Privacy Policy
Last updated: 2026-06-07
1. Overview
This application provides a client-side interface for managing orthodontic and clinical image files stored locally in the browser or in third-party cloud storage services such as Microsoft OneDrive.
The application is designed with a client-first architecture. We do not operate a traditional backend storage system and do not host user files.
2. Data Storage Model
The application supports two storage modes:
Local Storage
- Files and related data are stored locally in the user's browser (e.g. local storage or IndexedDB)
- Data never leaves the user's device unless explicitly uploaded to a connected cloud provider
Cloud Storage (BYOS)
- The application integrates with third-party storage providers such as Microsoft OneDrive via Microsoft Graph API
- Files remain in the user's own storage account and are not copied or stored by us
3. Data We Do Not Store
We do not permanently store:
- Images, photos, or medical records
- Patient data or clinical files
- File contents from local or cloud storage
- Directory structures or file metadata
- IP addresses or device identifiers
- User activity logs
4. Server-side Processing (Transient Data Handling)
While the application is primarily client-side, limited server-side processing is used to enable integration with Microsoft OneDrive.
When cloud features are used, our backend may temporarily process the following data:
- File and folder names (which may include personal data such as patient names)
- Directory structure information from OneDrive
- Operational commands such as listing folders, renaming files, deleting files, and file management actions
This data is:
- Processed only in memory
- Not stored in any database or persistent storage
- Discarded immediately after the request is completed
5. Authentication & Access Tokens
When connecting to Microsoft OneDrive:
- Authentication is handled via Microsoft OAuth and Azure App permissions
- Access tokens are used only during active sessions
- Tokens are not stored on our servers
6. Third-Party Services
The application integrates with third-party services, including:
- Microsoft OneDrive (via Microsoft Graph API)
Your use of third-party services is governed by their respective privacy policies:
We are not responsible for data handling practices of third-party providers.
7. Security
We apply standard security practices to protect communication between the client, backend relay services, and third-party APIs.
However, no system can guarantee absolute security, and users are responsible for securing their own accounts and devices.
8. Data Processing Role
We act as a technical intermediary facilitating user interactions with external storage providers. We do not control or own user data stored in third-party systems.
9. Changes to This Policy
We may update this Privacy Policy from time to time. Continued use of the application constitutes acceptance of the updated version.
