Why your clipboard history should never leave your Mac
Think about what you copy in a typical day. Passwords. Two-factor codes. API keys. Bank account numbers. Medical details. Contract terms. The clipboard is one of the most sensitive surfaces on your computer — and most apps ship your history straight to the cloud.
Cloud sync isn't just a setting you can turn off. It's an assumption baked into the solution: your data has to leave your machine to sync your clips. That means servers, accounts, breach surfaces, and terms of service you agreed to without reading.
Copycat is designed differently. Every clip stays on your Mac. There are no servers, no iCloud sync, no network calls. Your clipboard history is encrypted at rest using AES-GCM with keys stored in your macOS Keychain — the same store protecting your sensitive passwords. Password manager entries are automatically skipped. Zero data leaves your machine.
This is not a feature decision or setting. It's the foundation of Copycat.
