Cookie Policy
Last Updated: January 2025
WaveFlash uses tracking technologies on waveflash.dev to improve your experience and understand how you interact with our educational platform. This policy explains what these technologies are, how we use them, and your options for managing them.
What Are Cookies and Tracking Technologies
Cookies are small text files stored on your device when you visit our site. They help us remember your preferences and understand how you navigate through our educational content. We also use similar technologies like web beacons and local storage.
Think of cookies as bookmarks that remember where you left off in a course or what topics interest you most. They're not programs and can't carry viruses—they're just tiny pieces of data that make your learning experience smoother.
Types of Tracking We Use
Essential Cookies
These keep the site functioning properly. Without them, you wouldn't be able to log in, navigate between lessons, or access secure areas of our platform. We need these to operate waveflash.dev, so they're always active.
Functional Cookies
These remember your choices—like preferred language, dark mode settings, or which tutorials you've completed. They make your experience more personal without identifying you individually.
Analytics Cookies
We use these to understand which lessons are most helpful and where students get stuck. This data helps us create better educational content. All information is aggregated and anonymous.
Performance Cookies
These track page load times and technical performance. If a particular code example takes too long to display, we want to know about it so we can fix it.
How We Use These Technologies
Here's what actually happens with the data we collect:
- Track which encryption tutorials are most valuable to students
- Remember your progress through multi-part lessons
- Understand which code examples need better explanations
- Identify technical issues that affect your learning experience
- Personalize content recommendations based on your interests
- Measure how long students spend on different topics
- Test new features with small groups before wider release
Important: We don't sell your data to third parties. The information we collect stays within WaveFlash and helps us build better educational resources for the encryption programming community.

Managing Your Cookie Preferences
You have complete control over which cookies you accept. Most browsers let you block or delete cookies through their settings. Just know that blocking essential cookies will prevent the site from working properly.
Browser-Specific Instructions
Each browser handles cookies differently. Here's where to find the settings:
Google Chrome
support.google.com/chrome/answer/95647Mozilla Firefox
support.mozilla.org/kb/cookiesMicrosoft Edge
support.microsoft.com/edge/cookiesThird-Party Cookies
We occasionally embed content from other services—like video tutorials hosted on external platforms or interactive coding environments. These services may set their own cookies. We don't control these third-party cookies, but we only work with reputable educational technology providers.
For example, if we embed a coding sandbox to let you practice encryption algorithms, that sandbox provider might use cookies to save your code between sessions. Always check their privacy policies if you're concerned.
Data Retention and Your Rights
We don't keep cookie data forever. Analytics information gets aggregated and anonymized after six months. Session cookies disappear when you close your browser. Preference cookies last until you clear them or they expire.
You can request deletion of any data associated with your account at any time. Send us an email at support@waveflash.dev and we'll process your request within two weeks. You can also export your data to see exactly what we've stored.
Taiwan Privacy Note: As a service operating in Taiwan, we comply with local data protection requirements. Your information stays secure and we only process it for legitimate educational purposes.
Updates to This Policy
Technology changes and so do our practices. When we update this policy, we'll change the date at the top and notify active users through email. Major changes will get a prominent notice on the site itself.
We recommend checking back occasionally, especially if you're concerned about privacy. We're transparent about how we use tracking technologies because we believe you deserve to know what happens with your data.
Questions About Cookies?
If something in this policy isn't clear, or you want more details about how we use tracking technologies, reach out to us. We're happy to explain.
