AI agents and build tools need your API keys. Handing them over usually means
writing them into a dotfile, an environment variable or a config directory —
where they sit forever, readable by anything on the machine, long after the job
is done.
ValetFS is the other way round. Your secrets live on your iPhone, in the
Keychain, behind Face ID. When a tool on your computer needs one, ValetFS lends
it — into memory, never to disk — and takes it back when you are finished.
HOW IT WORKS
• Install the ValetFS daemon on your computer and start it. It prints a QR code.
• Scan the code with the app. The two are now paired.
• Push a secret from your phone. It appears on the computer as an ordinary file
that any tool can read — but it exists only in memory.
• Close the app, and a grace timer starts. When it expires the daemon unmounts
and wipes itself. Nothing is left behind on disk.
END-TO-END ENCRYPTED
Secrets are encrypted on your phone for one specific daemon, using X25519 key
agreement and ChaCha20-Poly1305. The relay that carries them sees only
ciphertext. We cannot read your secrets, and neither can anyone operating the
infrastructure in between.
BUILT FOR AGENTS
Provision a session from the app and hand an AI agent a single connection key.
The agent installs the daemon and joins — and you keep the authority to revoke
it. One tap forgets the session, and a still-running daemon locks itself,
unmounts, and wipes its memory.
NO ACCOUNT, NO TRACKING
There is no sign-up and no login. No analytics SDK, no advertising, no
behavioural tracking. The app is a client for infrastructure you can inspect —
the daemon and the relay are both open source.
REQUIRES A COMPUTER
ValetFS is a companion to the ValetFS daemon, which runs on macOS or Linux and
is a free open-source download. The app on its own has nothing to pair with.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• The session screen now tells you when your secrets will go, not just how long the window is — “if this disconnects now, they are wiped around 10:21 PM on Sep 13”.
• Back up your vault. Every secret and its path, sealed into one encrypted file with a passphrase you choose, and restored the same way.
• Backup passphrases now start at eight characters.
