腕词隐私政策
更新日期：2026 年 10 月 20 日
账号与学习记录
首次使用须在 iPhone 上通过 Apple 登录。我们接收经 Apple 验证的账号标识，不接收 Apple 密码，也不请求姓名或电子邮件。词书、每日目标、学习时间、记忆评价、生词与收藏先保存在设备上。手机与配对手表之间的同步免费，包括自定义词书中的单词、释义、音标和标签，以及冲刺日期、训练评分和易错记录。云端学习档案同步需要有效 VIP；有效 VIP 期间，上述记录通过 HTTPS 备份到腕词独立的账号。免费账号不读写云端学习档案，VIP 到期或撤销后停止云端同步，已有本机记录保留。内置词库随 App 离线提供，不上传；发音由 Apple 系统在设备上合成。
配对的 Apple Watch 通过 Apple 的设备连接接收账号身份和学习记录；首次授权须连接已登录的 iPhone，之后可离线学习。离线修改将在设备重新连接时尝试同步。我们不将腕词数据与其他 Wristlab App 的产品数据混用，也不用于广告、跟踪或出售。
控制与删除
你可以在 iPhone 的账号菜单中退出登录或删除此 App 的账号数据。退出登录会清除本机及连接后手表上的账号学习记录。VIP 用户退出前会先同步最新记录；同步失败时保留账号及本机记录。免费用户退出前会提示尚未云端备份的本机记录将被移除，可取消退出以保留记录。已有服务端备份保留，以便再次登录并具有有效 VIP 时恢复。删除账号会删除腕词服务端账号数据并清除本机记录；离线手表上的副本在下次连接后清除。卸载 App 本身不会删除服务端备份。基础学习、词书、计划和学习报告永久免费，无试用期限，离线时也可使用本地词库并保存学习记录。表盘组件、云端学习档案同步和专项训练需要有效 VIP，不提供免费试用。
会员与购买
购买由 Apple 处理。我们向腕词账号所在区域的服务端提交经 Apple 验证的签名交易，保存商品、交易身份、环境、有效期、撤销及账号归属，用于恢复会员与核对权益，不包含学习内容或支付卡信息。月度和年度 VIP 自动续订，永久 VIP 为一次性购买。删除账号会清除腕词的购买关联，以及历史版本保存的试用和优惠记录，但不会取消 Apple 订阅；可在 Apple 的订阅管理中取消续订。历史试用记录不限制基础学习，也不授予当前 VIP 权益。离线时，付费功能按已核实且仍有效的会员权益提供。
English summary
Sign in with Apple is required on iPhone before first use. We receive a verified account identifier, never your Apple password, and do not request your name or email. Your selected book, daily goal, study times, recall ratings, unknown words and favorites are kept locally. Sync between your iPhone and paired Watch is free, including imported words, meanings, phonetics, tags, exam dates and training records. Cloud study sync requires active VIP access and backs up these records over HTTPS to a Wrist Words account isolated from other Wristlab apps. Free accounts do not read or write cloud study archives. Cloud sync stops when VIP expires or is revoked; existing local records remain. The bundled vocabulary stays on the device; pronunciation uses Apple system speech. A paired Watch receives account-bound records from the signed-in iPhone and can study offline after setup. We do not sell data or use ads or tracking.
The iPhone account menu lets you sign out or delete this App's account data. Signing out clears account study records on this device and, when connected, the paired Watch. VIP users sync their latest records before signing out; a sync failure keeps the account and local records in place. Free users are warned that local records without cloud backup will be removed and can cancel to keep them. Existing server backups remain available after signing in again with active VIP access. Deleting the account removes the server backup and clears local records; an offline Watch clears its copy when it reconnects. Uninstalling the App does not delete the server backup. Basic study, wordbooks, plans and study reports are free indefinitely, with no trial deadline. You can study offline and save records locally. Watch complications, cloud study sync and focused training require active VIP access and have no free trial.
Monthly and annual VIP renew automatically; lifetime VIP is a one-time purchase. Apple handles payment. The iPhone sends Apple-verified signed transactions to the service for the account's region; the service stores the product, transaction identity, environment, expiry, revocation and account ownership for entitlement checks and restoration. This does not include study content or payment card details. Deleting your account removes this App's purchase associations and any trial or offer records retained from earlier versions, but does not cancel Apple subscriptions. You can cancel renewal in Apple's subscription settings. Historical trials neither limit basic study nor grant current VIP access. Paid features work offline while a verified VIP entitlement remains valid.

界面语言
登录后，iPhone 会随账号请求上报此 App 实际使用的界面语言。服务端按此 App 与账号保存语言代码及最后一次语言变化的时间，用于本地化支持和问题排查。它不包含记录内容，不用于广告或跨 App 跟踪，也不能确认你的国籍。删除此 App 的账号时会一并删除；退出登录停止上报，但保留已有值。
Interface language
After sign-in, your iPhone reports this App's active interface language with account requests. Our service stores the language code and the time of its last change for this App and account to support localization and troubleshooting. It contains no record content and is not used for advertising, cross-app tracking, or determining nationality. Deleting this App's account removes it. Signing out stops reporting while retaining the existing value.
首次使用统计
iPhone 会向我们的第一方统计服务发送登录、学习计划设置、购买和进入首页的阶段、结果、前台耗时、版本、实际界面语言及 App Store 国家或地区，用于发现首次使用中的问题。我们使用此 App 专属的随机安装、运行和流程标识；登录后可关联此 App 的账号。经 Apple 验证的 App 专属匿名下载标识和原始下载时间用于区分首次下载、更新、重装及购买转化，正式、TestFlight 和调试数据分开。不会采集所选词书、每日目标数值、单词或学习内容，不用于广告或跨 App 跟踪。
离线事件先保存在受保护且不备份的本机队列中，联网后重试；上报失败不影响正常使用。匿名行为及来源信息保留 90 天，删除此 App 的账号时清除关联行为；退出或换号后不将旧流程归入新账号。手表及表盘组件不新增此类网络上报。
First-use analytics
The iPhone sends first-use stages and outcomes for sign-in, study-plan setup, purchases and reaching the home screen to our first-party analytics service, together with foreground duration, version, active interface language and App Store country or region. App-specific random installation, run and flow identifiers may be linked to this App's account after sign-in. An Apple-verified App-specific anonymous download identifier and original download time distinguish first downloads, updates, reinstalls and purchase conversion. Production, TestFlight and debug data remain separate. We do not collect selected books, daily-goal values, words or study content for analytics, or use it for advertising or cross-app tracking.
Offline events stay in a protected local queue excluded from backups and retry when online; analytics failures do not block use. Anonymous events and source information are retained for 90 days. Account deletion removes associated events; signing out or switching accounts does not assign an old flow to the new account. The Watch and complications do not add analytics network requests.
