我们收集什么What we collect

不收集任何能识别你身份的信息。舞接龙没有账号系统：我们不知道你的姓名、电话、邮箱或位置，也看不到你的视频、照片和音乐。

Nothing that identifies you. DanceChain has no accounts. We don't know your name, phone number, email or location, and we never see your videos, photos or music.

你的视频、照片和音乐Your videos, photos and music

• 你选的视频和音乐只在手机上使用：对齐音乐、识别动作和人数、接成成片。
• 你选的背景照片只用来合成成片。
• 做好的成片保存在 App 里。只有你点「保存到相册」或「分享」时，它才会离开 App，发到哪里由你决定。
• 相册权限：App 只申请「添加到相册」，用来保存成片，看不到相册里的其他内容。选视频用的是系统自带的选择器，只有你选中的视频才会交给 App。

• Videos and music you pick are used only on your phone: to line up the music, recognise moves and dancers, and make the film.
• Background photos you pick are used only to compose the film.
• Finished films are kept inside the app. They leave it only when you tap Save to Photos or Share, and you choose where they go.
• Photos access: the app only asks to add to your library, to save films. It can't see anything else there. Videos are chosen with the system picker, so the app receives only the videos you pick.

AI 和 AI 背景AI and AI backgrounds

识别动作、数人数、抠出跳舞的人，都用 Apple 系统自带的功能在手机上完成。「AI 生成背景」使用 Apple 的 Image Playground，同样在你的设备上生成，受 Apple 隐私条款保护。

Recognising moves, counting dancers and cutting them out all happen on the phone with Apple's built-in frameworks. “Generate with AI” backgrounds use Apple's Image Playground, which also runs on your device under Apple's privacy terms.

免费次数Free saves

为了让每台设备的免费保存次数公平，App 会通过 Apple 的设备验证服务确认这台设备已经用了几次免费保存。这个检查只用到一个匿名的设备凭证，由我们的服务器转交给 Apple、不做保存。它不包含你的任何信息，也不包含你的视频。

To keep free saves fair for every device, the app checks with Apple's device verification service how many free saves this device has used. The check uses only an anonymous device token, which our server passes to Apple without keeping it. It contains nothing about you and nothing from your videos.

购买和订阅Purchases and subscriptions

订阅和购买都由 Apple 的 App Store 处理。我们收不到你的付款信息或 Apple 账户信息，App 只知道这台设备有没有开通 Pro。

Subscriptions and purchases are handled by Apple's App Store. We never receive your payment details or Apple Account information; the app only learns whether Pro is active.

问题日志Problem logs

为了方便排查问题，App 会在手机上记一份处理日志（步骤、用时、视频的文件名和时长，不含视频内容）。只有你在「设置 › 发送日志」里主动发给我们时，它才会离开手机。

To help fix problems, the app keeps a processing log on your phone (steps, timings, video file names and lengths, never video content). It leaves your phone only if you send it to us from Settings › Send Log.

如果你在 iPhone 设置里选择了「与 App 开发者共享」，Apple 可能会把匿名的崩溃报告转给我们，帮助我们修复问题。

If you've chosen to share analytics with app developers in your iPhone's settings, Apple may pass anonymous crash reports on to us so we can fix bugs.

儿童Children

舞接龙不专门面向 13 岁以下的儿童，也不收集任何人的个人信息。

DanceChain isn't directed at children under 13 and doesn't collect personal information from anyone.

你的选择Your choices

内容都在你的手机上，由你掌握：随时可以在 App 里删掉成片；删除 App 会清除它保存的成片和设置（免费次数的计数除外）。保存到相册或分享出去的视频，由你自己管理。

Everything is on your phone and under your control. Delete films in the app at any time; deleting the app removes its films and settings (except the free-save count). Videos you saved to Photos or shared are yours to manage.
