Is a clipboard manager safe on Mac?

A clipboard manager is as safe as where it keeps your history. Look for one that stores clips only on your Mac, encrypts them at rest, and skips passwords. Copycat does all three: no network access, AES-GCM 256-bit encryption with the key in your Keychain, and password-manager copies skipped by default.
What does a clipboard manager store?
Everything it records from your clipboard, so it matters what it keeps and where.
Copycat records text only, and keeps your last 1,000 clips.
What should I check before installing one?
Check these before you install any clipboard manager:
- Where history is stored: on your Mac, or synced to a server or iCloud.
- Whether history is encrypted at rest.
- Whether it skips password-manager and concealed copies.
- Which permissions it asks for.
- How it is paid for: a one-time price or a subscription.
Does a clipboard manager need Accessibility permission?
Not always. Copycat asks for no permissions: it copies the clip you pick, and you press ⌘V.
Will a clipboard manager record my passwords?
It depends on the app. With Skip sensitive content on (the default), Copycat skips copies from password managers and anything an app marks as concealed, so they're never written to history.
Does Copycat sync my clipboard to iCloud?
No. Copycat runs in the App Sandbox with no network access, so it can't sync or phone home. There's no account and no analytics in the app.
How is Copycat's history encrypted?
With AES-GCM 256-bit encryption at rest. The key is stored in your macOS Keychain.
