Who We Are

CleverDataFlow operates as an educational platform based in Taiwan, providing blockchain technology courses and learning resources. Our physical location is at 104, Taiwan, Taipei City, Zhongshan District, Alley 9, Lane 630, Beian Road, 23號1樓. We're registered and operate in accordance with Taiwan's Personal Data Protection Act (PDPA).

When we say "we," "us," or "our" in this document, we're referring to CleverDataFlow and our team. "You" means anyone who visits our website, signs up for courses, or interacts with our services.

Information We Collect

What You Give Us Directly

When you register for our courses or contact us, you share certain information voluntarily. This usually includes:

• Your name and email address
• Phone number if you choose to provide it
• Educational background and experience level (helps us recommend appropriate courses)
• Payment information when you enroll in paid programs
• Messages you send through our contact forms or support channels

Technical Information We Gather Automatically

Like most websites, ours collects some data automatically through standard web technologies. This happens whether you create an account or just browse around:

• IP address and general location information
• Browser type and device information
• Pages you visit and time spent on our site
• Referring websites and search terms that brought you here
• Course progress and completion data for enrolled students

How We Use Your Information

We're not in the business of selling data. Everything we collect serves specific purposes related to running our educational platform:

We occasionally send educational content and course recommendations, but only if you've indicated interest. You can unsubscribe from these emails anytime through the link at the bottom of each message.

Who Sees Your Data

We keep your information within our team as much as possible. However, running an online platform means working with some trusted partners:

Service Providers We Work With

• Payment processors: Handle credit card transactions securely (we never see your full card number)
• Email service: Helps us send course updates and communications
• Hosting provider: Stores our website and learning materials
• Analytics tools: Give us insights into website traffic and user behavior

These companies can only use your data for the specific services they provide to us. They're contractually required to protect your information and can't use it for their own purposes.

Legal Requirements

Sometimes we're legally obligated to share information with authorities. This only happens when required by Taiwan law or in response to valid legal processes like court orders. We'll notify you if this occurs unless prohibited by law.

Your Rights Under Taiwan Law

Taiwan's Personal Data Protection Act gives you specific rights regarding your information. Here's what you can do and how to do it:

Access Your Data

You can request a copy of all personal information we hold about you. We'll provide this in a readable format within 30 days. There's no charge for your first request in a calendar year.

Correct Inaccurate Information

Found something wrong in your profile? You can update most information directly through your account settings. For data you can't change yourself, contact us and we'll fix it within 15 business days.

Delete Your Account

Want to leave? You can request account deletion at any time. We'll remove your personal data within 45 days, though we may keep some information longer if required by law (like financial records for tax purposes).

Restrict Processing

You can ask us to stop using your data for certain purposes, like marketing communications, while still keeping your account active for course access.

Data Portability

If you want to move your data to another service, we'll provide your information in a common, machine-readable format.

How We Protect Your Information

Security isn't just a checkbox for us — it's built into how we operate. Our approach includes multiple layers:

Technical Safeguards

• All data transmission uses industry-standard SSL/TLS encryption
• Passwords are hashed using bcrypt before storage (we can't see your actual password)
• Regular security audits and vulnerability scanning
• Firewalls and intrusion detection systems on our servers
• Automated backups with encrypted storage

Administrative Measures

Our team members only access data when necessary for their specific roles. We use multi-factor authentication for all admin accounts and conduct regular training on data protection practices.

Despite our precautions, no system is completely impenetrable. If a data breach affects your information, we'll notify you within 72 hours as required by Taiwan's PDPA, along with details about what happened and steps we're taking to address it.

How Long We Keep Your Data

We don't keep information longer than necessary. Here's our general approach to retention:

• Active students: Your data stays active as long as you have an account and for one year after your last course completion
• Inactive accounts: If you haven't logged in for three years, we'll send a reminder email. No response means we'll delete your account after another 90 days
• Financial records: Kept for seven years to comply with Taiwan tax law
• Marketing communications: Contact information from inquiries is kept for two years unless you unsubscribe
• Technical logs: Server logs and analytics data are anonymized after six months

After these periods, we either delete data permanently or anonymize it so it can't be traced back to you. Anonymized data might be used for research or improving our courses, but it contains no personally identifiable information.

International Data Transfers

Our primary servers are located in Taiwan, but some service providers we use may store data on servers in other countries. When this happens, we ensure those providers meet data protection standards equivalent to Taiwan's requirements.

If you're accessing our platform from outside Taiwan, your information will be transferred to and processed in Taiwan. By using our services, you acknowledge this transfer. We take steps to ensure your data receives the same level of protection regardless of where it's processed.

Children's Privacy

Our courses are designed for adults and professionals. We don't knowingly collect information from anyone under 16 years old. If you're under 16, please don't register for our platform or provide any personal information.

Parents who discover their child has provided information to us should contact us immediately. We'll delete that information from our systems within 15 business days of verification.

Changes to This Policy

We update this policy occasionally to reflect changes in our practices or legal requirements. The "Last Updated" date at the top shows when we last made changes.

For minor updates (like clarifying existing practices), we'll post the revised policy on this page. Significant changes that affect how we handle your data will trigger an email notification to all registered users at least 30 days before the changes take effect.

Continuing to use our platform after changes go live means you accept the updated policy. If you disagree with the changes, you can close your account before they take effect.

Third-Party Links

Our courses sometimes reference external resources and websites. We're not responsible for the privacy practices of these third-party sites. When you click a link that takes you away from cleverdataflow.com, this privacy policy no longer applies.

We encourage you to read the privacy policies of any website that collects your personal information. We try to link only to reputable sources, but can't control or endorse their data handling practices.
