Claresco Corporation respects individual privacy and values the confidence of its clients, their customers, our business partners and others. Not only do we strive to store Personal Information in a manner consistent with the laws of the countries in which we do business, but we also have a tradition of upholding the highest ethical standards in our business practices. Claresco Corporation is subject to the investigatory and enforcement policies of the Federal Trade Commission. This US-EU Privacy Shield Privacy Policy (Policy) sets forth the privacy principles Claresco Corporation follows with respect to transfers of Personal Information from the EEA to the United States.

Note: It must be emphasized that Claresco Corporation does not have control over the uses to which our clients may make of Personal Information disclosed to them.


The United States Department of Commerce and the European Commission have agreed on a set of data protection principles and frequently asked questions to enable U.S. companies to satisfy the requirement under European Union law that adequate protection be given to Personal Information transferred from the EEA to the United States (EU-US Privacy Shield). The EEA also has recognized the EU-US Privacy Shield as providing adequate data protection (Directive 95/46/EC ). Consistent with our commitment to protect personal privacy, Claresco Corporation adheres to the principles set forth in the EU-US Privacy Shield (EU-US Privacy Shield Principles).


This Policy applies to all Personal Information received by Claresco Corporation in the United States from the EEA, in any format, including electronic, paper or verbal.


For purposes of this Policy, the following definitions shall apply:

"Agent" means any third party that collects or uses Personal Information under the instructions of, and solely for, Claresco Corporation.

"Client" means any customer of Claresco Corporation, located in the EEA, for whom we host a website or enterprise management system on our servers in the United States.

Claresco Corporation does not collect Personal Information directly from individuals in the EEA. Where Claresco Corporation receives, stores, or processes Personal Information from our clients in the EEA, we will use and disclose such information in accordance with the notices provided by our clients, only if consistent with the EU-US Privacy Shield Principles, and the choices made by the individuals to whom such Personal Information relates. We will endeavor, as much as is practicable, to enable our clients to publish and follow the EU Data Protection Directive on their websites that we host.


Claresco Corporation will enable our clients to offer individuals the opportunity to choose (opt-out) whether their Personal Information is (a) to be disclosed to a third party, or (b) to be used for a purpose other than the purpose for which it was originally collected or subsequently authorized by the individual. Claresco Corporation will enable our clients to provide individuals with reasonable mechanisms to exercise their choices.


Claresco Corporation does not transfer data to third parties outside of its agents, except where Claresco Corporation receives written instructions from clients. Claresco Corporation will obtain assurances from its agents that they will safeguard Personal Information consistently with this Policy. Examples of appropriate assurances that may be provided by agents include: a contract obligating the agent to provide at least the same level of protection as is required by the relevant EU-US Privacy Shield Principles, being subject to EU Directive 95/46/EC (the EU Data Protection Directive), EU-US Privacy Shield certification by the agent, or being subject to another European Commission adequacy finding (e.g., companies located in Canada). Where Claresco Corporation has knowledge that an agent is using or disclosing Personal Information in a manner contrary to this Policy, Claresco Corporation will take reasonable steps to prevent or stop the use or disclosure. Claresco Corporation is liable for appropriate onward transfers of personal data to third parties who do not comply with the Privacy Shield principles. Claresco Corporation may disclose an individual's Personal Information as required and in response to a lawful request from public authorities.

In addition, Claresco Corporation will take reasonable steps to permit individuals to correct, amend, or delete information that is demonstrated to be inaccurate or incomplete. Many Sites that Claresco Corporation hosts provide a personal profile page that allows the user to review and/or modify their Personal Information. For Sites where no such page is provided, users may submit requests to Claresco directly, or via its Clients to request access and/or modification to, or deletion of, their Personal Information.


Claresco Corporation will conduct compliance audits of its relevant privacy practices to verify adherence to this Policy. Any employee that Claresco Corporation determines is in violation of this policy will be subject to disciplinary action up to and including termination of employment.
