Privacy Policy

Your privacy matters. We collect limited, anonymous data to improve the test and publish aggregate stats. We never sell or share personal info.

Last updated: January 18, 2026

Overview

OpenJung is committed to protecting your privacy. This policy explains what we collect, how we use it, and your rights regarding your data. We focus on anonymous test data and minimal analytics, not personal identifiers.

What We Collect

We follow a privacy-first approach and collect only what we need to run the service and improve the test:

  • ✓ Anonymous test responses and derived scores (type, dimension scores, locale, timestamps)
  • ✓ Basic usage analytics events (pageviews and feature usage) via Google Analytics
  • ✗ No names, emails, phone numbers, or account registration
  • ✗ No advertising or retargeting cookies
  • ✗ We do not store IP addresses in our application database
  • ✗ No browser fingerprinting or data sales

How We Use Data

The anonymous data we collect is used solely for:

  • Improving test quality and question reliability
  • Generating aggregate statistics about personality type distributions
  • Research to enhance the assessment methodology

Data Storage

Website results are computed in your browser. We send an anonymized record (answers, derived scores, locale, timestamps) to our database to power aggregate statistics and research. API endpoints that create sessions or set save=true also store the same fields. Personal dashboard data (history, journal, bookmarks, goals, preferences) stays in your browser.

Our infrastructure runs on Cloudflare (Workers + D1) with globally distributed servers.

Data Flow

Third-Party Services

We use the following third-party services:

  • Cloudflare: Provides hosting, CDN, and security services and may process IP addresses and request metadata in standard logs.
  • Google Analytics: Collects anonymized usage metrics and may set analytics cookies. You can block it with browser settings or privacy extensions.

Your Rights

You have the right to:

  • Take the test without creating an account or providing personal information
  • Clear your local browser data at any time to remove any stored preferences
  • Contact us with any privacy concerns or questions

Open Source Transparency

OpenJung is fully open source. You can review our code to see exactly how we handle data. We believe in building trust through transparency.
