Privacy Policy
Last Updated: January 15, 2025
At signal-stream, we handle your personal information with the care it deserves. This privacy policy explains exactly what data we collect, why we need it, and what we do with it. We're based in Taiwan and follow local regulations, but we believe in being transparent no matter where you're accessing our service from.
We're not fans of legal jargon that hides the truth. So we've written this in plain terms. If something isn't clear, reach out and we'll explain it better.
Information We Collect
When you use our valuation techniques platform, we gather different types of information. Some you give us directly, other bits come from how you interact with our courses and tools.
Data You Provide Directly
- Account details when you register (name, email address, phone number if you choose to share it)
- Professional background information to tailor your learning experience
- Payment information when you enroll in programs (processed through secure third-party providers)
- Questions and feedback you send us through contact forms or support channels
- Content you create within the platform, like notes or project work
Data We Collect Automatically
Like most online platforms, we track certain technical information about how you use signal-stream. This helps us improve the experience and spot any issues quickly.
- Device information (browser type, operating system, screen resolution)
- IP address and general location data
- Pages you visit and features you use most often
- Time spent on different sections of the platform
- Links you click and documents you download
How We Use Your Information
We're not in the business of selling data or bombarding you with marketing. Your information serves specific purposes that make the platform work better for you.
| Purpose | Data Used | Legal Basis |
|---|---|---|
| Delivering educational content | Account details, learning progress | Contract performance |
| Processing payments | Payment information, contact details | Contract performance |
| Improving platform features | Usage data, technical information | Legitimate interest |
| Sending course updates | Email address, course enrollment | Contract performance |
| Providing customer support | Contact information, issue details | Contract performance |
| Security and fraud prevention | IP address, device data, usage patterns | Legitimate interest |
Note on Marketing: We'll only send you promotional emails if you've explicitly agreed to receive them. And you can unsubscribe anytime with one click. We mean that – no dark patterns or hidden processes.
Data Sharing and Third Parties
We work with a handful of trusted service providers who help us run the platform. They only get access to data they absolutely need, and they're contractually required to protect it.
Service Providers We Work With
- Payment processors for handling transactions securely
- Cloud hosting providers for storing platform data
- Email service providers for sending course communications
- Analytics tools to understand platform usage patterns
- Customer support software to help us respond to your questions
We don't sell or rent your data to anyone. Period. If there's ever a legal requirement to share information (like a valid court order), we'll notify you unless we're legally prohibited from doing so.
International Data Transfers
Some of our service providers are based outside Taiwan. When your data crosses borders, we make sure it's protected through standard contractual clauses and other safeguards recognized by Taiwan's Personal Data Protection Act.
Your Privacy Rights
Under Taiwan's Personal Data Protection Act, you have substantial control over your personal information. Here's what you can do:
Access Your Data
Request a copy of all personal information we hold about you. We'll provide it in a readable format within 30 days.
Correct Inaccuracies
Update or fix any incorrect information in your account. Most of this you can do yourself through account settings.
Delete Your Account
Request complete deletion of your account and associated data. We'll process this within 30 days unless we have a legal reason to retain certain information.
Withdraw Consent
If you've opted into marketing or optional data collection, you can withdraw that consent anytime.
Object to Processing

Data Portability
Request your data in a structured format that you can transfer to another service.
How to Exercise Your Rights
Send us an email at support@signal-stream.com with your request. We'll verify your identity (to protect your data from unauthorized access) and respond within 30 days. There's no fee for most requests, though we might charge a reasonable administrative cost for excessive or repetitive requests.
Data Security Measures
We take security seriously because your trust matters. Here's what we do to protect your information:
- All data transmission uses industry-standard SSL/TLS encryption
- Stored data is encrypted at rest using AES-256 encryption
- Access to personal data is restricted to employees who need it for their work
- We conduct regular security audits and vulnerability assessments
- Staff receive ongoing training about data protection and security practices
- We maintain incident response procedures for potential data breaches
- Multi-factor authentication protects administrative access to systems
That said, no system is completely bulletproof. If we ever experience a data breach that affects your information, we'll notify you promptly and explain what happened, what data was involved, and what steps we're taking.
Data Retention
We don't keep your data forever. Different types of information have different retention periods based on legal requirements and practical needs.
Retention Periods
- Account data: Retained while your account is active, plus 90 days after account closure
- Course progress and materials: Kept for 2 years after last activity to support continued learning
- Payment records: Maintained for 7 years as required by Taiwan tax regulations
- Marketing preferences: Kept until you unsubscribe or withdraw consent
- Support communications: Retained for 3 years to help resolve recurring issues
- Usage logs: Automatically deleted after 18 months
When we delete data, we actually delete it – not just hide it. Backups are securely overwritten according to our data destruction procedures.
Cookies and Tracking
We use cookies – small text files stored on your device – to make the platform work properly and remember your preferences. Some are essential (you can't use the platform without them), while others are optional.
Types of Cookies We Use
- Essential cookies: Keep you logged in and remember your course progress
- Preference cookies: Remember your settings like language or display options
- Analytics cookies: Help us understand which features are useful and which need improvement
- Security cookies: Detect suspicious activity and prevent unauthorized access
You can control cookie preferences through your browser settings, though disabling essential cookies will prevent you from using core platform features. We don't use any third-party advertising cookies on signal-stream.
Children's Privacy
Our platform is designed for professional financial analysts and adult learners. We don't knowingly collect information from anyone under 18 years old. If you're a parent and believe your child has provided us with personal data, contact us immediately and we'll delete it.
Changes to This Policy
We update this privacy policy occasionally to reflect new features, legal requirements, or changes in how we handle data. When we make significant changes, we'll notify you by email and display a prominent notice on the platform.
The "Last Updated" date at the top shows when the current version took effect. We keep previous versions archived, so you can see what changed if you're curious.
Questions or Concerns?
If something in this policy isn't clear, or if you have concerns about how we handle your data, we want to hear from you. Seriously – we read and respond to every privacy inquiry.
You also have the right to lodge a complaint with Taiwan's National Development Council if you believe we've mishandled your personal information. But please talk to us first – we'd like the chance to resolve any issues directly.
