1. Information We Collect

WEST collects personal information that can be used to identify you directly or indirectly (“Personal Information”). Personal Information also includes anonymous information that is linked to information that can be used to identify you directly or indirectly. Personal Information does not include information that has been irreversibly anonymized or aggregated so that it can no longer enable us, whether in combination with other information or otherwise, to identify you.

Below is a description of the types of Personal Information we may collect and how we use it.

1.1 Information You Voluntarily Provide

We collect Personal Information that you and others intentionally and voluntarily provide when using this Website or our services. For example, we collect Personal Information when you subscribe to our emails, subscribe to Cloud Services, request technical support, attend webinars, or contact us with questions.

1.2 Information from Your Browser, Device, or Products

We collect information that your web browser or mobile device sends to us automatically, or, if applicable, that products send to us when used with one of our Cloud Services. This information typically includes your IP address, the IP address of your product, the GPS location of your product, the name of your operating system, the name and version of your browser, and usage information. The information we receive may depend on your browser or device settings and information you define personally within cloud data streams. The information we receive from your web browser and devices is not personally identifiable on its own. We generally use this information in aggregate to help us improve this Website and make it more compatible with the technologies used by our visitors. However, we may combine it with other information in an attempt to identify you, or we may combine it with information that does identify you. We may also review our server logs for security purposes (e.g., to detect intrusions into our network) and we may share our server logs, which contain visitors’ IP addresses, with appropriate investigative authorities who may use that information to track and identify you.

1.3 Your Location

Using GeoIP technology, and at your option and consent, we may also collect precise, real-time location information from your mobile device and use that information to deliver customized content through this Website or to verify that you are where you say you are. Your mobile device may allow you to adjust settings so that location information is not used by any mobile websites or apps. If you have questions about the security and privacy settings of your mobile or tablet device, please refer to instructions from your mobile service provider or the device manufacturer.

1.4 Information About Payments

If you make a purchase, we collect Personal Information in connection with the purchase. This includes payment information, such as your credit or debit card number and other card information, and other account and authentication information, as well as billing, shipping, and contact details.

1.5 Information from Third Parties

We may collect information from third parties, including business partners and marketing agencies. This includes contact information about you provided by marketing partners when we conduct joint marketing or co-branded activities.

3. Your Choices

General

We respect your right to make choices about the way we collect, use, and disclose your Personal Information. In most cases, we ask you to indicate your choices at the time we collect your Personal Information. Even if you do not opt in, we may still use your data for other purposes described in this Privacy Policy and as permitted by applicable law.

Communication Preferences

With respect to marketing communications, we will provide you with an “opt-in” or “opt-out” mechanism depending on your location at the time we collect your Personal Information. An “opt-in” mechanism will provide you the opportunity to actively indicate your willingness to receive such further communications from us. An “opt-out” mechanism (such as an “unsubscribe” link) will provide you the opportunity to indicate that you do not want us to send you such further communications, and if you “opt-out,” we will not send you any.

Previously Expressed Preferences

You may change previously expressed preferences regarding how we use your Personal Information. If at any time you wish to be removed from our mailing list, please contact us at data.privacy@west-hn.com or indicate your preference on our privacy management page.

4. How We Share Your Information

We provide certain Personal Information to strategic partners that work with us to provide products or help us market to customers. We share Personal Information with these companies solely to provide or improve our products and advertising; we do not share Personal Information with third parties for their marketing purposes without your prior express consent.

Third-Party Vendors

We share Personal Information collected through this Website and our products with third-party vendors who act on our behalf. For example, we use third-party vendors to design and operate this Website, provide Cloud Services, conduct surveys, and provide you with products you have requested or may be interested in.

Corporate Affiliates and Corporate Business Transactions

We may share Personal Information with all WEST affiliates. In the event of a merger, reorganization, acquisition, joint venture, assignment, spin-off, transfer, or sale or disposition of all or any portion of our business, including in connection with any bankruptcy or similar proceedings, we may transfer any and all Personal Information to the relevant third party.

Compliance with Laws and Protection of Our Rights and the Rights of Others

We may disclose Personal Information when we believe in good faith that disclosure is appropriate to comply with the law, a court order, or a subpoena. We may also disclose your Personal Information to prevent or investigate a possible crime, such as fraud or identity theft, to protect the security of this Website, to enforce or apply our Cloud Services terms or other agreements, or to protect our own rights or property or the rights, property, or safety of our users or others.

This Privacy Policy applies only to information we collect. We encourage you to read the privacy policies of any third-party websites, products, or services before using them.

6. Cookies and Tracking Technologies

We use “cookies” and other technologies to collect information and support certain features of this Website. Cookies help us understand how visitors interact with our site, remember your preferences, and improve your overall experience.

7. Protecting Your Information

It is important that you take precautions to prevent unauthorized access to our products, account credentials, and your computers and other devices. If you feel that the security of your account or Personal Information has been compromised, please contact us immediately at data.privacy@west-hn.com. Please be aware that, despite our efforts, no security system is impenetrable. In the event of a security breach, we will promptly notify you and the relevant authorities where required by law.

