How NIDA Collects Information
NIDA web sites use Google Analytics measurement software to collect the information in the bulleted list in the Types of Information Collected section above. Google Analytics collects information automatically and continuously. No personally identifiable information is collected. The NIDA staff conducts analyses and reports on the aggregated data from Google Analytics. The reports are only available to NIDA web staff, and other designated staff who require this information to perform their duties.
Information submitted through contact forms, including the NIDA Feedback Form or the Proposal Intent Response Sheet, is also collected by NIDA. This information is additionally processed by the anti-spam modules Honeypot and reCAPTCHA.
NIDA retains this data as long as needed to support the mission of the NIDA web sites.
