Cookie Policy
Last Updated: February 15, 2025
This policy explains how cleverdataflow.com uses tracking technologies to enhance your learning experience. We believe in transparency about how data gets collected and used when you visit our blockchain education platform.
What Are Cookies
Cookies are small text files that websites place on your device. They help sites remember your preferences and understand how you interact with content. Most educational platforms use them—we're no different.
When you visit cleverdataflow.com, these files store information like your language preference or which lessons you've completed. Some cookies last only during your session, while others remain on your device for longer periods.
Types of Tracking We Use
Essential Cookies
These keep the platform running. Without them, you wouldn't be able to navigate between lessons or access your learning dashboard. We can't turn these off because they're fundamental to how the site works.
Functional Cookies
These remember your choices—like whether you prefer video explanations or written content. They make your experience feel personalized without collecting identifying information about who you are.
Analytics Cookies
We track which lessons get the most engagement and where learners typically get stuck. This data helps us improve course structure and identify content that needs clarification. The information is aggregated and anonymous.
Performance Cookies
These monitor how quickly pages load and whether certain features cause technical issues. When something breaks or runs slowly, these cookies help us diagnose and fix problems faster.
How We Use This Information
The data we collect serves specific purposes tied to improving blockchain education:
- Tracking your progress through beginner blockchain courses so you can pick up where you left off
- Understanding which teaching methods work better for different learning styles
- Identifying technical problems that affect the student experience
- Measuring how course updates impact completion rates and comprehension
- Preventing unauthorized access to student accounts and learning materials
We don't sell this data or share it with third parties for marketing. Our focus stays on educational improvement.
Some tracking technologies run continuously while you browse, but others only activate when you perform specific actions—like starting a quiz or downloading course materials.
Data Retention Periods
Different cookies have different lifespans based on their purpose. Session cookies disappear when you close your browser. Others might stick around for months or even a year.
Here's what typically happens:
- Login session data expires after 24 hours of inactivity
- Course progress tracking remains active for 18 months
- Performance monitoring data gets deleted after 90 days
- Preference settings last until you manually change them
You can clear all cookies at any time through your browser settings, though this might reset your preferences and progress tracking.
Managing Your Cookie Preferences
You control what tracking technologies your browser accepts. Most browsers let you block all cookies, though this might break certain platform features.
Each browser handles cookie management differently:
Chrome
Settings → Privacy and security → Cookies and other site data
Firefox
Settings → Privacy & Security → Cookies and Site Data
Safari
Preferences → Privacy → Manage Website Data
Edge
Settings → Cookies and site permissions → Manage cookies
If you block essential cookies, some parts of cleverdataflow.com won't function properly. The learning platform needs basic tracking to remember your login status and course progress.
Third-Party Tracking
We use analytics services to understand how students interact with blockchain concepts. These providers have their own privacy policies that govern how they handle data.
Currently, cleverdataflow.com works with analytics platforms that help us measure learning outcomes and identify areas where students struggle. These services collect anonymized usage patterns but don't receive personally identifiable information from us.
Third-party services can't access your course completion certificates or personal profile information. They only see aggregated behavior patterns across all users.
Your Rights and Choices
Beyond browser-level controls, you have specific rights regarding tracking data:
- Request information about what data we've collected through cookies
- Ask us to delete tracking data tied to your account
- Opt out of non-essential tracking while maintaining course access
- Export your learning progress data in a readable format
These requests might affect platform functionality. For example, opting out of functional cookies means we can't remember your display preferences between sessions.
Updates to This Policy
We update this policy when we introduce new tracking technologies or change how we use existing ones. Major changes get announced through email notifications to registered students.
The "Last Updated" date at the top reflects when we most recently modified this document. We recommend checking back periodically, especially before enrolling in new courses starting in autumn 2025.
