The Service collects detailed psychometric and cognitive performance information.

3.5 Sensitive Assessment Data; special category data; "sensitive personal information"

Assessment Data is sensitive in context because it can reveal intimate aspects of personality and cognitive performance. Depending on the questions asked and your responses, Assessment Data may also reveal or allow inferences about "special category" data (EEA/UK/Switzerland) or "sensitive personal information" (certain U.S. state laws).

We may disclose information where required by law or necessary to protect rights, prevent fraud, or protect users and the public.

7) Admin Access to Identifiable Assessment Data

The Service provides access to individual results and, where you choose to share, comparison results through the user interface. Authorized Haystack personnel may access identifiable Assessment Data (including responses, outputs, and registration information) to operate the Service, provide support, and respond to requests. Access is restricted and governed by internal controls.

8) Profiling; Automated Processing

We use automated processing to score assessments, generate psychometric outputs, and create inferences and profiles. Where required by law, we will provide additional disclosures and rights relating to profiling and automated decision-making.

9) Cookies; Tracking; Interest-Based Advertising

We may use cookies, SDKs, pixels, and similar technologies for:

  • essential operation and security
  • analytics and performance measurement
  • advertising, including interest-based advertising (where permitted)

Where required by law (including in the EU/EEA/UK), we request consent for non-essential cookies before they are placed.

We are based in the United States. Your information may be processed in the United States and other countries where we or our vendors and partners operate. Where required, we use appropriate safeguards for cross-border transfers (e.g., Standard Contractual Clauses and supplementary measures).

11) Data Retention

11.1 Retention criteria

We retain personal information for as long as reasonably necessary for the purposes described in this Policy. Because our purposes include maintaining assessment records, supporting results access, validating psychometric methods, and improving the Service, retention may be long-term while those purposes continue, subject to legal requirements and periodic review.

We may irreversibly de-identify/anonymize or aggregate information. De-identified/anonymized or aggregated information may be retained indefinitely and used for any lawful purpose.
