1 Overview

ACIS (Advanced Comprehensive Intelligence Scale) is a web-based cognitive assessment. This Privacy Policy explains what information ACIS collects, how it is used, and your choices.

2 Information We Store Locally

ACIS uses browser storage (for example, localStorage) to store test progress and results on your device.

  • Test progress, scores, and completion timestamps
  • Local identifiers used to keep your session consistent (e.g., an anonymous user ID)

You can remove this local information by clearing your browser site data.

3 Information We May Store Server-Side (Supabase)

When the cloud sync feature is enabled, ACIS may transmit and store limited data in our backend database hosted on Supabase.

  • An anonymous user identifier (generated on-device or via anonymous authentication)
  • Demographic fields you provide: age, country, education level
  • If you enter an email address, ACIS stores a one-way hash of the email (not the email itself)
  • Test session data (e.g., test type, status, completion time)
  • Subtest and composite score data (e.g., raw/scaled scores, totals, response time)
  • Integrity/anti-cheat events (e.g., violation type and details)

4 Fingerprinting (Retake Detection)

ACIS uses browser fingerprinting to detect repeat attempts and protect test integrity. A fingerprint hash is generated on-device from multiple browser and device signals (e.g., canvas/WebGL/audio characteristics, installed font detection, and device info) and then hashed (SHA-256).

When cloud sync is enabled, ACIS may store the fingerprint hash server-side to detect retakes. ACIS does not need to store your raw fingerprint components in the database to perform this check.

5 Third-Party Services

  • Supabase: authentication and database hosting for cloud sync
  • PayPal: payment processing (payment details are handled by PayPal, not stored on ACIS servers)
  • CDNs: third-party script delivery (e.g., Supabase SDK)
  • Google Fonts: font delivery

6 Your Choices

  • You can clear locally stored data by clearing your browser site data.
  • If you want to request deletion of server-side data associated with your anonymous identifier, contact the creator via the details on the Terms of Service.
