Terms and Conditions

Last updated April 03, 2026

These Terms and Conditions ("Terms") govern the relationship between Lagrange Engineering SRL, a company registered in Romania under CUI 51196824, with its registered office at Str. Ioan Alexandru 20, Timisoara, Timis 300323, Romania ("Lagrange," "we," "us," or "our"), and you ("Client," "you," or "your") regarding the use of our website and the provision of our services.

By accessing our website or engaging our services, you agree to be bound by these Terms. If you do not agree with any part of these Terms, please do not use our website or services.

1. Services

Lagrange Engineering provides custom software development services, including but not limited to: AI & machine learning solutions, web application development, mobile application development, and technical consulting ("Services").

The specific scope, deliverables, timeline, and pricing for each project are defined in individual proposals or contracts ("Project Agreement") agreed upon by both parties. In case of any conflict between these Terms and a Project Agreement, the Project Agreement shall prevail.

2. Proposals and Acceptance

Proposals provided by Lagrange Engineering are valid for 30 (thirty) calendar days from the date of issuance, unless otherwise stated in the proposal.

A proposal is considered accepted when the Client provides written confirmation (including email) or makes the first payment as outlined in the proposal. Acceptance of a proposal constitutes agreement to the scope, timeline, pricing, and these Terms.

3. Payment Terms

Payment terms are specified in each Project Agreement. Unless otherwise agreed:

  • Invoices are due within 14 (fourteen) calendar days from the date of issuance.
  • All prices are stated in the currency specified in the Project Agreement and are exclusive of VAT, which will be added where applicable under Romanian law.
  • Late payments may incur a penalty of 0.1% per day of delay, in accordance with Romanian legislation on combating late payment (Law 72/2013).
  • Lagrange Engineering reserves the right to suspend work on a project if invoices remain unpaid for more than 30 (thirty) days beyond their due date.

4. Intellectual Property

Upon full payment of all amounts due under a Project Agreement:

  • The Client shall receive full ownership of all custom code, designs, and deliverables specifically created for the project ("Project IP").
  • Lagrange Engineering retains ownership of any pre-existing tools, libraries, frameworks, and general-purpose code ("Lagrange IP") used in the project. The Client is granted a non-exclusive, perpetual, royalty-free license to use Lagrange IP as part of the delivered project.
  • Third-party software and open-source components used in the project remain subject to their respective licenses.

Until full payment is received, all intellectual property rights in the deliverables remain with Lagrange Engineering.

5. Confidentiality

Both parties agree to keep confidential any proprietary information, trade secrets, technical data, business plans, or other sensitive information disclosed during the course of the engagement ("Confidential Information").

This obligation of confidentiality shall survive the termination of the engagement for a period of 2 (two) years, unless the information becomes publicly available through no fault of the receiving party.

Lagrange Engineering reserves the right to mention the Client's name and a general description of the project in its portfolio and marketing materials, unless the Client explicitly requests otherwise in writing.

6. Project Timeline and Delivery

Timelines provided in proposals and Project Agreements are good-faith estimates based on the information available at the time. They are not guaranteed deadlines unless explicitly stated as such.

Delays caused by the Client (including but not limited to: late feedback, delayed content or asset delivery, scope changes, or unavailability of key stakeholders) may result in a corresponding extension of the project timeline.

Lagrange Engineering will communicate proactively about any anticipated delays and work with the Client to find reasonable solutions.

7. Change Requests

Any changes to the agreed scope of work must be requested in writing and acknowledged by Lagrange Engineering. Changes may affect the project timeline and cost.

Lagrange Engineering will provide an estimate for the impact of the requested changes before proceeding. Work on change requests will only begin after written approval from the Client.

8. Warranties

Lagrange Engineering warrants that:

  • The Services will be performed in a professional and workmanlike manner, consistent with industry standards.
  • The deliverables will substantially conform to the specifications outlined in the Project Agreement for the warranty period defined in the respective Project Agreement or specifications document ("caiet de sarcini") ("Warranty Period"). If no warranty period is specified, a default of 30 (thirty) calendar days from delivery shall apply.
  • During the Warranty Period, Lagrange Engineering will correct any defects or bugs at no additional cost, provided the issues are caused by Lagrange Engineering's work and not by modifications made by the Client or third parties.

Beyond the Warranty Period, maintenance and support are available under separate agreements.

9. Limitation of Liability

To the maximum extent permitted by Romanian law:

  • Lagrange Engineering's total liability under any Project Agreement shall not exceed the total amounts paid by the Client under that specific agreement.
  • Lagrange Engineering shall not be liable for any indirect, incidental, consequential, or special damages, including but not limited to: loss of profits, loss of data, business interruption, or loss of business opportunities.
  • Lagrange Engineering shall not be liable for damages arising from the Client's misuse of the deliverables, modifications made by third parties, or failure to maintain adequate backups.

10. Termination

Either party may terminate a Project Agreement with 15 (fifteen) calendar days' written notice.

In the event of termination:

  • The Client shall pay for all work completed up to the date of termination, including any committed expenses.
  • Upon payment, the Client receives ownership of all deliverables completed up to the termination date.
  • Any advance payments for work not yet performed will be refunded, minus a reasonable amount for administrative costs and work-in-progress.

Either party may terminate immediately if the other party materially breaches these Terms or a Project Agreement and fails to remedy such breach within 15 (fifteen) calendar days of written notice.

11. Force Majeure

Neither party shall be liable for delays or failure to perform resulting from events beyond their reasonable control, including but not limited to: natural disasters, war, government actions, epidemics, internet or power outages, or other similar events ("Force Majeure").

The affected party must notify the other party promptly and take reasonable steps to mitigate the impact. If a Force Majeure event continues for more than 60 (sixty) days, either party may terminate the affected Project Agreement without penalty.

Any disputes arising from or in connection with these Terms or any Project Agreement shall first be attempted to be resolved amicably through direct negotiation. If no resolution is reached within 30 (thirty) calendar days, the dispute shall be submitted to the competent courts of Timisoara, Romania.

15. Amendments
