The record

Availability: ShowUp is temporarily offline while the product is being improved.
Purpose: ShowUp is a software-as-a-service platform for UK private healthcare clinics that sends appointment reminder SMS messages and helps recover cancelled or unattended appointment slots.
Recovery workflow: ShowUp can offer a freed slot by SMS to one waitlisted patient at a time, then alert staff to book that patient manually.
Appointment system limits: ShowUp does not book, move or cancel appointments in a clinic’s practice management system, and it does not write to the clinic’s diary.
Patient data limits: ShowUp is not a patient record or clinical system and must not be used to hold clinical records, diagnoses, treatment details or other special category health data.
Cliniko integration: The Cliniko connection is read-only, and the clinic’s API credentials are stored encrypted.
Booking API: The terms describe an API key clinics may be issued for submitting bookings, and say ShowUp may rate limit, suspend or revoke a key that risks the platform or patients.
Security: The published security measures include enforced multi-factor authentication, per-clinic database isolation, encryption in transit, audit logging and automated retention and deletion.
Data locations: The sub-processor list says patient data is processed in the EU by Supabase in Ireland, Twilio in Ireland and Railway in EU West, while Resend processes account data and recovery alert details in the United States.
Data retention: Patient data is automatically deleted 24 months after a patient’s last appointment, and clinic data is deleted within 31 days after subscription cancellation.
Support: The terms provide support contact by email at [email protected].
Service availability: ShowUp says it aims to keep the platform available at all times but does not guarantee delivery of individual SMS messages.
Headquarters: Stapleford, Nottingham, UK
