TSE-Assistant

Terms of Service

Last updated: 1 October 2026

1. The service and the parties

TSE-Assistant is operated by TSE IT SOLUTIONS LIMITED, a company registered in England and Wales (number 15419504), registered office 25 Waterfield Way, Clipstone Village, Mansfield, NG21 9FD, VAT number GB476282561 ("we", "us"). We provide developer tools installed on your machines, a company dashboard, and Sofia, an AI assistant available in the installed app, in the dashboard, in Microsoft Teams and in Slack, for Microsoft Dynamics 365 Finance & Operations (together, "the Service"). Contact: support@tse-assistant.com.

Acceptance. You accept these Terms, and our Privacy Notice applies, when you tick the box at sign-up or checkout, or when you install the agent. We record which version you accepted and when. If you accept on behalf of a company, you confirm that you may bind it, and "you" means the company.

2. Accounts, eligibility and business use

The Service is for business use. By creating an account you confirm that you use it in the course of your trade, business or profession, or on behalf of the organisation you represent, and that you are authorised to work on the Dynamics 365 environments you connect it to. You must give accurate account information and keep your credentials, activation codes and registration tokens confidential. Company plans are administered by the company's admins, who are responsible for seat assignments, for the switches on the Configuration tab and for what their seats do with the Service.

3. Plans, trials and billing

Individual plans start with a 16-day free trial; no payment method is needed to start. After the trial the account drops to the free capped tier unless a paid plan is bought. Individual plans are billed monthly.

Company plans start with a 30-day free trial and are billed monthly or annually. Adding or removing seats mid-period is prorated by our payment provider.

Sofia credit (company plans) is a prepaid allowance for using Sofia on TSE's LLM. Each consultant seat brings a one-time $5 and each super-user seat $3 of credit, and the company may top up. Usage is metered at the model provider's own price for the model and region we use, including the provider's lower price for cached input, with nothing added; the current prices are on the Pricing page, each exactly as the provider charges us. A top-up adds Paddle's fee (5 % + $0.50) so the whole amount reaches your credit — $5 of credit costs $5.79, $25 costs $26.85 — plus VAT where it applies. Credit does not expire while the subscription is active, has no cash value, and unused credit is refundable as the Refund Policy says.

Storage (company plans). 1 GB of storage is included with every company plan - the published indexes and Sofia's conversations, memories and documents together. More comes in +2 GB storage packs at $2/month or $20/year, billed with the subscription. Above the allowance Sofia keeps answering, and only saving a new document waits until storage is added or data deleted.

Renewal, cancellation and prices. Paid subscriptions renew automatically until cancelled; cancelling stops future renewals, and paid features stay active until the end of the paid period. Prices may change with at least 30 days' notice. Plan and seat prices include VAT where it applies; top-ups add it.

Paddle. Our order process is conducted by our online reseller Paddle.com Market Ltd. Paddle is the merchant of record for all our orders and handles payment, invoices, tax, refunds and chargebacks; Paddle's buyer terms also apply to your purchase.

4. Your content and environments

Your source code, metadata, label texts, environment data and the content you give Sofia remain yours. The Service processes them as the Security & Data Handling page describes: most on your own machines; the published index and Sofia's conversations, memories and documents on our service, for your account only. You represent that you hold valid licences for Microsoft Dynamics 365 Finance & Operations and any other software in each environment you connect, and that you may let the Service process content from those environments, including Microsoft's label text generated from them. You are responsible for reviewing changes the tools propose before applying them: the Service is a development aid, not a replacement for your review, testing and deployment processes.

4a. AI output

The tools and Sofia produce output with the help of AI models. Output can be incomplete or wrong. Review it before you rely on it or apply a change; you decide what is applied. Output is not legal, tax, accounting or other professional advice.

4b. Data protection

Where we process personal data on behalf of a company account, our Data Processing Agreement forms part of these Terms and prevails for that processing. Our Privacy Notice says what we collect and why.

