Terms of Service

1. Introduction

1.1 Who we are The Website and Service are provided by TYTN LIMITED (trading as Doubleword), a company incorporated in England and Wales (company number 13353288) with registered office at 73 Cornhill, London, EC3V 3QQ (“TYTN”, “Doubleword”, “we”, “us”, “our”).

‍1.2 What these Terms cover:

These terms (“Terms”) apply to:

• our websites, including doubleword.ai and any successor URLs (the “Website”); and
• our hosted APIs, software, documentation and dashboards (including app.doubleword.ai and any successor URLs) (together, the “Service”).

We may also provide training, migration, or other services if we agree this with you in writing (“Professional Services”).

1.3 Business use only. The Service is for business use only. By using the Service, you confirm you are acting for a business (not as a consumer) and you have authority to accept these Terms for that business.

1.4 Acceptance and start date. By using the Website or Service, or clicking “I Agree” (or similar), you agree to these Terms and confirm you have read our Privacy Policy. These Terms start when you first do any of those things (the “Effective Date”).

1.5 Changes to these Terms. We may amend these Terms from time to time. If we make a material change, we will take reasonable steps to give you notice (for example, by email, in-product notice, or by posting an updated version on the Website). The amended Terms will apply from the date stated in the notice (or if no date is stated, from the date we publish them). Continued use of the Service after that date constitutes acceptance of the amended Terms.

1.6 Other agreements. If you have a separate written agreement with us (for example an MSA or Order Form), that agreement continues to apply for its scope. These Terms do not supersede it unless the separate agreement expressly says they do. If there is a conflict between these Terms and a separate written agreement, the separate written agreement will prevail to the extent of the conflict and only for the relevant subject matter.

2. Services

‍

2.1 Services Subject to these Terms, we grant you a non-exclusive, non-transferable right during the Term to access and use the Service for your business purposes, including to develop, operate, and provide your own products and services to your end users that integrate the Service.

The Service may include application programming interfaces, access keys or tokens, software development tools, documentation, and other features we make available from time to time (together, the “APIs”). We may provide the Service, including any models, endpoints, features, documentation, or supported integrations, on a basis that may change over time. We may modify, suspend, or discontinue any part of the Service, including imposing or changing rate limits, usage limits, or other technical limits. Where reasonably practicable, we will take reasonable steps to give you advance notice of any material adverse change.

2.2 No service level commitment unless agreed. We do not guarantee that the Service will be uninterrupted, error-free, or available at all times. Any service levels, support commitments, or uptime commitments will apply only if they are expressly set out in an Order Form or other written agreement signed by both parties.

2.3 Security. We will implement appropriate technical and organisational measures designed to help protect the security, confidentiality and integrity of your Content (as defined in these Terms), and to reduce the risk of unauthorised access to it. You acknowledge that no method of transmission or storage is completely secure.

2.4 Monitoring and enforcement. We may monitor and analyse use of the Service to:

• operate, secure, maintain, and improve the Service;
• prevent abuse, fraud, and security incidents;
• verify compliance with these Terms; and
• support billing, usage reporting, and capacity planning,

In each case in accordance with applicable law and our Privacy Policy.

3. Accounts and Access

To access the Service, you may need to create an account and obtain credentials such as API keys, access tokens, or similar security credentials (“Credentials”). You must provide accurate and complete information when creating an account and keep your account information up to date.

You are responsible for:

• all activity that occurs under your account and Credentials (including by your employees, contractors, and other authorised users); and
• keeping your Credentials confidential and secure.

You must promptly notify us if you become aware of any unauthorised access to, or use of, your account or Credentials, or any suspected security incident relating to the Service.

We may suspend or restrict access to the Service where we reasonably believe your account or Credentials have been compromised, or where suspension is reasonably necessary to protect the Service, you, other users, or third parties.

4. Your Responsibilities

You will:

• use the Service in accordance with these Terms and all applicable laws and regulations;
• ensure that anyone you permit to use the Service under your account complies with these Terms;
• be responsible for obtaining and maintaining the equipment, software, and internet connectivity needed to access the Service; and
• use commercially reasonable efforts to prevent unauthorised access to or use of the Service.

5. Privacy and personal data

If you provide personal data to us in connection with the Service (for example, names, email addresses, or billing information), we will handle it as described in our Privacy Policy.

