Terms of service

Last updated 15 November 2026

These terms are an agreement between you and Tera Labs USA LLC ("we") about the TERAOS app for Mac and TeraCloud, the service behind it. By creating an account or using TERAOS, you agree to them. Our privacy policy explains how we handle your data.

Your account

You sign in with Apple or Google. Keep access to that account safe: anyone who can sign in to it can use your TERAOS account. You must be at least 13, and old enough to agree to these terms where you live. You can delete your account at any time from the app.

Plans and billing

• TERAOS has a free plan and paid plans. Each plan includes a number of talk turns and agent messages per billing period, shown in the app and in your account. Usage beyond a plan's limits waits for the next period or a plan change.
• Each plan also has a fair-use limit on what its requests may cost us. If you reach it, cloud features pause until the next period, and the app tells you so.
• Paid plans renew monthly until you cancel. Payments are processed by Stripe. You can change plans, update your card or cancel from Manage billing; a cancellation takes effect at the end of the period you've paid for.
• We may change prices or plan limits. We'll tell you before a change applies to your plan, and you can cancel before it does.

Using TERAOS

You may use TERAOS for any lawful purpose. You may not use it to:

• break the law or infringe anyone's rights,
• access accounts, devices or data you aren't allowed to,
• send spam or harass anyone,
• get around plan limits, resell access to TeraCloud, or interfere with the service,
• do anything Anthropic's usage policy forbids, since requests are answered by Claude.

We may suspend an account that breaks these rules or puts the service or other people at risk.

When TERAOS acts for you

TERAOS can operate your Mac, your Chrome browser and the apps you connect. It asks for your approval before actions that change something, and shows what it's about to do. You're responsible for the actions you approve. Check what TERAOS has done, especially before anything important or hard to undo.

AI answers can be wrong

TERAOS uses AI models to understand you and answer. Answers can be incomplete, out of date or wrong. Don't rely on them for medical, legal, financial or safety decisions without checking.

Your content

What you say to TERAOS, what it answers, and the data in your connected apps are yours. You give us permission to process that content only as needed to run TERAOS for you, as described in the privacy policy. We don't claim ownership of it.

Other services

Connected apps (Google, Slack, Microsoft), sign-in providers (Apple, Google), Anthropic and Stripe are run by other companies under their own terms. We aren't responsible for their services, and an outage or a change on their side may affect what TERAOS can do.

Changes and availability

We keep improving TERAOS and may add, change or remove features. We aim to keep TeraCloud available, but we don't promise it will always be. If we make a change to these terms that matters, we'll tell you in the app or by updating this page, and the date above, before it takes effect.

Disclaimer and limits of liability

TERAOS is provided "as is" and "as available". To the extent the law allows, we disclaim warranties of merchantability, fitness for a particular purpose and non-infringement. To the extent the law allows, we aren't liable for indirect, incidental or consequential damages, or for lost data or profits, and our total liability for any claim is limited to what you paid us in the 12 months before it. Some places don't allow these limits, so they may not apply to you.

Ending the agreement

You can stop using TERAOS and delete your account at any time. We may end these terms or your access if you break them, with notice where we can give it. The sections on liability, your content and disputes continue after the agreement ends.

Governing law

These terms are governed by the laws of the state in which Tera Labs USA LLC is organized, in the United States, without regard to conflict-of-law rules, except where the law where you live says otherwise.
