Terms of Service

End User Licence Agreement and Terms of Service

Version 1.8 • Effective date: 16 June 2026 • Last updated: 24 June 2026

These Terms of Service (“Terms”) are a binding agreement between you (“you”, the “User”) and Circuitry, operated by John Wylie (“Circuitry”, “we”, “us”). They govern your access to and use of the Circuitry software, applications, websites, APIs and related services (the “Service”). Read them carefully. If you do not agree, do not use the Service.

1. Acceptance of these Terms

By creating an account, clicking “I agree”, subscribing, or otherwise accessing or using the Service, you confirm you have read, understood and agree to be bound by these Terms and the policies they reference, including our Privacy Policy and the acceptable-use rules in clause 7.

If you accept on behalf of an organisation (for example an agency, employer or client engagement), you represent that you have authority to bind it, and “you” means that organisation.

Electronic communications. You consent to receive communications and notices from us electronically (by email or in-product), and you agree that electronic communications satisfy any legal requirement that a communication be in writing.

We record the version of these Terms you accepted and the date and time of acceptance, which you agree is evidence of your agreement (see clause 32).

2. Definitions

“Service” means the Circuitry platform, including its design studio, code editor, interactive notebook, workflow and automation tools, MCP server, APIs, applications, websites and documentation.

“Your Content” means data, files, code, designs, prompts, text or other material you upload to, create within, or submit to the Service.

“Output” means material the Service generates from Your Content or your instructions.

“API” means our application programming interfaces and the MCP server, including any keys, tokens and endpoints.

“Intellectual Property Rights” means copyright, database rights, patents, trade marks, design rights, rights in confidential information and all other intellectual property rights worldwide, registered or not.

“Consumer” means an individual using the Service wholly or mainly outside their trade, business, craft or profession.

3. Eligibility and accounts

The Service is a private workspace for creating your own content — such as code, designs, notebooks and documents — and is suitable for use in education by students and teachers. It is not a social network or a content-sharing or publishing platform.

Who may use it. If you are an adult, you may create and use an account. If you are below the age of majority where you live, you may use the Service under the supervision of a parent, guardian, teacher or school who agrees to these Terms on your behalf and provides any consent required by law. A school or teacher may set up and supervise access for their students for educational use.

Children. Where the Service is used by a child, the supervising parent, guardian, teacher or school is responsible for that use and for giving or obtaining any parental or school consent required under applicable children’s-privacy laws (for example the UK Age Appropriate Design Code, the UK GDPR, and the U.S. Children’s Online Privacy Protection Act). We do not knowingly collect more personal data from a child than is needed to provide the Service. See our Privacy Policy for how we handle children’s data.

You are responsible for the accuracy of your account information, for keeping credentials secure, and for all activity under your account. Notify us promptly of any unauthorised use.

4. Licence to use Circuitry

Grant. Subject to these Terms and payment of applicable fees, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to access and use the Service for your personal or business purposes, including to create Output.

Commercial and client use. Unless your plan states otherwise, you may use the Service in your business and to produce Output for your own clients. This grants your clients no rights in the Service itself.

Run-time dependencies. Where Output requires the Service to function, you must either export it into a standalone form or ensure the relevant end user holds their own licence to the Service.

Restrictions. Except as the law allows or we permit in writing, you must not: copy, modify, distribute, sell, rent, sub-licence or commercially exploit the Service itself; reverse engineer, decompile or disassemble it (save where that restriction is prohibited by law); remove proprietary notices; use it to build a competing product or for unauthorised benchmarking; or use the Service, or any output, data, schemas, prompts, model behaviour or observations derived from your access to it, to train, fine-tune or distil any machine-learning or AI model, or otherwise to develop a product or service that competes with the Service.

5. Subscription plans, fees and billing

The Service is offered on free and paid plans; features, limits and price are shown at purchase. Paid plans are charged monthly or annually in the currency displayed (e.g. USD).

Plan inclusions and allowances. Paid plans include periodic allowances — for example AI credits and a number of cloud-hosted workflow or automation runs per billing cycle — as shown at purchase. These allowances refresh each cycle, do not roll over unless we state otherwise, have no cash value and are not redeemable for money. We may set, meter and change plan inclusions, allowances and the way usage is measured and priced going forward; for a material reduction to a paid plan’s core allowance we will give reasonable notice as set out in clause 22, and price changes are handled under this clause 5.

Auto-renewal. Paid Subscriptions renew automatically at the then-current price unless cancelled before renewal. We give reasonable notice of price changes.

Cancellation. You may cancel any time in account settings; cancellation takes effect at the end of the current period.