Where the Service is used to process personal data on your behalf (for example, personal data included in inputs or outputs), the parties will comply with applicable data protection law.

If your use of the Service requires a data processing addendum (DPA) under applicable data protection law, our DPA will apply and is available on request.

6. Third-Party Models and terms

The Service may provide access to models, software, weights, libraries, or other components provided by third parties (“Third-Party Models”). Third-Party Models may be subject to separate terms, licences, or acceptable use requirements set by the relevant third party (“Third-Party Terms”).

You are responsible for complying with any applicable Third-Party Terms. If there is a conflict between these Terms and any Third-Party Terms, the Third-Party Terms will prevail, but only to the extent of the conflict and only for the relevant Third-Party Model.

We do not endorse any Third-Party Model and we do not make any warranties about Third-Party Models. Third-Party Models are provided “as is” and “as available” and may be modified, withdrawn, or made unavailable by the relevant third party.

To the extent permitted by law, we are not responsible for the content, accuracy, output quality, availability, security, or performance of Third-Party Models, or for any viruses or other harmful code originating from Third-Party Models.

7. Your Content

7.1 Content. When you use the Service, you (or your authorised users) may submit content such as text, images, audio, video, code, documents, or prompts (together, “Your Content”). The Service may generate results based on Your Content (the “Output”).

You are responsible for Your Content and your use of any Output, including ensuring that Your Content and your use of Output comply with these Terms and applicable law.

You represent and warrant that you have all rights, licences, consents, and permissions needed to provide Your Content to us and to allow us to use it as described in these Terms.

7.2 Ownership. As between you and us, you retain all rights in Your Content. As between you and us, and to the extent permitted by law, we assign to you any rights we may have in the Output that is generated for you from your Content. This does not affect our ownership of the Service, the APIs, the underlying software, or any models, weights, or other components we make available as part of the Service. Output may not be unique and the Service may generate similar or identical output for other users.

7.3 Licence to provide the service. You grant us a non-exclusive, worldwide licence to host, copy, process, transmit, and otherwise use Your Content and Output only as necessary to:

• provide, operate, maintain, and secure the Service;
• prevent or address technical issues, abuse, fraud, or security incidents;
• comply with applicable law and enforce these Terms; and
• generate and use aggregated or de-identified analytics and metrics relating to use of the Service (“Usage Data”) to operate, maintain, and improve the Service, provided that Usage Data does not identify you or any individual.

7.4 Improving the Service and training (opt-in). By default, we do not use Your Content or Output directly to train models except to the extent needed to provide and operate the Service for you.

If you choose to opt in (for example via account settings or another written method we provide), you grant us an additional licence to use Your Content and Output directly to develop, improve, and support the Service, which may include training models. Any such use will be as described in the applicable settings and our data usage materials in force at the time. If you later withdraw your opt-in, the change will apply going forward and will not affect any use of Your Content or Output that occurred while your opt-in was in effect.

8. Acceptable Use and Restrictions

1. interfere with, damage, or disrupt the Service, our systems, or other users’ use of the Service;

For clarity, automated access to the APIs is permitted, subject to usage limits, rate limits, and these Terms;

9. Fees

9.1 Pricing and credits. The Service is paid for using pre-paid credits (“Credits”). The price for Credits and any applicable usage rates are set out on our pricing page (as updated from time to time).

Unless we agree otherwise in an Order Form, we will deduct Credits for usage when a job is initialised (or, where applicable, as otherwise described in the Service).

9.2 Billing information and payment method. You must provide complete and accurate billing information and keep it up to date, including a valid and authorised payment method. You authorise us (and our third-party payment processors) to charge your payment method for all fees and charges due under these Terms.

9.3 Auto-replenishment. If you enable auto-replenishment, you authorise us (and our payment processors) to automatically purchase additional Credits by charging your payment method when your Credit balance falls below the replenishment threshold you set (or as otherwise configured in your account settings). You can change or disable auto-replenishment in the Service or by contacting Support.

‍9.4 Changes to fees. We may introduce new products or services, change the fees or pricing for existing products or services, or discontinue any offering. Any fee change will take effect as set out on the pricing page or, where we provide you notice, from the start of your next billing cycle after that notice.

If we have agreed a fixed price or a specific term in an Order Form, that Order Form will govern for that product or service during the applicable term.

‍9.5 No refunds. Except where required by applicable law or expressly stated in an Order Form or where we terminate for convenience, all fees are non-refundable and payment obligations are non-cancellable. Unused Credits are non-refundable.

