Privacy Notice

When you interact with the eligibility questionnaire, we may collect the following categories of information:

• Questionnaire responses, such as the U.S. state you select, the type of smartphone you use, your self-reported device usage, and your interest in participating in a research program.
• Technical information, such as your IP address, browser type, device type, operating system, referring URL, and general geographic location derived from your IP address.
• Usage information, such as pages viewed, time on page, and click activity, collected through standard web analytics and tracking technologies.

We do not ask for, and this Site does not intentionally collect, sensitive personal information such as government identifiers, financial account details, or health information.

We use information to:

• Present and operate the eligibility questionnaire;
• Determine whether to direct you to a third-party research program's official registration page;
• Measure the performance of our marketing and improve the Site;
• Detect, prevent, and address fraud, abuse, and technical issues; and
• Comply with applicable legal obligations.

We and our service providers use cookies, pixels, tags, and similar technologies to operate the Site, measure traffic, attribute referrals from advertising partners, and improve performance. You can control cookies through your browser settings. Disabling cookies may affect Site functionality.

We may share information with:

• Service providers that host the Site, provide analytics, or help us measure marketing performance;
• Advertising and affiliate partners, so that referrals from advertising campaigns can be attributed (typically through anonymous identifiers, not questionnaire answers);
• Third-party research programs, only if you choose to continue from this Site to their registration page — in which case the information you submit to them is governed by their privacy notice, not this one; and
• Authorities when required by law, subpoena, or to protect our rights or the safety of others.

We do not sell questionnaire responses to third parties for their independent marketing.

We retain information only as long as reasonably necessary for the purposes described in this Privacy Notice, to comply with our legal obligations, resolve disputes, and enforce our agreements.

Depending on where you live, you may have rights under applicable law to access, correct, delete, or restrict the processing of your personal information, or to opt out of certain uses. To exercise these rights, contact us using the details in the "Contact" section below. We will respond in accordance with applicable law.

You may also control interest-based advertising through industry tools such as the Digital Advertising Alliance's opt-out page and your device's advertising settings.

This Site is intended for adults located in the United States. We do not knowingly collect personal information from children under the age of 13.

We use commercially reasonable administrative, technical, and physical safeguards designed to protect information from unauthorized access, disclosure, alteration, and destruction. No method of transmission or storage is completely secure.

We may update this Privacy Notice from time to time. When we do, we will revise the "Effective Date" above. Continued use of the Site after changes take effect constitutes acceptance of the updated Notice.

If you have questions about this Privacy Notice or wish to exercise a privacy right, please contact the Site operator at privacy@example.com.
