Privacy Policy

Last updated: April 5, 2026

Overview

NodusNexus ("we", "our", "the game") is committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights.

Data We Collect

Local Storage Data

The game stores the following data locally on your device using browser localStorage. This data never leaves your device unless you explicitly choose to create an account:

  • Game settings (theme preferences, sound settings, helper toggles)
  • Game statistics (scores, win/loss records, achievements)
  • Daily challenge history and streaks
  • Tutorial completion status

Analytics Data (Optional)

We use PostHog for anonymous analytics to understand how the game is used and improve the experience. Analytics data includes:

  • Game events (start, end, mode selected) — no personal information
  • Device type and browser (aggregated, not individually identifying)
  • Error reports for debugging

Analytics are anonymous by default. We do not use cookies for tracking. No personal information is collected unless you create an account.

Multiplayer Data

When using multiplayer features, the following data is temporarily processed on our servers during the game session:

  • Display name you choose when creating or joining a room
  • Game moves and scores during the active session
  • Connection status for reconnection handling

Multiplayer session data is held in memory only and is not persisted to disk. It is automatically deleted when the room closes or after 30 minutes of inactivity.

Data We Do NOT Collect

  • Email addresses (unless you create an account)
  • Real names
  • Location data
  • Advertising identifiers
  • Data from other apps or websites

Third-Party Services

Children's Privacy

NodusNexus does not knowingly collect personal information from children under 13. The game can be played without providing any personal information.

Your Rights

You can at any time:

  • Clear all local data by clearing your browser's localStorage for this site
  • Disable analytics by using a browser ad-blocker or privacy extension
  • Request deletion of any account data by contacting us

Changes to This Policy

We may update this policy from time to time. Changes will be posted on this page with an updated date.
