4. 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 cloud.huaxiao@wisualarm.com.

5. 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.

6. 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 China and Germany. 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.

For users in the EEA or UK, we ensure transfers are subject to Adequacy Decisions or the latest Standard Contractual Clauses (SCCs), supplemented by technical measures like encryption.

7. Your Rights

You can send us an email at cloud.huaxiao@wisualarm.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 cloud.huaxiao@wisualarm.com. A summary of your legal rights is set out below

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.
