Terms of Service

Effective Date: February 2026

Lumina Dental Ltd ("Lumina", "we", "us", or "our"), a company registered in England and Wales under company number 16067035, provides cloud-based dental practice management software and related services (the "Service").

These Terms of Service ("Terms") constitute a legally binding agreement between Lumina and the entity or individual subscribing to the Service ("Customer", "you", or "your"). By accessing or using the Service, you confirm that you have read, understood, and agree to be bound by these Terms.

1. Definitions

In these Terms, the following definitions apply unless the context requires otherwise:

  • "Acceptable Use Policy" means Lumina's acceptable use policy available at luminadental.co.uk/acceptable-use, as updated from time to time.
  • "Authorised Users" means individuals whom the Customer authorises to access and use the Service under the Customer's subscription.
  • "Confidential Information" means any information disclosed by either party to the other that is marked as confidential or that a reasonable person would understand to be confidential given the nature of the information and the circumstances of disclosure.

  • "Practice" means a single, distinct physical dental practice location operated by the Customer at a specific postal address from which dental services are provided to patients. For the avoidance of doubt, each separate physical premises at which dental care is delivered constitutes a separate Practice, regardless of whether such premises are operated under the same business name, legal entity, or ownership.

Each Surgery configured within the Service must correspond to a real, physical treatment room that exists at the associated Practice premises.
  • "Subscription Fee" means the fees payable by the Customer for access to the Service as set out in the applicable pricing plan.
  • "Subscription Term" means the initial subscription period and any subsequent renewal periods.

2. The Service

2.1 Service Description

Lumina provides a cloud-based software platform designed for dental practice management. The Service is provided on a software-as-a-service (SaaS) basis and includes, depending on the Customer's subscription tier:

  • Patient records management and clinical workflows
  • Appointment scheduling and booking
  • Billing, invoicing, and payment processing
  • Practice administration and analytics
  • Patient-facing portal for appointment management and records access
  • Optional AI-assisted features (see Section 6)

2.2 Not a Medical Device

The Service is a practice management and administrative tool. It is not a medical device, clinical decision support system, or diagnostic tool. The Service does not provide clinical advice, and no output of the Service (including any AI-generated content) should be treated as a substitute for the professional judgment of a qualified dental practitioner. All clinical decisions remain the sole responsibility of the Customer and its qualified clinicians.

2.3 Infrastructure

The Service is hosted on Amazon Web Services (AWS) infrastructure located exclusively in the United Kingdom (AWS eu-west-2, London region). All Customer Data is processed and stored within UK jurisdiction. The Service operates across multiple availability zones for resilience. Further details of our security practices are available at luminadental.co.uk/security.

3. Account Registration and Security

3.1 Eligibility

The Service is intended for use by UK dental practices, dental professionals, and their authorised staff. By registering for the Service, you represent and warrant that you are authorised to enter into this Agreement on behalf of the subscribing entity.

3.2 Account Information

You agree to provide accurate, current, and complete information during registration and to update such information to keep it accurate, current, and complete. Lumina reserves the right to suspend or terminate accounts where registration information is found to be materially inaccurate.

3.3 Account Security

You are responsible for maintaining the confidentiality of all account credentials associated with your subscription. Multi-factor authentication (MFA) is mandatory for all Authorised Users and must be completed during account setup. You must:

  • Ensure all Authorised Users comply with MFA requirements
  • Maintain strong, unique passwords for all accounts
  • Promptly revoke access for personnel who are no longer authorised
  • Notify Lumina immediately at security@luminadental.co.uk upon becoming aware of any unauthorised access or security breach

You are liable for all activities conducted through your account unless caused by a failure of Lumina's security controls.

4. Subscription and Fees

4.1 Subscription Tiers

The Service is offered across multiple subscription tiers (Starter Practice, Growing Practice, and Enterprise), each with different feature sets, usage limits, and pricing. Full details of current pricing and tier features are available on our website. The Starter Practice tier is provided free of charge, subject to the usage limits specified.

4.2 Billing

Subscription Fees are billed in advance on a monthly or annual basis, as selected by the Customer. All fees are quoted in pounds sterling (GBP) and are exclusive of VAT, which shall be added where applicable at the prevailing rate. Payment is processed via Stripe, our third-party payment processor. The Customer is responsible for maintaining valid payment information.

