Privacy Policy
How ADHD screening responses, analytics, and ads are handled
Last updated: October 2025
ADHD Test Online is designed so your screening answers stay on your device. This policy explains that local-processing model, along with the third-party analytics and advertising services used on the site.
No Server Storage for ADHD Screening Answers
Your ADHD test responses and results are processed in your browser and are not stored on our servers. When you complete an ADHD test, your answers and results remain on your device through browser local storage. We do not have access to your screening answers and cannot view your test results.
How Local Processing Works
When you take an ADHD screening test on our platform, all scoring calculations happen in your browser using JavaScript. Your responses are temporarily stored in your browser's local storage so progress and results can work on your device. If you clear your browser data or use private/incognito mode, your test progress may be deleted from your device.
Website Analytics
We use website analytics to understand page performance, usage patterns, and technical issues. Analytics may include information such as pages viewed, device/browser information, referrer, approximate region, and timestamps. We do not connect analytics data to ADHD screening answers or results.
Cookies, Local Storage, and Advertising
The ADHD test itself uses browser local storage for progress and results. The site may also load third-party analytics and Adsterra advertising scripts, which can use cookies or similar technologies according to their own policies. You can control cookies and site storage in your browser settings, though disabling storage may affect test progress.
Third-Party Services
We do not sell ADHD screening answers or results. We do use third-party services for hosting, analytics, and Adsterra advertising. These providers may process technical data needed to deliver, measure, secure, or monetize the website. They do not receive your locally stored ADHD test answers from us.
Privacy Rights
Because ADHD screening answers are stored locally, there are no screening responses for us to retrieve, correct, or delete from our servers. Depending on your location, you may have rights related to personal data processed by analytics, advertising, or infrastructure providers. Contact us if you have a privacy request and we will explain what data we can reasonably access.
Children's Privacy
Our Child ADHD Screening Test (SNAP-IV) is designed for parents, teachers, and caregivers to assess children's ADHD symptoms. We do not knowingly collect personal information from children under 13. The child screening tool follows the same privacy-first architecture—all responses are processed locally and never transmitted to our servers. Parents and caregivers maintain complete control over screening data on their own devices.
Data Security Measures
While we don't store ADHD screening data, we implement industry-standard security measures for our website infrastructure. This includes HTTPS encryption for all pages, secure hosting, regular security updates, and protection against common web vulnerabilities. Your browser's local storage is protected by same-origin policy, meaning only our website can access data stored by our site. We recommend using updated browsers and keeping your devices secure to protect locally stored ADHD test data.
Your Privacy Rights and Control
You have complete control over your ADHD screening data because it's stored only on your device. You can delete your test results at any time by clearing your browser's local storage or using your browser's privacy settings. You can take screenshots or print your results for your records or to share with healthcare providers—this is entirely your choice. If you have questions about how your data is handled, contact us and we'll provide detailed technical explanations.
Changes to This Privacy Policy
We may update this privacy policy to reflect changes in our practices, technology, or legal requirements. Any significant changes will be prominently posted on our website with an updated 'Last Updated' date. We will never change our core commitment to privacy-first ADHD screening. If we ever consider collecting ADHD test data (which we have no plans to do), we would notify users clearly and obtain explicit consent.
