Privacy Policy
Last updated: March 2025
At NetworkSignalLink, we take your privacy seriously. This policy explains how we handle information when you use our English grammar learning services in Hong Kong.
We've written this in plain language because privacy shouldn't require a law degree to understand. If anything seems unclear, just reach out and ask.
What Information We Collect
Information You Give Us Directly
When you sign up for our language courses or contact us, we collect basic details that help us provide better service:
- Your name and preferred contact details
- Email address for course updates and communication
- Phone number if you want appointment reminders
- Current English proficiency level (helps us place you correctly)
- Learning goals and areas where you want to improve
- Payment information for course enrollment
Information We Collect Automatically
Our learning platform collects some technical data to work properly and improve your experience:
- Device type and browser information
- IP address and general location (city level, not your exact address)
- How you navigate through our course materials
- Which grammar exercises you complete and your progress
- Time spent on different sections
- Error logs if something breaks (helps us fix issues faster)
Student Progress Data: We track your quiz scores, completed lessons, and areas where you're struggling. This helps our instructors provide personalized support.
How We Use Your Information
We're not in the business of selling data. Everything we collect serves a practical purpose:
- Delivering the grammar courses you enrolled in
- Sending progress reports and course updates
- Personalizing lesson recommendations based on your weak spots
- Processing payments and maintaining enrollment records
- Responding to your questions and support requests
- Improving our teaching methods and course content
- Meeting legal requirements under Hong Kong regulations
We occasionally send emails about new courses or grammar resources. You can opt out anytime—there's an unsubscribe link in every message.
| Data Type | Purpose | Retention Period |
|---|---|---|
| Contact Information | Course delivery and communication | Active enrollment plus 2 years |
| Progress Records | Track learning and provide feedback | Active enrollment plus 3 years |
| Payment Data | Transaction processing and records | 7 years (tax requirements) |
| Technical Logs | System maintenance and security | 90 days |
Who We Share Information With
We keep your information close to the chest. The only time we share it is when absolutely necessary:
Service Providers
We work with carefully selected companies that help run our platform:
- Payment processors for secure transactions (they never see your full card details)
- Email service for sending course materials and updates
- Cloud hosting provider for storing course content safely
- Customer support platform for managing your questions
These partners can only use your data to provide services to us—they can't use it for their own purposes.
Legal Requirements
If Hong Kong authorities request information under proper legal process, we may need to comply. We'll notify you unless prohibited by law.
What We Don't Do: We don't sell your information to advertisers, rent contact lists, or share your learning progress with third parties for marketing purposes.
How We Protect Your Information
Security isn't just technical—it's how we think about everything we build:
- All data transfers use industry-standard encryption
- Payment information goes directly to our processor (we never store full card numbers)
- Staff access is limited to only what's needed for their role
- Regular security audits and updates to our systems
- Secure backups stored in Hong Kong data centers
- Two-factor authentication available for your account
No system is completely bulletproof, but we take every reasonable precaution. If something goes wrong, we'll let you know promptly.
Your Rights and Choices
Under Hong Kong's Personal Data Privacy Ordinance, you have several rights regarding your information:
Access and Correction
You can request a copy of what information we hold about you. If something's wrong, let us know and we'll fix it. Most student information is accessible through your account dashboard.
Data Portability
Want to take your progress records elsewhere? We can provide your learning data in a standard format within 30 days of your request.
Deletion
You can ask us to delete your account and associated data. Keep in mind we may need to retain some records for legal or legitimate business purposes (like payment history for tax compliance).
Marketing Communications
Unsubscribe from our emails anytime using the link at the bottom. This won't affect essential course-related messages like enrollment confirmations or schedule changes.
To Exercise Your Rights: Email us at contact@networksignallink.com with your request. We'll respond within 14 days and complete most requests within 30 days.
Cookies and Tracking
Our website uses cookies—small files stored on your device that help things work smoothly. Here's what we use them for:
- Essential cookies: Keep you logged in and remember your course progress
- Performance cookies: Help us see which lessons work well and which need improvement
- Preference cookies: Remember your settings and language preferences
You can disable cookies in your browser, but some features might not work properly. Our learning platform needs essential cookies to function.
We don't use advertising cookies or share data with advertising networks.
International Data Transfers
Your data stays primarily in Hong Kong. Some of our service providers operate servers in other regions, but we ensure they meet Hong Kong's privacy standards through:
- Contractual protections requiring equivalent security measures
- Encryption during transfer and storage
- Regular compliance reviews
If you're accessing our courses from outside Hong Kong, your data may pass through international networks. By using our services, you understand this arrangement.
Children's Privacy
Our courses welcome students of all ages. For learners under 18, we require parental consent before collecting any personal information.
Parents can review their child's information, request corrections, or ask for deletion at any time. We collect only what's necessary for providing educational services—nothing more.
Changes to This Policy
We update this policy occasionally as our services evolve or regulations change. When we make significant changes, we'll notify you via email or a prominent notice on our website.
The "Last updated" date at the top shows when we last revised this document. We recommend checking back periodically, especially before sharing new information with us.
Continuing to use our services after changes take effect means you accept the updated policy.
Data Retention
We don't keep information longer than necessary. Once you complete your courses or close your account, we retain data according to these guidelines:
- Learning progress and course materials: 3 years after last activity
- Payment records: 7 years (required by Hong Kong tax law)
- Support correspondence: 2 years after resolution
- Marketing preferences: Until you unsubscribe or request deletion
After these periods, we securely delete or anonymize your information so it can't be traced back to you.
