As described in the Right to Limit Processing of Sensitive Personal Information section above, Costco does not process sensitive personal information in a manner that would be subject to that right. Costco also does not use personal information for automated decision making in a manner that is subject to the CCPA. As a result, we do not offer opt out of sensitive personal information processing, access to automated decision making information, or opt out for automated decision making.

HEALTH INFORMATION

When you engage with our pharmacies, optical, or hearing aid departments ("Health Care Centers"), we may collect and process Protected Health Information relating to you. Please see our Notice of Privacy Practices: Health Care Centers for a description of how we use and protect Protected Health Information.

Some state laws provide additional protections for personal information that identifies a past, present, or future physical or mental health status. This information is called Consumer Health Data. Please see our Consumer Health Data Privacy Notice for more information about how we collect and use Consumer Health Data, and your rights under applicable state laws.

AUTOMATED LICENSE PLATE RECOGNITION USAGE AND POLICY

We use Automated License Plate Recognition (ALPR) technology to collect information relating to vehicles present on or near some Costco facilities. We use this information to detect, prevent, investigate, report, and address incidents or illegal activities occurring in or around our facilities, to maintain security for our employees, vendors, members, and other visitors, for loss prevention purposes, and to measure and mitigate traffic flow on our properties, at gas pumps, and at car washes.

Costco restricts access to ALPR technology and ALPR information to only those Costco personnel with a need-to-know such information for their job requirements, such as senior management for the warehouse and region where the technology is in use, and our loss prevention and security personnel. These personnel receive training in data security and the sensitivity of ALPR information. Costco’s use of ALPR technology is overseen by Costco Corporate Purchasing, and the Director for Warehouse Operations.

ALPR information is subject to Costco’s access control processes and procedures. ALPR information is password protected, encrypted in transit and storage, and not used for purposes other than those disclosed in this Privacy Notice. Costco takes reasonable measures to ensure accuracy and integrity of the ALPR information it collects, including maintaining access controls and access logs. When using this information in connection with the investigation of an incident, Costco considers all available information, including information from other systems.

Costco’s use of ALPR is reviewed through our privacy assessment process at least every two years. ALPR Information is stored for approximately 180 days before it is permanently deleted, unless we need to retain the information for compliance with applicable law, investigation of specific incidents, upon request of law enforcement, or other valid legal processes.

Costco may disclose ALPR Information when we believe doing so is necessary to:

Protect the rights or property of ourselves or others, including detecting, investigating, and reporting suspicious activities to law enforcement;
Comply with applicable law or respond to legal process requests, including from law enforcement or other government agencies; or
Protect our Costco companies, our property and inventory, our shoppers, members, employees, or the public.

When ALPR Information is necessary for one of the above purposes, Costco uses reasonable safeguards, including encryption, to secure the transfer of ALPR information. Costco does not sell ALPR Information to third parties.

COSTCO EMPLOYEES, JOB APPLICANTS, AND OTHER BUSINESS CONTACTS

If you are a current or former Costco employee, contractor, vendor, other business contact, we will process personal information relating to your employment or business relationship in accordance with Costco Employee Privacy Notice. If you are a job applicant, Costco will process your personal information in accordance with the Costco Applicant Privacy Notice.

SECURITY OF PERSONAL INFORMATION

We take what we believe to be reasonable and appropriate steps to help protect personal information from unauthorized access, use, disclosure, alteration, and destruction. Unfortunately, no data transmission or storage system can be guaranteed to be 100% secure, and therefore we are unable to guarantee the security of your personal information.

CHANGES TO THIS PRIVACY NOTICE

We will update this Privacy Notice when necessary to reflect changes in our Services, how we use personal information, or the applicable law. When we post changes to this Privacy Notice, we will revise the "Last Updated" date at the top of the Privacy Notice. If we make material changes to the Privacy Notice, we will provide notice or obtain consent regarding such changes as may be required by law.
