Terms of service

LAST UPDATED · 2026-05-28

These terms cover Mayva's hosted service (Personal, Pro, Teams) and the mayva.ai website. The local source code is governed by the MIT license in the repo.

1. The service

"Mayva" is a personal agent system. Hosted on subscription; open-source under MIT for local use. These terms apply to the hosted version only.

2. Your account

You're responsible for your account credentials. Don't share them. Tell us promptly if you suspect unauthorized access. We may suspend accounts for clear abuse, but we'll always tell you why.

3. Acceptable use

  • Don't use Mayva for anything illegal.
  • Don't try to extract other tenants' data. Each tenant is keyed and isolated.
  • Don't abuse the integrations. Their terms apply, too.
  • Don't deliberately overload our infrastructure.

4. Subscriptions and billing

Subscriptions are billed monthly via Stripe in advance. LLM tokens are billed monthly in arrears, at cost (no markup). Cancel anytime — you keep access through the end of the current billing period.

5. Early access

We're in early access. Features may change. We'll communicate breaking changes well in advance, but we reserve the right to iterate the product significantly before general availability.

6. Your content

You own the data you put into Mayva. By using the service, you grant us a license to store, process, and transmit it as needed to run the service — including sending the necessary portions to Anthropic so the agent can reason about it.

7. Our content

The Mayva trademark, the marketing site copy, and the visual design are ours. The source code in the open-source repo is MIT and governed by its license.

8. Service availability

We aim for 99.5% monthly uptime on Personal, 99.9% on Pro and Teams. We don't currently offer SLA credits to Personal subscribers; Pro and Teams customers can negotiate one.

9. Termination

Either of us can terminate at any time for any reason. If we terminate without cause, we'll refund the remainder of the current billing period.

10. Disclaimers

Mayva reads your wearable data and adjusts its tone. It is not medical advice. It is not a substitute for talking to a doctor.

11. Liability

Our total liability for any claim is limited to the amount you paid us in the 12 months preceding the claim. We're not liable for indirect damages or consequential losses.

12. Changes to these terms

If we make material changes, we'll email you and post the new version with an updated date. Continued use after that means you accept the changes.

13. Governing law

These terms are governed by the laws of Delaware, USA. Disputes go to courts in San Francisco, California.
