Environmental Responsibility
Since inception Del Rey has operated as a green company, committed to conserving energy and natural resources. Our office relies upon natural light supplemented with energy efficient LED lighting, and the air conditioner stays off all summer. We limit our consumption of supplies, and repurpose many products for secondary uses. What little office paper we use is 100% post-consumer recycled paper.

The HandyGraph Story
The idea for HandyGraph was born in 2000 when the founder's mom asked for help creating computerized graphs to put in her math tests. After researching teachers' needs and designing a practical solution, Del Rey introduced HandyGraph as an uncomplicated graphing program. Since then HandyGraph has been enjoyed by thousands of math teachers and others all over the world. We regularly hear positive comments about HandyGraph and our customer service. Please send us your comments, questions, and suggestions.
