PrincessMath Privacy

Effective date: October 10, 2026

The short version

PrincessMath is a math game that runs in your browser. Almost everything stays on your device. The only thing our server receives is anonymous counts of how the game is used. We do not know who is playing.

Who we are

PrincessMath is a student project published by Cyanworld Global Services LLC, Irvine, California, USA. Questions: support@cyanworld.com.

What stays on your device

The name your child types, the princess and buddy they pick, and the language.
Which levels are finished, the stars earned, and how each kind of question went.
Any voice recordings a parent makes in Parent settings.

These are saved in your browser's storage on this device. They are never sent to us. Clearing your browser's data for this site, or removing the game from your home screen, erases them. Parent settings also has a button that erases progress; recordings are deleted one by one in the same screen.

The microphone

The game uses the microphone only when a parent taps Record in Parent settings. The recording is saved on the device and played back there. It is not uploaded.

Reading aloud

Questions are read aloud by the voice built into your device. The game does not send text to us for this.

What our server receives

Anonymous counts of how the game is used, and nothing else. For example: how many devices opened the game, and how many started and finished levels.

Each count is a total. A message from the game never contains a name, an account, a device identifier, or anything your child typed, and we do not work out where you are.

Like any website, our server sees the internet address a request comes from. For these counts it holds that address in memory for the rest of the day, only to stop one network from inflating the totals, and never writes it to disk. Our web server keeps no access log for this site.

What we do not do

No accounts. No cookies. No advertising. No third-party analytics or trackers. The page loads nothing from other companies; even the font comes from this site.

Children

PrincessMath is made for young children. We do not collect personal information from them. A parent who has a question can write to support@cyanworld.com.

Changes

If the game starts keeping anything else, this page will be updated first and the date above will change.

公主数学隐私说明

生效日期：2026 年 10 月 10 日

简单说

公主数学是一个在浏览器里运行的数学游戏。几乎所有东西都留在你的设备上。我们的服务器只收到一样东西：关于游戏使用情况的匿名计数。我们不知道是谁在玩。

我们是谁

公主数学是一个学生项目，由 Cyanworld Global Services LLC（美国加利福尼亚州尔湾）发布。有问题请写信到 support@cyanworld.com。

留在你设备上的

孩子输入的名字、选的公主和伙伴、语言。
过了哪些关、得了几颗星、每一类题答得怎么样。
家长在“家长设置”里录的语音。

这些保存在这台设备的浏览器存储里，不会发送给我们。清除浏览器里这个网站的数据，或者把游戏从主屏幕上删掉，就会把它们清掉。“家长设置”里还有一个清除进度的按钮；录音在同一个页面里一条一条删除。

麦克风

只有家长在“家长设置”里点“录音”时，游戏才会使用麦克风。录音保存在设备上，也在设备上播放，不会上传。

朗读

题目由设备自带的语音朗读。游戏不会为此把文字发送给我们。

我们的服务器收到什么

只有关于游戏使用情况的匿名计数，没有别的。例如：有多少台设备打开了游戏，有多少开始和完成了关卡。

每一项都只是一个总数。游戏发来的消息里不包含名字、账号、设备标识，也不包含孩子输入的任何内容；我们也不推断你在哪里。

和任何网站一样，我们的服务器能看到请求来自哪个网络地址。对这些计数，服务器只在当天把这个地址放在内存里，用来防止同一个网络把总数刷高，不会写入磁盘。我们的网页服务器不为这个网站保留访问日志。

我们不做的事

没有账号。没有 cookie。没有广告。没有第三方统计或跟踪。页面不从别的公司加载任何东西，连字体都来自本站。

儿童

公主数学是为年幼的孩子做的。我们不向他们收集个人信息。家长有问题可以写信到 support@cyanworld.com。

变更

如果游戏以后开始保留其他内容，会先更新这个页面，并修改上面的日期。
