Introduction

This SketchAPI License Agreement ("Agreement") is entered into by and between Customer and Sketch.IO, Inc., a Delaware Corporation located at 11177 SE Mystery Springs Ct, Clackamas, OR 97015 USA. All capitalized terms used in this Agreement and the attached Exhibits and Addenda shall be defined terms in the Agreement or in Exhibits attached hereto.

This Agreement governs use of the SketchAPI application programming interface (together with any documentation, updates, revisions, and substitutions, as well as any copies made by or for Customer, referred to in this agreement as the "SketchAPI"). Sketch.IO may condition delivery to Customer of future updates, revisions and substitutions upon acceptance of revisions to this Agreement.

Please note that Sketch.IO does not provide warranties for the SketchAPI. Sketch.IO provides maintenance and support for the SketchAPI during this Agreement's Initial Period and, if applicable, any subsequent Renewal Period(s). The contract also limits Sketch.IO's liability. These terms are in sections 8 and 9 and should be read carefully.