4.3 Renewal

Subscriptions renew automatically at the end of each billing period unless the Customer cancels before the renewal date. Lumina will provide at least 30 days' written notice of any changes to Subscription Fees, with such changes taking effect at the start of the next renewal period.

4.4 Refunds

Subscription Fees are non-refundable except where required by applicable law. If the Customer cancels a subscription mid-period, access to the Service will continue until the end of the current paid period.

4.5 Practice and Surgery Configuration

The Customer's subscription is based on the number of Practices and the features available within the Customer's selected tier. The Customer acknowledges and agrees that:

  • Accurate representation required. The Customer must configure the Service to accurately reflect its real-world dental practice operations. Each Practice configured within the Service must correspond to a genuine, distinct physical dental practice premises operated by the Customer. Each Surgery configured within a Practice must correspond to a real, physical treatment room at that Practice premises.
  • One Practice per physical location. Each separate physical premises from which the Customer delivers dental services must be configured as a separate Practice within the Service. The Customer must not consolidate multiple physical locations into a single Practice within the Service, nor create Surgeries under one Practice that are physically located at a different premises.
  • No fictitious Surgeries. The Customer must not create Surgeries within the Service that do not correspond to real, physical treatment rooms at the associated Practice premises. Surgeries must not be used as a substitute for separate Practices or to circumvent subscription tier limits.
  • Subscription adjustment. If the Customer operates multiple physical Practice locations, the Customer must subscribe to a tier and plan that covers the correct number of Practices. Operating additional Practice locations without upgrading to the appropriate subscription constitutes a material breach of these Terms.
  • Verification and audit. Lumina reserves the right to review the Customer's Practice Configuration at any time to verify that it accurately reflects the Customer's real-world operations. The Customer agrees to provide reasonable evidence of its Practice and Surgery configuration upon request (for example, CQC registration details, practice addresses, or photographs of premises). Lumina may use automated monitoring to detect configurations that are inconsistent with normal dental practice operations.
  • Remedies for misconfiguration. If Lumina determines, acting reasonably, that the Customer's Practice Configuration does not accurately reflect its real-world operations, Lumina may: (a) require the Customer to correct its configuration within 14 days; (b) upgrade the Customer's subscription to the appropriate tier and charge the applicable Subscription Fees (including retrospectively for any period of underpayment); or (c) suspend or terminate the Customer's access to the Service in accordance with Section 14.3 if the misconfiguration is not remedied within the specified period. Persistent or deliberate misconfiguration shall be treated as a material breach of these Terms.

4.6 Non-Payment

If payment fails, Lumina will notify the Customer and provide a reasonable period (not less than 14 days) to resolve the issue. Persistent non-payment may result in suspension or termination of access to the Service in accordance with Section 14.

5. Customer Data and Data Protection

5.1 Data Roles

The parties acknowledge and agree that with respect to Personal Data contained within Customer Data (including patient records, clinical notes, and any other personal information entered into the Service by the Customer or its Authorised Users):

  • The Customer is the Data Controller. The Customer determines the purposes and means of processing Personal Data within the Service.
  • Lumina is the Data Processor. Lumina processes Personal Data solely on behalf of and in accordance with the documented instructions of the Customer, as set out in the DPA.

Lumina acts as a Data Controller in its own right only with respect to:

  • Customer account and organisational information
  • Billing and payment information
  • Website visitor data (luminadental.co.uk)
  • Marketing communications (where consent has been obtained)

5.2 Data Processing Agreement

The processing of Personal Data under these Terms is governed by the Data Processing Agreement, which forms an integral part of these Terms. In the event of any conflict between these Terms and the DPA regarding data protection matters, the DPA shall prevail.

5.3 Customer Obligations as Controller

As Data Controller, the Customer is responsible for:

  • Ensuring a valid lawful basis exists for all Personal Data processed through the Service
  • Providing appropriate privacy notices to data subjects (including patients)
  • Responding to data subject access requests and other rights requests (Lumina will provide reasonable assistance as detailed in the DPA)
  • Ensuring that the Customer's use of the Service complies with all applicable data protection legislation
  • Obtaining any necessary consents from data subjects where required

5.4 Data Residency

Customer Data is hosted in the United Kingdom (AWS eu-west-2, London region). Customer Data may be processed by third-party sub-processors (for example, Stripe for payment processing) and such processing may involve transfers outside the UK. Appropriate transfer safeguards apply as set out in the DPA and the Sub-processors page.

