Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and ContingenciesOur platform and associated products are subject to various restrictions under U.S. export control and sanctions laws and regulations, including the U.S. Department of Commerce’s Export Administration Regulations (“EAR”) and various economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Controls (“OFAC”). The U.S. export control laws and U.S. economic sanctions laws include restrictions or prohibitions on the sale or supply of certain products and services to U.S. embargoed or sanctioned countries, governments, persons, and entities, and also require authorization for the export of certain encryption items. In addition, various countries regulate the import of certain encryption technology, including through import permitting and licensing requirements and have enacted or could enact laws that could limit our ability to distribute our platform or could limit our hosts’ ability to implement our platform in those countries.Although we take precautions to prevent our platform and associated products from being accessed or used in violation of such laws, we have inadvertently allowed our platform and associated products to be accessed or used by some customers in apparent violation of U.S. economic sanction laws. In addition, we may have inadvertently made our software products available to some customers, including users in embargoed or sanctioned countries, in apparent violation of the EAR. As a result, we have submitted initial and final voluntary self-disclosures concerning potential violations of U.S. sanctions and export control laws and regulations to the OFAC and the U.S. Department of Commerce’s Bureau of Industry and Security (“BIS”). In June 2019, OFAC and BIS issued us warning letters as their final enforcement responses to these potential violations, but no fines or penalties were assessed. If we are found to be in violation of U.S. economic sanctions or export control laws in the future, it could result in fines and penalties.
