Chrome Browser: Managed by the Organization on a Personal Computer

"If you have Microsoft Windows, Apple macOS, or Linux devices that are no longer being used in your organization, you might decide to repurpose and distribute them for personal use. Or, some users might purchase a second-hand Windows or macOS device, where Chrome browser was previously managed by an administrator in a school, company, or other group. 

If devices are not properly reset, an administrator might still manage Chrome browser. Before you repurpose a device, stop managing or delete the Chrome browser." Reference
