Last Updated: May 27, 2026

Arcanum Labs ("we," "us," or "our") operates the Chromatica mobile application (the "App"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our App.

Contact Information

1. Information We Collect

1.1 Information You Provide

Chromatica is designed with privacy in mind. All your personal game data is stored locally on your device only and is never transmitted to our servers. This includes:

  • Current puzzle state and game progress
  • Tier progression and level completion history
  • Settings and preferences (theme, accessibility, sound, haptics, colourblind mode)
  • Hint usage data (stored locally to track which hints you've seen)

No user accounts are required. Chromatica does not collect your name, email address, phone number, or any other personally identifiable information (PII).

1.2 Automatically Collected Information

When you use Chromatica, certain information may be automatically collected by third-party services integrated into the App:

Firebase Analytics (when enabled)

If you have analytics enabled (configurable in Settings), the following usage events are collected:

  • Game Lifecycle: Puzzle started, completed, failed, hint used, tier advanced (including tier and level identifiers)
  • Session Data: Total puzzles solved, current tier and level, session duration
  • Settings Changes: Setting name and value when changed, settings reset
  • User Properties: Current tier and level (aggregate, non-identifying)

You can disable analytics collection at any time via Settings → Data & Privacy → Analytics. When disabled, no analytics events are sent to Firebase.

Firebase Crashlytics

Crash reports and error logs are collected automatically in release builds to help us identify and fix bugs. This includes:

  • Stack traces and error messages
  • Device model and operating system version
  • App version and build number
  • Environment identifier (development/production)

Crash reporting is disabled in debug/development builds.

Device Information

  • App version (displayed in the About page)
  • Locally generated UUIDs for game state (app-local identifiers, not device identifiers)

We do not directly collect device model, manufacturer, operating system version, or hardware identifiers. However, third-party SDKs (Firebase, AdMob) may collect such information as described below.

1.3 Third-Party Services

Chromatica integrates the following third-party services that may collect information:

You can choose to enable personalized ads at any time via Settings → Data → Privacy Options, in compliance with the ePrivacy Directive and GDPR.
  • Privacy Policy: https://policies.google.com/privacy
  • Opt-Out: You can review or change your consent choice at any time via Settings → Data → Privacy Options. You may also manage your Advertising ID through your device settings.

Firebase Analytics

  • Purpose: To understand app usage patterns and improve the user experience
  • Data Collected: Usage events (as described in Section 1.2), session data, device metadata
