Data Flow & Privacy

OpenJung is privacy-first. Tests run in your browser and we only store anonymous, research-grade records needed for aggregate statistics.

At a glance

  • No accounts, names, emails, or phone numbers.
  • Results are computed in your browser.
  • We store anonymized test records for aggregate stats and research.
  • Personal dashboard data stays in your browser.

Website test flow

1) Your browser

Questions render client-side. Answers stay on your device while you take the test.

↓

2) /api/record

When you finish, the browser sends an anonymized record (answers, derived scores, locale, timestamps).

↓

3) D1 database

Records are stored for aggregate statistics and research. No personal identifiers.

API data paths

  • /api/calculate returns results immediately. If save=false, nothing is stored.
  • /api/calculate with save=true stores the same anonymized fields and returns a record ID.
  • /api/session stores session answers server-side until completion, then saves the final anonymized record.
  • /api/record stores a completed anonymized record sent by the client.

Research & statistics

Aggregate endpoints and research downloads are generated from anonymized records. Exports include type, dimension scores, locale, and completion month only.

/api/stats /api/research/stats /api/research/download

Analytics & infrastructure

  • Google Analytics: collects usage events like pageviews and feature usage and may set analytics cookies. You can block it with privacy tools.
  • Cloudflare: provides CDN, hosting, and security. It may process IP addresses and request metadata in standard logs.

Your controls

  • Use save=false when calling the API to avoid storage.
  • Clear local browser data to remove history, journals, and preferences.
  • Block analytics with browser settings or privacy extensions.
