Terms of Service

Last updated 13 October 2026

The short version: GOL offers one product, Check. It charges US$0.02 per message you send after a 14-day free trial, a price we will never raise. Prepaid credits never expire and stay honoured (sections 3 and 15). Nothing in these terms takes away the rights the Australian Consumer Law gives you.

1. Who we are

GOLProductions ("GOL", "we", "us") operates golproductions.com and the products available through it. You can reach us any time at [email protected].

2. Eligibility

You must be at least 18 years old (or the age of majority in your jurisdiction) to use GOL products. By creating an account, you represent that you meet this requirement. If you use GOL products on behalf of a business, you represent that you have authority to bind that business to these terms.

3. What you are buying

GOL offers one product, Check. It is usage-based, paid in US dollars, and draws from a prepaid balance (your "GOL wallet") after a 14-day free trial. One GOL account, signed in at golproductions.com, gives access to it. Unused prepaid credits never expire and remain honoured.

  • Check is an anti-hallucination layer that checks the commands and file writes an AI makes against your real machine before they run. It is billed per message: US$0.02, a price locked for good. A message is one message you send to your AI. It is charged once whether Check runs no checks or many while the AI answers it; every check inside it is included. When you send a message, Check tells our server only that a message happened, using the identifier your AI tool gives it; the text of your message is never read by us or sent to us. Syntax errors are always free: if your own terminal finds a syntax error in a command, Check returns that verdict without contacting our server. 14 days free from the moment you create your GOL API Key at the console (see section 4 for limits). Check runs on Windows and Linux. macOS is not yet verified by us on the hardware it runs on, so the installer refuses to proceed there; if you want to help verify it, email support. Check keeps itself current: the part installed on your machine downloads updates from our server in the background, at most once an hour, and uses an update only if it matches the fingerprint (SHA-256) our server states and it parses.
  • Check pricing is shown on the pricing page and in the console before you pay anything.
  • Credits never expire and remain in your account until used.
  • A request that fails to complete is not charged.

4. Free trial

Check: 14 days free, counted from the moment you create your GOL API Key at the console. Keys are made only at the console, by a signed-in account with two-factor authentication. A message is one message you send to your AI, charged once whether Check runs no checks or many in it. During the trial, use is capped per key, per device fingerprint and per network IP as a guard against abuse. After the trial, each message costs US$0.02 (GST inclusive where GST applies) from your prepaid balance, charged once however many checks it contains. Price lock: we will never raise the price per message above US$0.02. Keys created before 14 October 2026 had 120 free messages a day; from 14 October 2026 they have a 14-day trial ending 28 October 2026, then pay per message like every key. Balances loaded before 14 October 2026 were in Australian dollars and were converted to US dollars so that each keeps exactly the number of messages it bought: US$ = A$ ÷ 0.0068 × 0.02. Installs made before version 4.3.0 do not report messages, so each of their checks counts as one message. Syntax errors your own machine finds before contacting the server are not charged.

Free allowances for Check are limited to one account per person and one account per device. Creating multiple accounts or circumventing device detection to obtain additional free messages is a violation of these terms and may result in account suspension.

5. What the products do and do not do

Check verifies whether commands and syntax are valid against your actual environment. Results are factual assessments, not certifications: they do not guarantee that any target is reachable, secure, or compliant with any standard. Results will vary depending on the AI model you use, your project structure, your environment, and how the model generates its output. Check compares what your AI is about to do against what exists at the moment of the check: on your machine (programs, files, folders, git, parsers), in the public package registries, and, for deletes, where the folder that would really be removed sits relative to your drive, home folder and project. Nothing more, nothing less.

Check is designed to fail open rather than block your work. When your free trial has ended and your balance is empty, when the validation service cannot be reached, or when your installed version is too old for our server, commands proceed without validation and Check surfaces a warning where the environment allows it.

