Driftlet（包名 com.yglllzcw.driftlet）由成都知源创芯科技有限公司（Chengdu Zhiyuan Chuangxin Technology Co., Ltd，以下简称“我们”）开发和运营。简单来说：Driftlet 不收集你的任何个人数据。下面是具体说明。
Driftlet 的所有声音都由应用在你的手机上实时合成，不需要联网，也不会把任何内容上传给我们。应用没有申请网络访问权限，不包含账号系统。
应用在你的设备上保存少量设置：上次选择的场景、调音板的位置、外观（白天 / 夜间）、闹钟时间、免费试用的开始时间，以及是否已购买完整版。这些设置可能随 Android 系统备份保存到你自己的 Google 账号中（由 Google 处理），我们无法访问。
购买完全通过 Google Play 完成，付款信息由 Google 处理，我们拿不到你的银行卡、支付账号或 Google 账号信息。应用会向你手机上的 Google Play 查询这次购买是否有效，这个过程在你的设备和 Google Play 之间进行，不经过我们的服务器。Google 对相关数据的处理适用 Google 的隐私政策。
Driftlet 不使用麦克风、位置、通讯录、相机，也不读取你的健康或运动数据。
卸载应用即可删除第 2 条中的全部本地数据。
Driftlet 不面向 13 岁以下儿童，我们也不会收集儿童的个人信息。
本政策如有变更，会在本页面更新并修改生效日期。如果将来新增需要处理个人数据的功能，我们会先更新本政策并在应用内提示。

Driftlet (package com.yglllzcw.driftlet) is developed and operated by Chengdu Zhiyuan Chuangxin Technology Co., Ltd (“we”). In short: Driftlet collects no personal data. The details follow.
Every sound in Driftlet is synthesized live on your device. It needs no internet connection and sends nothing to us. The app does not request network access and has no accounts.
The app keeps a few settings on your device: the last scene you picked, tuning-pad positions, appearance (light / dark), the alarm time, when your free trial started, and whether you bought the full version. These settings may be included in Android backup to your own Google account (handled by Google); we cannot access them.
Purchases are made entirely through Google Play, and payment details are handled by Google. We never receive your card, payment account or Google account details. The app asks Google Play on your device whether the purchase is valid; this happens between your device and Google Play and does not involve our servers. Google’s privacy policy applies to Google’s processing.
Driftlet does not use the microphone, location, contacts or camera, and does not read health or activity data.
Uninstalling the app deletes all local data described in section 2.
Driftlet is not directed at children under 13, and we do not collect personal information from children.
We will post any changes on this page and update the effective date. If we ever add a feature that processes personal data, we will update this policy first and tell you in the app.
