Privacy Policy
Last Updated: September 11, 2026
This Privacy Policy explains which data stays in your browser and which technical, analytics, and advertising data may be processed by third-party services used on this site.
1. Information Collection
Test responses and history are stored locally in your browser. When you use the site, Google Analytics, Microsoft Clarity, and our advertising partner Journey by Mediavine may process technical, usage, and advertising data such as IP address, browser and device information, cookie or similar identifiers, pages viewed, and interactions. We do not ask you to create an account or enter your name for the tests.
2. Information Use
Local test data is used to display results and history on your device. Third-party services may use the data they receive to measure site usage, maintain security, improve services, select or measure advertising, and meet their own legal obligations, subject to their policies and your available choices.
3. Data Storage
Your test history is stored in browser local storage and is not uploaded to a Stroop Test account or profile. Analytics and advertising providers may separately process and retain technical, usage, cookie, and identifier data on their systems according to their own retention practices.
4. Data Security
We use HTTPS and reasonable technical measures to protect the site. No internet transmission or storage method is completely secure, and third-party providers are responsible for protecting data they process under their own policies.
5. Cookie Usage
We use browser storage for necessary preferences and test history. Optional analytics technologies may be used for Google Analytics and Microsoft Clarity, and Journey by Mediavine and its advertising partners may use cookies, web beacons, IP addresses, or other identifiers to serve and measure advertising. Availability of consent and opt-out choices can depend on your region.
6. Third-Party Services
The site uses Google Analytics, Microsoft Clarity, and Journey by Mediavine for advertising. These providers, including Mediavine advertising partners, may collect or receive data through their scripts, cookies, web beacons, and requests, and may process it under their own privacy policies. The site may also link to other third-party websites.
7. Children's Privacy
Our service is not directed to children under 13, and we do not ask children to create accounts or submit names through the tests. If you believe a child has provided personal information through another channel, please contact us.
8. Your Rights
You can view, export, or delete locally stored test history using the site controls or your browser settings. Depending on your location, you may also have rights or choices concerning analytics and advertising data processed by third parties. Contact us for privacy questions and use the applicable provider or consent controls for those services.
9. Advertising Partner
This site works with Journey by Mediavine to display advertising. Mediavine’s required advertising disclosure is reproduced below.
Mediavine Programmatic Advertising (Ver 1.1)
The Website works with Mediavine to manage third-party interest-based advertising appearing on the Website. Mediavine serves content and advertisements when you visit the Website, which may use first and third-party cookies. A cookie is a small text file which is sent to your computer or mobile device (referred to in this policy as a “device”) by the web server so that a website can remember some information about your browsing activity on the Website.
First party cookies are created by the website that you are visiting. A third-party cookie is frequently used in behavioral advertising and analytics and is created by a domain other than the website you are visiting. Third-party cookies, tags, pixels, beacons and other similar technologies (collectively, “Tags”) may be placed on the Website to monitor interaction with advertising content and to target and optimize advertising. Each internet browser has functionality so that you can block both first and third-party cookies and clear your browser’s cache. The "help" feature of the menu bar on most browsers will tell you how to stop accepting new cookies, how to receive notification of new cookies, how to disable existing cookies and how to clear your browser’s cache. For more information about cookies and how to disable them, you can consult the information at All About Cookies.
Without cookies you may not be able to take full advantage of the Website content and features. Please note that rejecting cookies does not mean that you will no longer see ads when you visit our Site. In the event you opt-out, you will still see non-personalized advertisements on the Website.
The Website collects the following data using a cookie when serving personalized ads:
- IP Address
- Operating System type
- Operating System version
- Device Type
- Language of the website
- Web browser type
- Email (in hashed form)
Mediavine Partners (companies listed below with whom Mediavine shares data) may also use this data to link to other end user information the partner has independently collected to deliver targeted advertisements. Mediavine Partners may also separately collect data about end users from other sources, such as advertising IDs or pixels, and link that data to data collected from Mediavine publishers in order to provide interest-based advertising across your online experience, including devices, browsers and apps. This data includes usage data, cookie information, device information, information about interactions between users and advertisements and websites, geolocation data, traffic data, and information about a visitor’s referral source to a particular website. Mediavine Partners may also create unique IDs to create audience segments, which are used to provide targeted advertising.
If you would like more information about this practice and to know your choices to opt-in or opt-out of this data collection, please visit National Advertising Initiative opt out page. You may also visit Digital Advertising Alliance website and Network Advertising Initiative website to learn more information about interest-based advertising. You may download the AppChoices app at Digital Advertising Alliance’s AppChoices app to opt out in connection with mobile apps, or use the platform controls on your mobile device to opt out.
