Privacy Policy

This policy applies to https://nbti.dofun.fun/ and all related pages.

NBTI is currently a static site. Core test logic runs in the browser with no account system and no user database backend.

(1) Data generated by your use

Your answers, progress, result code, and interaction events used for product optimization.

(2) Device and browsing data

Browser type, device type, page path, and access timestamps for stability and analytics.

(3) Local storage data

We store progress, latest results, and lightweight event logs in LocalStorage to support continuity.

(1) To provide core functionality

Test flow, scoring, result rendering, share copy, and card download.

(2) To improve product experience

Analyze entry clicks, page engagement, and conversion patterns to improve structure and content.

(3) To maintain reliability and safety

Detect abnormal traffic and obvious abuse patterns to keep the site stable.

(1) Local-first storage

Your answers and latest result are stored in your browser. Clearing cache, switching device, or private mode may remove them.

(2) Retention window

Local event logs keep only a recent window and overwrite older records.

(3) Ranking data

Ranking reflects site-level sample distribution, not persistent personal identity tracking.

We may use cookies or local storage for basic functionality and performance optimization.

You can manage or disable these in browser settings, but some features (such as progress persistence) may be affected.

Some features may use third-party resources (for example, QR generation in share workflows).

Third-party services follow their own privacy terms. We prefer local assets where possible.

We do not sell personal data to unrelated third parties.

We may disclose necessary information only when legally required, for safety protection, or during lawful business restructuring under equivalent policy safeguards.

You can manage your data through browser controls:

1) View and clear LocalStorage data.

2) Manage cookies and tracking restrictions.

3) Stop using features that rely on local persistence.

NBTI is intended for general audiences. If you are a minor, please use the service under guardian guidance.

If guardians identify inappropriate submissions, they may contact us for assistance.

NBTI is a lightweight self-reflection and communication product, not a medical or clinical diagnostic tool.

Results are designed to explain current behavior patterns, not permanent or exclusive identity conclusions.

We may update this policy based on product, legal, or operational changes.

Updated versions will be published on this page with a revised "Last updated" date.

If you have questions about this policy or data handling, please contact us via channels published on the site.
