LexLoop Privacy Policy

What We Collect
LexLoop has no account system and asks for no personal information. On first launch the app requests an anonymous user ID from our server — a randomly generated identifier containing no name, email, or other identity information — used to authenticate API calls and for rate limiting.
How Data Is Used
- Learning progress (word books, plans, recall grades, marked words) is stored only on your device and is never uploaded.
- Article checks send the word list you select to our backend, where a large language model generates a short article. Only the words themselves are sent — no personal information is included.
- The anonymous ID exists solely to authorize and rate-limit generation requests.
Third-Party Services
Article generation relies on our own backend service (kaobuddy-api-test.lzwmax.online), which forwards requests to a large-language-model provider. Beyond that, LexLoop integrates no advertising, analytics, or tracking SDKs and connects to no third-party data services.
Data Deletion
Deleting the app removes all learning data on the device. The anonymous ID is linked to no personal identity, so no separate account deletion is needed.

我们收集什么
LexLoop 不注册账号、不要求任何个人信息。首次启动时 App 会向服务器请求一个匿名用户标识（随机生成，不含姓名、邮箱或任何身份信息），用于调用接口时的鉴权与限流。
数据怎么用
- 学习进度（词书、计划、单词掌握情况、生词标记）全部保存在你的设备本地，不会上传。
- 文章检验功能会把你选择的目标单词列表发送给我们的后端服务，由大语言模型生成短文。发送的内容只有单词本身，不含任何个人身份信息。
- 匿名标识仅用于调用生成接口的鉴权与限流。
第三方服务
文章生成依赖我们自己的后端服务（kaobuddy-api-test.lzwmax.online）转发至大语言模型提供商。除此之外 LexLoop 不集成任何广告、统计或追踪 SDK，不接入第三方数据分析服务。
数据删除
删除 App 即删除设备上全部学习数据。匿名标识不关联任何个人身份信息，无须单独注销。
