Lenovo takes the utmost responsibility when handling customer data, both domestically and abroad. Upon submitting your device for trade-in, all integral components such as the hard disk drive and memory will be stripped from the device, wiped clean of its original content, and destroyed in accordance with international data security standards. Furthermore, Lenovo will never keep nor transfer any of your personal data. All computers will go through the Data Erasure process. This service guarantees complete data erasure before shipment and is applicable to most devices over three years old.
