concealer collects no personal data. There is no account, no analytics, no advertising, no tracking, and no company servers. The app is designed to keep your secrets on your own devices.
Your vault (secrets you add) is stored only on your device, encrypted with your master password. Decrypted values exist only in memory while the vault is unlocked. We never receive, see, or store your secrets or your master password.
The app makes network requests only to a concealer host that you run on your own local network (your computer), and only to sync your vault. Secret values are end-to-end encrypted with your master password and are never sent in plaintext. The app does not contact any server operated by us or any third party.
None. No data is shared with anyone, because none is collected.
concealer is a developer tool and is not directed at children.