5.5 Security Measures

Lumina implements appropriate technical and organisational measures to protect Customer Data, including:

  • Encryption at rest (AES-256) and in transit (TLS 1.2+)
  • Mandatory multi-factor authentication for all user accounts
  • Role-based access control with granular permissions
  • Comprehensive audit logging of all data access and modifications
  • 35-day rolling backups with point-in-time recovery
  • Multi-availability-zone infrastructure for resilience

Full details of our security practices are set out on our Security page and in the DPA.

5.6 Incident Notification

In the event of a Personal Data breach affecting Customer Data, Lumina will notify the Customer without undue delay upon becoming aware of the breach. Notification will include, to the extent known, the nature of the breach, the categories of data affected, and the measures taken or proposed to address the breach. The parties' respective obligations regarding breach notification are set out in detail in the DPA.

6. AI-Assisted Features

6.1 Availability and Activation

The Service includes optional AI-assisted features (such as clinical note generation, appointment suggestions, and other automated assistance). AI features are not enabled by default. The Customer must actively choose to enable AI features and may disable them at any time. Usage of AI features is subject to the limits of the Customer's subscription tier.

6.2 How AI Data is Handled

When AI features are used:

  • Prompts are sanitised on a best-effort basis before processing to remove or minimise identifiable patient information
  • Prompts are stored encrypted (AES-256) in our UK-based infrastructure and are automatically deleted after 24 hours
  • Only metadata (the identity of the user who initiated the prompt and the timestamp) is retained beyond 24 hours for audit and compliance purposes
  • No identifiable patient data is used for AI model training
  • All AI processing occurs within UK-based infrastructure. No Customer Data is transmitted outside the UK for AI processing

For full details, see our AI Usage Policy.

6.3 Limitations and Disclaimers

AI-generated outputs are provided as a convenience and assistive tool only. The Customer acknowledges and agrees that:

  • AI features do not constitute clinical decision support and must not be relied upon as such
  • All AI-generated outputs must be reviewed by a qualified professional before being acted upon or incorporated into clinical records
  • Lumina does not warrant the accuracy, completeness, or suitability of AI-generated content for any particular purpose
  • The Customer is solely responsible for verifying and approving any AI-generated content before use
  • Lumina accepts no liability for any clinical decision made in reliance on AI-generated content

7. Intellectual Property

7.1 Lumina's IP

The Service, including all software, source code, algorithms, user interfaces, designs, documentation, trademarks, and other intellectual property embodied in or related to the Service, is and remains the exclusive property of Lumina Dental Ltd and its licensors. Nothing in these Terms transfers any ownership of Lumina's intellectual property to the Customer.

7.2 Licence to Use the Service

Subject to the Customer's compliance with these Terms and payment of applicable Subscription Fees, Lumina grants the Customer a non-exclusive, non-transferable, non-sublicensable, revocable licence to access and use the Service during the Subscription Term for the Customer's internal dental practice management purposes.

7.3 Customer Data Ownership

The Customer retains all rights, title, and interest in and to Customer Data. Lumina acquires no ownership rights in Customer Data. The Customer grants Lumina a limited licence to host, process, and transmit Customer Data solely as necessary to provide and maintain the Service in accordance with these Terms and the DPA.

7.4 Feedback

If the Customer provides suggestions, feature requests, or other feedback regarding the Service ("Feedback"), Lumina may use such Feedback without restriction or obligation to the Customer. The Customer is not required to provide Feedback.

8. Aggregated and Anonymised Data

Lumina may create aggregated and anonymised datasets derived from Customer Data, provided that such data:

  • Has been irreversibly anonymised such that it cannot, by any reasonable means, be used to identify any individual, patient, or specific dental practice
  • Is combined with data from multiple sources such that no individual Customer's data can be isolated or reconstructed

Lumina may use such aggregated and anonymised data for the purposes of:

  • Improving and developing the Service
  • Generating industry benchmarks and analytics
  • Conducting research and statistical analysis
  • Compiling reports on industry trends

For the avoidance of doubt, aggregated and anonymised data does not constitute Customer Data or Personal Data for the purposes of these Terms or the DPA. Lumina owns all rights in aggregated and anonymised datasets it creates.

