Terms

Last updated 17 July 2026 · The short version. Manta UI is open source, your box is yours, and we don't warranty anything — but we'll do our best.

These terms cover the desktop app (macOS and Windows), the phone client (native iPhone app), and the operated push gateway at gateway.mantaui.com. They do not cover anything your AI agent does inside your tmux session — that's between you and your model provider.

Your box is yours

Manta UI is software you run on hardware you own. The server runs under your user account on your Linux box; the desktop app runs on your Mac; the phone client runs on your phone. You are responsible for what runs on those machines and what your agents do with that access.

We do not host your code, your sessions, your files, or your transcripts. Everything you produce lives in ~/.manta/ on your box.

The push gateway is our service

Devices connect directly to your box at https://<box_id>.boxes.mantaui.com — Caddy on your box terminates TLS and reverse-proxies to the loopback server. The ONLY thing we still operate is the push gateway at gateway.mantaui.com, which holds the Apple APNs key (which structurally cannot live on your box) and fans out native pushes on your box's behalf. See the Privacy page for what we store there.

Acceptable use

Don't use Manta UI to:

No warranty

Manta UI is provided as is, without warranty of any kind, express or implied, including but not limited to the warranties of merchantability, fitness for a particular purpose, and noninfringement. In no event shall the authors or copyright holders be liable for any claim, damages, or other liability arising from, out of, or in connection with the software or the use or other dealings in the software.

The desktop app is signed and notarized. On macOS, Gatekeeper does not block a standard download — right-click → Open is not required.

No paid tier

Free to use. The desktop app, the native iPhone app, and the push gateway are free to use, and the self-hosted server is open source (MIT). Manta has no paid tier, no per-seat fee, and no in-app purchase. You pay only your model provider for usage on your own box.

Changes to the service

We may change, suspend, or discontinue the push gateway with reasonable notice (a release note on the GitHub repo and an in-app banner). Self-hosted servers are unaffected — they don't depend on the gateway for the desktop or iPhone paths (only for native APNs push).

Data

What we store, what crosses the wire, and how to delete it: see the Privacy page.

Governing law

These terms are governed by the laws of the United States of America, without regard to conflict-of-law provisions. Any dispute arising from these terms or your use of the push gateway will be resolved in the courts of the United States.