Taxes. Fees exclude taxes unless stated; you are responsible for applicable VAT/sales taxes except taxes on our income.

Refunds. Except where required by law (including clause 27) or expressly stated, fees are non-refundable.

Failed payment. We may suspend or downgrade access if a payment fails.

6. Free trials, free tier and beta features

We may offer free trials or a free tier and may change or withdraw them at any time. A paid plan may begin automatically at the end of a trial if you provided payment details and did not cancel; this will be made clear at sign-up.

Beta features. Features labelled beta, preview or experimental are provided “as is”, may change or be removed at any time, and may be less reliable; liability for them is excluded to the fullest extent permitted by law.

7. Acceptable use

You must not use the Service to break the law; infringe Intellectual Property Rights or privacy; upload malicious code; gain unauthorised access to systems; harass or harm others; generate unlawful, deceptive or harmful content; or place an unreasonable load on the Service.

No automated access or scraping. You must not access or interact with the Service by automated means — including bots, crawlers, scrapers, headless browsers or screen-capture tooling — except through interfaces or APIs we provide for that purpose, nor extract, harvest, index or compile data, content, interface designs or Output from the Service to build a dataset, index, archive or derivative service.

You are responsible for ensuring Your Content and your use comply with all laws and third-party rights. We may investigate suspected breaches and remove content or suspend accounts that breach this clause.

8. Fair use, resource limits and anti-abuse

Some features consume computing resources (for example notebook execution and distributed workflow runs). We may set and enforce reasonable usage limits, rate limits and fair-use thresholds, and may throttle, queue or suspend activity that is excessive, automated-abusive, or that threatens the stability, security or cost-integrity of the Service.

You must not circumvent usage limits, share accounts to exceed them, or use the Service to mine cryptocurrency or run unrelated bulk compute. We may charge for excess usage where your plan provides for it.

9. API and MCP access

If we make the API or MCP server available, your use is subject to these Terms and any published API documentation, limits and policies. You are responsible for the security of your API keys and tokens and for all activity under them.

You must not exceed published rate limits, resell or sub-licence API access, use the API to replicate or compete with the Service, or scrape or harvest data except as expressly permitted.

Changes and deprecation. We may modify, version or deprecate the API on reasonable notice where practicable. We are not liable for changes you have not adopted.

10. Your Content

Ownership. You retain all ownership of Your Content. We claim no ownership of it.

Licence to us. You grant us a worldwide, non-exclusive, royalty-free licence to host, store, copy, transmit, display (to you and to people you authorise) and process Your Content solely to provide, secure, maintain and improve the Service, and as set out in clause 11 and our Privacy Policy. This licence exists only so that we can run the Service for you; it does not permit us to use Your Content for our own purposes.

Confidentiality of Your Content. Your Content is private and confidential, and is your confidential information. We will not sell, publish, rent, or share or disclose Your Content to any third party, except: (a) to the extent necessary to provide the Service to you (for example, transmitting inputs to the AI model providers, plugins or integrations you choose to use, or making content available to people you choose to share or collaborate with); (b) with your permission; or (c) where we are required to do so by law or valid legal process.

Access by our personnel. Our personnel will not access the contents of Your Content (such as your workflows, files, code or designs) except where reasonably necessary to operate, secure or troubleshoot the Service, to prevent fraud, abuse or a security or legal risk, to comply with law, or to provide support or assistance you have requested. Where we view a specific document such as a workflow to help you, we do so only with your request or agreement.

Storage and backups. Where the Service includes cloud storage, we store and maintain Your Content as part of providing the Service and take reasonable technical and organisational measures to keep it safe and available. We cannot, however, guarantee against all loss, corruption or unavailability, and the Service is not intended to be your sole or archival backup. You must have all rights necessary to submit Your Content, and we recommend you keep your own copies of anything important or irreplaceable.

11. Use of data; analytics; and AI training

Service data. We collect and use technical and usage data (such as logs, device and performance data) to operate, secure, analyse and improve the Service.

Aggregated and de-identified data. We may create and use aggregated or de-identified data that does not identify you or any individual for any lawful business purpose, including analytics and improving our products.

AI model training. We do not use Your Content to train, fine-tune or develop generative AI models — that is not our business. If we ever offer a feature that learns from your use, it will be optional and we will describe it in the Privacy Policy and in-product settings before it applies to you.

12. Output and Deliverables

As between you and us, you own the Output you create using the Service, subject to your compliance with these Terms and payment of applicable fees.

Owning Output gives you no ownership of, or rights in, the Service used to create it — just as owning a document created in a word processor gives no rights in the word processor.

