Terms of use and licence

Last updated: 8 October 2026

These terms are an agreement between you (the person or company using EGS IS) and EGS InfraStudio (“EGS IS”, “we”). By installing or using the software, or by requesting a licence, you accept them.

Part A. The website

You may use this website to learn about EGS IS, download it and contact us. Do not try to break into it, overload it or send automated requests to its forms. Prices and features shown can change; the price that applies is the one we confirm in reply to your request.

Part B. Software licence (EULA)

1. The licence

EGS IS is licensed, not sold. A licence lets you use the modules and period named in your licence file, on the PC it was issued for. We keep all rights in the software, its code and its content.

2. Free trial

The 7-day trial licence is for evaluation, on the PC it was issued for. It is provided as is.

3. Paid licences

• A licence is valid for the period you bought, from the start date in the licence file.
• One licence is for one PC. To use EGS IS on more PCs, buy more seats.
• If you replace your PC, contact us and we move the licence.
• If a licence cannot be activated on the PC it was requested for and we cannot fix the problem, we refund it.

4. What you may not do

• Copy, share, sell or rent the software or a licence file.
• Change, reverse-engineer or decompile the software, or bypass the licence check or its clock protection, except where the law allows it.
• Remove our names or notices from the software.

5. Updates

While your licence is active you may install the updates we publish. Updates can add, change or remove features.

6. Engineering responsibility

EGS IS is a design aid. It does not replace the judgement of a qualified engineer. You are responsible for checking every result, drawing and quantity before you use it, and for meeting the codes and standards that apply to your project.

7. Warranty

We work hard to make EGS IS correct and reliable, and we fix the problems you report. Apart from that, and to the extent the law allows, the software is provided “as is”, without other warranties.

8. Liability

To the extent the law allows, we are not liable for indirect or consequential losses (such as lost profit, delays or lost data), and our total liability is limited to what you paid for the licence in the twelve months before the claim.

9. Ending the licence

The licence ends at the end of its period, or earlier if you break these terms. When it ends you must stop using the licensed modules. Your own project files remain yours.

10. Third-party software

EGS IS includes open-source components under their own licences; their notices are installed with the application. AutoCAD and Civil 3D are products of Autodesk; WaterGEMS is a product of Bentley Systems. EGS IS is not affiliated with or endorsed by them.

Part C. General

These terms are governed by the laws of the Arab Republic of Egypt, and the courts of Cairo have jurisdiction. If one part of these terms cannot be enforced, the rest still applies. We may update these terms; the version in force when you buy or renew a licence applies to that licence.