5. AI model processing and third-party AI services

We do not train or host our own large language model. AI features use either an AI provider you configure — your own API key, or GitHub Copilot, Cursor or Claude in your IDE — under the terms you hold with that provider, or TSE's LLM. TSE's LLM is a model service we provide through Microsoft Azure OpenAI (UK South) and, when your admin allows it, OpenAI (United States), and meter against your Sofia credit; those providers act as our sub-processors under section 4b and keep what the Privacy Notice says they keep. Sofia in the dashboard, in Teams and in Slack never reads source code.

For your own providers, you are responsible for choosing an account tier whose terms permit processing your code and any Microsoft-licensed code you work with — for example GitHub Copilot Business or Enterprise, or Azure OpenAI in your own tenant — and for your own data-governance obligations. We make no representation about, and accept no liability for, the data-retention, data-use or model-training practices of a provider you configure yourself.

6. Acceptable use

You may not: share, resell or circumvent licences, seats or capability gates; reverse engineer the Service except where the law permits; use the Service to violate third-party rights or applicable law; or attempt to disrupt the Service or other customers. We may suspend accounts that breach these Terms, with notice where practicable.

7. Intellectual property

We retain all rights in the Service, including the agent, the web service, Sofia and the bundled guidance content. Code, documents and other output generated in your environment or for your account with the tools and Sofia belong to you (or your organisation or client, under your own agreements).

8. Warranty disclaimer

The Service is provided "as is" and "as available", without warranties of any kind, express or implied, including fitness for a particular purpose and non-infringement, to the extent the law allows. Development environments are complex; we do not warrant that the Service is error-free or that generated code is correct — review and test before shipping.

9. Limitation of liability

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

Subject to that: we are not liable for indirect or consequential loss, or for loss of profits, revenue, business, data or goodwill, arising from use of the Service; and our total liability to you under or in connection with these Terms, in each 12-month period, is limited to the amounts you paid for the Service in the 12 months before the event giving rise to the claim. For our obligations under section 4b and the Data Processing Agreement, the cap is twice that amount.

10. Termination and your data at the end

You may stop using the Service at any time and ask us to close your account. We may suspend the Service for non-payment after notice, and terminate or suspend access for material breach of these Terms. When an account closes, you can ask for an export of your company's content during the next 90 days; after 90 days we delete it, except what the law requires us to keep. Sections 4, 4b, 7, 8, 9 and 12 survive termination.

11. Changes and governing law

We may update these Terms. We give at least 30 days' notice of material changes by e-mail to the account owner; if you do not accept them you may cancel before they apply, and we refund any period paid for and not used. Other changes are posted here with a revised date. These Terms are governed by the laws of England and Wales, and the courts of England and Wales have exclusive jurisdiction.

12. General

• Entire agreement. These Terms, the Privacy Notice, the Refund Policy, the Data Processing Agreement and the order you place with Paddle are the whole agreement between us about the Service, and replace any earlier understanding. Neither of us relies on a statement not set out in them, but nothing limits liability for fraud.
• Confidentiality. Each of us keeps the other's confidential information confidential, uses it only for the Service, and discloses it only to people who need it and are bound to keep it confidential, or where the law requires. Your content is your confidential information.
• Assignment and subcontracting. You may not transfer these Terms without our consent, which we will not unreasonably withhold. We may transfer them to a successor of our business on notice, and may use subcontractors (our sub-processors are listed on the sub-processors page); we remain responsible for them.
• Events beyond our control. Neither of us is liable for a failure caused by events beyond our reasonable control, but you may cancel if such an event stops the Service for more than 30 days.
• Third parties. No one other than you and us has any right to enforce these Terms (Contracts (Rights of Third Parties) Act 1999).
• Severability. If a court finds part of these Terms unenforceable, the rest stands.
• Notices. We write to the account owner's e-mail address; you write to support@tse-assistant.com or to the registered office above.
• Waiver. Not enforcing a term is not a waiver of it.
