Privacy Policy

Last updated: 2026-05-03

1. About This Privacy Policy

This Privacy Policy explains how ColorBlind Sim ("we", "us", or "our"), accessible at color-blindness-simulator.hub2.day, collects, uses, and shares information when you use our color vision deficiency simulation tool. We are committed to protecting your privacy and being transparent about our practices.

2. Information We Process

2.1 Browser-Local Tool Inputs

Our core simulation tool processes colors and images entirely within your browser. Any colors you select, images you upload, or settings you adjust are processed locally on your device and are not transmitted to our servers. We do not see, collect, or store the visual content you test.

2.2 Contact Email

If you choose to contact us at hello@color-blindness-simulator.hub2.day, we will receive your email address and any information you include in your message. We use this information solely to respond to your inquiry and provide support. We retain correspondence for up to 12 months for quality and reference purposes, after which it is securely deleted.

2.3 Server and Security Logs

Our web servers automatically record standard technical information when you visit, including your IP address, browser type, referring pages, and timestamps. These logs are retained for a maximum of 30 days and are used exclusively for security monitoring, troubleshooting, and maintaining service availability. They are not combined with any other data for profiling or tracking.

2.4 Cookies and Local Storage

We use a minimal amount of local storage and essential cookies to remember your simulation preferences (such as selected deficiency type) during your visit. These are strictly necessary for the tool to function and do not track you across sessions or websites. No personal information is stored in these mechanisms.

3. Advertising and Third-Party Services

3.1 Google AdSense

We display advertisements through Google AdSense, which uses cookies and similar technologies to serve ads based on your prior visits to this site or other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your browsing activity. You may opt out of personalized advertising by visiting Google Ads Settings or www.aboutads.info.

3.2 GDPR, EEA, and UK Consent

If you are located in the European Economic Area (EEA) or the United Kingdom, we request your consent before non-essential cookies and personalized ads are loaded, in accordance with the General Data Protection Regulation (GDPR) and the UK GDPR. You can withdraw your consent at any time by clearing your browser cookies and reloading the site to see the consent prompt again.

3.3 CCPA/CPRA Choices

Under the California Consumer Privacy Act (CCPA) and the California Privacy Rights Act (CPRA), California residents have the right to opt out of the "sale" or "sharing" of personal information. Google AdSense may use data for personalized advertising in ways that could be considered a sale or sharing under these laws. You can exercise your right to opt out by using the "Do Not Sell or Share My Personal Information" link available through our consent management platform, or by configuring your browser to send a Global Privacy Control (GPC) signal.

4. Service Providers

We engage trusted third-party service providers to assist with website hosting, security, and email delivery. These providers are contractually bound to process data only on our instructions and to implement appropriate security measures. No tool-input data is shared with them.

5. Data Retention

We retain server logs for 30 days and contact correspondence for 12 months. Local storage and essential cookies persist only for the duration of your browser session or until you clear them. Google AdSense data retention is governed by Google's own policies.

6. Children's Privacy

Our service is not directed to individuals under the age of 16. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us immediately so we can remove it.

7. Security

We implement industry-standard technical and organizational measures to protect the limited data we process. However, no method of electronic transmission or storage is 100% secure. We cannot guarantee absolute security.

8. Third-Party Links

Our site may contain links to external resources or advertisements. We are not responsible for the privacy practices or content of those third-party sites. We encourage you to review their policies.

9. International Data Processing

Our servers are located in the United States. If you access our site from outside the U.S., your information may be transferred to, stored, and processed in the U.S. By using the service, you consent to such transfer. We take steps to ensure adequate protection for data transferred internationally where required by law.

10. Your Rights and Contact

Depending on your jurisdiction, you may have rights regarding access, correction, deletion, or portability of your personal data. To exercise these rights, or if you have questions about this policy, please contact us at hello@color-blindness-simulator.hub2.day. We will respond within the timeframe required by applicable law.
