The privacy policy lists all of the information Instacart collects and reserves the right to use or share that information when it wants to. What it collects depends on the services a customer uses.
A license plate number, for example, becomes an issue when a customer does curbside pickup. Health information becomes a potential issue if medical prescriptions are delivered, and if pharmacy deliveries are used, Instacart says it will retain, use and potentially share “your past, present or future physical or mental health or condition; the provision of health care to you; or your past, present, or future payment for the provision of health care.”
Though Instacart wrote that it will not disclose personal health information “without prior written consent,” it lists various exceptions, including the vague and broad “in connection with a business transaction or bankruptcy proceeding.”
