2) Video and Audio Data
The App allows you to access and view surveillance data captured or recorded by
Compatible Hardware (as defined in the Terms of Use). “Surveillance Data” comprises
(1) video (and in some cases audio) recordings or live feeds or streams and still
photographic images; (2) readings or data from physical or virtual sensors (to the extent
offered by or included with Compatible Hardware and supported by the App), including
motion detection sensors, event sensors, temperature sensors, window/door sensors,
passive infrared sensors, water sensors, carbon dioxide sensors and ambient light
sensors.
3) Processing in compliance with applicable laws
Apart from the detail activities specified above, we may process your personal data which
is permitted or required by applicable laws:
Processing is necessary for the performance of a contract or in order to take steps at
your request prior to entering into a contract.
Processing is necessary for compliance with a legal obligation.
Processing is necessary in order to protect the vital interests of data subject or of
another natural person.
Processing is necessary for the performance of a task carried out in the public
interest or in the exercise of official authority vested.
Processing is necessary for the purposes of the legitimate interests pursued by us or
by a third party, except where such interests are overridden by the interests or
fundamental rights and freedoms of data subject, in particular where the data subject
is a child.
Other lawfulness of processing as specified in applicable laws.
2. How We Share, Assign and Disclose Your Personal Data
We may share, assign or disclose your personal data in the following circumstances. You
shall be fully responsible and liable for the personal data you collect or obtain from other
resources or from other data subjects.
1) Trusted third parties:
We may share, assign or disclose your personal data with certain trusted third parties
such as our subsidiaries and affiliates; or contractors, service providers, and other third
parties in order to perform contract with you or provide you services. The third parties are
bound by contractual obligations to keep your personal data confidential and use it only
for the purposes instructed by us or permitted by applicable laws.
2) Required or permitted by applicable laws:
We may share, assign or disclose your personal data when it is permitted by applicable
laws, or to comply with applicable legal requirements such as court order, legal process,
including to respond to any government or regulatory authority’s request or for
investigations (e.g. disclosure to prevent crime or fraud, or to comply with a court order or
legislation).
3) Merger, acquisition or bankruptcy:
We may share, assign or disclose your personal data where there is a merger,
acquisition or bankruptcy procedure. We will require the successor who holds your
personal data to continue to perform the obligations in accordance with this Policy.
4) Public Interest:
We may share, assign or disclose your personal data for public interest purpose, such as
to deal with public health emergencies, or, in case of emergency, to protect the health of
natural persons and the safety of their property.
3. How We Protect and Retain Your Personal Data
1) Data security measures
We attach great importance to the security of your personal data. We have taken
appropriate physical, technical and management security measures to prevent your
personal data from accidental losses and from unauthorized access, use, alteration and
disclosure. For instance, we use encryption technology to improve the security of
personal data and trusted protection mechanisms to prevent personal data from being
maliciously attacked.
2) The retention of personal data
We will retain your personal data for no longer than it is necessary for the purposes
stated in this Policy, unless otherwise extending the retention period is required or
permitted by law. To determine the appropriate retention period for personal data, we
may consider the amount, nature and sensitivity of the personal data, the potential risk
from unauthorized use or disclosure of your personal data, the purposes for which we
process your personal data and whether we can achieve those purposes through other
channels. If you want to learn more about the retention period of your personal data, you
may directly contact us at supportoverseas@dahuatech.com.
4. How We Protect Children’s Personal Data
Our Apps are not designed for children under 16 years of age, or equivalent minimum
age in the relevant jurisdiction (refer to “Child” or “Children” below). If we become aware
of any personal data related to Children, we will delete that Children’s personal data
unilaterally, unless otherwise the processing is permitted by applicable law, explicitly
consented by the Children’s parents or guardians, or deemed necessary for the
protection of the Children.
5. International Transfers
Since we have affiliates around the world to offer you services and we may store your
personal data on our servers located in different countries, including United States,
Germany, and Singapore. In light of this, your personal data may be transferred outside
the region or country where you use the App or Service, which may have different legal
rules and level of protection on personal data. In such circumstances, we will take
necessary measures to ensure that your personal data is processed in conformity with
the applicable laws, including obtaining your consent to the cross-border transfer of your
personal data, signing standard contractual clauses approved by the EU Commission
when necessary, and taking appropriate technical security measures to safeguard your
personal data.
6. 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【Account – Delete Account】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 Apps or 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.
7. Changes to Privacy Policy
We keep this Privacy Policy under review and may modify this Privacy Policy from time to
time. If we make major changes to this Policy, we will notify you through different
channels, for example, by posting a pop-out notice on the App to notify the major
changes.
8. How to Contact Us
If you have any questions or comment on this Privacy Policy or our privacy practices,
