Privacy Policy for ColorBlindTest

Effective date: 2026-07-22

Introduction

ColorBlindTest ("we", "us") operates the color vision screening website at color-blind-test.org. We respect your privacy. This policy explains what we collect, how we use it, and your choices. Our service is for educational screening only and is not a medical diagnosis.

What We Collect

• Test usage data: the test selected, answers, response times, completion time, calculated result, and a random result identifier.
• Device/technical data: browser user agent and basic screen information (dimensions, color depth, and pixel ratio). Hosting and security providers may also process information normally sent with web requests, such as an IP address.
• Optional analytics/cookies: essential cookies for preferences; optional analytics may help improve the product.
• Result links: completing a test creates a random, unlisted result link when database storage is available. Anyone who obtains the link can view the result, so do not include or share information you consider sensitive.

We do not require registration to take the test. You can use the service anonymously.

How We Use Data

• Provide and improve the test experience and site reliability.
• Generate and display your screening result and related explanations.
• Prevent abuse, maintain security, and comply with legal duties.

Data Retention

• Session data is kept for the duration of your visit.
• Stored results are retained as needed to provide result links and operate the service. You may request deletion by sending us the result URL.

Cookies

We use essential cookies for site functionality (e.g., locale, UI state). Optional analytics cookies, if enabled, help us understand usage. You can control cookies in your browser settings.

Sharing

We do not sell personal data. We may share limited data with service providers under confidentiality to operate the site, or when required by law.

Your Choices

• Use the test without creating an account.
• Opt out of non‑essential cookies/analytics (where presented).
• Request deletion of a stored result by emailing the result URL to us.

Changes

We may update this policy. Material changes will be posted here with an updated effective date.
