1. About Notis

Notis is a software-as-a-service (SaaS) platform designed to assist contractors and commercial managers in administering NEC4 Engineering and Construction Contracts. The Service is provided by Ryburn Commercial Services Ltd, a company incorporated in England and Wales with company registration number 13511979, whose registered office is at 2 Stones Drive, Ripponden, HX6 4NY.

2. Definitions

In these Terms:

3. Subscription and Access

3.1 Eligibility and Business Use Warranty

The Service is available to businesses, organisations, and sole traders operating entirely in a professional capacity. By subscribing to or using the Service, you warrant and represent that:

If any of the above warranties prove untrue, we reserve the right to terminate your access to the Service immediately.

3.2 Subscription Plans

Access to the Service is provided on a subscription basis. Current plans and pricing are set out on our pricing page at notis.solutions/pricing. We reserve the right to change pricing with not less than 30 days' notice to existing Subscribers.

3.3 Free Trial

We offer a free trial period for new Subscribers, currently 30 days, as described on our pricing page at notis.solutions/pricing. No payment card is required to start a free trial.

During the trial period, you will have full access to the Service. We will send you reminder emails before your trial ends, informing you of the remaining time and inviting you to add a payment method to continue using the Service.

If you do not add a payment method before the trial period ends, your access to the Service will be paused. No charge will be made unless and until you actively add a payment method and begin a paid subscription. Your Contract Data is retained during this paused period in accordance with Section 8, so you can resume access at any time by subscribing.

We reserve the right to change the length or terms of any future free trial offer with reasonable notice.

3.4 Payment

Subscriptions are billed in advance on a monthly or annual basis depending on your chosen plan, as displayed at the point of purchase. Payment is processed via Stripe. By providing payment details, you authorise us to charge your payment method on a recurring basis at the applicable subscription rate until your subscription is cancelled. All prices are exclusive of VAT where applicable.

3.5 Cancellation

You may cancel your subscription at any time via your account settings or by contacting us at hello@notis.solutions. Cancellation takes effect at the end of your current billing period. We do not provide refunds for unused subscription periods except where required by law.

3.6 Suspension and Termination

We may suspend or terminate your access to the Service if you breach these Terms, fail to pay subscription fees, or if we reasonably believe your use of the Service creates legal or reputational risk. We will give reasonable notice where practicable before suspension or termination.

5. AI Features, Intellectual Property in Outputs, and Important Disclaimer

5.1 Nature of AI Features

Notis includes features that use artificial intelligence to assist with the drafting of notices, quotations, and other contractual communications. These features are designed to assist experienced commercial managers and quantity surveyors, not to replace professional judgement.

5.2 Ownership of AI-Generated Outputs

To the extent that any AI-Generated Outputs produced by the Service are capable of protection under intellectual property law (including under section 9(3) of the Copyright, Designs and Patents Act 1988 as computer-generated works), Ryburn Commercial Services Ltd hereby assigns all right, title, and interest in such AI-Generated Outputs to the Subscriber, subject to the Subscriber's continued compliance with these Terms. This assignment takes effect automatically upon generation of the relevant output.

For the avoidance of doubt, you own the notices, quotations, and other contractual documents generated for you by the Service, and may use, copy, and distribute them as required in connection with your contracts.

5.3 Review Before Issue

All AI-generated content must be reviewed by a competent person before it is issued under any contract. The Service includes a structured review step before notices are issued for this purpose. You are solely responsible for the accuracy, completeness, and appropriateness of any notice or communication issued using the Service.

5.4 Not Legal or Professional Advice

Nothing in the Service constitutes legal advice, quantity surveying advice, or any other form of professional advice. The Service is a contract administration tool. For advice specific to your contractual position, you should consult a qualified NEC4 practitioner, solicitor, or other appropriate professional.

5.5 No Liability for Contractual Outcomes

We accept no liability for any contractual outcome, loss of entitlement, financial loss, or other consequence arising from your use of or reliance on the Service, including any AI-Generated Outputs. Time-barred notifications, missed deadlines, and incorrect quotations remain the responsibility of the User.

