加免费会员额度。周期按服务端 UTC 注册时间计算；当月无对应日期时取月末，下个周期仍按原注册日计算。重新登录、恢复购买或以同一身份重新注册不会重置当月已用额度。分析依次使用免费、订阅和已购次数；追问先使用报告自带次数，再使用全局次数。技术失败或无法形成诊断不扣分析次数，同一任务恢复不重复扣次。退款、撤销或交易调整可能相应调整权益及未用额度，以 Apple 核验结果为准。
可在 Apple 订阅设置取消续订，取消不自动退款；退款由 Apple 处理。删除账号不取消订阅。依法不可排除的消费者权利不受本条款限制。
5. 数据、可用性与更新
信息处理和接收方见隐私政策。可在 App 删除账号及视频、撤回未来 AI 分享授权；最少的账务与安全记录可能依法保留。服务可能因维护、网络或第三方故障中断，请保管重要素材。重要条款变化会告知并在需要时重新征求同意；中英文切换不改变条款版本。
1. Service and contact
EasySwing provides assisted tennis-video analysis, reports, follow-ups and workout records. Support: support_easyswing@yeah.net. Features and prices are shown in-app and on Apple's purchase screen.
2. Account and records
Cloud features use Sign in with Apple; protect your account. Videos and history are primarily stored in the current device's account space without full-history cloud sync. Device loss, app deletion or replacement may lose records; temporary job recovery is not backup. Signing out preserves local account records; signing back into the same account accesses records still available. Manual workouts are editable; this app does not modify original Apple Health workouts.
3. AI and content
The production AI features use the official OpenAI API through the EasySwing backend. You do not need your own OpenAI subscription. EasySwing provides the app's purchases, support and account service.
AI can be wrong or incomplete; angle, occlusion and image quality affect results. Advice is for training reference, does not guarantee improvement or injury prevention, and is not medical diagnosis or treatment. Unsupported ball speed, spin, racket-face or 3D angles are not measurements. Stop training if you experience pain and seek professional help.
AI sharing requires separate consent. You retain content rights and permit us and disclosed processors to process necessary content for your requests. Obtain recording and sharing permissions. Do not submit unlawful, infringing or unrelated sensitive content, impersonate accounts, alter transactions, bypass allowances or attack services. We may restrict abuse; contact support to dispute a restriction.
4. Purchases and allowances
The in-app product page shows allowances; Apple's purchase sheet shows price, period and renewal information. Apple determines introductory-offer eligibility per subscription group; confirm the final amount on its purchase sheet. Subscriptions renew automatically; annual plans are billed yearly with allowances issued each subscription month. Unused periodic allowances do not roll over. Packs are one-time purchases, require no subscription and do not expire when a subscription ends.
During an already-paid subscription period, we preserve the agreed analysis allowance and included questions per report. Annual plans retain their agreed monthly allowance throughout that paid year. Later plan changes take effect no earlier than the next renewal period, with advance notice through the inbox or another reasonable channel; you may cancel renewal before they take effect. Price changes follow Apple's applicable notice and consent rules. Reading or acknowledging a notice does not change current benefits or replace consent required for a purchase or renewal.
Free members receive 1 analysis per month anchored to their original registration time in UTC, with no rollover. During an active subscription, the subscription’s monthly analysis allowance applies instead of the free-member allowance. A missing anniversary day is clamped to that month’s last day; later months retain the original day. Signing in, restoring purchases or re-registering with the same identity does not reset usage. Analyses use free, subscription and purchased allowances in that order. Questions use report-included questions before global packs. Technical failures or results without a diagnosis do not consume an analysis; recovery of the same job does not consume another. Refunds, reversals and transaction adjustments may adjust entitlements and unused allowances according to verified Apple records.
Cancel renewal in Apple's subscription settings; cancellation does not automatically refund purchases. Apple handles refunds. Deleting your account does not cancel subscriptions. Non-waivable consumer rights remain unaffected.
5. Data, availability and changes
See the Privacy Policy for processing and recipients. Delete accounts or videos and withdraw future AI sharing in-app. Minimal billing and security records may remain as legally necessary. Maintenance, networks or third-party failures may interrupt service; keep important source material. Material terms changes receive notice and renewed consent where necessary. Switching language does not change the terms version.
