Privacy Policy & Support

最后更新：2026 年 9 月 8 日 · 适用版本 1.0 起

Last updated: September 8, 2026 · Applies to version 1.0 and later

一句话总结

简单笑笑没有账号体系、没有服务器、没有广告，也没有接入任何第三方统计或分析工具。你记录的报销数据完整保存在你自己的设备上，我们看不到，也无法看到。

一、我们收集哪些信息

1. 位置信息（仅在你授权后）

为了显示你所在国家、城市与当地时区的时间，App 会在你授权后获取一次设备坐标（经纬度），并将坐标发送给第三方地理编码服务 BigDataCloud，换取国家名、城市名与时区标识。

坐标只在发起查询的那一刻使用，我们不建立服务器，因此不会在任何后台留存你的坐标。
查询结果（国家、城市、时区、坐标）会缓存在你设备本地，用于下次启动时快速显示。
位置权限是可选的。拒绝授权后 App 依然可以正常使用，只是仅显示中国时区的时钟。
App 只在回到前台时刷新一次定位，不在后台持续追踪你的位置。

2. 只存在你设备上、从不上传的数据

数据	说明
报销记录	事由、金额、消费日期、备注、报销状态
主页组件	你添加了哪些卡片、以及它们的排列顺序
语言与主题	界面语言、深色 / 浅色偏好
位置缓存	上一次解析出的国家、城市与时区

以上全部通过系统的 UserDefaults 保存在 App 沙盒内，不会离开你的设备。

3. 我们不收集的信息

不收集姓名、邮箱、手机号等任何可识别身份的信息（App 根本没有注册登录）。
不收集通讯录、照片、麦克风、摄像头、健康数据。
不收集广告标识符（IDFA），不做任何形式的跨 App 或跨网站追踪。
不接入任何第三方统计、崩溃收集或广告 SDK。

二、关于设备信息卡片

「设备信息」卡片会读取系统型号、系统版本、网络类型、上下行速率、内存、CPU、磁盘容量与电池电量。这些数据仅在你的屏幕上实时显示，既不会被保存，也不会被发送到任何地方。

三、第三方服务

App 只调用一个外部服务：

服务	BigDataCloud 反向地理编码
接口	`api.bigdatacloud.net`（全程 HTTPS）
发送内容	经度、纬度、界面语言代码
用途	换取国家名、城市名与时区标识
隐私政策	bigdatacloud.com/privacy-and-cookie-policy

该请求不携带任何账号、设备标识或广告标识，对方无法据此识别到你个人。

四、数据保留与删除

由于所有数据都存放在设备本地，删除 App 即会一并清除全部报销记录与偏好设置，无需另行联系我们。请注意此操作不可恢复，重要记录建议先自行备份。

五、儿童隐私

本 App 不面向 13 周岁以下儿童设计，也不会有意收集儿童的任何个人信息。

六、政策变更

如果隐私政策发生实质性变化，我们会更新本页顶部的「最后更新」日期。建议你在版本更新后回来查看。

七、联系与支持

使用中遇到问题、发现 Bug，或对隐私有任何疑问，欢迎邮件联系，我会尽快回复：

In one sentence

SimpleSmile has no accounts, no servers, no ads, and no third-party analytics of any kind. The expense records you enter stay entirely on your own device — we cannot see them.

1. What we collect

1.1 Location (only with your permission)

To show your country, city, and local time zone, the app requests your device coordinates once after you grant permission, then sends those coordinates to the third-party geocoding service BigDataCloud to obtain a country name, city name, and time zone identifier.

Coordinates are used only at the moment of the lookup. We operate no servers, so nothing is retained on any backend.
The result (country, city, time zone, coordinates) is cached locally on your device for faster startup.
Location access is optional. If you decline, the app still works and simply shows the China time zone clock.
Location refreshes only when the app returns to the foreground. There is no background tracking.

1.2 Data that stays on your device and is never uploaded

Data	Details
Expense records	Description, amount, date, note, reimbursement status
Home widgets	Which cards you added and their order
Language & theme	Interface language and light / dark preference
Location cache	Last resolved country, city, and time zone

All of the above is stored via the system UserDefaults inside the app sandbox and never leaves your device.

1.3 What we never collect

No name, email, phone number, or any other identifying information — the app has no sign-up at all.
No contacts, photos, microphone, camera, or health data.
No advertising identifier (IDFA) and no cross-app or cross-site tracking of any kind.
No third-party analytics, crash reporting, or advertising SDKs.

2. About the Device card

The Device card reads your model, OS version, network type, throughput, memory, CPU, disk capacity, and battery level. This information is displayed live on your screen only — it is never stored and never transmitted anywhere.

3. Third-party services

The app calls exactly one external service:

Service	BigDataCloud reverse geocoding
Endpoint	`api.bigdatacloud.net` (HTTPS only)
Sent	Latitude, longitude, interface language code
Purpose	Resolve country name, city name, and time zone
Their policy	bigdatacloud.com/privacy-and-cookie-policy

The request carries no account, device identifier, or advertising identifier, so you cannot be personally identified from it.

4. Retention and deletion

Because everything is stored locally, deleting the app removes all expense records and preferences at once — no need to contact us. Note that this is irreversible, so please back up anything important first.

5. Children's privacy

This app is not directed at children under 13 and does not knowingly collect any personal information from children.

6. Changes to this policy

If this policy changes materially, we will update the "Last updated" date at the top of this page. Please check back after app updates.

7. Contact and support
