光律使用后置摄像头分析灯具亮度变化。画面只在本机处理，不保存为照片或视频，不上传。App 不使用麦克风或照片库。你可以在系统设置中撤销相机权限。
主动保存的房间、灯具、亮度档位、测量时间、设备类型、参数、波形和分析结果保存在设备上。可在灯具记录页左滑删除，卸载 App 会移除本机 App 数据。系统备份可能包含这些数据，备份保留及恢复由你的 Apple 设置与 Apple 政策决定。
只有你主动分享报告或导出 CSV 时，数据才会交给你选择的 App 或接收方。导出文件可能暂存在 App 缓存中。已分享或另存的副本需在对应位置删除；请在分享前检查房间与灯具名称。
光律不设账号，不含广告、跟踪或第三方分析 SDK，不向开发者服务器发送测量或使用数据。Apple 系统诊断由你的系统设置和 Apple 政策管理。
你主动发送支持邮件时，开发者仅使用邮件中提供的信息回复与排查问题；可通过邮箱申请删除支持通信。请勿发送敏感画面或不必要的个人资料。本网站托管于 GitHub Pages，托管方可能依据其政策处理 IP 地址与访问日志；App 不会向本站发送使用分析数据。

LumaCadence processes rear-camera brightness samples on your device. Frames are not saved as photos or video and are not uploaded. The app does not access your microphone or photo library. You can revoke camera permission in Settings.
Records you choose to save contain room, lamp, brightness setting, time, device type, capture parameters, waveform and analysis results. They stay on your device. Swipe left on a lamp record to delete it. Uninstalling removes local app data. System backups may include app data; backup retention and restoration depend on your Apple settings and Apple's policies.
Only your explicit report-sharing or CSV-export action transfers content to the app or recipient you select. Export files may temporarily remain in the app cache. Delete shared or separately saved copies at their destination. Review room and lamp names before sharing.
The app has no accounts, ads, tracking or third-party analytics SDKs, and sends no measurement or usage data to developer servers. Apple system diagnostics are governed by your settings and Apple's policies.
If you email support, the developer uses the information you provide to reply and troubleshoot. You may request deletion of support correspondence. Do not send sensitive images or unnecessary personal information. GitHub Pages hosts this site and may process IP addresses and access logs under its policies. The app sends no analytics to this site.
