SmileBooth by HYPERMIND · TAX ID: EL802834643 · Greece
Effective: May 14, 2026 · Last updated: May 14, 2026


1. Who We Are

SmileBooth is a product developed and operated by HYPERMIND (Greek Tax ID: EL802834643), a technology and digital product studio based in Greece ("we", "us", "our"). SmileBooth provides AI-powered smile visualization tools for dental clinics, accessible at smilebooth.ai (the marketing site) and app.smilebooth.ai (the clinic dashboard and patient-facing application) (collectively, the "Service").

HYPERMIND acts as the data controller in respect of personal data processed through the Service. Where dental clinics use SmileBooth to process data about their patients, the clinic may act as an independent controller or joint controller; we address this relationship in Section 7.


2. Scope of This Policy

This Privacy Policy applies to:

  • Visitors to smilebooth.ai (the marketing and informational website).
  • Dental clinic staff and administrators using app.smilebooth.ai (the SmileBooth dashboard).
  • Dental patients who interact with the SmileBooth smile visualization experience, whether via a tablet in the clinic, a QR code link, or any embedded integration.

It does not apply to the Hypermind corporate website at hypermind.io, which is governed by Hypermind's own privacy policy.

4. How We Use Your Data

4.1 Providing and Improving the Service

  • Generating photorealistic smile visualizations using our AI model.
  • Operating clinic dashboards, authentication, and account management.
  • Delivering patient visualization results to the patient's screen or, with consent, to the patient's email or phone.
  • Diagnosing technical issues and improving AI model quality.

4.2 Business Operations

  • Processing demo requests and responding to sales inquiries.
  • Managing clinic subscriptions and billing.
  • Sending transactional communications (account confirmations, product updates).

4.3 AI Model Development

Important: We do not use patient facial photographs or AI-generated smile images to train or fine-tune our AI models without explicit, freely given, separate, and informed consent from both the clinic and, where applicable, the patient. Aggregated and anonymized technical performance metrics (rendering speed, accuracy scores) may be used internally for model improvement.

4.4 Analytics & Marketing

We use aggregated, anonymized usage data to understand how the Service is used and to communicate with prospective clinic customers. We do not engage in targeted advertising using patient data.


5. Legal Basis for Processing (GDPR)

As an entity established in Greece, we process personal data in compliance with the EU General Data Protection Regulation (GDPR) (Regulation 2016/679).

6. Biometric & Health-Adjacent Data

Facial photographs and AI-generated smile images may constitute biometric data or health-related data under the GDPR — classified as "special category" personal data requiring heightened protection.

We treat all patient facial images as special category data. This means:

  • We process them only for the specific purpose of generating a smile visualization during the session.
  • Images are not retained beyond the session unless the clinic or patient explicitly elects to save the result.
  • Where images are saved, they are stored with encryption at rest.
  • Images are never sold, licensed, shared with third-party advertisers, or used to build facial recognition datasets.
  • Clinics are responsible for obtaining appropriate patient consent before initiating a visualization session, and must inform patients that their image will be processed by AI software operated by HYPERMIND

7. Data Sharing & Third Parties

7.1 Clinic Partners

Dental clinics that use SmileBooth have access to data generated within their account, including saved visualizations and lead capture data submitted by their patients. Clinics are independent data controllers for the purposes of their own patient records.

7.2 Service Providers (Processors)

We share data with carefully selected third-party processors who assist us in delivering the Service. All processors are bound by data processing agreements and may only use data on our instructions.

7.3 Legal Disclosures

We may disclose personal data where required by applicable law, court order, or regulatory authority, or to protect the rights and safety of users or the public.

7.4 Business Transfers

In the event of a merger, acquisition, or sale of assets, personal data may be transferred to the successor entity, subject to equivalent privacy protections.


8. International Data Transfers

Our primary infrastructure is located within the European Economic Area (EEA). Where data is transferred outside the EEA, we ensure appropriate safeguards are in place, including Standard Contractual Clauses (SCCs) approved by the European Commission.

  • Rectification: Request correction of inaccurate or incomplete data.
  • Erasure: Request deletion of your data, subject to legal obligations.

To exercise any right, contact us at privacy@hypermind.io. We will respond within 30 days.

Note: Patients who have undergone a smile visualization at a clinic may need to contact their dental clinic to exercise certain rights, as the clinic is the controller of their consultation records.


11. Cookies & Tracking

  • Strictly necessary cookies: Required for authentication, session management, and security. Cannot be disabled.
  • Functional cookies: Remember your preferences (e.g. language, clinic settings).
  • Analytics cookies: Help us understand usage patterns using aggregated data. You may opt out via our cookie consent banner.

The patient-facing smile visualization experience (accessed via QR code or tablet) is designed to be minimal-cookie and does not use advertising or third-party tracking cookies.


12. Children's Privacy

The SmileBooth Service is directed at dental clinics and their adult patients. We do not knowingly process facial images of children under the age of 16 without verified parental or guardian consent. Clinics are responsible for ensuring appropriate consent is obtained before allowing a minor to use the smile visualization feature.


13. Security

We implement appropriate technical and organizational measures to protect personal data against unauthorized access, loss, or alteration, including:

  • Encryption of data in transit (TLS) and at rest (AES-256).
  • Role-based access controls restricting data access to authorized personnel only.
  • Regular security assessments and penetration testing.
  • Secure deletion of patient images at end of session.

In the event of a data breach likely to result in risk to your rights, we will notify relevant supervisory authorities within 72 hours and affected individuals without undue delay, as required by GDPR.


14. Changes to This Policy

We may update this Privacy Policy from time to time. When we make material changes, we will update the "Last Updated" date above and, where appropriate, notify clinic administrators by email. Continued use of the Service after the effective date constitutes acceptance of the revised policy.
