Simmit seeks to be transparent and straightforward. Let us know if you have any questions at support@simmit.com or on Discord.

Last Updated: May 9, 2026

These Terms of Service ("Terms") are between Voidly Labs, a trade name of Void Platforms LLC, a Washington limited liability company with a principal place of business at [address] ("Company," "we," "us," or "our"), and you ("Developer," "you," or "your"). They govern your creation of a developer account and your access to and use of our application programming interfaces and related developer tools, documentation, dashboards, and services (the "API").

By clicking "Agree," creating a Developer Account, or otherwise accessing or using the API, you agree to these Terms. If you don't agree, don't create an account or use the API.

If you're accepting these Terms on behalf of an organization, you represent and warrant that you have the authority to bind that organization, and "Developer" refers to that organization.

#1. Eligibility and Accounts

1.1 Eligibility. To use the API, you must be at least 18 (or the age of majority in your jurisdiction, whichever is higher) and legally able to enter into these Terms. You also represent and warrant that you're not located in a country subject to comprehensive U.S. sanctions or embargoes and not on any U.S. government restricted-party list (including OFAC's SDN List or the Commerce Department's Entity List).

1.2 Organizational Accounts. If you create a Developer Account on behalf of an organization, you represent and warrant that you have the authority to bind that organization. The organization is responsible for all activity under the account, including activity by its employees, contractors, and other authorized users.

1.3 Developer Accounts. Access to the API requires a developer account (a “Developer Account”). Accounts are for your own use in connection with your applications or services. You're responsible for keeping your account information accurate and your credentials secure.

1.4 Account Responsibility. You're responsible for all activity under your Developer Account, including activity using your API keys or other credentials, whether authorized or not. Tell us promptly if you suspect unauthorized access.

1.5 Suspension and Termination. We may suspend or terminate your Developer Account as further described in Section 12 (Termination). If we've previously suspended or terminated you, you can't create a new account or access the API without our prior written consent.

#2. API Access and License

2.1 License Grant. If you comply with these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the API solely through an active Developer Account, for the purpose of running simulations and building applications that interact with our services. No other rights or licenses are granted by implication, estoppel, or otherwise.

2.2 Access Conditions. API access requires an active Developer Account, compliance with these Terms, and sufficient available Credits. We may suspend, limit, or revoke access at any time as set out in these Terms.

2.3 Rate Limits and Throughput. We may impose usage limits, rate limits, queueing, or other technical restrictions to protect system stability and fair use. Limits may vary by endpoint, workload, or time, and are shown in the Developer Dashboard or otherwise communicated. We may throttle, delay, deprioritize, or reject requests that exceed limits or strain system resources.

#3. Credits

3.1 Credit Types. You access the API by spending credits (“Credits”). There are three types: (a) “Signup Credits,” a one-time grant issued when you create a Developer Account; (b) “Monthly Credits,” recurring grants issued to verified accounts on the cadence in Section 3.6; and (c) “Purchased Credits,” credits acquired through our payment processor as described in Section 4. Signup Credits and Monthly Credits are referred to together as “Promotional Credits.”

3.2 Promotional Credits. Promotional Credits are issued at our discretion, have no monetary value, and can't be transferred, exchanged for cash, or resold. We may modify, suspend, revoke, or claw them back at any time without notice, including from accounts we reasonably believe have obtained Promotional Credits beyond intended per-account limits (for example, by circumventing verification). We reserve all rights and remedies available to us, including the right to recover the value of Promotional Credits obtained or consumed through circumvention.

3.3 Purchased Credits. Purchased Credits are sold in pack sizes and at prices shown at the time of purchase, denominated in U.S. dollars. They aren't transferable and aren't refundable except as set out in Section 4.3 or as required by law.

3.4 Consumption and Pricing. API operations consume Credits as described in the Developer Documentation. We may adjust per-operation Credit costs and pack prices at any time. We will announce material pricing changes through the Developer Dashboard, by email, or another reasonable means. Other adjustments may be made without individual notice. Pricing changes apply only going forward.

