Software terms of use


Access to the software products (hereinafter referred to as "Software Products") of ESI GROUP (hereinafter referred to as "ESI") is possible subject to compliance by the User (i.e. the person accessing the Software Product) with the present TERMS AND CONDITIONS OF USE (hereinafter referred to as "TCU").

You are advised to read the TCU each time you visit this website, as they may be amended at any time without notice.


Use of the Software Products, whether free of charge or requiring payment, implies the User's agreement to abide by the TCU.

Where the User has access to Software Products, the ESI Master Agreement or any specific contract ("Agreement") entered into between ESI and the User's company ("Company") to which the User has subscribed shall prevail over the TCU even in the event of contradiction.

The Software Products are intended for reasonable and normal use.


Access to Software Products is defined in the quotation drawn up between the User's company and ESI. The quotation ("Quotation") is the contractual document arising from the Agreement which individually designates the Software Product(s), the duration, the territory, the financial conditions and the specific conditions of use (including the type of license).

There are three license categories at ESI:

  • Commercial license: contractual authorization to use the Software Product, in the form of a readable object or machine only, for commercial purposes. Use of the Software Product is limited to the Company's own personnel or to external parties working on behalf of the Company, for its own projects or projects for its own customers.
  • Trial license: contractual authorization to use the Software Product, in object/machine-readable form only, for the purpose of evaluating the Software Product only. Use of the Software Product is limited to employees, with no right to use it for operational purposes. Trial licenses may under no circumstances exceed a duration of three months (with no possibility of renewal). No trial licenses are granted for controlled products (export control).
  • Non-commercial license: contractual authorization to use the Software Product limited to internal needs and not used for the benefit of third parties. Use of the Software Product is limited to the Company's personnel and, if the Company is an academic entity, to its students.