Check is provided "as is" and "as available" to the maximum extent permitted by law, subject always to your rights under the Australian Consumer Law (section 8). We do not warrant uninterrupted availability, and scheduled or unscheduled maintenance may temporarily affect access to Check.

You remain responsible for decisions you make based on product output. We do not and cannot guarantee any specific outcome, detection rate, or level of accuracy.

We are working to improve our products all the time. If you experience an issue or something does not work as expected, please email [email protected] so we can investigate and resolve it.

5A. Your AI model, and what our products provide

Check connects your AI to the machine you already use. It reports what your system says, such as whether a program exists, and adds nothing of our own. It does not write, choose or run your AI's actions. When Check blocks a command, it reports your machine's answer; what your AI does next is decided by your AI and by you. Responsibility for your AI's output and actions remains with you and with your AI's provider, under that provider's terms. GOLProductions makes no representation about the accuracy, safety or suitability of any AI model's output.

5B. Legacy: withdrawn products

What happened. Envie (AI video rendering) and Exnos (live browser state for AI coding agents) were free tools we released from July 2026, first through npm and GitHub. Depending on the version, copies were released under the MIT License, the GOL Open License or the GOL Free License. On 12 October 2026 we withdrew both: we unpublished them from npm, made their source private, stopped distributing them from this website, and removed them from our product range. We no longer offer, update or support either tool.

If you already have a copy, you may use it within the rights its licence gives you. It keeps working and stays free, and we will not switch it off or limit it. Exnos and Envie 0.8.0 and later never contact our servers. Envie versions before 0.8.0 ask our server for a free render grant before each render; we keep that service running so those copies keep working, and it stores nothing. Each copy remains under the licence in its own LICENSE file, and these terms add no restriction to the rights that licence grants. Exnos passes browser content only to the AI tool on your machine that asked for it; that tool may send it on to its own provider, under that provider's terms.

Refunds. Early Envie versions described a $3.00 AUD charge for a watermark-free render. If you were ever charged, email [email protected] and we will refund it.

AI Assistant and the Hallucination Checker. We also withdrew AI Assistant (a chat assistant for business websites) and the Hallucination Checker (a subscription that checked AI text against your documents) on 12 October 2026. No customer had paid for either. If you believe you were charged for either, email [email protected] and we will refund it.

"Envie" and "Exnos" remain trademarks of GOLProductions. Nothing in this section limits your rights under the Australian Consumer Law.

6. Your account

Sign-in uses your email address and a single-use code. You are responsible for:

  • Keeping access to your email account secure.
  • Safeguarding your API key and not sharing it with third parties.
  • All activity that occurs under your API key, whether or not you authorised it.

If you believe your key has been compromised, rotate it immediately from the console or contact us. You may also revoke all active sessions from the console. We will not be liable for unauthorised usage that occurs before you notify us or rotate your key.

7. Payments

This section applies to Check. Payments are processed by Stripe. We never see or store your card details. Top-ups are credited to your account automatically once Stripe confirms payment.

  • Check minimum top-up: US$5.00. Maximum top-up: US$500.00 per transaction. Prices and balances are in US dollars.
  • Prices are in US dollars and, where GST applies, are GST inclusive.
  • Check top-ups are one-time payments. Nothing auto-recharges them, so the most that can ever be spent is the balance you loaded. There are no recurring charges.
  • The price per message is locked: we will never raise it above US$0.02. We may lower it. Any other change to our prices applies only to new purchases, never to credits already in your wallet, and if a change disadvantages you, section 17 lets you stop and be refunded.

8. Refunds and your Australian Consumer Law rights

Our services come with guarantees that cannot be excluded under the Australian Consumer Law. Nothing in these terms excludes, restricts or modifies those guarantees or any other right you have under law that cannot lawfully be changed by agreement. The Australian Consumer Law is administered by the Australian Competition and Consumer Commission (ACCC) together with the state and territory consumer protection regulators. If you believe a consumer guarantee has not been met and we have not put it right, you can also raise it with the ACCC or your local consumer protection agency.