3.5 Credit Mechanics. Credit mechanics are described in the Developer Documentation and may be updated.

3.6 Verification. A Developer Account becomes “verified” once it completes our verification process, which is described in the Developer Documentation. Verified accounts may receive Monthly Credits and elevated usage limits. We may revoke verified status, suspend or terminate the account, and reclaim Promotional Credits if we reasonably believe it has been used to obtain Promotional Credits beyond intended per-account limits.

#4. Payments and Billing

4.1 Payment Processor. Purchases are processed by Stripe under Stripe's terms and privacy policy. We do not collect or store payment-card data. We retain limited transaction metadata necessary to operate, account for, and support purchases. Disputes about charges or card data go to Stripe; disputes about Credits provisioned to your account are handled by us.

4.2 Auto-Reload. You may opt in to automatic credit replenishment (“Auto-Reload”) through the Developer Dashboard. Enabling Auto-Reload authorizes us to charge the payment method on file according to the configuration you select. Auto-Reload is provided as a convenience and is not guaranteed to prevent service interruption from insufficient Credits. It's a discrete-purchase authorization, not a subscription. You can disable or modify Auto-Reload anytime through the Developer Dashboard, effective immediately for purchases not yet initiated. Auto-Reload behavior, including retry and failure handling, is described in the Developer Documentation.

4.3 Refunds. Purchased Credits are non-refundable once provisioned, except: (a) duplicate or erroneous charges; (b) Purchased Credits rendered unusable by an extended outage on our side, where the affected Credits are unconsumed; or (c) where required by law. We may issue additional refunds at our discretion as a goodwill matter. Promotional Credits are not refundable.

4.4 Taxes. Prices are exclusive of applicable taxes unless we say otherwise. Stripe Tax may collect and remit applicable taxes on our behalf where required; you're responsible for any taxes not so collected.

#5. Permitted Use and Restrictions

5.1 Permitted Use. You may use the API only through your Developer Account, only as described in our publicly available Developer Documentation, and only to develop, operate, and maintain applications that interact with our services in ways we permit. You may use the API to build, operate, and offer commercial applications and services, subject to the restrictions in this Section 5. Anything not expressly permitted under this Section 5 is prohibited.

5.2 Prohibited Conduct. You represent and warrant that you won't, and won't let anyone else:

access, probe, scrape, or reverse-engineer the API, our services, or any non-public functionality;
access, attempt to access, or use the API or our services without sufficient Credits or other authorization, or by bypassing, manipulating, or exploiting billing, credit, or usage-tracking mechanisms;
use scripts, bots, automation tools, or other automated means to access our services outside the API or to take actions not expressly permitted by our documentation;
interfere with, disrupt, degrade, or compromise the integrity, availability, or performance of the API or our services, including through stress testing, load testing, denial-of-service activity, or other conduct meant to overwhelm or impair our systems;
bypass, evade, disable, or otherwise circumvent usage limits, credit mechanisms, access controls, rate limits, verification requirements, or other technical or policy safeguards, including any attempt to obtain Promotional Credits beyond intended per-account limits;
resell, sublicense, lease, rent, share, or otherwise provide direct API access to any third party, including operating the API or our services as a standalone or proxied service;
use the API or Outputs to develop, train, improve, operate, or provide an API or backend service offered to third parties for executing SimulationCraft or substantially equivalent simulation workloads on demand;
systematically extract or redistribute Outputs to resell raw API access;
use the API or our services in any manner that is unlawful, deceptive, or misleading; or
misrepresent your relationship with us, including holding yourself out as our employee, partner, or official representative.
5.3 Use of Outputs. You may use the data, results, simulation outputs, calculation results, files, summary data, or other information produced through the API in response to your requests (the “Outputs”) only in connection with your permitted applications or services and subject to the restrictions in this Section 5.
5.4 Scope of Our Services. “Our services” includes the API, Developer Dashboard, documentation, and all other systems or services we operate in connection with the API.