5.6 AI Processing by Third Party

When you use AI Features, the content you submit (including contract descriptions and event details) is processed by Anthropic's Claude API. Anthropic acts as a data processor under our instructions and is bound by a data processing agreement with us. Anthropic does not use data submitted via the API to train its models. By using AI Features, you consent to this processing. You should not submit special category personal data or confidential commercial information belonging to third parties beyond what is necessary to generate the relevant notice.

6. Contract Data and Intellectual Property

6.1 Your Data

You retain ownership of all Contract Data you enter into the Service. We do not claim any intellectual property rights in your Contract Data or in AI-Generated Outputs (which are assigned to you under Section 5.2).

6.2 Licence to Us

By entering Contract Data into the Service, you grant us a limited, non-exclusive licence to store, process, and display that data solely for the purpose of providing the Service to you.

6.3 Our Intellectual Property

The Service, including all software, design, content, AI prompts, and methodologies, is owned by or licensed to Ryburn Commercial Services Ltd. Nothing in these Terms transfers ownership of our intellectual property to you.

6.4 Feedback

If you provide feedback, suggestions, or ideas about the Service, you grant us a perpetual, royalty-free licence to use that feedback without restriction or compensation.

7. Data Processing

In providing the Service, we act in two capacities:

Our obligations as a data processor in respect of Contract Data are set out in our Data Processing Addendum, which forms part of these Terms and is available at notis.solutions/dpa. By using the Service, you agree to the terms of the Data Processing Addendum.

Our full Privacy Policy, which governs how we handle personal data in our capacity as a Data Controller, is available at notis.solutions/privacy.

8. Data Portability and Retention

You may export your Contract Data at any time using the export features within the Service. Upon termination of your subscription, we will retain your data for 90 days during which you may request an export. After 90 days, your data will be securely deleted. We will notify you before deletion occurs.

9. Availability and Service Levels

We aim to provide the Service with high availability but do not guarantee uninterrupted access. We may carry out planned maintenance from time to time and will endeavour to give advance notice. We accept no liability for losses arising from Service unavailability, whether planned or unplanned.

10. Limitation of Liability

To the maximum extent permitted by law, Ryburn Commercial Services Ltd's total aggregate liability to you in connection with the Service — whether arising in contract, tort (including negligence), breach of statutory duty, under any indemnity, or otherwise — shall not exceed the total subscription fees paid by you in the 12 months immediately preceding the event giving rise to the claim, or the sum of £1,000 (whichever is higher).

We shall not be liable for any indirect, consequential, special, or punitive loss including loss of profit, loss of revenue, loss of contract, loss of data, loss of anticipated savings, or loss of contractual entitlement under any NEC4 or other construction contract.

Nothing in these Terms limits liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, or any other liability that cannot be excluded or limited by law.

11. Changes to the Service and These Terms

We may update these Terms from time to time. We will notify you of material changes by email or via an in-app notification at least 30 days before the changes take effect. Your continued use of the Service after that date constitutes acceptance of the updated Terms. For material structural changes — such as changes to the liability provisions or data usage — we may additionally require you to confirm acceptance via an in-app prompt on your next login.

We may also modify, suspend, or discontinue features of the Service. Where a modification materially reduces the functionality of the Service, we will notify you and you may cancel your subscription without penalty.

12. Governing Law and Disputes

These Terms are governed by and construed in accordance with the laws of England and Wales. Any dispute arising from or in connection with these Terms shall be subject to the exclusive jurisdiction of the courts of England and Wales.

Before initiating formal proceedings, we encourage you to contact us at hello@notis.solutions to attempt to resolve any dispute informally.

13. General

If any provision of these Terms is found to be unenforceable, the remaining provisions shall continue in full force and effect. Our failure to enforce any right or provision shall not constitute a waiver of that right. These Terms constitute the entire agreement between us in relation to the Service and supersede any prior agreements.

A person who is not a party to these Terms shall not have any rights under the Contracts (Rights of Third Parties) Act 1999 to enforce any term of this agreement.

Neither party shall be in breach of these Terms nor liable for delay in performing, or failure to perform, any of its obligations under this agreement if such delay or failure results from events, circumstances, or causes beyond its reasonable control, including without limitation acts of God, pandemic, war, cyberattack, failure of third party infrastructure, or action by a government or public authority.
