MintScreen is operated by Mintwell Limited ("MintScreen", "we", "us" or "our"), a New Zealand business.
We respect your privacy and are committed to protecting the personal and health information you provide when using the MintScreen mobile application, website and related services.
This Privacy Policy explains what information we collect, why we collect it, how it is used and protected, who it may be shared with, and the choices you have regarding your information.
MintScreen handles health information in accordance with applicable New Zealand privacy and health-information requirements, including the Privacy Act 2020 and Health Information Privacy Code 2020.

Account and Contact Information
When you create a MintScreen account, we collect information including:
Your first and last name
Email address
Mobile phone number
Age range
Account identifiers
Login and authentication information
MintScreen collects an age range rather than your exact date of birth.

Oral Health Photographs
MintScreen requires five photographs of your mouth, teeth and gums as part of an oral health screening.
You can take these photographs using your device camera or select appropriate images using your device's photo picker.
Photos taken through MintScreen are not saved to your device's camera roll by MintScreen.
Before upload, images are re-encoded in a way that removes original image metadata such as GPS location, device model and original capture timestamp.
The photographs are securely uploaded to private cloud storage and associated with your screening.

Screening results
Dental professional observations
Findings and recommendations
Clinician comments
Referral recommendations
Oral health reports

Our Privacy Policy
MintScreen screening terms
Marketing communications
Parent or guardian consent where required
We may also record the date and time consent was provided.
Technical Information
MintScreen does not currently use third-party analytics, advertising or tracking SDKs.
The MintScreen app does not intentionally collect device identifiers, advertising identifiers, precise or approximate location, app-usage analytics, crash telemetry or behavioural tracking information.
As with most internet-based services, infrastructure providers may process technical information such as IP addresses in ordinary server logs when providing their services.

MintScreen does not sell your personal or health information.
3. Dental Professional Review
Every completed MintScreen screening is reviewed by a dental professional before the final report is provided to you.
The reviewing dental professional may have access to information including:
Your name
Email address
Mobile number
Age range
Questionnaire answers
Additional concerns you provide
Your five oral health photographs
Relevant previous screening history
Screening findings

