About concealer
concealer is a companion toolbar UI for the concealer secret manager — The local-only secret manager for the AI-coding era.
Open your vault and copy secret values from Chrome without ever typing `cer web`.
FEATURES
• One-click copy — click a secret to copy its value; the clipboard auto-clears after a few seconds.
• Per-field copy — multi-field secrets (database host/user/password, OAuth app key/secret/token…) expand into child rows. Copy or reveal exactly the field you need; non-secret fields show inline.
• On-demand — the local vault server starts only when you open the popup and shuts itself down when idle, so nothing lingers in the background.
• Auto-lock — a countdown locks the popup on its own short timer (configurable), independent of the server, and blinks when it's about to expire.
• Password generator — generate strong passwords / hex / base64url / UUID and copy them.
• Themes — Dark, White, and Matrix, matching the concealer web UI.
• Search — filter by name, tag, project, or environment.
PRIVACY
The extension talks ONLY to your own concealer server on 127.0.0.1 (localhost).
No data is collected, and nothing is ever sent to a remote server.
Secret values are never logged.
REQUIREMENTS (one-time)
1. Install concealer: brew install fxerkan/tap/concealer (macOS)
or: scoop install fxerkan/concealer (Windows)
2. Register the native helper: cer chrome-extension
The extension shows this setup step until it's done.