You are responsible for reviewing Output before relying on or distributing it, including Output produced for clients.

13. AI features

The Service includes AI-assisted features and may use third-party AI model providers to generate Output. Use of those features may also be subject to the providers’ terms, and you authorise us to transmit relevant inputs to them to provide the features.

No warranty on AI Output. AI Output may be inaccurate, incomplete, biased or unsuitable, similar Output may be generated for others, and it is not professional advice. You must independently verify AI Output and are responsible for how you use it.

Your inputs. You must not submit inputs you are not entitled to use, and must ensure your use of AI Output complies with law and third-party rights.

14. Third-party services and integrations

The Service may integrate with or link to third-party products, plugins, MCP-compatible assistants and services that we do not control and are not responsible for; your use of them is governed by their own terms and is at your risk.

15. Open-source components

The Service includes open-source software licensed under its own terms. Nothing in these Terms limits your rights, or adds obligations, under those open-source licences with respect to the open-source components themselves. A list of components and licences is available on request or in the Service.

16. Intellectual property

The Service and all Intellectual Property Rights in it are and remain owned solely and exclusively by us (or our licensors). These Terms grant you a licence only; they do not transfer any ownership of the Service to you, and you acquire no rights in the Service except the limited licence in clause 4.

“Circuitry”, our logos and brand features are our trade marks; you may not use them without our prior written consent.

Third-party names, logos and trade marks shown in the Service — for example to label an integration, connection or service — are the property of their respective owners and are used only to identify those products and services (nominative fair use). Their display does not imply any affiliation with, or sponsorship or endorsement by, their owners, and grants you no rights in those marks.

17. Feedback

If you give us suggestions or feedback, you grant us a perpetual, irrevocable, worldwide, royalty-free right to use them for any purpose without obligation to you, and any resulting improvement to the Service belongs to us.

18. Copyright complaints and repeat infringers

We respect Intellectual Property Rights and respond to valid notices of alleged infringement. If you believe content on the Service infringes your rights, send a notice to support [at] circuitry.dev including: identification of the work; identification and location of the allegedly infringing material; your contact details; a statement of good-faith belief that the use is unauthorised; a statement that the notice is accurate; and your signature (where applicable, in the form required by the U.S. Digital Millennium Copyright Act).

We may remove or disable access to allegedly infringing material, may provide a counter-notice procedure, and will terminate the accounts of repeat infringers in appropriate circumstances.

19. Privacy and data protection

We process personal data in accordance with our Privacy Policy and applicable law, including the UK GDPR and the Data Protection Act 2018. The Privacy Policy forms part of these Terms.

Where we process personal data on your behalf as a processor, a data processing addendum applies on request and forms part of these Terms.

20. Confidentiality

Non-public information about the Service (including non-public features, pricing, security details, and the design, structure, schemas, APIs and internal interfaces of the Service that you observe through your use of it) is our confidential information; you must not disclose it, or use it other than to use the Service as permitted, except as these Terms allow or the law requires.

Confidentiality runs both ways. We treat Your Content as your confidential information and protect it as set out in clause 10. Each party will use at least reasonable care to protect the other’s confidential information and will not use it except as permitted by these Terms.

21. Export control and sanctions

You must comply with all applicable export control and sanctions laws, including those of the United Kingdom, the European Union and the United States.

You represent that you are not located in, and are not a national or resident of, a country or territory subject to comprehensive sanctions, and that you are not on any restricted-party or sanctions list. You must not use, export or re-export the Service in breach of those laws, or for any prohibited end use.

22. Service availability and changes

We aim to keep the Service available but do not guarantee uninterrupted or error-free operation. We may carry out maintenance and may modify, suspend or discontinue parts of the Service. Where a change materially reduces a core paid feature, we will give reasonable notice and, where required, a pro-rata refund.

23. Term, suspension and termination

Term. These Terms apply while you have an account or use the Service.

By you. You may stop using the Service and close your account at any time.

By us. We may suspend or terminate access if you materially breach these Terms (without remedy within a reasonable time where the breach can be remedied), if required by law, or to protect the Service or others. For paid plans we will not terminate for convenience during a paid period, except as set out here.

Immediate suspension. We may suspend access immediately and without notice where we reasonably believe there is a security, legal or fraud risk, or a risk to the Service or others; we will restore access promptly once the risk is resolved where appropriate.

Effect. On termination your licence ends and you must stop using the Service. Output already exported into standalone form may continue to be used. We may delete Your Content after a reasonable period — export anything you wish to keep beforehand. Clauses that by nature should survive (including 10–13, 16–17, 24–26, 30–31) survive termination.