  • Where a service we supply fails to meet a consumer guarantee, you are entitled to the remedies the law provides, which may include a refund.
  • Outside of those rights, requests that completed successfully are not refundable. The compute was performed and the cost was incurred.
  • Unused credits are non-refundable and remain honoured indefinitely in your account, including if you stop using the service.
  • If we ever permanently discontinue a product, we will notify affected users and refund unused credits attributable to that product.
  • Refund requests under consumer guarantees should be sent to [email protected]. We aim to process valid claims within 10 business days.

9. Intellectual property

What you make is yours. We claim no ownership of, and no licence over, anything you create while using Check: your prompts, your commands and your code. You own your output and may use, publish, distribute and sell it freely, commercially or otherwise, with no attribution to GOL required and no royalty owed. What we keep from your use of Check, and your switch for it, is set out in section 12. Nothing in the rest of this section takes any of that back.

What follows describes our own software, not your work.

"Check", "Envie", "Exnos", the GOL name, the GOL logo, and all associated software, algorithms, compiled binaries, validation engines, documentation, test suites, and trade secrets are the exclusive intellectual property of GOLProductions. All rights are reserved worldwide.

  • You may not copy, reproduce, modify, reverse-engineer, decompile, disassemble, or create derivative works of any proprietary GOL software, including the Check API, compiled binaries, SDKs, or validation engines.
  • You may not use Check, its protocols, or its outputs to build, train, or operate a competing verification or validation service.
  • Client packages (npm) are provided for use exclusively with the GOL APIs. Source availability of an installer does not imply an open-source licence over the compiled components or server-side logic.
  • You may not scrape, crawl, or systematically extract data from GOL APIs or the website beyond normal product usage.
  • Feedback and suggestions you provide may be incorporated into GOL products without obligation or compensation.

10. Acceptable use

You agree not to:

  • Use GOL products to facilitate any activity that violates applicable law.
  • Resell, redistribute, or sublicense API access without our written agreement.
  • Attempt to disrupt, overload, or interfere with the service, including circumventing rate limits or security controls.
  • Attempt to reverse-bill, fraudulently obtain credits, or exploit billing logic.
  • Share your API key publicly or embed it in client-side code where it can be extracted.
  • Create automated or bot-driven accounts to obtain additional free messages or credits.
  • Use the service to probe, scan, or attack third-party systems in a manner not authorised by the owner of those systems.
  • Present an output to another person as a guarantee of truth or as having been certified by us.

We may suspend or terminate accounts engaged in abuse. If we do, we will tell you why. Unused credits on a terminated account will be refunded except where they were obtained fraudulently or where the account was used to violate these terms.

11. Rate limits and daily caps

The command-checking endpoint allows 60 requests per minute, Check counts up to 30 messages per minute, and account endpoints have lower limits. We may adjust rate limits and free allowances only where reasonably necessary to protect service quality, security or other users, and we will give notice of material changes. If a change materially reduces something you have paid for, section 17 applies and you may cancel and be refunded.

12. Privacy

We collect only what each product needs to work, plus your account email and how you first found us. The text of your messages and the contents of your files never reach us. We keep a record of each check (the time, a one-way hash of your key, your network address, Check's version, which AI tool asked, and the verdict). Improvement records: for keys created from 14 October 2026, we also keep, by default, the command your AI was about to run (with credentials removed), the name of a file it was about to write, and the reason Check gave, to make Check better. You can switch improvement records off, or on, at any time in the console; keys created before 14 October 2026 have them off unless their owner switches them on. Exactly what we collect, why, where it is stored and for how long is set out in the Privacy Policy, which forms part of these terms.

13. Indemnification

This section applies only if you use our products in the course of a business. To the extent permitted by law, you agree to indemnify GOLProductions against claims by third parties, and the reasonable costs of defending them, to the extent they arise from:

  • your use of the service in breach of these terms;
  • your breach of any applicable law; or
  • your infringement of any third-party right, including through anything you submit to our services.

