To the extent that Customer handles or otherwise has access to Personal Data (as that term is defined in Regulation (EU) 2016/679, generally known as the General Data Protection Regulation or GDPR), and that Whois API is a Processor of that Personal Data for Customer (with Customer as Controller):

  • (i) Customer agrees to execute a separate data processing addendum with Whois API which governs such Processing of Personal Data. Failure to adhere to the foregoing shall be a material breach of these terms.
  • (ii) A copy of these terms (the “GDPR Policy”) can be requested by emailing [email protected].  To the extent that the GDPR Policy conflicts with other terms in this Agreement, including the Privacy Policy, the GDPR Policy will control.

28.6 Personal Data License Grant

To the extent that Whois API is a processor of personal data (or otherwise manipulates or handles personal data) on behalf of Customer, Customer hereby grants to Whois API during the term of the Agreement, an irrevocable, perpetual, nonexclusive, royalty-free, and fully paid, worldwide, transferable, sublicensable license to the personal data. To the extent that an agreement between Whois API and any of its third-party providers requires Whois API to grant a license in said personal data to such third-party provider, the scope of the license set forth in the foregoing sentence shall be deemed to include the rights necessary to enable Whois API to grant such license.


28.7 CCPA Compliance

To the extent any Data or Parsed Data includes ‘personal information’ of California consumers (as defined under the California Consumer Privacy Act, CCPA), the parties acknowledge that Whois API is acting as a Service Provider for Customer. Whois API does not sell personal information provided through the Services, as ‘sell’ is defined in the CCPA. Customer warrants that it will comply with all applicable requirements of the CCPA (and any similar data privacy laws) in its use of the Data and Services. This includes providing any necessary notices and obtaining any required consents from consumers for the collection and use of personal information. Customer shall not use the Data or Services in a manner that causes Whois API to be deemed to be ‘selling’ personal information under the CCPA. Whois API will collect, process, and disclose personal information solely for the purpose of providing the Services in accordance with this Agreement, which is intended to qualify as a business purpose under the CCPA.
