隐私政策
背背词 · 生效日期：2026 年 11 月 6 日
一句话：背背词不收集、不上传你的任何信息。你录入的内容只存在你自己的设备上。没有账号，没有服务器，也没有广告和统计工具。
我们收集哪些信息
不收集。背背词不会把任何数据发给我们或第三方。除了购买永久会员时通过 Apple 的 App Store 付款和验证，应用不联网。应用里也没有接入任何第三方 SDK，包括广告、统计分析和崩溃上报。
存在你设备上的内容
为了让应用能用，下面这些内容会保存在应用自己的存储空间里，只在你的设备上：
- 你录入的原文、标注的 Target 和你写的描述 / 释义；
- 你给情景选的配图（压缩后复制一份存进应用）；
- 复习记录（哪几天复习过）、每个情景的出现频率，以及首页场景等设置。
你可以随时在应用里删除某个情景，它的原文、配图和标注会一起删掉。删除应用，上面这些内容会全部清除。
背背词自己不使用 iCloud，不会把任何内容同步或上传到 iCloud。如果你开启了 iPhone 的整机备份（设置里的「iCloud 云备份」，或者连电脑备份），iOS 会按你的设置把整台设备的数据一并备份，其中也包括背背词的数据。这是系统功能，由 Apple 处理，适用 Apple 的隐私政策，我们接触不到。
照片
添加配图时，使用的是 iOS 系统的照片选择器。应用只能拿到你选中的那一张，看不到你相册里的其他照片，所以不需要申请相册权限。
朗读
朗读功能使用 iOS 系统自带的语音合成，在你的设备上完成，文字不会发给我们。
剪贴板
只有在你点「复制提示词」时，应用才会往剪贴板里写一段提示词。应用不会主动读取你的剪贴板，往输入框里粘贴的内容都是你自己操作的。
购买
永久会员通过 Apple 的 App 内购买完成，付款由 Apple 处理。我们拿不到你的付款信息、Apple ID 或其他个人信息。应用只会向 App Store 确认这台设备是否已经购买，用来开通会员功能。
儿童隐私
背背词不收集任何人的个人信息，也包括儿童。
政策变更
如果这份政策有更新，我们会修改本页并更新上面的生效日期。如果将来应用开始收集任何信息，会先更新本政策并在应用里告知你。

Privacy Policy
背背词 · Effective November 6, 2026
In short: 背背词 does not collect or upload any of your information. Everything you enter stays on your own device. There are no accounts, no servers, and no ads or analytics.
Information We Collect
None. 背背词 never sends any data to us or to third parties. Apart from paying for and verifying the Lifetime Membership through Apple's App Store, the app does not connect to the internet. The app contains no third-party SDKs, including advertising, analytics, or crash reporting.
Content Stored on Your Device
For the app to work, the following is saved in the app's own storage, on your device only:
- the passages you enter, the targets you mark, and the descriptions or definitions you write;
- the images you attach to situations (a compressed copy is saved in the app);
- your review history (which days you reviewed), how often each situation appears, and settings such as the home scene.
You can delete any situation in the app at any time; its passage, image, and marks are deleted with it. Deleting the app removes all of the above.
背背词 itself does not use iCloud and never syncs or uploads anything to iCloud. If you have iPhone's whole-device backup turned on (iCloud Backup in Settings, or a computer backup), iOS backs up the data on your device according to your settings, including 背背词's data. This is a system feature handled by Apple under Apple's privacy policy, and we have no access to it.
Photos
Images are added through the iOS system photo picker. The app only receives the photo you choose and cannot see the rest of your library, so it does not request photo library access.
Read Aloud
Read aloud uses the speech synthesis built into iOS. It runs on your device, and the text is never sent to us.
Clipboard
The app writes to the clipboard only when you tap “复制提示词” (Copy prompt). It never reads your clipboard on its own; anything pasted into a text field is pasted by you.
Purchases
The Lifetime Membership is bought through Apple's In-App Purchase, and payment is handled by Apple. We never receive your payment details, Apple ID, or any other personal information. The app only asks the App Store whether this device has made the purchase, in order to unlock membership features.
Children's Privacy
背背词 does not collect personal information from anyone, including children.
Changes to This Policy
If this policy changes, we will update this page and the effective date above. If the app ever begins collecting any information, we will update this policy and let you know in the app first.
