VoiceNote — Your Hands-Free Recording Companion

VoiceNote Privacy Mode: Secure, Local Voice Storage

What it is

VoiceNote Privacy Mode stores recordings and transcriptions only on your device — no cloud upload unless you choose to share. It’s designed to keep sensitive voice data private while retaining full app functionality.

Key features

• Local storage: Audio files and transcripts remain on-device by default.
• End-to-end optional sharing: When you opt to share, data is encrypted client-side before sending.
• Automatic expiration: Set recordings to auto-delete after a chosen timeframe (e.g., 7, 30, 90 days).
• On-device transcription: Speech-to-text runs locally using an embedded model to avoid sending audio to servers.
• Locked notes: Protect specific recordings with a passcode, biometric unlock, or system keychain.
• Offline mode: Full recording and playback without network access.
• Export controls: Exported files can be watermarked or encrypted; sharing prompts show exactly what metadata will be included.

Security & privacy design

• Encrypted at rest: Local files use AES-256 encryption tied to device credentials.
• No cloud backups by default: Backups to cloud drives are disabled; enabling them requires explicit user consent and warns about potential exposure.
• Minimal metadata: App minimizes stored metadata (no location or device identifiers unless you enable them).
• Audit logs: Local-only audit logs show access events; they are not transmitted externally.
• Transparent permissions: Clear explanations before requesting microphone, storage, or biometric access.

User controls (recommended defaults)

1. Privacy Mode ON (default): Local-only storage, local transcription, auto-delete 30 days.
2. Share with Encryption: Manual, per-item encrypted share.
3. Cloud Backup OFF: Off by default; enable with explicit confirmation.
4. Biometric Lock: Optional for sensitive notes.

Who it’s for

• Journalists handling confidential sources
• Therapists and clients recording sessions
• Anyone who prefers sensitive voice data kept off servers

Trade-offs to consider

• On-device transcription may be less accurate or slower than cloud models.
• Large local storage can consume device space unless auto-delete or manual cleanup is used.
• Cross-device sync requires opt-in and encrypted transfer setup.
