EXT4 Access — Privacy / 隐私政策
EXT4 Access Privacy / 隐私政策
Updated / 更新：2026-10-22
App processing
EXT4 Access processes connected-drive information, file contents and filesystem metadata locally to provide filesystem access and guard disk operations. The host reads device capacity, partition identity, filesystem and mount status; the extension processes the files and metadata requested by macOS clients. The app does not require a user account.
The scoped inspection of the current shipping implementation identified no developer-operated analytics, account/login service or automatic file-upload path. Its configured app/extension entitlements request no network client/server capability. These observations describe the inspected implementation; they do not assert that every macOS service is offline or replace the App Store's separate privacy disclosures.
Diagnostics and Apple services
macOS-managed diagnostics may retain operation errors and device/filesystem identifiers. Ordinary lifecycle/error logging and development performance recording are distinct. We do not claim that diagnostics contain no identifiers, promise immediate removal of system logs, or control Apple's separate Store, account and operating-system processing. Other applications accessing your mounted files have their own data practices.
Voluntary support messages
Support correspondence is used only to handle your support or privacy request. We do not add you to a mailing list or forward your message to other recipients.
If you email norvynzhang@gmail.com, the message and any attachments you choose to send are handled through that Gmail mailbox and Google's email infrastructure to respond to your support or privacy request. Sending a message is separate from the app's local filesystem processing. Do not send passwords, an entire drive image or unnecessary personal files. Review and remove sensitive contents and identifiers before attaching diagnostics.
No fixed retention period has been established for voluntary support correspondence. Contact the same address to ask about a message or request deletion. This policy does not promise a deletion deadline or removal of independently retained provider/system backups. No automatic diagnostic upload or fixed-response-time support service is promised.

中文隐私说明
EXT4 Access 为提供文件系统访问并保护磁盘操作，在本机处理连接磁盘的信息、文件内容和文件系统元数据。主应用读取容量、分区身份、文件系统及挂载状态；扩展处理 macOS 客户端请求的文件与元数据。应用不需要用户账号。
对当前交付实现的范围内检查未发现开发者运营的分析、账号登录或自动文件上传路径，当前权限配置未申请网络客户端或服务器能力。这描述的是已检查实现，不表示 macOS 的全部服务都离线，也不代替 App Store 的单独隐私披露。
macOS 管理的诊断可能保留操作错误、设备与文件系统标识。日常错误/生命周期日志与开发性能记录不同；我们不声称诊断不含标识，不承诺系统日志立即删除，也不控制 Apple 商店、账号及操作系统的独立处理。访问已挂载文件的其他应用有各自的数据处理方式。
支持邮件仅用于处理您的支持或隐私请求，不用于邮件列表，也不会转发给其他收件人。
如果您主动发邮件至 norvynzhang@gmail.com，邮件及自愿附带的附件会通过该 Gmail 邮箱和 Google 邮件基础设施处理，用于回复支持或隐私请求。主动发信不同于应用本地文件处理。请勿发送密码、整个磁盘镜像或不必要的个人文件，附加日志前请检查并移除敏感内容与标识。
目前未为自愿支持邮件设立固定保留期限。可通过同一邮箱咨询相关邮件或提出删除请求；本政策不承诺删除时限或清除服务商/系统独立保留的备份，不承诺自动诊断上传或固定响应时间。
