This policy explains how KEEN BEST TECHNOLOGY LIMITED collects, uses and protects mobile phone numbers and consent data in connection with the SMS status update messages we send about support requests and demo bookings. It should be read together with our SMS Terms and Conditions.
Our commitments regarding mobile numbers and SMS consent
- No mobile numbers 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.
- Messages are delivered using messaging infrastructure operated by Amazon Web Services on our behalf. Amazon Web Services does not share end user phone numbers with third parties for marketing or promotional purposes.
What we collect
- The mobile phone number you enter on our SMS opt-in page. This field is only available after you select the SMS consent checkbox, so we do not collect a mobile number from users who have not opted in.
- Your consent record, which includes the fact that you selected the SMS 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.
- The identifier of the support request or demo booking that the messages relate to.
- Delivery status information returned by the mobile carrier for each message sent.
Why we collect it
- To send you status updates about the support request or demo booking you submitted.
- To demonstrate, if required, that you consented to receive those messages and which version of the consent wording you agreed to.
- To diagnose delivery problems and improve message reliability.
We do not use the mobile number collected through this flow to send marketing or promotional messages, and we do not add it to any marketing list.
Who processes the data
| Party | Role |
|---|---|
| KEEN BEST TECHNOLOGY LIMITED | Collects the mobile number and consent record, and initiates each message in response to an event in our support or scheduling system. |

No other party receives your mobile number or consent data. We do not sell, rent or trade this data, and we do not disclose it to affiliates for their own messaging programmes.
How long we keep it
We retain mobile numbers and consent records only for as long as necessary to operate the status update service and to meet our record-keeping obligations, after which they are deleted or anonymised. Consent records are retained for as long as we may need to evidence that consent was given.
