Privacy Policy of Engineer Tsai (Updated 2025)
Welcome to the Engineer Tsai Privacy Policy. This notice explains what information we collect, why we use it, and how we protect it. It also lists the tools we rely on and the choices you can make. If anything remains unclear, contact us—we usually reply within 24–48 hours (UTC+8).
1. Information We Collect
When you visit our site (and our PWA/App that loads the same content), we may automatically collect basic technical data such as:
- Your IP address and general location (city/region level)
- Browser type, device type, and OS
- Pages viewed and time of visit
- Referring website/UTM parameters
If you submit a form (e.g., newsletter sign-up, comment, contact form), we also collect:
- Your name or nickname
- Email address
- Any information you voluntarily provide in the message field
We do not knowingly collect sensitive categories of data.
2. How We Use Your Information
We use data to:
- Improve content and UX (what’s working, what isn’t)
- Send educational resources or updates you request
- Respond to questions and comments
- Analyze traffic and measure content performance
- Meet legal or operational obligations when necessary
Where possible, data is aggregated or pseudonymized; reports do not identify individual visitors.
3. Cookies & Third-Party Tools
Our site may use cookies or similar technologies to analyze traffic, embed media, and keep things running smoothly. Typical providers include:
- Google Analytics 4（anonymous/aggregated reporting）
- Google AdSense（if/when ads are enabled）
- YouTube embeds（to show videos and playlists）
- Social plugins（e.g., share buttons, comment systems）
- CDN/performance services（to load content faster）
You can manage or disable cookies in your browser settings. Some features may behave differently if cookies are disabled. Where required by law, we display a consent banner for EU/EEA/UK visitors.
4. Our Mobile App (PWA/Capacitor Shell)
If you install or use our App:
- The App loads the same web content; it follows this privacy policy.
- Some features (e.g., bookmarks) may store data locally on your device only.
- OS-level permissions (e.g., notifications) are opt-in and can be turned off in system settings.
- We do not access device contacts, photos, or sensors unless you explicitly grant permission for a specific feature.
5. Legal Bases (where applicable)
For GDPR-style regions, we rely on one or more lawful bases:
- Legitimate interests（site analytics, security, basic operations）
- Consent（optional cookies, newsletter, notifications）
- Contract（if you sign up for an account or paid service in the future）
- Legal obligation（record-keeping when required）
6. Data Retention
- Analytics logs are typically kept in aggregated form.
- Contact emails and form submissions are kept only as long as needed to respond and maintain records, then archived or deleted.
- If you request deletion, we will remove or anonymize your personal data unless we must keep it to comply with law.
7. Security
We use reasonable technical and organizational measures (HTTPS/TLS, access controls, least-privilege accounts, and updates) to protect your information. No method is 100% secure, but we work to reduce risk.
8. International Transfers
Our service providers may operate globally. When data is processed outside your country, we rely on appropriate safeguards provided by those vendors.
9. Your Rights & Choices
Depending on your location, you may have the right to access, correct, export, object to, or delete your personal data.
To exercise these rights, contact us using the details below. For cookies/ads, you can also adjust:
- Browser cookie settings
- Google Ads settings & YouTube cookie preferences (when using embeds)
10. External Links
Our site includes links to external websites. Their practices are not controlled by us; please review each site’s privacy policy.
11. Children’s Privacy
Our content targets students and professionals, but not children under 13 (or the age required in your region). If you believe a child provided personal data to us, please contact us and we will delete it.
12. Changes to This Policy
We may update this page from time to time. If changes are significant, we’ll post a notice on the site. Please check this page periodically.
