SMS Privacy Notice
How Rexabook collects, uses and protects information relating to our appointment text-message (SMS) service.
Last updated: 31 July 2026
1. Who we are
Rexabook is an online appointment-booking and payments platform. Rexabook is operated by Mirrexa US LLC, whose registered address is at 30 N Gould St, Ste R, Sheridan, WY 82801, USA. In this notice, "we", "us" and "Rexabook" mean Mirrexa US LLC.
This notice covers only the appointment text-message (SMS) programme. Our full data practices are set out in our Privacy Policy, and the terms of the messaging programme in our SMS Terms of Service.
2. The information we collect
When you book an appointment with a business that uses Rexabook, we collect and process:
- Your mobile phone number.
- Your consent to receive appointment-related text messages, captured at the point of booking.
- Booking details needed to send you relevant messages (for example the business name and the appointment date and time).
- Message-delivery metadata, such as whether a message was delivered and whether you replied STOP.
3. How we use your mobile information
We use your mobile number and your consent solely to send transactional, appointment-related text messages on behalf of the business you booked with: booking confirmations, reminders, reschedules, cancellations and, where the business uses card-on-file features, late-cancellation or no-show charge notices. We do not use this programme for marketing or promotional messages.
Optional marketing SMS (for example offers or reminders to rebook) is a separate programme, sent only to people who have given a separate, explicit opt-in, and can be switched off without stopping your appointment texts.
4. How we share your mobile information
No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. Text-messaging originator opt-in data and consent are not shared with any third parties.
We share your mobile number only with the following, and only to deliver the messages you have consented to:
- Twilio, our messaging provider, which transmits the messages to your mobile carrier.
- The business you booked your appointment with, which is the sender of the appointment messages and the controller of your booking record.
5. Opt-out and help
You can opt out of these messages at any time by replying STOP to any message. You will receive a single confirmation that you have been unsubscribed, and no further messages will be sent to that number unless you opt in again. Reply HELP for help, or contact us at team@rexabook.com. Opt-outs are processed automatically and immediately, and are honoured regardless of any instruction from the business.
6. Message frequency and cost
Message frequency varies and depends on your bookings and appointment activity. Message and data rates may apply, depending on your mobile plan and carrier. Rexabook does not charge you for receiving messages.
7. Data retention
We retain your mobile number and consent records for as long as needed to provide the service and to evidence your consent, and thereafter only as required by law. Opt-out flags are retained for as long as the client record exists, so that the opt-out continues to be honoured.
8. Your rights
You have rights over your personal data under applicable data protection law, including the right to access, correct or erase your information. For full details, including how to exercise those rights, see our Privacy Policy.
