Compliance with the Law and Constant Improvement of Information Management
DISCO complies with all laws and regulations pertaining to the protection of personal information and is committed to the continuous improvement of its procedures for handling, managing, and protecting it.
Handling and Management: General Guidelines
1. DISCO establishes internal rules for handling Personal Information and makes known to its executives and all employees the proper procedures for handling, managing, and protecting it.
2. DISCO specifies clear purposes for using Personal Information and does not use it beyond the scope of these purposes without the permission of Information Providers. (For the purposes of use, see "Purpose of Use" below.)
3. DISCO establishes internal controls, including information security controls, to protect Personal Information from unauthorized access, unauthorized divulging, improper alteration, misplacement or loss, etc.
4. DISCO does not communicate Personal Information to third parties without the permission of Information Providers, except as directed by law or as necessary in subcontracting (see next number) or sharing of information with the group companies.
5. DISCO supplies Personal Information to subcontractors only within the scope of specified purposes of use. In doing so, DISCO confirms that Personal Information is being managed properly by those to whom it is conveyed.
Purposes of Use
DISCO employs Personal Information only for the sake of its Activities and within the scope of the following purposes. However, in the case that consent has been provided separately by the Information Provider, Personal Information may be used within the agreed scope of purpose. Furthermore, Personal Information is not used for the purpose of automated judgments (such as profiling) without the consent of the Information Provider.
Sharing Information with Group Companies
Based on the location or content of inquires or transactions, DISCO shares some Personal Information within DISCO Group companies as necessary to perform its Activities effectively throughout the world, keeping within the specified purposes of use. In sharing information with group companies, each group company has signed a standard agreement in accordance with the provisions in the General Data Protection Regulation (hereafter "GDPR").
* Some of the group companies are located outside of the European Economic Area (hereafter "EEA").

Period for Retaining Personal Information
The DISCO Group stores Personal information for the period necessary to achieve the specified purpose of use. Personal information is promptly deleted once the storage period has lapsed.
Selection by Information Provider
As a general rule, Personal Information is provided to the DISCO Group by the Information Provider with the consent of the Information Provider, and the Information Provider does not have an obligation to provide the Personal Information to the DISCO Group. However, if the Personal Information is not provided or is insufficient, we may not be able to provide the following services to the Information Provider, causing a disadvantage to the Information Provider.
Agreement and Rescinding Agreement with the Personal Information Protection Policy
The Information Provider agrees with the Personal Information Protection Policy, and the DISCO Group shall handle the Personal Information of the Information Provider in accordance with the applicable laws (including but not limited to the laws corresponding to the GDPR when it applies), this Personal Information Protection Policy, and the internal regulations of the DISCO Group. The Information Provider may rescind their agreement at any time by contacting any of the point of inquiries for Personal Information listed below.
In addition, even in the event that agreement is rescinded, it will not affect the validity to process Personal Information that was used before the agreement was rescinded. Furthermore, if the agreement is rescinded by the Information Provider, DISCO may not be able to provide the services listed in "Selection by Information Provider" to the Information Provider, causing a disadvantage to the Information Provider.
Disclosure, Correction, and Suspended Use of Personal Information, and Submitting an Objection
