Glass Book Reader — Privacy Policy

Effective date: 2026-10-09

Glass Book Reader is an iPhone app that reads your own e-books aloud with the voices built into iOS and, if you own Meta Ray-Ban Display glasses, shows the lines being read on the glasses. This policy explains what the app does with your data.

What stays on your phone

• Your books. The EPUB, PDF and TXT files you import, the text extracted from them, your reading position and your settings are stored only on your device. Glass Book Reader has no accounts and no servers, and it never uploads your books or their text.
• Speech. Text is read by the speech voices installed on your iPhone (Apple's AVSpeechSynthesizer). Glass Book Reader does not use cloud text-to-speech.
• Diagnostics. The app keeps a small local log of technical events (for example connection states and timing numbers) to help you report problems. It never contains book text, titles, file names or device names, and it leaves your phone only if you choose to copy or share it yourself.

What Glass Book Reader does not do

• No analytics, advertising or tracking SDKs.
• No account, sign-in or e-mail collection.
• No access to the camera, microphone, location, contacts, photos or health data.

Meta glasses

Showing text on Meta glasses uses Meta's Device Access Toolkit and requires the Meta AI app, where you approve Glass Book Reader once. That approval, the Bluetooth and Wi-Fi link to the glasses, and any network traffic of Meta's toolkit or of the Meta AI app are governed by Meta's privacy policy, not by this one. Glass Book Reader has turned off the toolkit's optional crash reporting. The lines of text shown on the glasses are sent to the glasses over the local link; Glass Book Reader does not send them anywhere else.

Permissions the app asks for

• Bluetooth and local network: only to connect to your glasses.
• Background audio: so reading continues when the screen is locked.

Children

Glass Book Reader does not knowingly collect any personal information from anyone, including children.

Changes and contact

If this policy changes, the new version will be posted at this address with a new effective date. Questions: domchiu1024@gmail.com.

Glass Book Reader 隐私政策

生效日期：2026-10-09

Glass Book Reader 是一款 iPhone 应用：用 iOS 自带的语音朗读你自己的电子书；如果你有 Meta Ray-Ban Display 眼镜，还会把正在朗读的文字显示在眼镜上。本政策说明应用如何处理你的数据。

只保存在你的手机上

• 你的书。你导入的 EPUB、PDF、TXT 文件、从中提取的文字、阅读进度和设置都只保存在你的设备上。Glass Book Reader 没有账号，也没有服务器，不会上传你的书或书中的文字。
• 朗读。文字由 iPhone 上安装的系统语音（Apple 的 AVSpeechSynthesizer）朗读。Glass Book Reader 不使用云端语音合成。
• 诊断信息。应用会在本地保留一份很小的技术日志（例如连接状态和耗时数字），便于你反馈问题。日志不含书的内容、书名、文件名或设备名称；只有你自己选择复制或分享时，它才会离开你的手机。

Glass Book Reader 不会做的事

• 不含任何统计分析、广告或跟踪 SDK。
• 不收集账号、登录信息或电子邮件。
• 不访问相机、麦克风、位置、通讯录、照片或健康数据。

Meta 眼镜

在 Meta 眼镜上显示文字需要使用 Meta 的 Device Access Toolkit，并需要你在 Meta AI 应用中授权 Glass Book Reader 一次。该授权、手机与眼镜之间的蓝牙和 Wi-Fi 连接，以及 Meta 工具包或 Meta AI 应用自身的网络行为，均受 Meta 的隐私政策约束，而不是本政策。Glass Book Reader 已关闭该工具包可选的崩溃报告功能。显示在眼镜上的文字通过本地连接发送到眼镜，Glass Book Reader 不会把它发送到其他任何地方。

应用申请的权限

• 蓝牙和本地网络：仅用于连接眼镜。
• 后台音频：锁屏后继续朗读。

儿童

Glass Book Reader 不会有意收集任何人（包括儿童）的个人信息。
