Terms of Service

Service: Reynolds, the hosted simulation service at api.tryreynolds.com, together with the web application at app.tryreynolds.com and any related APIs, clients and documentation (the "Service"), operated by Inviscid AI Co., a Delaware corporation, 2261 Market Street STE 46104, San Francisco, CA 94114, United States ("we", "us"). By creating an account or using the Service you accept these terms.

1. What the Service is, and is not

We run OpenFOAM cases you submit, on isolated per-user instances, and store the files and results you put there. We provide compute and storage only. We do not review your cases, we do not check your physics, and we make no representation or warranty that any mesh, solve, figure, number or written conclusion produced through the Service is correct, converged, appropriate to your problem, or fit for any purpose.

Nothing produced by or through the Service is engineering advice, a professional opinion, or a substitute for qualified engineering judgement, and it must not be relied on for any design, safety, certification, regulatory or commercial decision without independent verification by a competent engineer. Judging a simulation is your job. You are solely responsible for any use you make of anything the Service produces, and for any consequence of that use.

The Service includes automated components that use machine-learning models. Those models can be wrong, can be confidently wrong, and can behave differently from one run to the next on identical input.

2. Your account

You need an account. You are responsible for your credentials, for every API key minted for your account, and for everything done with them, whether or not you authorised it. Revoke a key the moment you think it has leaked. One person per account; do not share accounts. You must be old enough to form a binding contract where you live, and if you use the Service for an organisation you warrant that you may bind it.

3. Acceptable use

Instances are for running CFD and related pre- and post-processing. You must not use them to attack, scan, or mine; to store, process or distribute content you have no right to; to process personal data of others without a lawful basis; to build a competing service; or to circumvent the limits we set (concurrency, budget, disk, rate limits). Network egress from instances is disabled by default and you must not attempt to defeat that. We may suspend or terminate an account that breaks these rules, immediately and without notice.

4. Plans, budgets, limits, fees

Usage is metered while an instance is running and, where you use a model we provide, per token. Each account has a monthly budget; when it is used up, new compute is refused until the budget resets or is raised. Metering as recorded by the Service is the record of what you used. We may change limits, plans and prices at any time, with 30 days' notice for paid plans; free-plan and trial limits may change at any time without notice. Fees are non-refundable except where the law requires otherwise.

5. Your content, and what we may do with it

"Your Content" means the files on your instances and everything you put in the capture plane — studies, messages, prompts, model outputs, results and artifacts. As between you and us, Your Content is yours, and you warrant that you have the rights to it.

You grant us a worldwide, non-exclusive, royalty-free, fully paid, sublicensable and transferable licence to host, store, copy, transmit, display, process and analyse Your Content, and to create derivative works of it, for the purposes of:

• providing, operating and supporting the Service;
• securing the Service, investigating abuse and enforcing these terms;
• meeting our legal obligations; and
• developing, evaluating and improving the Service and our other products, including the models, prompts, tooling and datasets used in them.

We may access Your Content where reasonably necessary for any of those purposes, including by automated means. Where we use Your Content for the last purpose we will use commercially reasonable efforts to de-identify or aggregate it first, and we will not publish Your Content in identifiable form.

No durability guarantee. We do not promise that Your Content will be retained, and we do not operate the Service as a backup or system of record. Instances have a hard 24-hour lifetime, idle instances are stopped, and data can be lost through failure, deletion, suspension, or termination of your account or of the Service. Keep your own copies of anything you cannot afford to lose. Deleting an instance destroys its data immediately and irreversibly. Deleting your account removes Your Content as described in the Privacy Policy, subject to backups and to anything we must keep by law.

6. Third-party services and your own keys

The Service runs on infrastructure operated by third parties, and it can be pointed at model providers of your choosing. Where you supply your own model provider key, the client calls that provider directly and your agreement with that provider governs that traffic; where you use a model we provide, that traffic passes through the Service and is metered. We are not responsible for any third party's acts, omissions, availability, pricing or terms.

7. Availability, warranties, and liability

The Service is provided "as is" and "as available". To the fullest extent permitted by law we disclaim all warranties, express or implied, including any warranty of merchantability, fitness for a particular purpose, accuracy, non-infringement, and any warranty arising from course of dealing or usage. We do not warrant that the Service will be uninterrupted, timely, secure or error-free, or that any result will be accurate or reliable.

To the fullest extent permitted by law, we are not liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for lost profits, lost revenue, lost data, lost results, lost time, business interruption, or the cost of substitute services, however caused and on any theory of liability, even if we have been advised of the possibility.

Our total aggregate liability arising out of or relating to the Service or these terms is limited to the lesser of (a) the fees you paid us in the three months before the event giving rise to the claim and (b) US$100.

Some jurisdictions do not allow some of these exclusions; where that is so, they apply to the maximum extent permitted, and nothing here limits liability that cannot lawfully be limited.

8. Indemnity

You will defend, indemnify and hold us harmless from any claim, loss, liability, damage, penalty or expense (including reasonable legal fees) arising out of Your Content, your use of the Service, your breach of these terms, or any reliance — by you or by anyone you give a result to — on anything the Service produced.

9. Termination

You may stop using the Service at any time and delete your account. We may suspend or terminate your access, or discontinue the Service in whole or in part, at any time, with or without cause and with or without notice. Sections 1, 5, 7, 8 and 10 survive termination.

10. Changes, and everything else

We may change these terms at any time by posting a revised version; for material changes we will make reasonable efforts to notify you. Your continued use after a change takes effect is your acceptance of it. If a provision is unenforceable the rest stands. We may assign these terms, including to a successor in a merger or sale of assets; you may not. These terms are the entire agreement between us about the Service.

These terms are governed by the laws of the State of Delaware, without regard to its conflict-of-laws rules. Any dispute about them or the Service goes to the state or federal courts located in Delaware, and you and we each consent to those courts' jurisdiction. This does not take away any mandatory right you have under the law of the place you live.