Lumina will not attempt to re-identify anonymised data. Lumina will not disclose or sell Customer Data or identifiable patient information to any third party except as necessary to provide the Service or as required by law.

9. Service Availability

9.1 Uptime Target

Lumina is designed for and targets 99.9% availability, measured on a calendar month basis. This is a design objective and operational target, not a guarantee. Lumina does not currently offer formal SLA credits for downtime. Enterprise customers may negotiate specific availability commitments under a separate agreement.

9.2 Scheduled Maintenance

Lumina may perform scheduled maintenance on the Service. Where practicable, scheduled maintenance will be conducted outside of business hours (08:00 to 19:00 UK time, Monday to Friday). Lumina will provide reasonable advance notice of scheduled maintenance that is expected to cause service disruption. Scheduled maintenance periods are excluded from availability calculations.

  • Issues caused by the Customer's systems, networks, or equipment
  • Issues caused by third-party services or internet connectivity
  • Suspension due to the Customer's breach of these Terms

Lumina maintains a target recovery time objective (RTO) of 4 hours for critical service components. Backups are maintained on a 35-day rolling basis with point-in-time recovery capability.

9.5 Real-Time and Emergency Alert Features

The Service includes real-time features, including the practice-wide emergency alert system, that rely on active internet connectivity, WebSocket connections, and device availability. The Customer acknowledges and agrees that:

  • Real-time features, including emergency alerts, are provided as a supplementary communication tool and must not be relied upon as the sole or primary method of raising an emergency or communicating urgent information within the practice
  • The delivery and timeliness of real-time notifications depend on factors outside Lumina's control, including the Customer's local network conditions, internet connectivity, device state (e.g. whether a device is powered on, connected, and running the Service), and the performance of third-party infrastructure providers
  • Lumina does not warrant that real-time features will operate without latency, interruption, or failure in all circumstances
  • The Customer is responsible for maintaining independent emergency procedures and communication methods (such as verbal alerts, physical alarm systems, intercoms, or other manual processes) in accordance with applicable regulatory requirements, including Care Quality Commission (CQC) standards and the Customer's own risk assessments
  • Lumina accepts no liability for any loss, injury, or damage arising from the failure, delay, or unavailability of real-time features, including emergency alerts, to the fullest extent permitted by law

10. Support

Support is provided in accordance with the Customer's subscription tier. Support response times are targets only and are not guaranteed unless expressly agreed in writing.

The courts of England and Wales shall have exclusive jurisdiction to settle any dispute or claim arising out of or in connection with these Terms.

20. General Provisions

20.1 Force Majeure

Neither party shall be liable for any failure or delay in performing its obligations under these Terms to the extent that such failure or delay is caused by circumstances beyond that party's reasonable control, including (without limitation) natural disasters, acts of government, pandemic, epidemic, war, terrorism, civil unrest, power failure, internet disruption, or failure of third-party infrastructure providers. The affected party shall promptly notify the other party and use reasonable efforts to mitigate the impact. If a force majeure event continues for more than 60 consecutive days, either party may terminate these Terms by written notice.

20.2 Severability

If any provision of these Terms is found by a court of competent jurisdiction to be invalid, illegal, or unenforceable, that provision shall be deemed modified to the minimum extent necessary to make it valid, legal, and enforceable. If such modification is not possible, the provision shall be severed from these Terms without affecting the validity and enforceability of the remaining provisions.

20.3 No Waiver

A failure or delay by either party to exercise any right or remedy under these Terms shall not constitute a waiver of that right or remedy. A single or partial exercise of any right or remedy shall not prevent any further exercise of that or any other right or remedy.

20.4 Entire Agreement

These Terms, together with the DPA, the Acceptable Use Policy, the Privacy Policy, and any other documents expressly incorporated by reference, constitute the entire agreement between the parties with respect to the subject matter hereof and supersede all prior or contemporaneous agreements, understandings, and representations, whether written or oral.
