Terms of Service
1. Who we are, who may use this
CumuloNimbus ("we", "us") provides a cloud companion service for the Nimbus device and a metered LLM router. You must be at least 18 years old and legally able to enter a contract to use the service. Access is currently invite-only. By creating an account or accepting these terms in the app you agree to them and to theAcceptable Use Policy and Privacy Policy, which are incorporated by reference. Business customers acting as a data controller are also offered our Data Processing Addendum.
2. Accounts and acceptance
You accept these terms by clicking to accept them in the product (clickwrap). We may publish a new version; when we do, we ask you to accept the new version before you continue with paid actions, and the effective version is shown above. Some paid actions require accepting the current version before they proceed.
3. Prepaid AI credits
- The LLM router is paid with prepaid credits you buy in advance. Credits are priced and charged in US dollars (USD): 1 credit = $0.01 USD of list value. Credits are a prepaid balance you spend on model usage; they arenot money, have no cash value, and are non-transferable.
- Credits expire 90 days after they are added to your balance. Each top-up or grant is its own 90-day batch, and your balance is spent oldest-expiring first. Unused credits in a batch are forfeited when that batch expires. Free credits we grant may carry a different expiry, which we show you at the time of the grant.
- Refunds. You may request a full refund of a credit purchase within24 hours of that purchase, no questions asked, for the portion you have not yet spent. After 24 hours, credit purchases arenon-refundable except where required by law. We may, at our discretion, issue a goodwill credit adjustment.
- If we terminate your account without cause (that is, not for your breach or for a legal or safety reason), we refund the unused portion of your prepaid credit balance, at its purchase value, within 30 days.
- Usage is metered and drawn from your balance. Because usage is metered after a call completes, a final call may draw your balance slightly negative; the shortfall nets against your next top-up. We never bill you more than you have paid in.
- Model pricing is estimated from provider list prices and may not reflect provider discounts (for example, caching); this can make your credits draw down somewhat faster than a provider's own discounted rate. A call may occasionally exceed a network gateway's response-time limit and be billed although you received a gateway timeout.
4. Subscriptions
Device access is sold as a subscription through Stripe. You can manage or cancel it in the billing portal. We may change prices with reasonable advance notice; a price change applies to the next renewal.
5. Your inputs and the LLM router
When you use the router, your inputs leave our system: your prompt and request are forwarded to the third-party model provider you addressed (for example, OpenAI, Anthropic, or Mistral), which processes them under its own terms. We forward using our own provider credentials and meter your usage. We do not train models on your inputs. What we retain, and the limited cases where a flagged request is stored for trust and safety, are described in the Privacy Policy.
6. Acceptable use and suspension
Your use must comply with the Acceptable Use Policy, which also requires you to comply with the usage policies of the upstream model providers your traffic is routed to. Those upstream policies flow down to you as part of these terms. We may suspend or terminate access for a violation, for suspected abuse, or where required by law, and (where safe and lawful) will tell you why.
7. The Nimbus device (hardware)
- Over-the-air updates. We may deliver firmware and configuration updates to your device over the air to fix, secure, or improve it. Some updates are needed to keep the cloud service working with your device, and installing them may be a condition of continued service. We aim to make updates reversible where practical.
- Support window. We support the current Nimbus hardware and, at a minimum, the prior hardware revision, for security and compatibility updates. Feature updates target the current revision.
- End of life. If we discontinue support for a hardware revision, we give at least 90 days notice. After end of life the device keeps its local functionality where it does not depend on the cloud service, but may lose cloud-dependent features.
- Export and consumer rights. Hardware and firmware may be subject to export controls; you agree not to export or re-export them contrary to applicable law. Nothing here limits the non-excludable warranty or consumer rights you have under the law of your jurisdiction.
8. Sanctions and export
You represent that you are not located in, and are not ordinarily resident in, a jurisdiction subject to comprehensive sanctions or embargo, and that you are not on a restricted-party list.
9. Changes to, and discontinuation of, the service
We may change the service over time. If we decide to discontinue the service, or a paid part of it, we give you at least 30 days notice by email or in the app, stop selling new credits for the affected part, and refund the unused portion of any prepaid credit balance at its purchase value, as described in section 3. Upstream model providers may change or withdraw models on their own timelines; where a model you use becomes unavailable, we route to an available one or tell you.
10. Disclaimers and liability
The service is provided "as is". Model outputs may be inaccurate; do not rely on them for professional advice. To the extent permitted by law, our aggregate liability is limited to the amount you paid us in the three months before the claim.
