Cookies are small text files that websites place on your device to remember information about your visit. At Quelithon Zen, we use cookies and similar technologies to make our investment education platform work better for you.

Think of cookies like bookmarks in a book – they help us remember where you left off and what you found useful. When you visit our site, these tiny files help us recognize your browser and provide a more personalized learning experience.

Beyond traditional cookies, we also use web beacons, pixel tags, and local storage technologies. These tools help us understand how people use our educational content and identify areas where we can improve the learning experience.

Our analytics show that students who engage with personalized content have better learning outcomes. That's why we collect data about which lessons you find most valuable and where you might need additional support.

We also track technical information like your device type, browser version, and screen resolution. This helps us ensure our platform works smoothly across different technologies and identify compatibility issues quickly.

You have complete control over most cookies and tracking technologies. Here's how you can manage your preferences and protect your privacy while still accessing our educational content.

1. Browser Settings: Most browsers allow you to view, delete, and block cookies. Look for "Privacy" or "Security" settings in your browser menu. You can set your browser to notify you when cookies are being placed.
2. Our Preference Center: Visit our cookie preference center to choose which types of cookies you want to allow. You can change these settings at any time, and your choices will be remembered.
3. Third-Party Opt-Outs: For analytics and advertising cookies from third parties, you may need to opt out directly with those companies. We provide links to major opt-out tools and services.
4. Mobile Devices: Smartphones and tablets have their own privacy controls. Check your device settings for options like "Limit Ad Tracking" on iOS or "Opt out of Ads Personalization" on Android.

If you're using a shared computer, consider using private or incognito browsing mode. This prevents cookies from being stored permanently and protects your privacy when using public devices.

We don't keep your data forever. Different types of information have different retention periods based on their purpose and legal requirements. Here's what happens to your data over time.

Session cookies are deleted when you close your browser. Persistent cookies typically last between 30 days and 24 months, depending on their function. Analytics data is usually retained for two years to help us understand long-term trends in education effectiveness.

You can request a copy of the personal data we hold about you, ask us to correct inaccurate information, or request deletion of your data. These rights are protected under privacy laws, and we respond to requests within 30 days.

We regularly review our data retention policies to ensure we're only keeping information as long as necessary. When data reaches the end of its retention period, it's securely deleted from our systems.

This policy is effective as of January 2025 and will be reviewed annually to ensure it remains current with changing technology and legal requirements. We'll notify users of any significant changes through email or website announcements.
