DMCA Notice and Takedown Policy
CalcSummit respects intellectual property rights and complies with the Digital Millennium Copyright Act (DMCA), 17 U.S.C. § 512.

1. Overview
The DMCA provides a process for copyright owners to request removal of infringing content from websites (a “takedown”) and for content owners whose material was removed in error to request restoration (a “counter-notification”). Complying with these procedures gives CalcSummit safe harbor protection under 17 U.S.C. § 512(c). We take copyright seriously in both directions: protecting our own original content and respecting the copyright of others.
