Use dataPublic Data Content (the free, non-commercial open access service): "all usage of Public Data Content is limited to internal purposes unless prior written consent is received from Synoptic", a map of it for a non-commercial purpose needs prior written consent and attribution to Synoptic on the website, "in the event that Synoptic discovers that Public Data Content is being used for any commercial purpose without its prior written consent, Synoptic reserves the right to immediately terminate the Client's access". Restricted Data Content (data from private sources and from value-add services such as Advanced Quality Control): "the Client may use any Restricted Data Content in its original form in any internal Client Offering", for an external-facing Client Offering, "Client may post summary statistics, summary plots, summary maps and similar summary items in published or electronic form, so long as the Restricted Data Content cannot be decompiled, reverse engineered, or otherwise extracted from Client's Derivative Works", "Client shall not have the right to redistribute the Restricted Data Content (either real-time or archive) without the prior written approval of Synoptic, such approval to be given or withheld in Synoptic's sole discretion". Both: "Client agrees that it will not use Data Content in any way that competes with Synoptic or is harmful to its business" and "will not engage in any extension or redistribution of the Data Access Service or Data Content to third parties in a manner that would be reasonably expected to cannibalize the sales or business or business of Synoptic without first obtaining the prior written consent of Synoptic", "Client shall not, and shall not assist or permit any third party to: (i) copy, modify, translate or create Derivative Works of any part of the Data Access Service, (ii) disassemble, decompile or in any other way reverse engineer any portion of the Data Access Service [...], or (iii) use Confidential Information (defined in Section 5.2) of Synoptic or take any other action to develop products or services competitive with the Data Access Service during the Term of this Agreement and within two years after its termination", the Data Content "is not designed or licensed for use in connection with securities trading, commodities trading, event contracts, gambling, or other speculative activities involving risk of capital". In return, Attachment A defines the attribution for a page, tool or app using the data beyond the Client's internal use: "Data Aggregated by Synoptic" (or similar words) where "Synoptic" hyperlinks to synopticdata.com, and "A Client with Non-Commercial and Basic Commercial usage is required to report annual usage statistics to Synoptic". Open Access Program: "All Open Access participants are asked to credit Synoptic Data in any published output from their research. This is a condition of the program", eligible uses are student research projects, faculty-led or on-campus research and non-commercial educational coursework.
