存在你这台设备的东西What stays on your device
学习进度、设置、考试资料（版本、州、每天几分钟、面试日期）存在你的浏览器里。我们不问护照号码、社安号码、A-Number 或任何身份证件资料。Your progress, settings and test details (version, state, minutes a day, interview date) are stored in your browser. We never ask for passport, Social Security, A-Number or any ID numbers.
买了完整版之后After you buy Complete
付款由 Stripe 处理，我们只收到你的 email 与购买记录，拿不到卡号。你的账号存在 We Live in USA 共用的会员账号里（跟其他 We Live in USA 网站同一个账号）。登录后，学习进度会同步一份到你的账号，换设备也看得到。Stripe handles payment; we receive your email and the purchase record, never your card number. Your account lives in the shared We Live in USA member account. When signed in, a copy of your progress syncs to your account so other devices can see it.
麦克风与语音Microphone and voice
开口答题用的是你浏览器内置的语音辨识：Chrome 会把声音送到 Google、Safari 送到 Apple 的语音服务转成文字，这段不经过我们。我们只拿到转好的文字，用来比对答案，不录音、不保存声音，也不拿来训练任何模型。不想用麦克风，可以改用打字或自己判断。Speaking practice uses your browser's built-in speech recognition: Chrome sends audio to Google and Safari to Apple to turn it into text; that doesn't pass through us. We only get the text to check your answer; we don't record or keep audio or use it to train any model. You can type instead.
发音Pronunciation audio
英文发音用预先录好的音档；没有音档的句子用你设备内置的语音念。有些浏览器会把要念的句子交给它自己的语音服务。Pronunciation uses pre-made audio files; sentences without a file use your device's built-in voice, which some browsers hand to their own speech service.
广告与追踪Ads and tracking
练习页面没有广告。我们不卖、不出租你的资料。The practice pages carry no ads. We don't sell or rent your data.
删除数据Deleting your data
在「设置」可以清除这台设备的学习记录，登录时也可以删除同步在账号里的进度。要删除整个账号，请用账号 email 写信到 weliveinusa.com@gmail.com；因为账号是 We Live in USA 各站共用的，删除后其他站的购买也会一起失效，我们会先跟你确认。In Settings you can clear progress on this device and, when signed in, delete the progress synced to your account. To delete the whole account, email weliveinusa.com@gmail.com from that address; because the account is shared across We Live in USA sites, purchases on other sites go too, so we'll confirm with you first.
