一字一乐 隐私政策

生效日期：2026 年 10 月 26 日

「一字一乐」是一款帮助孩子练习书写汉字的 App。我们不收集、不上传、不分享任何个人信息。

我们不收集任何信息

• 不需要注册或登录，没有账号。
• 不收集姓名、年龄、邮箱、电话、位置、照片、通讯录或设备标识符。
• 没有广告，没有第三方统计、分析或追踪工具，也不包含任何第三方 SDK。
• App 运行时不联网。唯一的网络活动是购买和恢复购买，由 Apple App Store 处理。

保存在设备上的内容

为了记住孩子学到哪里，App 会在本机保存以下内容，这些内容不会离开设备：

• 学习进度、学习记录和复习安排；
• 错字本（哪些字写错过、错在哪一笔）；
• 作业页上孩子写下的笔迹；
• App 内的设置（每天学几个字、语音、语速等）。

删除 App 会同时删除以上全部内容。家长也可以在 App 的「家长」页面删除单页作业。

备份文件

家长可以在「家长」页面主动导出一个备份文件，并自行选择保存位置（例如「文件」App 或 iCloud 云盘）。这个文件只在家长自己的设备和账户里，我们收不到，也无法访问。

购买

所有购买（包括 3 天免费试用）都通过 Apple App Store 完成。我们收不到任何付款信息或 Apple 账户信息。

语音

读字和语音提示使用 iOS 系统自带的离线语音合成。App 不录音，不使用麦克风或摄像头。

儿童隐私

本 App 为儿童设计。购买、家长页面和设置都放在家长验证之后。由于我们不收集任何个人信息，也就不会收集、使用或披露任何儿童的个人信息。

政策变更

如果本政策有变化，我们会更新本页面并修改生效日期。如果将来需要收集任何信息，会事先在 App 中告知并征得家长同意。

Stroke by Stroke Privacy Policy

Effective date: October 26, 2026

Stroke by Stroke: Write Hanzi is an app that helps children practise writing Chinese characters. We do not collect, upload or share any personal information.

We collect no information

• No sign-up or log-in. There are no accounts.
• We do not collect names, ages, email addresses, phone numbers, location, photos, contacts or device identifiers.
• No advertising, no third-party analytics or tracking, and no third-party SDKs.
• The app works offline. The only network activity is purchasing and restoring purchases, which is handled by the Apple App Store.

What stays on the device

To remember where your child is, the app stores the following on the device only. It never leaves the device:

• learning progress, the study log and the review schedule;
• the mistakes list (which characters were written wrong and which strokes);
• handwriting on homework pages;
• in-app settings (daily amounts, voice, speech rate and so on).

Deleting the app deletes all of this. Parents can also delete individual homework pages on the Parents page.

Backup files

On the Parents page, a parent can choose to export a backup file and decide where to save it (for example the Files app or iCloud Drive). The file stays on the parent's own devices and accounts; we never receive it and cannot access it.

Purchases

All purchases, including the 3-day free trial, are made through the Apple App Store. We do not receive any payment details or Apple Account information.

Speech

Characters and voice prompts are read by the speech synthesis built into iOS, on the device. The app does not record audio and does not use the microphone or camera.

Children's privacy

This app is designed for children. Purchases, the Parents page and Settings are behind a parental gate. Because we collect no personal information at all, we do not collect, use or disclose any personal information from children.

Changes

If this policy changes, we will update this page and its effective date. If the app ever needs to collect any information, we will say so in the app and ask for a parent's consent first.