#6. Inputs, Outputs, and Data

6.1 Inputs. "Inputs" means any data, parameters, configuration settings, or other information you or your applications submit to the API. As between us, you keep all rights in your Inputs, subject to the licenses granted in these Terms.

6.2 License to Inputs. You grant us a non-exclusive, worldwide, royalty-free license to host, process, transmit, and otherwise use Inputs as necessary to provide, maintain, secure, and improve the API and our services, including for monitoring usage, enforcing these Terms, and ensuring system integrity.

6.3 Outputs. "Outputs" means the results, data, or responses generated by the API based on Inputs. As between us, you own the Outputs generated from your Inputs, subject to the use restrictions in these Terms. We retain all rights in the API, our software, infrastructure, developer tools, and other Company-provided systems and services, except for any third-party or open-source software executed via the API, which remains under its own license. Nothing in these Terms transfers IP between the parties, and Outputs don't convey any ownership in our technology or services.

6.4 Storage and Retention. We may store Inputs and Outputs for limited periods as necessary to operate the API, comply with legal obligations, resolve disputes, or enforce these Terms. We aren't obligated to retain Inputs or Outputs for any minimum period unless we expressly agree in writing. Retention windows and the mechanism for retrieving Outputs are described in the Developer Documentation. You are responsible for controlling access to any retrieval URLs or credentials we provide and for any consequences of sharing them.

6.5 Privacy. You represent and warrant that you have all rights and permissions necessary to submit Inputs and that your use of the API complies with applicable data protection and privacy laws. To the extent Inputs contain personal data, our processing is governed by our Privacy Policy.

6.6 Open-Source Software. The API may execute or rely on third-party or open-source software, including SimulationCraft. That software is not owned by us and remains subject to its applicable open-source licenses. Nothing in these Terms is intended to limit, modify, or conflict with rights granted under those licenses. We don't claim any IP rights in SimulationCraft or its outputs.

#7. Support, Availability, and Changes

7.1 Support. We may make documentation, FAQs, or support channels available at our discretion. We don't guarantee any level of support, response time, or resolution. Any support is provided as-available.

7.2 API Availability. We'll use commercially reasonable efforts to make the API available, but we don't guarantee uninterrupted access, uptime, or error-free operation. The API may be unavailable from time to time due to maintenance, updates, system failures, capacity or resource constraints, network issues, or events outside our reasonable control.

The API is provided as described in Section 8 (Disclaimers). We don't make service-level commitments, uptime guarantees, or downtime credits, except as we may agree in writing.

7.3 Maintenance and Modifications. We may modify, suspend, or discontinue the API at any time, including by changing endpoints, features, functionality, rate limits, or usage requirements. We aren't required to give advance notice but may do so where reasonably practical. We don't guarantee backward compatibility or continued availability of any specific version, feature, or endpoint.

7.4 Third-Party Dependencies. The API may rely on third-party services, infrastructure, or data sources. We aren't responsible for outages, interruptions, or errors caused by them.

#8. Disclaimer of Warranties

8.1 As-Is; As-Available. THE API, DOCUMENTATION, OUTPUTS, AND ALL RELATED SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE. TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL IMPLIED WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, RELIABILITY, AND RESULTS. WE DO NOT WARRANT THAT THE API WILL BE UNINTERRUPTED, SECURE, TIMELY, OR ERROR-FREE, OR THAT DEFECTS WILL BE CORRECTED.

8.2 No Warranty as to Outputs. OUTPUTS ARE PRODUCED BY EXECUTING DEVELOPER-REQUESTED WORKLOADS AND MAY CONTAIN ERRORS, LIMITATIONS, OR INACCURACIES. WE DO NOT WARRANT THAT ANY OUTPUTS WILL BE ACCURATE, COMPLETE, RELIABLE, ERROR-FREE, OR FIT FOR ANY PARTICULAR USE.

8.3 No Reliance. YOU USE THE API AND OUTPUTS AT YOUR OWN RISK AND ARE SOLELY RESPONSIBLE FOR DECISIONS, ACTIONS, OR RESULTS YOU OBTAIN THROUGH THEM.

#9. Intellectual Property and Feedback

9.1 Our IP. The API, documentation, Developer Dashboard, our software and infrastructure, and other Company-provided systems and services (excluding SimulationCraft and other open-source software) are and remain our exclusive property. Except for the limited license expressly granted in these Terms, no rights are granted to you by implication or otherwise.

9.2 Credentials. You must keep your API credentials, keys, and tokens confidential and secure. Don't share, sublicense, disclose, or embed them in publicly accessible code, and don't let any third party access the API using your credentials. You're responsible for activity under your credentials and must tell us promptly about any suspected unauthorized use or compromise.

9.3 Injunctive Relief. A breach or threatened breach of these Terms relating to our IP, your credentials, or use restrictions may cause us irreparable harm for which monetary damages aren't adequate. We may seek injunctive or equitable relief, without posting bond, in addition to other available remedies.

9.4 Feedback. If you give us suggestions, ideas, or feedback about the API or services ("Feedback"), you grant us a perpetual, irrevocable, worldwide, royalty-free, sublicensable license to use, copy, modify, and otherwise exploit it for any purpose without obligation to you.

#10. Limitation of Liability

10.1 Exclusion of Certain Damages. TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, BUSINESS INTERRUPTION, OR SUBSTITUTE SERVICES, ARISING OUT OF OR RELATING TO THESE TERMS, THE API, OUTPUTS, OR YOUR USE OF (OR INABILITY TO USE) THE API, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY.

10.2 Liability Cap. TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS, THE API, OR OUTPUTS WILL NOT EXCEED THE GREATER OF (A) ONE HUNDRED U.S. DOLLARS (US$100) OR (B) THE TOTAL AMOUNTS YOU PAID US IN THE SIX (6) MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM. You acknowledge that these disclaimers, exclusions, and liability limits are a fundamental basis of the bargain. Nothing in these Terms limits liability to the extent prohibited by law.

#11. Indemnification

11.1 Your Indemnification. You'll defend, indemnify, and hold us (and our affiliates, officers, directors, employees, contractors, and agents) harmless from any claim, demand, action, damage, loss, liability, cost, or expense (including reasonable attorneys' fees) arising out of or relating to:

your use of the API or Outputs in violation of these Terms;
your applications, services, or content, including any claim that they infringe, misappropriate, or violate third-party rights;
your violation of applicable laws or regulations; or
your breach of these Terms.
11.2 Procedure. We'll give you prompt written notice of any covered claim (failure to give prompt notice doesn't relieve your obligation, except to the extent we're materially prejudiced). We may reasonably cooperate in the defense, at your expense. You can't settle any claim that imposes any obligation, admission, or liability on us without our prior written consent (not to be unreasonably withheld).
11.3 No Cap. Your indemnification obligations are independent of, and not subject to, the liability limits in these Terms, except where required by law.

#12. Termination

12.1 Term. These Terms remain in effect until terminated under this Section 12.

12.2 Termination by You. You may terminate at any time by closing your Developer Account and ceasing all API use.

12.3 Suspension and Termination by Us. We may suspend or terminate your access to the API or these Terms, in whole or in part, immediately and without prior notice if we reasonably suspect that you've violated these Terms; your use poses a security risk, legal risk, or risk of harm to us, the API, or third parties; you've engaged in misuse, abuse, or circumvention of usage limits, Credits, or access controls; or termination is required to comply with applicable law or a lawful governmental request.

12.4 Effect of Termination. When these Terms terminate or are suspended for any reason:

all licenses and rights granted to you immediately end;
you must stop accessing and using the API;
you may request deletion of Inputs and Outputs by emailing privacy@simmit.com; we'll process the request subject to our legal retention obligations; and
sections that by their nature should survive (intellectual property, disclaimers, liability limits, indemnification, governing law) survive.
12.5 Effect on Credits. If we terminate or suspend your access for cause (including for violations of Sections 5.2 or 12.3, fraud, or circumvention), you forfeit all unused Credits, including unused Purchased Credits, with no refund. If we terminate without cause (for example, by discontinuing the API), we'll either refund your unused Purchased Credits in cash or maintain a reasonable wind-down period for redemption, at our election. If you close your Developer Account, you may request a refund of unused Purchased Credits at support@simmit.com within thirty (30) days, granted at our discretion.
12.6 No Liability. We aren't liable to you or any third party for terminating or suspending access under this Section 12.

