LightBox — Support
Turn your iPhone into a professional fill light
💡 LightBox works 100% offline. Most issues can be resolved by following the steps below — no internet connection needed.
Getting Started
LightBox offers two lighting modes:
- Screen Light — Your entire display becomes a soft, adjustable light source. Choose from 10 color tones and fine-tune brightness, temperature, and saturation.
- Flashlight — Precisely control the rear LED brightness from a dim glow to full power.
You can also pick from 16 one-tap scenes (Selfie, Live Stream, Night Reading, Meditation, etc.) — each pre-tuned for the perfect light.
Frequently Asked Questions
Q: Why does the app ask for camera permission?
LightBox uses the camera permission solely to control the rear LED flashlight brightness. It does not capture photos or record video. You can deny this permission and still use Screen Light mode normally.
Q: My screen dims while using Screen Light mode. How do I fix it?
Go to the Settings tab inside LightBox and enable "Screen Always On". This prevents your iPhone from auto-dimming while the light is active.
Q: Can I set the light to turn off automatically?
Yes. LightBox has a built-in Auto-Off Timer with options for 5, 15, or 30 minutes. You'll find it in the app's settings.
Q: Does LightBox collect any data or require an internet connection?
LightBox itself does not connect to the internet or collect any personal data. The only network activity occurs when you purchase or restore LightBox Pro — this is handled entirely by Apple's StoreKit and is subject to Apple's Privacy Policy. No purchase data is sent to our servers.
Q: What is LightBox Pro?
LightBox Pro is a one-time in-app purchase that unlocks all premium features: all 10 color tones, all 16 scenes, color temperature and saturation fine-tuning, auto-off timer, and haptic feedback. It's a lifetime purchase — you pay once and keep access forever.
Q: How do I purchase LightBox Pro?
Tap the golden PRO badge in the top-right corner of the main screen, or tap any locked feature (marked with a lock icon). This will open the Pro upgrade page where you can complete your purchase through the App Store.
Q: How do I restore my purchase?
If you've previously purchased LightBox Pro and need to restore it (for example, after reinstalling the app or switching devices), open the Pro upgrade page and tap "Restore Purchase" at the bottom. Make sure you're signed in with the same Apple ID you used for the original purchase.
Q: I purchased Pro but features are still locked. What should I do?
Try the following steps: (1) Close and reopen the app. (2) Open the Pro upgrade page and tap "Restore Purchase". (3) Make sure you're signed in with the correct Apple ID. (4) Check your internet connection — purchase verification requires a brief connection to Apple's servers. If the issue persists, contact us at support@boundlessstream.com.
Q: What languages does LightBox support?
LightBox supports 8 languages: English, Chinese (Simplified), Japanese, Korean, French, German, Spanish, and Portuguese.
Q: How do I reset all settings to default?
Delete and reinstall the app. Since all settings are stored locally via iOS UserDefaults, reinstalling will restore everything to factory defaults.
Troubleshooting

- Make sure you've granted camera permission: Settings → LightBox → Camera

LightBox — 技术支持
把你的 iPhone 变成专业补光灯
💡 LightBox 完全离线运行。大部分问题可通过以下步骤自行解决，无需联网。
快速上手
LightBox 提供两种灯光模式：
- 屏幕补光 — 整个屏幕变为柔和、均匀的光源。支持 10 种色调，可精细调节亮度、色温和饱和度。
- 闪光灯 — 精确控制后置 LED 亮度，从微弱到最强。
还有 16 个一键场景（自拍、直播、夜读、冥想等）——每个场景都经过专业调色，开箱即用。
常见问题
Q: 为什么需要相机权限？
LightBox 仅通过相机权限控制后置 LED 闪光灯亮度，不会拍照或录像。即使拒绝该权限，屏幕补光模式仍可正常使用。
Q: 使用屏幕补光时屏幕会自动变暗？
进入 LightBox 设置页面，开启「屏幕常亮」即可防止使用时自动变暗。
Q: 可以设置自动关灯吗？
可以。LightBox 内置自动关灯定时器，支持 5、15、30 分钟，在设置中即可开启。
Q: LightBox 会收集数据吗？需要联网吗？
LightBox 本身不联网、不收集任何个人数据。唯一的网络活动发生在购买或恢复 LightBox Pro 时——此过程完全由 Apple StoreKit 处理，受 Apple 隐私政策约束。我们不会向任何服务器发送购买数据。
Q: 什么是 LightBox Pro？
LightBox Pro 是一次性内购，解锁全部高级功能：10 种色调、16 个场景、色温和饱和度微调、自动关灯定时器、触觉反馈。一次购买，永久使用。
Q: 如何购买 LightBox Pro？
点击主界面右上角的金色 PRO 徽章，或点击任何带锁头图标的功能，即可打开 Pro 升级页面，通过 App Store 完成购买。
Q: 如何恢复购买？
如果你之前已购买 LightBox Pro，需要恢复（例如重装应用或更换设备后），请打开 Pro 升级页面，点击底部的「恢复购买」。请确保使用与原始购买相同的 Apple ID 登录。
Q: 购买了 Pro 但功能仍然锁定怎么办？
请尝试以下步骤：(1) 关闭并重新打开应用。(2) 打开 Pro 升级页面，点击「恢复购买」。(3) 确认使用了正确的 Apple ID。(4) 检查网络连接——购买验证需要短暂连接 Apple 服务器。如问题持续存在，请联系 support@boundlessstream.com。
Q: 支持哪些语言？
支持 8 种语言：中文（简体）、英文、日文、韩文、法文、德文、西班牙文、葡萄牙文。
Q: 如何重置所有设置？
删除并重新安装应用即可。所有设置均存储在 iOS UserDefaults 中，重装后会恢复出厂默认值。
