§ 1 Some things should never enter history
The cleanest way to protect sensitive copies is to never record them. Passwords, MFA codes, API tokens, and the contents of a privileged-document app shouldn't sit in clipboard history at all. A good manager lets you exclude specific apps so anything you copy while they're frontmost is ignored.
§ 2 Which apps to exclude
A practical exclude list for professional work:
- Your password manager (1Password, Bitwarden, etc.) — non-negotiable.
- Any secrets or vault app, and authenticator apps.
- Apps holding especially sensitive client material, where policy requires it.
Exclusion is prevention. What never enters history can never leak from it.
§ 3 How it works in Maccy
Maccy keeps an ignore list you add apps to, and it also honours the system's concealed clipboard flag — the marker apps set on sensitive copies — so well-behaved password managers are skipped even before you configure anything. Combined with local-only storage, that gives you two layers: sensitive copies aren't recorded, and what is recorded never leaves the Mac.
Verify it yourself: copy from your password manager and confirm the entry doesn't appear in history. Trust, then check. Maccy\’s FAQ covers the exclusion behaviour.
§ 4 Frequently asked questions
How do I stop my password manager from being saved in clipboard history?
Add it to your clipboard manager's exclude/ignore list, and use a manager that honours the system 'concealed' flag. In Maccy, both apply — excluded apps and concealed copies are skipped.
What apps should I exclude from clipboard history?
At minimum your password manager and any authenticator or secrets app. Add any application holding especially sensitive material if your policy requires it.
Does Maccy skip passwords automatically?
It honours the system concealed-copy flag that well-behaved password managers set, so those copies are skipped. Adding the app to the ignore list makes it certain.
