1. Scope of this policy
This Privacy Policy applies to personal information that KEEN BEST TECHNOLOGY LIMITED (“KEEN BEST”, “we”, “us”) processes as the responsible party, including personal information collected through:
- the web pages we publish for this company, including https://keenbest.com.tw/hk/ and the support and SMS pages linked from it;
- our customer support operations, including support requests and product demonstration bookings;
- our SMS status update programme, described in section 2 and in our SMS Privacy Policy;
- the cloud contact centre, AI customer service and omni-channel customer engagement services we provide to business customers.
KEEN BEST TECHNOLOGY LIMITED (Hong Kong) and KEENBEST INFORMATION TECHNOLOGY LIMITED (銳通資訊科技有限公司, Taiwan, Unified Business Number 85098969) are two separate legal entities operating under the KEEN BEST brand. Each entity is responsible for its own services in its own jurisdiction. Where you interact with services provided by the Taiwan entity, that entity's own privacy policy applies. This policy covers the Hong Kong entity.
Where we process personal information on behalf of a business customer as part of the services they have engaged us to operate, that customer determines how the information is used and we act on their instructions under our agreement with them.
2. Mobile information and SMS consent
No mobile information will be shared with third parties or affiliates for marketing or promotional purposes.
Text messaging originator opt-in data and consent will not be shared with any third parties.
We do not sell, rent, trade or lease mobile phone numbers, SMS consent records or any other mobile information to any party, for any purpose.
Sharing with subcontractors who provide support services strictly on our behalf, such as the messaging infrastructure that transmits a message to the mobile carrier, is limited to what is necessary to deliver the message and is subject to the restrictions in section 6.
Our SMS programme is transactional only
KEEN BEST operates one SMS programme. It sends transactional status updates to business contacts who have submitted a support request or booked a product demonstration with us, and who have given explicit consent to receive text messages at the point of submission.
We do not send marketing or promotional text messages. We do not add mobile numbers collected through the SMS consent flow to any marketing list, and we do not use them for any purpose other than the status updates described here and in our SMS Terms and Conditions.
| What the messages contain | Status updates for the specific support request or demo booking the recipient submitted: request received, status changed, request resolved, booking confirmed and booking reminder. Each message identifies KEEN BEST and cites the request or booking number. |
|---|---|
| Message frequency | Up to 6 messages per request. |
| Cost | We do not charge for these messages. Message and data rates may apply from the recipient's mobile carrier. |
| How consent is obtained | Through a dedicated SMS consent checkbox on our public opt-in form. The checkbox is not selected by default, is separate from acceptance of general terms, and is not required in order to submit the form. The mobile number field stays disabled until consent is given, so we do not collect a mobile number from anyone who has not opted in. |
| How to stop | Reply STOP to any message. Reply HELP for help. Or contact support@keenbest.com.hk or +852 2511 0933. No account or sign-in is required. |
Full details of the mobile data we collect for this programme, how long we keep it and who processes it are set out in our SMS Privacy Policy, which forms part of this policy.
3. Information we collect
| Category | What it includes |
|---|---|
| Contact details | Name, business email address, company name, job title, and telephone or mobile number where you provide one. |
| Support and enquiry content | The content of a support request, enquiry or demonstration booking you submit, and our correspondence with you about it. |
| Mobile number and SMS consent record | Where you opt in to SMS status updates: the mobile number you enter, the fact that you selected the consent checkbox, the date and time of that action, the version of the consent wording shown to you, and the source IP address of the submission. |
| Message delivery data | Delivery status information returned by the mobile carrier for each message we send, used to diagnose delivery problems. |
| Technical data | Information your browser sends when you visit our pages, such as IP address, browser type and the pages you view, used to keep the site secure and working. |
| Service account data | Where you are a business customer using our services, the account and configuration information needed to provide them. |
We do not seek to collect sensitive personal information through our public web pages. Please do not include sensitive information in a support request unless it is necessary for us to help you.
4. Why we use it
- To respond to a support request, enquiry or demonstration booking you submit.
