数据收集
LessKB 及其开发者不会收集、传输、出售或共享个人数据。App 不包含广告、分析、跨 App 跟踪或开发者运营的账号系统。
图片处理与本地存储
图片完全在设备本地处理，不会上传到 LessKB 或开发者运营的服务器。
在正常使用压缩记录功能时，LessKB 会在 App 的私有本地存储中保留最近最多 20 组原图、压缩结果、缩略图、文件大小统计和压缩设置。这些数据不会离开设备，用户可以在“压缩记录”页面将其清空。删除 App 也会删除其本地数据，但设备备份行为由操作系统管理。
只有用户主动选择“保存”时，压缩结果才会写入照片图库；只有用户主动使用系统分享功能时，图片才会提供给用户选择的其他 App。批量压缩结果不会写入单张压缩记录。
购买
LessKB 使用 Apple StoreKit 提供非消耗型终身购买。交易由 Apple 按照其隐私政策处理。LessKB 只使用经过 App Store 验证的交易信息判断是否解锁 Pro，不会将购买信息发送给开发者。
权限
单张模式通过 Apple 系统选择器选择图片，并可能请求向照片图库添加压缩结果的权限。批量模式会请求照片图库读写权限，用于读取用户选择的照片、保存压缩副本，以及在用户主动选择后请求删除对应原图。LessKB 不会自动删除原图；删除操作始终由用户发起，并由 iOS 再次确认。用户可以在 iOS“设置”中管理相关权限。
儿童隐私
LessKB 是通用工具，不会有意收集儿童或成人的个人数据。
政策变更
如果 App 的数据处理方式发生变化，本政策可能更新。本页顶部的生效日期代表最新版本。

Data collection
LessKB and its developer do not collect, transmit, sell, or share personal data. The app contains no advertising, analytics, cross-app tracking, or developer-operated account system.
Image processing and local storage
Images are processed locally and are not uploaded to LessKB or developer-operated servers. LessKB may store up to 20 recent source/result pairs, thumbnails, size statistics, and compression settings in the app's private local storage. Users can clear this history at any time.
Images are added to Photos only when the user explicitly selects Save and are sent to another app only through a user-initiated system share action. Batch results are not added to single-photo compression history.
Photos access and original removal
Single-photo mode uses Apple's system picker and may request add-only access when saving. Batch mode requests read/write access to read selected photos, save compressed copies, and request removal of the matching originals only when the user explicitly chooses that action. LessKB never removes originals automatically, and iOS always asks the user to confirm deletion.
Purchases
Apple StoreKit processes the non-consumable lifetime purchase. LessKB uses verified App Store transaction information only to determine Pro entitlement and does not send purchase information to the developer.
Children's privacy
LessKB is a general-purpose utility and does not knowingly collect personal data from children or adults.
Policy changes
This policy may be updated if the app's data practices change. The effective date at the top of this page identifies the latest version.
