Terms of Service

These Terms govern your use of Deadline Engine, a software product operated by Thesmios Ltd, company number 17150638, trading as Deadline Engine. References to “we”, “us”, and “our” mean Thesmios Ltd. References to “you” mean the person or organisation using Deadline Engine.

2. No solicitor-client relationship

Using Deadline Engine does not create a solicitor-client relationship between you and Thesmios Ltd, between you and Victor Humenhuk, or between you and any other person associated with Deadline Engine. We do not provide legal advice. We do not act as your legal representative. We owe you no fiduciary duty.

Communication with Deadline Engine support staff is not privileged. Information you submit to Deadline Engine in the course of using the calculator, such as trigger dates, party names, or court references, is processed under our Privacy Policy and is not protected by legal professional privilege.

3. Service description

Deadline Engine is a deterministic software calculator for UK legal deadlines. It covers procedural and regulatory frameworks encoded in the product. It provides calculated dates, citations, reminder tools, saved calculations, and calendar exports.

4. Eligibility and account security

You must be at least 18 years old and able to enter into a binding contract. You must provide accurate account information, keep your login credentials confidential, and tell us promptly if you suspect unauthorised access.

5. Fees, trial, and billing

Deadline Engine Pro is offered at £8.99 per month or £79.99 per year. A 7-day free trial is available to new subscribers. A payment card is required at checkout. You will not be charged during the trial. Unless you cancel before the trial ends, your subscription converts to a paid subscription on day 8. All fees are stated inclusive of VAT at the prevailing UK rate. We will issue VAT invoices on request for business customers.

Payments are processed by Stripe. We do not process or store card details. You may manage or cancel your subscription through the billing portal in your account.

6. Refunds and cancellation

You may cancel at any time. Cancellation normally takes effect at the end of the current billing period. We do not provide pro-rata refunds except where required by law. If you buy as a consumer, statutory cancellation rights may apply under the Consumer Contracts Regulations 2013.

7. Limitation of liability

To the fullest extent permitted by law:

(a) Our total aggregate liability to you in connection with your use of Deadline Engine, whether in contract, tort including negligence, breach of statutory duty, or otherwise, is limited to the greater of:

(i) the total amount of fees you have actually paid to us in the twelve months immediately before the event giving rise to the claim; and
(ii) one hundred pounds sterling (£100).

(b) We are not liable for any of the following types of loss, even if foreseeable, and even if we have been advised of the possibility of such loss:

• loss of profits;
• loss of business or business opportunity;
• loss of revenue;
• loss of anticipated savings;
• loss of goodwill or reputation;
• loss of clients or contracts;
• any indirect, special, or consequential loss;
• any loss arising from your failure to independently verify a calculation produced by Deadline Engine;
• any loss arising from a missed limitation period, missed procedural deadline, or missed filing deadline, where you have used Deadline Engine without independently verifying the calculation against the underlying rule;
• any loss arising from changes to procedural rules that occur after the software was last updated;
• any loss arising from your incorrect input of trigger dates, jurisdictions, or other parameters.

(c) The limitations in this clause apply to the maximum extent permitted by law. Nothing in this clause excludes or limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot lawfully be excluded under English law.

(d) You acknowledge that Deadline Engine is offered at a low price specifically because the liability cap is low. The price would be materially higher if we accepted broader liability. By accepting these Terms you acknowledge this allocation of risk is reasonable.

(e) Where Thesmios Ltd is the contracting party under these Terms, you agree that you will not bring any claim against any director, employee, or contractor of Thesmios Ltd in their personal capacity in respect of any matter arising under these Terms. Any claim must be brought against Thesmios Ltd as the contracting party.

8. Your warranties and indemnity

By using Deadline Engine, you warrant and represent that:

• You are a qualified legal professional, a paralegal working under the supervision of a qualified legal professional, a law student, an in-house counsel, or another person with sufficient training to understand procedural deadlines.
• You will independently verify every calculation produced by Deadline Engine before relying on it for any actual matter.
• You will not rely on Deadline Engine as your sole or primary source of deadline information for any matter where missing the deadline could cause loss.
• You will maintain your own diary, calendar, and case management records as a primary system, with Deadline Engine as a secondary cross-check only.
• You will not provide Deadline Engine output to a client without first independently verifying the calculation.
• You will not market Deadline Engine output as legal advice or as a substitute for legal advice.
• If you are a solicitor, barrister, paralegal, or other regulated legal professional, you warrant that you understand your professional obligations to maintain your own deadline tracking systems and that Deadline Engine is a tool you use at your own discretion and risk. You acknowledge that the duty to your client to meet procedural deadlines is yours, not ours, and that you cannot transfer that duty by relying on third-party software.
• You agree that if a claim is made against you by your client or by your professional indemnity insurer arising from a missed deadline, you will not bring a claim against Thesmios Ltd or Victor Humenhuk as a result of that missed deadline, except to the extent that we have engaged in fraud or wilful misconduct.

You agree to indemnify and hold harmless Thesmios Ltd, its directors, employees, and contractors against any claim, loss, damage, cost, or expense including legal fees arising from your breach of these warranties.

9. No warranty as to accuracy

Deadline Engine is provided “as is” and “as available”. To the fullest extent permitted by law, we make no warranties, express or implied, including but not limited to:

• that the calculations produced by Deadline Engine are accurate or complete;
• that the underlying rules encoded in the software are current or correctly interpreted;
• that Deadline Engine will be available without interruption;
• that Deadline Engine is free from defects or errors;
• that Deadline Engine is fit for any particular purpose, including your particular matter.

We make reasonable efforts to keep the rules current. We test our calculations extensively. We provide citations to source materials. None of this is a guarantee of correctness in any individual case. The duty to verify rests with you.

10. Intellectual property and permitted use

All intellectual property in Deadline Engine, including the calculation logic, interface, documentation, and generated templates, belongs to us or our licensors. We grant you a limited, non-exclusive, non-transferable licence to use Deadline Engine for your internal professional or educational use while your account is active.

11. Suspension and termination

We may suspend or terminate your account if you breach these Terms, misuse the service, fail to pay, or if suspension is required by law. On termination, access to paid features ends. Data retention is governed by the Privacy Policy.

12. Changes to these Terms

We may update these Terms from time to time. Material changes will be notified by email or in-app notice at least 14 days before they take effect. Continued use after the effective date constitutes acceptance. If you do not accept the changes, you must stop using Deadline Engine and may cancel your subscription.

13. Governing law and disputes

These Terms and any dispute or claim arising out of them are governed by the laws of England and Wales.

The courts of England and Wales have exclusive jurisdiction to hear and decide any dispute arising out of these Terms. By using Deadline Engine you submit to the exclusive jurisdiction of those courts.

Before commencing any court proceedings, you agree to attempt to resolve the dispute by sending a written notice to hello@deadlineengine.com setting out the nature of the dispute and the remedy you seek. We will respond within 14 days. If the dispute remains unresolved 30 days after our response, either party may commence proceedings.

14. Your acknowledgement

• You have read and understood these Terms.
• You understand Deadline Engine is a calculator, not legal advice.
• You understand the limitation of liability and consider it reasonable in light of the price.
