You are entitled to a free 90 trial of Pathagoras. No credit card is required to signed up for this trial. We recommend that you give Pathagoras a full workout during that 90 free trial period. (After all, it’s FREE!)
If you wish to purchase a license (either before, during or after a trial), and you decide that Pathagoras does not meet your needs, we will gladly refund your purchase price within 45 days of your purchase. . . . no questions asked. (Actually, we hope you will tell us why Pathagoras did not meet your needs, but that is not a condition of the refund.)
