# Terms of service

Updated 3 November 2026.

These terms apply when you use ace's apps or the services we run for them: the ace account, the hosted relay, the push gateway, this website and the web app. By using them, you agree to these terms.

## The software

ace's source code is open source under the Apache-2.0 license, and that license governs the code: you may use, change and share it under its terms. These terms cover the services we host. You can run ace without them, or run your own relay instead of ours.

## Your account

Give accurate information when you sign in, keep your sign-in methods secure, and tell us if you think someone else has used your account. You are responsible for what happens under your account.

A device signed in to your account can control every machine on it, unless that machine has a machine code. Set a machine code on machines that matter, and turn on multi-factor sign-in where you can.

## Your machines and your agents

ace runs coding agents on computers you control, through CLIs you install and sign in to. You decide what those agents may do, and you are responsible for their actions on your machines and for following the terms of each agent's provider. ace doesn't control those providers or their models, and isn't responsible for their output.

## Acceptable use

Don't use ace's services to:

- break the law, or infringe anyone's rights;
- reach machines, accounts or data that aren't yours, or that you aren't allowed to use;
- spread malware, or attack, probe or overload any system, ours included;
- use the relay for anything other than connecting your own devices to your own machines;
- get around rate limits, access checks or other protections.

## The services

The hosted services are currently free, and offered as they are. We may change them, limit their use, or stop offering them, and they may sometimes be unavailable. When the relay is down, connections over your local network, Tailscale or your own relay keep working.

## Ending your use

You can stop using the services and ask us to delete your account at any time (see the privacy policy). We may suspend or close an account that breaks these terms or puts the services or other people at risk, and, where we reasonably can, we will tell you why.

## Third-party services

Signing in uses WorkOS, and Google or GitHub if you choose them. The services run on Cloudflare, and notifications go through Apple. Your coding agents connect to their own providers. Each of these has its own terms, which apply to your use of it.

## No warranty

ace and its services are provided "as is" and "as available", without warranties of any kind, express or implied, including fitness for a particular purpose and non-infringement. We don't promise that they will be uninterrupted, secure or free of errors.

## Limitation of liability

To the extent the law allows, ace and its contributors are not liable for any indirect, incidental, special or consequential damages, or for lost data, profits or work, arising from your use of ace or its services. Our total liability for any claim about the services is limited to 100 US dollars.

## Changes to these terms

We may update these terms. We will change the date at the top and, for significant changes, say so on this site or in the app before they take effect. If you keep using the services after that, the new terms apply.
