7. Your Rights
You can send us an email at supportoverseas@dahuatech.com to request exercising your rights in relation to your personal data. You may also object to or request us to restrict the processing of your personal data. If we process your personal data based on consent, you may withdraw your consent at any time by contacting us at supportoverseas@dahuatech.com. A summary of your legal rights is set out below
Request access to your personal data (commonly known as a "data subject access request"). This enables you to receive a copy of the personal data we hold about you and to check that we are lawfully processing it.
Request correction of the personal data that we hold about you. This enables you to have any incomplete or inaccurate data we hold about you corrected, though we may need to verify the accuracy of the new data you provide to us.
Request erasure of your personal data. This enables you to ask us to delete or remove personal data by entering into the page of Me-> Personal Info->Delete Account on the Product or contact us at supportoverseas@dahuatech.com, where there is no good reason for us continuing to process it. You also have the right to ask us to delete or remove your personal data where you have successfully exercised your right to object to processing (see below), where we may have processed your data unlawfully or where we are required to erase your personal data to comply with local law. However, for specific legal reasons, such as it is mandatory for us to retain your personal data as required by laws, we may not be able to comply with your request of erasure but we will notify you at the time of your request in such circumstance, if applicable.
Object to processing of your personal data where we are relying on a legitimate interest (or those of a third party) and there is something about your particular situation which makes you want to object to processing on this ground as you feel it impacts on your fundamental rights and freedoms. You also have the right to object where we are processing your personal data for direct marketing purposes. In some cases, we may demonstrate that we have compelling legitimate grounds to process your personal data which override your rights and freedoms.
Request restriction of processing of your personal data. This enables you to ask us to suspend the processing of your personal data in the following scenarios: (a) if you want us to establish the data's accuracy; (b) where our use of the data is unlawful but you do not want us to erase it; (c) where you need us to hold the data even if we no longer require it as you need it to establish, exercise or defend legal claims; or (d) you have objected to our use of your data but we need to verify whether we have overriding legitimate grounds to use it.
Request the transfer of your personal data to you or to a third party. We will provide to you, or a third party you have chosen, your personal data in a structured, commonly used, machine-readable format. Note that this right only applies to automated data which you initially provided consent for us to use or where we used the data to perform a contract with you.
Withdraw consent at any time where we are relying on consent to process your personal data. However, this will not affect the lawfulness of any processing carried out before you withdraw your consent. If you withdraw your consent, we may not be able to provide certain services to you. We will advise you if this is the case at the time you withdraw your consent.
For security reasons, we will take steps to authenticate your identity before providing access to your personal data. You also have the right to lodge a complaint with the relevant Data Protection Authority.

We keep this Privacy Policy under review and may modify this Privacy Policy from time to time.
