MathPace helps you practice for the SAT Math section. We built it so your data stays on your device.
Nothing that identifies you. MathPace has no accounts, no advertising and no tracking, and your practice data never leaves your device. The only thing the app sends is a record of purchases, described under Purchases below.
If you email us, we receive your email address and your message. We use them only to reply, and we'll delete them if you ask.
Deleting the app removes this data from your phone. If you back up your phone, it may be included in that backup, which is handled by Apple or Google, or by your computer.
Daily reminders are optional and are scheduled locally on your phone. If you start the free trial, the app also schedules a local reminder before the trial ends. Nothing about these notifications is sent to us.
MathPace Premium is sold through Apple's App Store on iPhone and through Google Play on Android. Apple or Google processes the payment; we never see your payment details, Apple Account or Google Account. Their privacy policies apply to that process. They may also give us combined sales figures and, if you chose to share them with developers, crash reports. These don't identify you to us.
When you buy or renew Premium, the app sends a record of that purchase (which plan, the price and currency, the dates, and the store's transaction details) to RevenueCat, a service that keeps our sales records. It is filed under a random ID the app makes, not your name, email, Apple Account or Google Account. We use it to see how many people subscribe, start trials and renew, and to check that purchases are genuine. RevenueCat processes it for us under its own privacy policy (revenuecat.com/privacy) and does not use it for advertising. Your practice progress is never sent.
MathPace is not directed at children under 13. The app collects no personal information from anyone, including children; a purchase record carries only a random ID.
If this policy changes, we will update this page and the date above.

MathPace 帮你练习 SAT 数学。我们的原则是：你的数据留在你的设备上。
不收集任何能识别你的信息。MathPace 没有账号、没有广告，也不做任何追踪；你的练习数据从不离开你的设备。App 唯一发送的是购买记录，见下面的「购买」。
如果你给我们发邮件，我们会收到你的邮箱地址和邮件内容，只用于回复你；你要求时我们会删除。
删除 App 就会把这些数据从你的手机上删掉。如果你备份手机，这些数据可能包含在备份里，备份由苹果、Google 或你的电脑保管。
每日提醒是可选的，在你的手机本地安排。如果你开始免费试用，App 还会在本地安排一条试用到期前的提醒。这些通知的内容都不会发送给我们。
MathPace Premium 在 iPhone 上通过苹果 App Store 购买，在安卓手机上通过 Google Play 购买，由苹果或 Google 处理付款。我们看不到你的付款信息、Apple 账户或 Google 账号，这部分适用它们各自的隐私政策。它们还可能向我们提供汇总的销售数据，以及你同意与开发者共享的崩溃报告，这些信息不会让我们识别出你。
你购买或续订 Premium 时，App 会把这笔购买的记录（哪个方案、价格和币种、日期，以及商店的交易信息）发送给 RevenueCat，一家帮我们保存销售记录的服务商。记录挂在 App 生成的一个随机 ID 下，不包含你的姓名、邮箱、Apple 账户或 Google 账号。我们用它了解有多少人订阅、开始试用和续订，并核实购买是真实的。RevenueCat 按它自己的隐私政策（revenuecat.com/privacy）替我们处理这些记录，不会用于广告。你的练习进度从不发送。
MathPace 不面向 13 岁以下的儿童。App 不收集任何人（包括儿童）的个人信息；购买记录只带一个随机 ID。
如果这份政策有变化，我们会更新本页和上面的日期。
