MaskedMemo

Write private notes without displaying what you type.

MaskedMemo shows entered text as bullets and encrypts memo bodies on your device. No account or cloud sync is required; your notes remain managed locally on the device.

KEY FEATURES

• Blind input that displays entered text as bullets
• On-device AES-GCM encryption for memo bodies
• Viewing authentication with Face ID, Touch ID, or a 4-digit PIN
• Automatic locking after a selected period of inactivity
• A privacy overlay when switching away from the app
• Automatic locking after screenshot detection and during screen recording
• Quick Mask for immediately hiding visible content
• Trash and immediate-delete modes
• Japanese and English interface languages

FREE VERSION

Save up to 10 notes. Core protection features—including blind input, encrypted storage, viewing authentication, and automatic locking—are available for free.
