Private writing, by design.
MangoWriter is a secure Windows editor that protects your words from the moment you type them. No stray temp files, no plaintext on disk, and an instant lock screen when you step away.

Why MangoWriter

• Zero plaintext at rest. Content is encrypted before it touches storage.
• Secure clipboard. Copy/paste without leaving readable traces.
• One-click Lock. Masks the screen and requires re-authentication to continue.
• Optional keyfile. Add a second factor that binds documents to your keyfile.
• Fast, familiar editing. A focused editor without security trade-offs.

How it protects your work

• AES-GCM (256-bit). Modern authenticated encryption for confidentiality and integrity.
• Strong key derivation. Passwords are hardened with Argon2 and PBKDF2, then cached in secure memory for the session to keep things snappy.
• Protected operations. Sensitive actions (like export) require re-authentication.
• Local-only by design. No network connectivity, no telemetry, no third-party DLLs. Your files stay with you.
• Clear trust cues. Visual indicators show when a keyfile is loaded and when the session is locked.

Who it’s for

• Professionals handling sensitive drafts and research.
• Legal, finance, and compliance teams that need local-only protection.
• Individuals who want an offline, vault-style way to protect sensitive notes (e.g., recovery codes, API keys, private docs).
• Writers who want privacy without complexity.
• Anyone who prefers a tool over a “platform.”

What makes it different

Typical editors autosave to disk in plaintext, leave temp files behind, or sync to the cloud by default. MangoWriter is built the other way around: encryption is the default, and convenience features are designed to be safe (secure clipboard, lock screen, protected exports).

Licensing

MangoWriter uses a straightforward perpetual license: a Pro license for individuals and an Enterprise option for teams that need unlimited seats and keyfile workflows. See Buy/Licensing for details.

Privacy & Ownership

Your words are yours. MangoWriter doesn’t phone home, doesn’t require an account, and doesn’t make outbound connections. Documents are standard files you control, protected by your password (and optional keyfile).
