How Deck Clipboard Protects Your Data
Deck is built with a defense-in-depth approach to clipboard security: your history stays on your Mac by default, with optional layers like biometrics, encryption, and screen-share awareness.
Security pillars
Local-first storage
Clipboard history is stored in a local SQLite database on your Mac — not uploaded to Deck servers by default.
Touch ID protection
Lock sensitive clips behind biometric authentication so they are harder to access if someone else uses your Mac.
AES-GCM encryption
Protected entries use modern authenticated encryption; encryption keys are stored in the macOS Keychain.
Screen-share protection
Deck can hide its window during screen recording and sharing so your clipboard UI does not appear on stream.
What Deck does not do
- No clipboard upload to servers by default
- No ad or third-party tracker SDKs
- No server storage of your AI API keys
- No account or sign-up required
- No selling or monetizing clipboard data
Sensitive content handling
- Detects sensitive patterns (e.g. cards, passwords)
- Per-app exclusion — skip capture entirely
- Password-manager clipboard type awareness
- Smart Rules for automatic filtering
