Some jobs may require access to your personal data on the device. The engineer will tell you if there is a risk of exposure to your personal data, but the data will never be copied to engineer’s personal device. If data transfer of any sort is required, that will be uploaded to an external device provided by the customer. If the customer does not have an external device, the data can be uploaded to any other source as directed by the customer. In such situations, the agreement made will be mentioned in the job sheet.
