On this page, you can select or look up your country/region to find the corresponding official service hotline and email address of Huawei Digital Power, and reach out to us through these contact details.
We will make every effort to respond within a reasonable period upon receiving a request to access your data. This period will not exceed two months and may be extended if necessary, depending on the number of requests and their complexity. If the request period is to be extended, we will notify the data subject of the situation and reason for delay. In the event of any conflict between this section and local laws/regulations, the local laws/regulations shall prevail.
