1. Introduction

RaviGauge is a free educational application developed by the Academy of Fixed Orthodontics (AFO) to support orthodontic education, practical training and simulation.

The application is intended for students and dental professionals participating in or interested in AFO educational programmes.

AFO respects the privacy of its users. This Privacy Policy explains the application's access to device resources, processing of information, data storage, external services and limitations of responsibility.

RaviGauge is designed to operate without user registration, account creation, cloud-based exercise storage or automatic uploading of training images and annotations.

2. Educational Purpose

RaviGauge is strictly an educational and simulation application.

It is designed to assist users in practising:

• Identification of the centre of the clinical crown.

• FA point and FACC axis positioning.

• Horizontal reference identification.

• Orthodontic bracket positioning exercises.

• Centre-of-centre concepts.

• Visual comparison of orthodontic landmarks and bracket overlays.

The application is intended for use with typodonts, artificial teeth and dental training models.

It is NOT intended for patient use, clinical diagnosis, clinical treatment planning or providing clinical bracket-placement instructions.

3. Camera Permission and Image Processing

RaviGauge requires camera access to provide its principal educational functions.

The camera is used to:

• Display the live camera preview.

• Capture images of typodonts and artificial dental models.

• Allow users to annotate captured training images.

• Display educational landmark and bracket overlays.

• Provide the Live View comparison feature.

Captured images are processed locally on the device for the purposes of the exercise.

The application's documented implementation does not save captured exercise photographs as persistent image files or automatically upload them to AFO or an external server.

Camera images are temporary exercise data.

Users should avoid including identifiable patient information, personal documents or other sensitive information in captured images.

Camera permission can be controlled through the device's operating-system settings. Denying camera permission may prevent the camera-dependent functions from operating.

4. Annotation and Exercise Information

During an exercise, RaviGauge generates temporary annotation information, which may include:

• Selected FDI tooth number.

• Crown outline coordinates.

• FA point position.

• FACC axis position and angle.

• Horizontal reference axis.

• Bracket overlay position, dimensions and rotation.

• Slot alignment information.

• Educational comparison feedback.

This information is maintained temporarily in the application's memory (RAM) while the exercise is running.

The documented implementation does not write new exercise annotation JSON files to persistent storage or automatically transmit annotation information to AFO.

Temporary exercise information is cleared when the relevant application controller is destroyed. Users should not rely on the application to retain exercise photographs or annotations after a session.

5. Locally Stored Application Preferences

RaviGauge does not require a user account, registration, email address or password.

The application retains a limited local application-state preference relating to the AFO educational information prompt.

The application records whether this prompt has been completed so that it does not repeatedly appear after completion.

The user's Yes/No response to the educational prompt is not retained.

This limited application-state information is stored locally on the device and is not intended to identify or profile the user.

Uninstalling the application or clearing its application data may remove locally stored preferences.

6. No Advertising or User Tracking

RaviGauge is provided free of charge.

The application:

• Does not display advertisements.

• Does not contain paid subscriptions.

• Does not require in-app purchases.

• Does not use advertising-based user profiling.

• Does not intentionally track users across applications or websites.

• Does not intentionally sell or rent personal information.

• Does not require registration or account authentication.

The documented application configuration does not include Firebase-based user accounts or automatic exercise uploads.

AFO does not use the exercise photographs or annotations for advertising.

7. Third-Party Applications and External Links

Certain optional functions may allow users to open external communication applications, such as WhatsApp or an email application, to contact AFO.

These functions are initiated by the user.

When a user opens an external application or website, that service operates under its own privacy policy, terms and data-handling practices.

AFO does not control the independent privacy practices of third-party application providers.

Users should review the privacy policies of those services before providing personal information through them.

8. Information Not Intentionally Collected

Under the documented application design, RaviGauge does not intentionally collect or transmit:

• Names or personal profiles.

• Email addresses for registration.

• Telephone numbers for registration.

• Passwords or authentication credentials.

• Contact lists.

• Location information.

• Microphone or voice recordings.

• Patient medical records.

• Payment information.

• Captured training photographs.

• Exercise annotation files.

The application does not provide a cloud account or online student database.

This statement concerns information handled by the application itself and does not override information independently processed by the device operating system, app-store provider or external applications.

9. Data Security

AFO follows a data-minimisation approach in the design of RaviGauge.

Exercise images and annotations are processed locally rather than being routinely transmitted to AFO servers.

Users remain responsible for maintaining the security of their devices, operating-system permissions and any external applications they choose to use.

No electronic system or mobile device can be guaranteed to be completely secure. AFO therefore cannot warrant absolute security against every possible technical failure, unauthorised device access or security incident.

10. Data Retention and Deletion

RaviGauge is not designed as a permanent exercise-record storage system.

Captured images and annotation information are temporary and are not intended to remain available as saved exercise files.

The limited AFO prompt-completion preference remains locally stored until the application data is cleared or the application is uninstalled.

Since the documented application does not maintain user accounts or a central exercise database, there is no online user account or exercise archive to request deletion from.

Users may uninstall the application or clear its application data through their device settings.

11. Children's Privacy

RaviGauge is an educational application intended primarily for dental students, dental professionals and adult learners.

It is not specifically designed or marketed as a children's application.

AFO does not intentionally collect personal information from children through the documented application functionality.

12. Educational Disclaimer and Limitation of Responsibility

RaviGauge is provided solely as a free educational and simulation resource.

It is not a medical device, diagnostic instrument, clinical measurement system or substitute for professional education, supervision, clinical judgement or established orthodontic procedures.

The application uses user-adjustable visual overlays and configured comparison limits. Its Smart Guide provides a geometric starting suggestion and does not independently establish the correct anatomical landmark.

The Live View overlay is screen-fixed and does not automatically detect or track individual teeth. Visual alignment does not establish accurate three-dimensional positioning.

The visual ruler is an uncalibrated comparison guide and does not represent millimetres or provide validated physical measurements.

Green, yellow, red or other feedback indicators represent application-defined comparisons only. They do not certify the physical position, orientation or clinical correctness of an orthodontic bracket.

Users are solely responsible for using the application within its stated educational and simulation scope.

To the maximum extent permitted by applicable law, AFO, its director, faculty, educational coordinators and associated centres disclaim responsibility for decisions, actions, losses or damages arising from misuse of the application, reliance on its visual feedback, unauthorised clinical use, device malfunction or use outside its intended educational purpose.

Nothing in this policy excludes liability that cannot lawfully be excluded under applicable law.

13. Changes to This Privacy Policy

AFO may update this Privacy Policy when application functionality, technical implementation, legal requirements or privacy practices change.

The revised policy will be published through the official AFO website. Users are encouraged to review it periodically.

Material changes to data-handling practices will be reflected in the updated policy and relevant app-store disclosures.