This indemnity is reduced to the extent a claim or loss was caused or contributed to by us, including by our negligence or breach of these terms. It does not apply to individuals using our products for personal, domestic or household purposes.

14. Limitation of liability

To the extent permitted by law, and subject always to section 8:

  • If you are a consumer and a service is of a kind ordinarily acquired for personal, domestic or household use, nothing in these terms limits our liability for failing to comply with a consumer guarantee.
  • Consumer guarantees for business services. Where a service is not of a kind ordinarily acquired for personal, domestic or household use, our liability for failing to comply with a consumer guarantee is limited to supplying the service again or paying the cost of having it supplied again, as section 64A of the Australian Consumer Law permits, unless it is not fair or reasonable for us to rely on this limit.
  • Other liability. For liability that is not under a consumer guarantee, our total liability in connection with a product is limited to the amount you paid us for that product in the 12 months before the claim. Where you have paid us nothing for a product, that amount is nil, except where the law does not allow it to be limited.
  • We are not liable for indirect or consequential loss, such as loss of profits, data, business opportunity or goodwill, except where that loss was reasonably foreseeable and is recoverable under the Australian Consumer Law, or the law otherwise does not allow it to be excluded.
  • We are not liable for failures caused by events outside our reasonable control (see section 16).
  • Nothing in these terms limits any liability that cannot lawfully be limited, including under the Australian Consumer Law, or excludes liability for death or personal injury caused by our negligence, or for fraud.

15. Ending your use of the service

  • Stopping use. You may stop using our services at any time. Your account and any unused credits remain intact and honoured indefinitely. You can ask us to delete your account and its data at any time (see the Privacy Policy).
  • Termination by us. We may suspend or terminate your account for breach of these terms, with notice where practicable. Where we terminate for reasons other than fraud or serious abuse, we will refund your unused credit balance to your original payment method.
  • Service discontinuation. If we permanently discontinue a product, we will provide at least 30 days' notice, and refund unused credits attributable to that product.

16. Force majeure

We are not liable for delays or failures caused by events beyond our reasonable control, including natural disasters, internet outages, infrastructure failures at our hosting providers, government actions, or pandemics. We will resume service as quickly as reasonably possible.

17. Changes to these terms

If we change these terms we will update the date at the top of this page. Material changes will be flagged in the console or by email. If a change materially disadvantages you, you may, before or within 30 days after it takes effect, stop using the affected product and ask us to refund unused credits for that product. Otherwise, continuing to use the service after the effective date means you accept the updated terms. Changes never apply retroactively to credits you already bought: those keep the terms they were bought under, or better.

18. Governing law and disputes

These terms are governed by the laws of Western Australia. Any dispute arising under these terms will be subject to the exclusive jurisdiction of the courts of Western Australia, without limiting your right to bring claims under the Australian Consumer Law in any court that has jurisdiction.

19. General

  • Entire agreement. These terms, the Privacy Policy, and any product-specific terms displayed at the time of purchase constitute the entire agreement between you and GOLProductions.
  • Severability. If any provision of these terms is found unenforceable, the rest remain in full effect.
  • Waiver. Failure to enforce any provision is not a waiver of our right to enforce it later.
  • Assignment. You may not transfer your account or these terms without our written consent. We may assign our rights under these terms in connection with a merger, acquisition, or sale of all or substantially all of our assets, provided the assignee honours existing credit balances.
  • No agency. Nothing in these terms creates a partnership, joint venture, or agency relationship between you and GOLProductions.
  • Independence and trademarks. Not affiliated with, endorsed by, or sponsored by Anthropic. Claude and Claude Code are trademarks of Anthropic, PBC. Cursor, Gemini, Codex, Windsurf, Devin and GitHub Copilot are trademarks of their respective owners. They are named only to say which tools Check works with.
