LocnLock is a local-first, offline Windows vault for passwords, accounts, secure notes, files, and per-project .env developer config — encrypted on your machine with AES-256-GCM. No account, no cloud, no telemetry, no subscription (one-time purchase). A Recovery Key resets a forgotten master password with no vendor backdoor, and there's a published, honest threat model that says exactly what it does — and doesn't — protect against, instead of an "unhackable" badge.