24. Disclaimers and warranties

The Service is provided “as is” and “as available”. To the fullest extent permitted by law we exclude all implied warranties and conditions, including fitness for a particular purpose and that the Service will be uninterrupted, secure or error-free.

25. Limitation of liability

Nothing limits liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be limited.

Subject to 25.1, to the fullest extent permitted by law we are not liable for loss of profits, revenue, business, goodwill or anticipated savings; loss of or damage to data; or any indirect or consequential loss.

Subject to 25.1, our total aggregate liability arising out of or in connection with these Terms is limited to the greater of (a) the fees you paid us in the 12 months before the event giving rise to the claim, or (b) $100.

Limitation period. Except where the law provides otherwise (including for Consumers), any claim must be brought within one year of the date the cause of action arose, failing which it is permanently barred.

26. Your indemnification of us

If you use the Service as a business (not as a Consumer), you will indemnify us against claims, losses and reasonable costs arising from your breach of these Terms, your misuse of the Service, or Your Content or Output infringing a third party’s rights.

27. Your rights if you are a Consumer

If you are a Consumer, you have statutory rights that these Terms do not affect, including under the Consumer Rights Act 2015 and the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013.

Cancellation of digital content. Where the Service is supplied as digital content you normally have a 14-day right to cancel. By starting to use the Service immediately you may be asked to acknowledge that you lose that cancellation right once supply has begun, to the extent permitted by law.

The arbitration and class-waiver provisions in clause 30 do not apply to you to the extent they cannot be enforced against Consumers where you live.

28. App stores (Apple and Google)

If you obtain the Service through a third-party app store, you also agree to that store’s usage rules, and the following apply between you and us as well as, where required, with the store as a third-party beneficiary.

Apple App Store. These Terms are between you and Circuitry only, not Apple. Apple has no obligation to provide maintenance or support for the application. Apple is not responsible for any product warranties, product or IP claims, or legal/consumer claims relating to the application; Circuitry is solely responsible to the extent required by law. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. You confirm you are not in a US-embargoed or restricted country and are not on a US restricted-party list.

Google Play. You also agree to the Google Play Terms of Service. Circuitry, not Google, is responsible for the application and its support.

29. Changes to these Terms

We may update these Terms. For material changes we will give reasonable notice (by email or in-product) before they take effect. Continued use after a change takes effect means you accept the updated Terms. Each version has a version number and effective date, and we keep a record of which version you accepted.

30. Dispute resolution; arbitration and class-action waiver

Informal resolution. Please contact us first; most disputes can be resolved informally, and you agree to try for 30 days before starting formal proceedings.

Governing law. These Terms and any dispute are governed by the law of England and Wales. Subject to the remainder of this clause, the courts of England and Wales have exclusive jurisdiction.

Arbitration (United States users). If you are resident in the United States, you and we agree that any dispute will be resolved by binding individual arbitration administered by JAMS under its rules, rather than in court, except that either party may bring qualifying claims in small-claims court. Judgment on the award may be entered in any court of competent jurisdiction.

Class-action waiver (United States users). To the extent permitted by law, US users and we each waive any right to bring or participate in a class, collective or representative action, and disputes will be arbitrated only on an individual basis.

Opt-out. You may opt out of clauses 30.3–30.4 by emailing support [at] circuitry.dev within 30 days of first accepting these Terms; opting out does not affect the rest of these Terms.

31. General

Assignment. You may not assign these Terms without our consent. We may assign them to an affiliate or in connection with a merger, acquisition, reorganisation or sale of assets (for example, a future corporate reorganisation).

Entire agreement. These Terms with the policies they reference are the entire agreement between you and us about the Service.

Severability. If any provision is unenforceable, the rest remains in effect.

No waiver. A failure to enforce a provision is not a waiver of it.

Force majeure. We are not liable for delays or failures caused by events beyond our reasonable control.

No partnership. Nothing in these Terms creates a partnership, agency or employment relationship between the parties.

Interpretation. Headings are for convenience only; “including” means “including without limitation”.

32. Record of acceptance and versioning

Acceptance is recorded electronically. For each acceptance we may record the account identifier, the version of these Terms accepted, the date and time of acceptance (UTC), and technical information such as IP address for security and evidential purposes.

You agree these records are admissible and are sufficient evidence of your acceptance of the identified version of these Terms.

33. How to contact us

Questions about these Terms: support [at] circuitry.dev.

By using the Service, you acknowledge that you have read and agree to these Terms.