- To send status updates about that request or booking by email and, where you have opted in, by SMS.
- To provide, operate, support and improve the services a business customer has engaged us to deliver.
- To keep records demonstrating, if required, that consent to receive text messages was given and which version of the consent wording was agreed to.
- To diagnose message delivery problems and improve reliability.
- To keep our systems and pages secure and to prevent misuse.
- To meet legal, regulatory and record-keeping obligations that apply to us.
Where we rely on your consent, you may withdraw it at any time as described in section 10. Withdrawing consent to SMS does not affect our ability to respond to your request by email.
5. How we share information
We share personal information only in the following situations:
- Service providers acting for us. See section 6. They may process the information only to perform the service we have engaged them for, and may not use it for their own purposes.
- Where you ask us to. For example when you ask us to coordinate with a third party on your request.
- Legal requirements. Where we are required to disclose information by law, by a regulator, or to establish or defend legal claims.
- Business transfer. If our business or part of it is transferred, information may transfer with it, subject to this policy continuing to apply.
We never sell, rent, trade or lease personal information.
No mobile information will be shared with third parties or affiliates for marketing or promotional purposes, and text messaging originator opt-in data and consent will not be shared with any third parties. This restriction applies in addition to everything else in this section.
6. Service providers who process data for us
| Party | Role and limits |
|---|---|
| Amazon Web Services | Operates the messaging and cloud infrastructure we use. Processes a mobile number only to transmit the message to the carrier. Amazon Web Services does not share end user phone numbers with third parties for marketing or promotional purposes. |
| Mobile carriers | Deliver a message to the recipient's device and apply network level opt-out handling where applicable. |
| Hosting and email providers | Host our web pages and carry our support email. Access is limited to what is needed to run those services. |
We require each provider to protect the information, to use it only for the service they provide to us, and not to use it for their own marketing.
7. Transfers outside Hong Kong
We are based in Hong Kong. Some of our service providers operate in other jurisdictions, so information may be processed outside Hong Kong. Where that happens we take steps to ensure the information continues to receive a comparable level of protection, including contractual protections with the provider.
8. How long we keep information
| Information | Retention |
|---|---|
| Support request and correspondence | For as long as needed to handle the request and for a reasonable period afterwards for reference and record-keeping. |
| Mobile number collected for SMS updates | Only for as long as needed to operate the status update service for the related request, after which it is deleted or anonymised. |
| SMS consent record | For as long as we may need to evidence that consent was given. |
| Business customer account data | For the duration of the engagement and any period required by our agreement or by law. |
9. How we protect information
We use technical and organisational measures appropriate to the information we hold, including encryption in transit, access controls limiting access to authorised personnel, and restrictions on how service providers may use the information. No system can be guaranteed completely secure, but we review our measures and act on issues we identify.
10. Your rights
You may ask us to:
- confirm whether we hold personal information about you, and provide a copy;
- correct information that is inaccurate or incomplete;
- delete information we no longer need to keep;
- stop sending you text messages, or withdraw any consent you have given.
Contact support@keenbest.com.hk. You do not need an account or a login to make a request. We will respond within a reasonable period. If you are not satisfied with our response you may raise the matter with the relevant data protection authority.
11. Cookies and similar technologies
Our company information, SMS opt-in, SMS terms and SMS privacy pages do not set advertising or tracking cookies. Other pages on the wider keenbest.com.tw website, which is operated together with our Taiwan affiliate, may use cookies for site functionality and analytics. You can reject or delete cookies through your browser settings; some site features may then not work as intended. We do not use cookies to build advertising profiles, and we do not combine cookie data with mobile numbers collected through the SMS consent flow.
12. Children
Our services are provided to businesses and organisations and are not directed at children. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, contact us and we will delete it.
13. Changes to this policy
We may update this policy from time to time. The current version is always published at this URL and the date at the top of the page reflects the most recent update. Where a change materially affects how we use personal information we will take reasonable steps to notify affected individuals.
