Privacy Policy

Last updated: July 2026

Data collection

We don't collect anything.

• No photos are uploaded or stored
• No measurements are saved or transmitted
• No user accounts or authentication
• No tracking cookies or analytics
• No third-party services

How the app works

ToothShader is a client-side only application:

1. You upload a photo or capture from your camera
2. The image stays in your browser's memory
3. Color analysis happens locally using JavaScript
4. Results are displayed instantly — nothing is sent anywhere

Camera access

When you use the Camera feature, the app requests access to your device's camera. This:

• Happens entirely in your browser
• Does not transmit video or photos to any server
• Is only used to capture a single still frame for analysis
• Stops immediately after you capture or exit camera mode

Photos you upload

When you choose a photo from your device:

• The file is read into your browser's memory only
• It is never uploaded to a remote server
• It is discarded when you refresh the page or close the tab

Browsing data

This website does not use:

• Cookies (except any essential cookies required by your hosting provider, if applicable)
• LocalStorage or SessionStorage for any personal data
• Any form of tracking or analytics
• Any third-party scripts or services

Server logs

If you host this on a static hosting service (GitHub Pages, Netlify, Vercel, etc.), that provider may log basic HTTP requests like:

• IP address
• Browser user agent
• Timestamp
• Requested URL

These logs are maintained by the hosting provider according to their own policies, not by this application. The application itself does not access or process these logs.

Changes to this policy

If this application ever adds features that involve data collection or transmission, this policy will be updated to reflect those changes. Given the current design, no such changes are anticipated.