Your age range
Your oral health questionnaire answers
Additional concerns you provide
Temporary access to the oral health photographs submitted for your screening
MintScreen does not intentionally provide your name, email address, mobile number or MintScreen account identifier to the AI service as part of this process.
AI-generated information is used as a preliminary aid for the clinical review process. The AI-generated draft is not provided directly to you as your final MintScreen report.
A dental professional reviews the screening before the final report is made available.
5. Service Providers and Sharing of Information
We may use trusted third-party providers where necessary to operate MintScreen and provide the service you request.
These currently include:
Supabase
MintScreen uses Supabase for authentication, database services, private file storage and backend functionality.
Information processed or stored through Supabase may include account information, contact information, oral health questionnaire responses, photographs, reports, consent records and other information required to provide MintScreen.
Resend
MintScreen uses Resend to deliver transactional emails.
Information processed through Resend may include your email address, first name and information contained in emails sent to you. Depending on the email, this may include information relating to your MintScreen screening or report.
Artificial Intelligence Providers
MintScreen uses the Rork Toolkit AI service to facilitate AI-assisted analysis. This may involve processing through AI models provided by Google and OpenAI.
Information provided for AI processing may include your age range, questionnaire responses, additional concerns and temporary access to your submitted oral health photographs.
We may also disclose information where:
Required by law
Necessary to protect the security or integrity of MintScreen
Required by an appropriate regulatory authority
Necessary for professional or legal advice
6. Storage and Security
We take reasonable technical and organisational measures to protect personal and health information against loss, misuse, unauthorised access, disclosure, alteration and destruction.
Security measures used by MintScreen include:
Encrypted network connections
Secure authentication
Private cloud storage for oral health photographs
Role-based access controls
Database-level access controls
Restricted clinician and administrator accounts
Secure server-side credentials
Audit records for relevant staff actions
User sessions are protected using secure device storage where supported.
No method of electronic storage or transmission can be guaranteed to be completely secure.
7. Data Storage and International Processing
MintScreen's primary database and oral health photo storage are provided through Supabase and are hosted using Amazon Web Services infrastructure in Sydney, Australia.
Some information may also be processed outside New Zealand and Australia when we use service providers to deliver MintScreen.
This includes transactional email processing through Resend and AI-assisted processing through the Rork Toolkit and associated AI providers, which may involve processing in other countries, including the United States.
Where personal or health information is processed outside New Zealand, we take reasonable steps to ensure it is handled in accordance with applicable privacy requirements.
8. Data Retention
Because MintScreen provides an oral health screening service, some information forms part of a health or clinical record and may be subject to legal and professional record-retention requirements.
Applicable New Zealand health-information requirements may require certain identifiable health information to be retained for a minimum period, including where a user closes or requests deletion of their MintScreen account.
We retain personal information only for as long as reasonably necessary to provide our services and meet applicable legal, regulatory, clinical, professional, security and operational requirements.
Where personal or health information is disclosed to or processed by service providers outside New Zealand, we take reasonable steps to ensure appropriate privacy safeguards are in place and that the information is handled in accordance with applicable New Zealand privacy and health-information requirements.
9. Accessing or Correcting Your Information
You may request access to personal information we hold about you or ask us to correct information you believe is inaccurate.
To make a request, contact:
We may need to verify your identity before processing your request.
10. Account Closure and Data Deletion
You can initiate closure of your MintScreen account directly from within the MintScreen app by selecting Account & Privacy → Delete Account.
For security, you will be required to confirm your identity and confirm your decision before your account is closed.
Once your account is closed, the closure is permanent. You will no longer be able to sign in to the account or access previous reports through the MintScreen app.
Account-level personal information that is no longer required, such as your name, email address and mobile number associated with your active account profile, will be removed or de-identified. Your marketing preferences will also be removed or disabled and your information will no longer be used by MintScreen for future marketing.
Because MintScreen provides an oral health screening service, certain information forms part of your health or clinical record and must be retained in accordance with applicable New Zealand legal, regulatory and professional record-keeping requirements.
This may include:
Oral health assessments
Questionnaire responses
Additional symptoms or concerns you provided
Oral health photographs
Dental professional assessments and reports
Clinical notes
Referral information
Relevant AI-assisted draft information used during clinical review
Consent records
Relevant clinical and audit history
Under applicable New Zealand health-information retention requirements, identifiable health information may need to be retained for a minimum period of 10 years from the most recent date on which relevant health services were provided.
Closing your MintScreen account therefore does not necessarily result in deletion of your clinical record or oral health photographs.
Retained clinical information remains subject to MintScreen's privacy and security controls and is not used for marketing purposes.
Account closure does not automatically delete information that has previously been processed by third-party service providers, such as transactional email or AI service providers. Information held by those providers is subject to their applicable retention and privacy practices.
If you would like to request access to retained information, ask us to correct information, or have questions about deletion or retention of your information please contact:
Please include "MintScreen Privacy Request" in the subject line. We may need to verify your identity before responding to your request
11. Camera and Photo Access
MintScreen requests access to your device's camera when you choose to take the photographs required for an oral health screening.
MintScreen may also allow you to select individual images using your device's photo picker.
MintScreen does not require access to your entire photo library for this purpose.
Camera permissions can be managed through your device settings.
12. Children's Privacy
MintScreen supports users under the age of 16 only where appropriate parent or guardian consent has been provided.
When a user selects an age range indicating they are under 16, MintScreen requires parent or guardian consent before the screening can proceed.
The consent is recorded along with the time it was provided.
We take additional care when handling personal and health information relating to children and young people and process this information in accordance with applicable privacy and health-information requirements.
13. Marketing Communications
Marketing communication is separate from the consent required to use MintScreen.
If you choose to receive marketing communications, we may use your contact information to communicate with you about MintScreen.
You can withdraw your marketing consent or unsubscribe from marketing communications.
Withdrawing marketing consent does not prevent us from sending necessary service-related communications about your account, screening or report.
14. Oral Health Disclaimer
MintScreen provides an oral health screening service designed to provide information and guidance based on the information and photographs submitted.
MintScreen does not replace a comprehensive in-person dental examination, diagnosis or treatment by a dentist.
Photographs and remote screening may not identify every dental or oral health condition.
If you are experiencing significant pain, swelling, uncontrolled bleeding, facial trauma, difficulty breathing or another urgent dental or medical concern, seek appropriate professional dental or medical care.
15. Changes to This Privacy Policy
We may update this Privacy Policy from time to time to reflect changes to MintScreen, our privacy practices, service providers or applicable requirements.
The latest version will be published on this page with the date it was last updated.