Steps We Take to Protect Your Personal Information

We take reasonable administrative, physical, and technical measures to protect the confidentiality and security of your Personal Information submitted through this Website or through our products. Unfortunately, no website, server, or database is completely secure or “hacker-proof.” We therefore cannot guarantee that your Personal Information will not be disclosed, misused, or lost through accident or the unauthorized acts of others.

International Data Transfers

WEST operates globally with offices across China, Hong Kong, Taiwan, and Vietnam. Your information may be transferred to and processed in countries other than your own. We implement appropriate safeguards, including standard contractual clauses and data processing agreements, to ensure your data receives adequate protection in accordance with applicable data protection laws.

8. Retention of Your Information

We will retain your Personal Information for as long as necessary to fulfill the purposes described in this Privacy Policy, or for as long as is permitted or required by applicable law. If you wish to cancel your account or request that we no longer use your information to provide you with products or services, please contact us, and we will consider your request in accordance with applicable legal requirements.

9. Privacy of Minors

We do not knowingly collect, use, or disclose Personal Information from children under the age of 18 through this Website or our products. If you are a parent or guardian of a minor under 18 and you become aware that your child has provided Personal Information to us without your consent, please contact us at data.privacy@west-hn.com and we will work with you to address your requirements regarding such Personal Information. If we become aware that a minor under the age of 18 has provided us with Personal Information without parental or guardian consent, we will take steps to remove such information from our records.

10. Your Privacy Rights

In accordance with China’s Personal Information Protection Law (PIPL), which came into effect in 2021, you may have the following rights:

  • Right to Withdraw Consent at Any Time. This applies where we rely on consent to process your Personal Information. However, this does 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 products or services to you. We will advise you if this is the case at the time you withdraw your consent.
  • Right to Request Access to Your Personal Information. This enables you to receive a copy of the Personal Information we hold about you and to check that we are lawfully processing it.
  • Right to Object to Processing of Your Personal Information. This enables you to object to the processing of your Personal Information where we rely on a legitimate interest and there is something about your particular situation that makes you want to object to processing on this ground as you feel it impacts on your fundamental rights and freedoms. In some cases, we may demonstrate that we have compelling legitimate grounds to process your information that override your rights and freedoms. Where we process your Personal Information for direct marketing purposes, you also have the right to object.
  • Right to Request Correction of Your Personal Information. This enables you to have any incomplete or inaccurate Personal Information we hold about you corrected, though we may need to verify the accuracy of the new Personal Information you provide to us.
  • Right to Request Deletion of Your Personal Information. This enables you to ask us to delete or remove Personal Information where there is no good reason for us continuing to process it. However, please note that we may not always be able to comply with your request of deletion for specific legal reasons, which will be notified to you, if applicable, at the time of your request.
  • Right to Request Transfer of Your Personal Information. We will provide to you, or a third party you have chosen, your Personal Information in a structured, commonly used, machine-readable format. Note that this right only applies to automated information that you initially provided consent for us to use or where we used the information to perform a contract with you.
  • Right to Request Restriction of Processing. This enables you to ask us to suspend the processing of your Personal Information 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.
  • Right Not to Be Subject to Decisions Based Solely on Automated Processing. This applies where automated processing produces legal effects concerning you or similarly significantly affects you. Note that this right does not apply if the decision (a) is necessary for entering into or performing a contract between you and us, (b) is authorized by applicable law, or (c) is based on your explicit consent. However, in cases (a) or (c), you have the right to obtain human intervention.
  • Right to Lodge a Complaint. You have the right to lodge a complaint with the relevant data protection supervisory authority at any time.

You will not have to pay a fee to access your Personal Information (or to exercise any of your other rights). However, we may charge a reasonable fee if your request is clearly unfounded, repetitive, or excessive. Alternatively, we may refuse to comply with your request in these circumstances.

We may need to request specific information from you to help us confirm your identity and ensure your right to access your Personal Information (or to exercise any of your other rights). This is a security measure to ensure that Personal Information is not disclosed to any person who has no right to receive it. We may also contact you to ask you for further information in relation to your request to speed up our response.

We try to respond to all legitimate requests within one month. Occasionally, it may take us longer than a month if your request is particularly complex or you have made a number of requests. In this case, we will notify you and keep you updated.

11. Changes to This Policy

We are constantly improving and adding to the features and functionality of this Website and the products we offer. Because of these changes (or changes in the law), we may need to revise or update this Privacy Policy. Accordingly, we reserve the right to update or modify this Privacy Policy at any time, by posting the revised version of this Privacy Policy behind the link marked “Privacy Policy” at the bottom of this Website. Your continued use of this Website after we have posted the revised Privacy Policy constitutes your agreement to the revised Privacy Policy. However, we will honor the terms of the version in effect at the time we collected your Personal Information.
