LuWu is a local-first file manager and encryption tool for iOS. Browse, filter, and preview everyday files, package sensitive items as LWEF encrypted files, or move them into a PIN-protected Vault. Key features: - File management: filter images, videos, PDFs, ZIP archives, LWEF packages, and more. - LWEF encryption: package selected files into standalone encrypted files with a file password, optional cover, and optional local master-password unlock. - Private Vault: protect important files with a 6-digit PIN. Vault contents stay hidden while closed. - Wi-Fi transfer: upload files from a computer browser to your iPhone on the same local network, without a cable. - Master password and iCloud backup: generate a strong master password and optionally back it up to iCloud for recovery. - Files app integration: import, open, and manage local documents through the iOS file system. LuWu has no account system and no ad tracking. File handling is centered on your device; iCloud is used only when you enable master password backup. Supported languages: English and Simplified Chinese.
