Privacy Policy

Last Updated: September 30, 2025

At SpectraCheck, we are committed to protecting your privacy and ensuring transparency about how we handle your data. This Privacy Policy explains our data practices when you use our color vision accessibility testing tool.

Your Privacy Matters

SpectraCheck is designed with privacy as a core principle. We believe in transparency and giving you control over your data.

Key Privacy Commitment:

All image processing happens entirely in your browser. Your images are never uploaded to our servers, stored, or transmitted anywhere.

Information We Collect

1. Images You Upload

Collection: When you upload an image for color vision deficiency (CVD) simulation, the image is processed entirely in your browser using client-side JavaScript and WebGL.

Storage: We do not store, transmit, or have access to any images you upload. All processing is local to your device.

Retention: Images remain in your browser's memory only while you're actively using the tool. When you close the browser tab or navigate away, the images are immediately cleared from memory.

2. Analytics Data

We use Google Analytics to understand how visitors use our website. This helps us improve the tool and provide better content. The information collected includes:

  • Pages visited and time spent on each page
  • Browser type and version
  • Device type (desktop, mobile, tablet)
  • Geographic location (country/city level only)
  • Referring website (where you came from)
  • Operating system

Note: Analytics data is anonymized and aggregated. We cannot identify individual users from this data.

3. Contact Form Data

When you submit our contact form, we collect:

  • Your name
  • Email address
  • Subject of your inquiry
  • Message content

This information is used solely to respond to your inquiry and is not shared with third parties or used for marketing purposes without your explicit consent.

4. Cookies and Local Storage

We use minimal cookies and browser storage:

  • Analytics Cookies: Google Analytics sets cookies to track your session and distinguish unique visitors.
  • Preference Cookies: We may store your UI preferences (e.g., selected CVD type, severity level) in local storage to improve your experience on return visits.

How We Use Your Information

We use the information we collect for the following purposes:

  • Provide the Service: Enable CVD simulation and image analysis entirely in your browser
  • Improve the Tool: Analyze usage patterns to enhance features and user experience
  • Respond to Inquiries: Answer questions and provide support via contact form submissions
  • Create Educational Content: Develop blog articles and resources based on common questions and needs (no personal information is used)
  • Monitor Performance: Track page load times and errors to ensure optimal performance

Data Security

We take data security seriously:

  • HTTPS Encryption: All data transmitted between your browser and our website is encrypted using SSL/TLS
  • No Server-Side Image Storage: Since images are processed client-side, they never touch our servers
  • Secure Contact Form: Contact submissions are transmitted securely and stored with encryption
  • Regular Security Audits: We conduct regular security reviews of our codebase and infrastructure
  • Limited Data Collection: We only collect data that is necessary for the service to function

Third-Party Services

We use the following third-party services:
