NotchMindCopied secrets linger on the clipboard, where any app can read them. Secret Guard watches for them and helps you clear them.
What it looks for
Secret Guard checks copied text, on your Mac, for patterns such as:
- GitHub, Stripe, OpenAI and Anthropic keys
- AWS access keys and secret keys
- Private keys (PEM)
- JWTs and bearer tokens
- Labelled credentials, like
password = …orapi_key: … - Long random tokens that look like a key
When it finds one
The notch shows a red Possible secret copied card:
- Clear Clipboard empties the clipboard straight away.
- Keep Once leaves it on the clipboard this time, for when you’re about to paste it.
- Ignore This Pattern stops warning about this kind of secret. NotchMind asks you to confirm, because it turns that check off until you undo it: Clear Clipboard History in Settings → General → Support turns every check back on.
Whatever you choose, a suspected secret is never saved in clipboard history, and with Smart Mode on it’s never sent for classification.
It isn’t a guarantee
Secret Guard checks for known patterns. It can miss something sensitive, or flag something harmless. Treat it as a helpful warning, not a password manager. Copying from a password manager is safest: NotchMind ignores 1Password, Bitwarden, KeePassXC, LastPass, Dashlane, Passwords and Keychain Access entirely.