9.6 Late payment and suspension. If payment is overdue, we may suspend your access to the Service on notice. We may also charge interest on overdue amounts at the statutory rate under the Late Payment of Commercial Debts (Interest) Act 1998, together with reasonable costs of recovery, where applicable.

9.7 Taxes. All amounts payable under these Terms are exclusive of VAT and any other applicable taxes, duties, or similar governmental charges. You are responsible for paying all such charges, except for taxes based on our net income.

10. Intellectual Property

10.1 Our materials and the Service. We (and our licensors) own all right, title, and interest in and to the Website and the Service, including all software, APIs, documentation, trademarks, logos, and related technology, and all intellectual property rights in them (together, “Company IP”). Company IP does not include Third-Party Models, which are owned by their respective owners. Except for the rights expressly granted to you under these Terms, we reserve all rights in Company IP.

Subject to these Terms, we grant you a non-exclusive, non-transferable, non-sublicensable licence to access and use the Service and any documentation we make available to you, solely for your business purposes and in accordance with these Terms.

10.2 Your Content and Output. As between you and us, you retain all rights in Your Content. As between you and us, and to the extent permitted by law, we assign to you any rights we may have in the Output generated for you from Your Content. For clarity, your use of the Service and any Output does not grant you any ownership rights in Company IP or any underlying technology, models, or weights used to provide the Service.

10.3 Usage Data. We may collect and generate aggregated or de-identified technical and operational data relating to use of the Service (“Usage Data”). Usage Data excludes Your Content and personal data. We own Usage Data and may use Usage Data to operate, maintain, secure, and improve the Service, to develop new features or services, to monitor for abuse, and for analytics.

10.4 Feedback. If you provide suggestions, comments, ideas, or other feedback about the Service (“Feedback”), you grant us a worldwide, perpetual, irrevocable, royalty-free licence to use, reproduce, modify, create derivative works from, distribute, and otherwise exploit that Feedback without restriction or obligation to you.

11. Confidentiality

11.1 Confidential Information. The Service may include non-public, proprietary, or confidential information of Doubleword and/or other users (“Confidential Information”).

You must: (a) keep Confidential Information confidential and protect it using at least the same degree of care you use to protect your own confidential information of a similar nature, and in any event no less than a reasonable degree of care; (b) use Confidential Information only as necessary to exercise your rights and perform your obligations under these Terms; and (c) not disclose Confidential Information to any third party except to your employees, contractors, service providers, and professional advisers who need to know it for the permitted purpose and who are bound by confidentiality obligations at least as protective as those in this section.

13.3 Suspension or termination by us. We may suspend your access to the Service or terminate these Terms if: (a) you materially breach these Terms; (b) we reasonably determine that your use of the Service creates a credible risk of harm, security risk, or liability to us, the Service, other users, or any third party; or (c) we are required to do so by law or a regulator.

Where reasonably practicable, we will give you notice and a reasonable opportunity to remedy the breach before suspending or terminating.

15.1 Our IP indemnity. We will defend you against any claim brought by a third party alleging that your use of the Service (excluding Third-Party Models) in accordance with these Terms infringes that third party’s intellectual property rights (an “IP Claim”), and we will indemnify you for any amounts finally awarded against you by a court of competent jurisdiction or agreed in a settlement that we approve.

15.2 Process.

If we terminate under this clause, we will refund any prepaid fees or unused Credits you have paid for the terminated portion of the Service that you have not used as of the termination date.

15.6 Your indemnity. You will defend us against any claim brought by a third party arising out of: (a) Your Content; (b) your products or services (including how you use, provide, or market Output); or (c) your breach of these Terms or applicable law, and you will indemnify us for any amounts finally awarded against us by a court of competent jurisdiction or agreed in a settlement that you approve (such approval not to be unreasonably withheld or delayed).

18.5 Subcontracting. We may subcontract or delegate our obligations under these Terms.

18.6 Entire agreement.

18.8 No partnership. Nothing in this Agreement is intended to or shall operate to create a partnership between the parties, or authorise either party to act as agent for the other, and neither party shall have the authority to act in the name or on behalf of or otherwise to bind the other in any way (including, but not limited to, the making of any representation or warranty, the assumption of any obligation or liability and the exercise of any right or power).

‍18.12 Third party rights.
