生效日期：2026 年 10 月 2 日
JofolL 将导入的文件、封面、阅读进度、分组、书签、标注、手写笔迹与设置保存在设备内的 App 存储空间。App 不要求注册账户，没有广告、分析或追踪 SDK，也不会将这些阅读数据上传给开发者。
你选择从 iCloud Drive 或其他文件服务导入时，相关服务由 Apple 或该服务提供商负责。普通书库可能包含在你启用的系统设备备份中。隐私书库使用 iOS 文件保护，并设置为不纳入 App 自动备份。JofolL 不提供跨设备书库或阅读进度自动同步。
隐私书库通过系统的 Face ID、Touch ID 或设备密码验证。JofolL 不接收或保存你的生物特征或设备密码。进入后台会锁定隐私书库，并遮挡其 App 切换器预览；这不阻止用户截图或其他设备拍摄。
当你主动发送支持邮件，开发者会收到你提供的邮箱地址、正文及附件，并仅用于处理该请求。请勿发送密码、私人书籍或其他敏感材料。你可以通过支持邮箱请求删除相关支持邮件。
移除书籍后，可以在相应书库的“最近删除”中恢复。永久删除后无法通过 App 恢复。卸载 App 会移除设备上的 App 本地数据，系统备份的管理由设备备份设置负责；你的导入前原文件不受 App 的书库移除操作影响。
Effective October 2, 2026. JofolL keeps imported books, images, covers, progress, folders, bookmarks, annotations, handwriting and preferences in the app’s local storage. It does not require an account, include advertising or analytics/tracking SDKs, or upload reading data to the developer.
Cloud file providers you choose operate under their own policies. The normal library may be included in your enabled device backups. The private library uses iOS file protection and is excluded from automatic app backup. There is no automatic cross-device library or progress synchronization.
Private-library authentication is handled by Face ID, Touch ID or the device passcode. JofolL never receives biometric data or the passcode. Backgrounding locks the private library and obscures its app-switcher preview; it does not prevent screenshots or external photographs.
Support emails contain only what you choose to send, including your email address and attachments. They are used to handle your request; contact the support address above to request deletion. Avoid sending sensitive or unauthorized material. Library removal supports Recently Deleted; permanent deletion cannot be undone in the app. Uninstalling removes local app data. Your original imported source files are not removed by library actions.
