We offer a supported 30-day product evaluation to commercial and academic users who wish to preview the features and capabilities of LEDA. Evaluation versions are provided to you in order to help you find out whether or not LEDA suits your needs, and to decide whether or not you may purchase one or more LEDA licenses after the evaluation.

LEDA has been developed and obtained by the investment of significant time, effort and expense, and LEDA is a valuable, special and unique asset of our company. Due to severe license misuses of our LEDA evaluation software, we by now wish to confirm the seriousness of your requests for an evaluation copy and hope that you understand and support this new policy of our company.

Thus, in order to receive a restricted evaluation version, we will ask you to

• Send us your name, email address, organization and your field of activity, and
• pay a 25 US$ or EURO 20 amount through Paypal to confirm your purchase intention. This amount will be credited against your order once you decide to purchase a regular LEDA license. Otherwise, it will be used to cover our administrational costs for your evaluation.

Step 1: Send us your contact information.

Step 2: Transfer US$ 25.00 or EURO 20.00 to us via PayPal.
