感谢使用 行灯（Andon）。行灯是一款在您的手机上点亮闪光灯、提供常亮与多种节奏照明的和风手电筒应用。
我们深知照明灯具总被放置在离生活最近的地方，因此我们对待您的隐私也如同对待灯火的温度——简单、克制、不过度。本政策向您说明本应用如何处理您的信息。使用本应用即表示您已阅读并同意本政策。
一、我们收集的信息
我们不收集任何个人信息。

- 本应用不采集位置、通讯录、照片、通话记录、设备标识符或使用行为数据。
- 本应用不包含广告、统计分析或第三方追踪代码。
- 应用内所有功能均在本机运行，点亮闪光灯不会触发任何拍摄、录音或数据传输。
二、权限使用说明
本应用仅在实现核心功能所必需时申请以下权限，且不会用于声明之外的目的：
| 相机 | CAMERA用于调用系统手电筒接口点亮设备闪光灯，或进行屏幕补光。应用不预览、不拍摄、不录像，也看不到任何画面。 |
|---|---|
| 保持唤醒 | WAKE_LOCK当您选择「行灯」模式在离开应用后继续保持点亮时，用于维持闪光灯稳定工作；仅在灯火点亮期间申请，熄灭后立即释放。 |

- 若您开启了系统「备份与恢复」，系统可能将上述偏好备份至您的 Google 云端硬盘（由操作系统管理，本应用无法读取或控制）。您可在系统设置中随时关闭备份，或通过「卸载应用」删除全部本地数据。

Thank you for using Andon — a washi-paper themed torch that lights your device’s flash for steady or rhythmic illumination.
Just as a lamp is kept simple and warm, we treat your privacy the same way: minimal, honest, and never more than necessary. This policy explains how the app handles your information. By using the app you agree to this policy.
1. Information We Collect
We do not collect any personal information.
- The app requires no account, no login, and no phone number, email, or social profile.
- The app does not gather location, contacts, photos, call history, device identifiers, or usage behavior.
- The app contains no advertising, analytics, or third-party tracking code.
- Everything runs locally on your device. Turning on the flash never triggers recording or data transfer.
2. Permissions We Use
Permissions are requested only when necessary for core features, and are never used for anything else:
| Camera | CAMERAUsed to control the system torch so the flash can be lit, or to provide screen light. The app never previews, captures, or records any image. |
|---|---|
| Wake lock | WAKE_LOCKKeeps the processor awake so the lamp stays steadily lit when you choose the “Andon” keep-on behavior. It is held only while the light is on and released immediately after. |
| Vibration | VIBRATEProvides gentle haptic feedback (can be turned off anytime in Settings). |
You can review or revoke these permissions at any time under System Settings → Apps → Andon → Permissions. Revoking them disables the lighting features but affects nothing else on your device.
3. Local Data & System Backup
- Your preferences (default brightness, sound, haptics, keep-on behavior) and this consent record are stored on your device only as ordinary preference files. Nothing is uploaded.
- If you enable system “Back up and restore”, the OS may include these preferences in your Google Drive backup (managed by the operating system; the app cannot read or control it). You can disable backup anytime, or uninstall the app to erase all local data.
4. Network & Third Parties
The app has no network permission and never connects on its own. This privacy page is statically hosted on Firebase Hosting (Google) for reading in your browser; the app itself loads no remote content.
5. Children’s Privacy
The app collects no personal information and is safe for users of all ages, including children. We do not knowingly collect personal data from children.
6. Changes to This Policy
If this policy changes, we will update the date at the top of this page and publish the latest version. For significant changes, the app will ask for your consent again on the next launch.
7. Contact Us
If you have any questions or suggestions about this policy or how the app handles data, please reach us at:
