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 720 Seneca St Ste 107 #970, Seattle WA ("Company," "we," "us," or "our"), and you ("Account Holder," "you," or "your"). They govern your creation of an account (your "Account") and your access to and use of our application programming interfaces and related tools, documentation, dashboard (the "Dashboard"), and services (the "API").
By clicking "Agree," creating an 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 accept these Terms for an organization, you represent and warrant that you have authority to bind it; "Account Holder" then refers to the organization, which is responsible for all activity under its Account, including by its employees, contractors, and other authorized users.
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 that you're not located in a country subject to comprehensive U.S. sanctions or embargoes and aren't on any U.S. government restricted-party list.
1.2 Accounts. Access to the API requires an Account. Usage limits are set by tiered usage policies (Section 2.2); tiers set operational limits only and don't change what you're permitted to do. Accounts are for your own use, and you're responsible for keeping your account information accurate and your credentials secure.
1.3 Account Responsibility. You're responsible for all activity under your Account, including activity using your API keys or other credentials, whether authorized or not. Tell us promptly if you suspect unauthorized access.
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 through an active Account with sufficient available Credits: (a) for your own purposes, including running simulations and using third-party applications or tools you've chosen to use; and (b) to build, operate, and offer your own applications and services that interact with the API, as described in Section 5. No other rights or licenses are granted by implication, estoppel, or otherwise.
2.2 Rate Limits and Throughput. We may impose usage limits, rate limits, queueing, or other technical restrictions to protect system stability and fair use. Limits are set by tiered usage policies and may vary by tier, endpoint, workload, or time; current limits are shown in the Dashboard. We may change tier policies at any time. We may throttle, delay, deprioritize, or reject requests that exceed limits or strain system resources.
3.1 Credits. You access the API by spending prepaid credits ("Credits"). API operations consume Credits as described in the Documentation, and we apply Credits in the order described there. Credits are either "Purchased Credits," which you buy as described in Section 4, or "Promotional Credits," meaning any Credits we grant without charge (e.g., signup grants, promotional bonuses, recurring allowances for verified accounts, or goodwill credits), however issued.
3.2 Promotional Credits. Promotional Credits are issued at our discretion, and amounts, eligibility, and cadence may change at any time. They 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, including recovering the value of Promotional Credits obtained or consumed through circumvention.
3.3 Purchased Credits. Purchased Credits are sold in the pack sizes and U.S.-dollar prices shown at purchase. They aren't transferable and aren't refundable except as set out in Section 4.3 or as required by law. Purchased Credits don't expire.
3.4 Expiration. Promotional Credits may carry an expiration date, shown when granted or in the Dashboard. Expired Credits are forfeited without refund or compensation.
3.5 Pricing. API operations consume Credits as described in the Documentation. We may adjust per-operation Credit costs and pack prices at any time. We will announce material pricing changes through the Dashboard, by email, or another reasonable means. Pricing changes apply only going forward.
3.6 Verification. An Account becomes “verified” by completing the verification process described in the Documentation. Verified accounts may receive recurring Promotional Credit allowances and elevated usage limits. If we reasonably believe an Account has obtained Promotional Credits beyond intended per-account limits, we may revoke its verified status, in addition to our rights under Section 3.2.
4.1 Payment Processor. Purchases are processed by Stripe under Stripe's terms and privacy policy. We don't collect or store payment-card data, only limited transaction metadata needed to operate 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 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 Dashboard, effective immediately for purchases not yet initiated. Auto-Reload behavior, including retry and failure handling, is described in the 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.
5.1 Permitted Use. You may use the API only through your Account and as described in our publicly available Documentation. Subject to the restrictions in this Section 5, you may: (a) use the API and Outputs for your own purposes, including through third-party applications or tools you've chosen to use; and (b) build, operate, and offer your own applications and services that use the API, including commercial ones serving your own customers. Use by your applications is billed to your Account, except usage under an end user's own API key (Section 9.3), which is billed to that user's Account, and you're responsible for your applications and their end users. 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;
interfere with, disrupt, degrade, or compromise the integrity, availability, or performance of the API or our services, including stress testing, load testing, or denial-of-service activity;
bypass, evade, disable, or otherwise circumvent billing, credit, or usage-tracking mechanisms, usage or rate limits, access controls, verification requirements, or other technical or policy safeguards — including using the API without sufficient Credits, obtaining Promotional Credits beyond intended per-account limits, or obtaining Outputs or simulation execution from our systems through any means outside the metered API;
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;
knowingly provide API access, through your application or otherwise, to anyone whose Account we've suspended or terminated; or
attempt, or assist anyone else in, any of the above.
5.3 Use of Outputs. You may use Outputs (defined in Section 6.3) only as permitted by this Section 5.
5.4 Scope of Our Services. “Our services” includes the API, the Dashboard, documentation, and all other systems or services we operate in connection with the API.
6.1 Inputs. "Inputs" means anything you or your applications submit to the API. You keep all rights in your Inputs, subject to the licenses in these Terms.
6.2 License to Inputs. You grant us a non-exclusive, worldwide, royalty-free license to host, process, and use Inputs as necessary to provide, maintain, secure, and improve the API and our services and to enforce these Terms.
6.3 Outputs. "Outputs" means the results, data, or responses the API generates from your Inputs. You own your Outputs, subject to the use restrictions in these Terms. We retain all rights in the API and our software, infrastructure, and tools, except third-party or open-source software executed via the API, which stays under its own license.
6.4 Storage and Retention. We may store Inputs and Outputs for limited periods as necessary to operate the API, comply with law, resolve disputes, or enforce these Terms, and we aren't obligated to retain them unless we expressly agree in writing. Retention windows and the mechanism for retrieving Outputs are described in the Documentation. You're responsible for controlling access to any retrieval URLs or credentials we provide.
6.5 Privacy. You represent that you have the rights needed 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 remains subject to its own open-source licenses, we claim no IP rights in it or its outputs, and nothing in these Terms limits rights granted under those licenses.
7.1 Support. We may offer documentation, FAQs, or support channels at our discretion. Support is as-available, with no guaranteed response or resolution.
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, system failures, capacity constraints, outages of third-party services we rely on, 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, and we don't guarantee backward compatibility or continued availability of any version, feature, or endpoint.
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.
9.1 Our IP. The API, documentation, the 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, except as described in Section 9.3 (Bring Your Own Key).
9.3 Bring Your Own Key. If you connect your API key to third-party applications and services built on the API, you do so at your own risk: we don't vet, endorse, or control third-party applications, you remain responsible for all activity and Credit spend under your key, and exposure of your key through a third-party application (including browser-based ones) is your risk. A third-party application's handling of your data is governed by its terms and privacy policy, not ours. We may revoke, or require rotation of, keys we reasonably believe are compromised.
9.4 Injunctive Relief. A breach or threatened breach of these Terms involving our IP, your credentials, or the use restrictions may cause us irreparable harm, and we may seek injunctive or equitable relief, without posting bond, in addition to other remedies.
9.5 Feedback. If you send us suggestions or feedback, you grant us a perpetual, irrevocable, worldwide, royalty-free, sublicensable license to use it for any purpose without obligation to you.
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.
11.1 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 notice of any covered claim; late notice doesn't relieve your obligations except to the extent the delay materially prejudices your defense. We may participate 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 aren't subject to the liability limits in these Terms, except where required by law.
12.1 Term. These Terms remain in effect until terminated under this Section 12. You may terminate at any time by closing your Account and ceasing all API use.
12.2 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 you've violated these Terms; your use poses a security, legal, or harm risk to us, the API, or third parties; you've misused or circumvented usage limits, Credits, or access controls; or termination is required to comply with applicable law or a lawful governmental request. If we've suspended or terminated your Account, you may not create a new account or access the API without our prior written consent. We may also terminate these Terms or your access to the API for any or no reason on thirty (30) days' notice to you, in which case Section 12.4's without-cause provisions apply.
12.3 Effect of Termination. When these Terms terminate or are suspended for any reason, all licenses and rights granted to you immediately end and 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. Sections that by their nature should survive (intellectual property, disclaimers, liability limits, indemnification, governing law) survive.
12.4 Effect on Credits. If we terminate or suspend your access for cause (including for violations of Sections 5.2 or 12.2, 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 Account, you may request a refund of unused Purchased Credits at support@simmit.com within thirty (30) days, granted at our discretion.
12.5 No Liability. We aren't liable to you or any third party for terminating or suspending access under this Section 12.
13.1 Modifications. We may modify these Terms from time to time by posting updates through the Dashboard, our website, or other reasonable means. Unless we say otherwise, modifications take effect on posting. For material changes, we'll use reasonable efforts to give notice by email, in-product notification, or the Dashboard. Your continued use of the API after the effective date counts as acceptance; if you don't agree, stop using the API and close your Account.
13.2 Documentation. The Documentation describes current operational behavior, may be updated at any time, and doesn't modify these Terms.
14.1 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.
14.2 Privacy. Our Privacy Policy describes how we collect, use, and disclose information in connection with the API and Accounts. By using the API, you acknowledge our Privacy Policy governs.
15.1 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.
15.2 Miscellaneous. We're independent contractors; these Terms don't create a partnership, joint venture, agency, or employment relationship. These Terms are the entire agreement between us about your access to and use of the API and supersede prior agreements on that subject. You may not assign these Terms without our prior written consent. If any provision is held unenforceable, the rest stays in effect; no waiver is effective unless in writing and signed. We aren't liable for failure or delay due to force majeure causes beyond our reasonable control. These Terms are drafted in English, which controls. We'll send notices to the email address on your Account and notices are deemed received when sent to such email address.
