Memoir Lock: Diary

Memoir Lock is a private, local-first diary for personal memories, secure notes, photos, videos, important dates, and optional iCloud backup. There is no public feed, no stranger community, and no developer-operated server holding your personal content.

CAPTURE IMPORTANT MEMORIES
• Save dates, duration, location, mood, ratings, and personal notes
• Add photos and videos to keep memories vivid
• Organize profiles, anniversaries, and custom options
• Use gentle reminders to keep your journal up to date

REVIEW CHANGES OVER TIME
• Review totals, duration, ratings, streaks, and trends over time
• Revisit places, photos, and meaningful moments
• Use clear statistics to organize your personal records

PRIVACY BUILT FOR PERSONAL CONTENT
• Records, profiles, and media are encrypted on device with AES-GCM
• The encryption key is stored in Apple Keychain
• Your 6-digit Private Lock stores only a one-way verifier, never a readable passcode
• Repeated failed attempts progressively increase the wait time
• The app locks in the background and hides its app-switcher preview
• If you forget the passcode, verify with Face ID, Touch ID, or the device passcode, then reset it

YOUR DATA, YOUR DECISION
• Data stays on your device by default; the developer has no server and cannot view it
• Back up to your personal iCloud only when you choose, and restore when needed
• Continue as a guest or use Sign in with Apple
• Delete local data and personal iCloud backups separately

Memoir Lock is intended for users who want to preserve personal memories, organize life records, and keep private content protected. It is a diary tool and does not provide medical diagnosis or professional treatment advice.
