Some notes are too personal for a regular notes app. Safety Note+ gives you a dedicated private space for personal writing, sensitive lists and ideas you want to keep separate. Unlock quickly with Face ID, Touch ID or a passcode, organize notes in folders, and choose optional sync or backup when you need it. PRIVATE ACCESS • Protect the app with a passcode or supported biometric unlock • Choose PIN, password or pattern-style access where available • Return to your notes quickly without mixing them with everyday notes DECOY AND INTRUDER FEATURES • Set a decoy password that opens alternate content • Review supported intruder reports after failed unlock attempts • Enable only the privacy features that fit your needs FOLDER-LEVEL PROTECTION • Add separate protection to selected folders • Keep personal, journal, work and other private notes organized • Use folder colors and icons to find important content faster WRITE AND ORGANIZE • Create short notes, long-form writing and private lists • Search, sort, move and copy notes • Auto-save helps preserve changes as you write • Choose from available themes SYNC, BACKUP AND DEVICE CHANGES • Keep notes on your device for a local-first workflow • Enable iCloud Sync on supported Apple devices • Use optional Cloud Backup when available • Check your backup before changing devices or deleting the app PRIVACY YOU CAN UNDERSTAND Face ID and Touch ID are handled by Apple. Safety Note+ does not receive or store your biometric face or fingerprint data. Sync and backup are optional and depend on the services you enable. Safety Note+ is designed for private notes, personal journals, sensitive lists, confidential ideas and information you prefer to keep separate from a regular notes app. Some features require an in-app purchase or subscription. Feature availability may vary by device, operating-system version and region.

Koz
Read full descriptionHide full description
Koz is a privacy-focused notes app built around one idea. What you write belongs only to you. Koz never connects to the internet. No accounts, no servers, no analytics, no ads. Everything in your notebook stays only on your device. SECURITY • Notes are sealed with AES-256-GCM, the whole database is encrypted with SQLCipher. • The PIN that unlocks the app also derives the encryption key (Argon2id); the PIN itself is never stored anywhere. • Unlock quickly with fingerprint or Face ID. • Emergency password: entering it shows "wrong PIN" on screen, but quietly wipes the vault. Built for moments you're forced to unlock the app. NOTES • Organize freely with folders inside folders. • Attach photos, files, and voice memos, all encrypted the same way as your text. • Hide any note or folder so it disappears completely from browsing; only you can bring it back. BACKUP • Create an encrypted backup file any time, protected with its own separate password. • Backups are never uploaded anywhere; where you keep them is entirely up to you.
