Privacy Policy
Complete privacy for your ADHD screening
Last updated: October 2025
At ADHD Test Online, your privacy isn't just a priority—it's fundamental to how our service works. This policy explains our privacy-first approach to ADHD screening and how we protect your sensitive health information.
Zero Data Collection for ADHD Screening
Your ADHD test responses and results are never collected, transmitted, or stored on our servers. Period. All ADHD screening assessments are processed entirely within your web browser using local storage. When you complete an ADHD test, your answers and results remain exclusively on your device. We have no access to your screening data, and we cannot see your ADHD test results. This architecture ensures complete confidentiality for your mental health information.
How Local Processing Works
When you take an ADHD screening test on our platform, all calculations happen in your browser using JavaScript. Your responses are temporarily stored in your browser's local storage—a secure area on your device that only you can access. No ADHD test data ever leaves your computer, phone, or tablet. If you clear your browser data or use private/incognito mode, your test progress will be deleted from your device. This is by design to protect your privacy.
Anonymous Website Analytics
We collect minimal, anonymous analytics to understand how visitors use our ADHD screening platform. This includes aggregate data like page views, time spent on pages, and which ADHD test (adult or child) is more popular. We use privacy-focused analytics tools that do not track individual users or create personal profiles. This anonymous data helps us improve the user experience and identify technical issues. We never connect analytics data to ADHD test responses or results.
Essential Cookies Only
We use only essential cookies required for the website to function properly, such as remembering your language preference (English or Spanish) and maintaining your session. We do not use advertising cookies, tracking cookies, or third-party marketing cookies. You can control cookie settings in your browser, though disabling essential cookies may affect website functionality. Your ADHD test progress is saved using browser local storage, not cookies, providing an additional layer of privacy.
No Third-Party Data Sharing
We do not sell, rent, trade, or share any user data with third parties for marketing purposes. We do not share ADHD screening data with advertisers, data brokers, or other companies. The only third-party services we use are essential infrastructure providers (web hosting, content delivery) that do not have access to ADHD test responses. We do not integrate with social media tracking pixels or advertising networks.
GDPR and International Privacy Compliance
Our privacy-first architecture complies with the General Data Protection Regulation (GDPR), California Consumer Privacy Act (CCPA), and other international privacy laws. Since we don't collect ADHD screening data, there's no personal health information to access, correct, or delete from our servers. Your data rights are protected by design—your ADHD test data never leaves your device. If you're in the European Union or other regions with strict privacy laws, you can use our service with confidence knowing your health information stays private.
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.
