Data Usage Policy

Tracking technologies are small data files and scripts that websites use to remember information about your visits. At Crystech Arc, we use various tracking methods to enhance your learning experience and improve our AR development platform.

These technologies help us understand how you interact with our educational content, which features you find most valuable, and how we can better serve the AR development community in Vietnam and beyond.

When you're working through our AR development tutorials, tracking helps us remember where you left off in complex multi-part lessons. If you're learning Unity integration for mobile AR apps, we can save your progress through each coding exercise.

We also use this data to suggest relevant courses based on your current skill level. For instance, if you've completed our beginner ARCore tutorials, we might recommend our advanced spatial mapping workshops.

Performance tracking helps us identify when specific code examples or development environments are causing crashes or slow loading times, which is particularly important for AR applications that require real-time processing.

Most modern browsers allow you to control tracking technologies through their privacy settings. In Chrome, you can access these through Settings > Privacy and Security > Cookies and other site data.

Firefox users can find similar controls under Settings > Privacy & Security. Safari provides tracking protection through Preferences > Privacy.

• Block all third-party tracking while allowing essential site functionality
• Clear existing tracking data from specific websites or time periods
• Set automatic deletion schedules for tracking data
• Receive notifications when sites attempt to set new tracking technologies

Keep in mind that blocking all tracking may affect some features of our learning platform, particularly progress saving and personalized course recommendations.

Our platform integrates with several external services that may use their own tracking technologies:

Google Analytics helps us understand overall site usage patterns. YouTube integration for video tutorials may set their own tracking data. GitHub integration for code repositories may establish session tracking for seamless workflow.

We've configured these integrations to respect your privacy preferences where possible, but each service operates under its own privacy policy for data handling.
