About MangoWriter
MangoWriter is a secure text editor for Windows designed to run completely offline with no cloud, AI, network connections, or telemetry, offering a familiar, simple editing experience while keeping content private by default. It uses state-of-the-art AES-256-GCM encryption with strong key derivation (Argon2id) and optional keyfile two-factor support, ensuring no plaintext is ever written to disk and eliminating caches or temp files. MangoWriter protects your work with a secure clipboard that binds copied content to the current session, an instant lock screen to mask content when stepping away, and one-click bulk redaction tools to permanently black out selected text across documents. Sensitive buffers are zeroed after use and your password never gets stored on disk, with key material kept only in secure memory while a document is unlocked. It is delivered as clean, code-signed builds available as an MSI installer or portable ZIP and includes secure export options.