#13. Changes to These Terms

13.1 Modifications. We may modify these Terms from time to time by posting updates through the Developer Dashboard, our website, or other reasonable means. Unless we say otherwise, modifications take effect on posting.

13.2 Material Changes. For material changes, we'll use reasonable efforts to give notice by email, in-product notification, or through the Developer Dashboard. Non-material changes may be made without notice.

13.3 Acceptance. Your continued use of the API after the effective date of any modifications counts as acceptance. If you don't agree, stop using the API and close your Developer Account.

13.4 Developer Documentation. Where these Terms reference the Developer Documentation, that documentation describes current operational behavior and may be updated from time to time. The Developer Documentation does not modify the legal terms of this agreement.

#14. Confidentiality

14.1 Confidential Information. "Confidential Information" means non-public information we disclose to you in connection with the API or these Terms, whether oral, written, or electronic, including non-public documentation, technical specifications, credentials, security information, pricing, usage limits, and product plans. It does not include information you can demonstrate (a) is or becomes public through no fault of yours; (b) you lawfully knew before disclosure; (c) you lawfully received from a third party without restriction; or (d) you independently developed without reference to ours.

14.2 Obligations. You'll use Confidential Information only as needed to exercise your rights and perform your obligations under these Terms, and won't disclose it to any third party except to your employees or contractors who have a need to know and are bound by confidentiality obligations at least as protective as those here.

14.3 Public Discussion. Despite Section 14.2, you may publicly discuss your general impressions of the service, including in blog posts, social media, and community forums. You may not publicly disclose any non-public technical, operational, or business information about our services that we have not made public ourselves.

14.4 Protection. Use reasonable measures to protect Confidential Information from unauthorized access, use, or disclosure.

14.5 Compelled Disclosure. You may disclose Confidential Information to the extent required by law or court order, provided you give us prompt notice (where legally permitted) and cooperate in seeking confidential treatment or a protective order.

14.6 Injunctive Relief. Unauthorized disclosure or use of Confidential Information may cause us irreparable harm for which monetary damages may be inadequate, and we may seek injunctive or equitable relief in addition to other available remedies.

#15. Data and Privacy

15.1 Data. We may use technical, usage, and operational data from your use of the API in aggregated or de-identified form for analytics, service operation, security, and improvement.

15.2 Privacy. Our Privacy Policy describes how we collect, use, and disclose information in connection with the API and Developer Accounts. By using the API, you acknowledge our Privacy Policy governs.

15.3 Payment Data. Stripe collects and processes payment-card data under its own terms and privacy policy. We retain limited transaction metadata necessary to operate, account for, and support purchases. See Section 4.1.

#16. General

16.1 Governing Law and Venue. These Terms are governed by Washington law, without regard to its conflict-of-laws principles. Any legal action or proceeding arising out of or relating to these Terms or the API must be brought exclusively in the state or federal courts located in King County, Washington, and you consent to that personal jurisdiction and venue.

16.2 Independent Contractors. We're independent contractors. Nothing in these Terms creates a partnership, joint venture, agency, or employment relationship.

16.3 Entire Agreement. These Terms are the entire agreement between us about your access to and use of the API and supersede any prior or contemporaneous agreements on that subject.

16.4 Assignment. You may not assign or transfer these Terms without our prior written consent.

16.5 Severability and Waiver. If any provision is held unenforceable, the rest stays in effect. No waiver is effective unless in writing and signed by the waiving party.

16.6 Force Majeure. We aren't liable for any failure or delay in performance due to causes beyond our reasonable control.

16.7 Governing Language. These Terms are drafted in English, which controls.

16.8 Notices. We'll send any notices to the email address on your Developer Account. Keep that address current; notices are deemed received when sent.
