Privacy Policy 隐私政策

Published on October 31, 2026 发布于 2026年10月31日

1. Overview & Commitment to Privacy

Welcome to aoliu.tech (the “Website”), the personal website, portfolio, and digital showcase of Ao Liu, Ph.D. (“I”, “me”, “my”, or “Website Owner”).

I respect your fundamental privacy rights. This Website is built from the ground up on principles of data minimization, transparency, and user autonomy. This Privacy Policy explains what information is processed when you visit aoliu.tech, how it is handled, and your rights regarding your personal information.

2. Core Privacy Principles

  • No Tracking or Advertising Cookies: This Website does not deploy advertising trackers, behavioral profiling scripts, marketing pixels, or third-party ad networks.
  • No Account Required: You do not need an account, login, or subscription to browse any content, read articles, or interact with portfolio builds.
  • No Selling or Monetization of Data: I do not sell, rent, license, or monetize any personal data under any circumstances.
  • 100% Client-Side Interactive Builds: Web applications, interactive demos, and games hosted on this site (such as Magic Tower 3D) run entirely within your local web browser sandbox without transmitting telemetry back to any private server.

3. Information Handled & How It Is Used

A. Network & Infrastructure Telemetry

This Website is served via secure global cloud hosting and distribution infrastructure (such as AWS Amplify Hosting, GitHub Pages, or edge CDN providers). When your browser requests pages from aoliu.tech, standard network-level request data (such as temporary IP addresses, browser user-agent headers, and request timestamps) may be automatically processed by the infrastructure hosting provider solely to ensure secure transmission, mitigate Distributed Denial of Service (DDoS) attacks, and enforce transport security (HTTPS/TLS). This information is processed in accordance with the hosting provider’s infrastructure security policies and is not utilized by me to identify individual visitors.

B. Direct Communications (Email)

If you choose to reach out to me via email at ao@aoliu.tech, I will receive your email address and any information or attachments you choose to provide in your message. This correspondence is used exclusively to read and respond to your direct inquiry. Your email address will never be shared with third parties or added to marketing newsletters.

C. Client-Side Local Storage (localStorage)

This Website does not use tracking cookies. It uses minimal, privacy-friendly HTML5 localStorage strictly for essential user experience preferences:

  • site_lang: Remembers your preferred reading language (en or zh) so you do not need to re-toggle it on every page load.
  • Interactive Project States (e.g. Magic Tower 3D save states): Saves your in-game floor progress, character attributes, and audio volume solely inside your own device’s sandboxed browser storage. This data never leaves your device.

4. Interactive Projects & Games (e.g., Magic Tower 3D)

For interactive projects, games, and WebGL applications hosted on this domain:

  • All game logic, calculations, asset rendering, and state management execute 100% locally on your client machine.
  • No analytics SDKs, user telemetry, or progress data are uploaded to external databases.
  • For users accessing our dedicated mobile application distribution (Google Play / Apple App Store), a specialized mobile privacy policy is accessible at Magic Tower 3D Mobile Privacy Policy.

5. Third-Party Links & External Platforms

This Website contains links to external platforms and social channels (including YouTube, TikTok, X (Twitter), Xiaohongshu / 小红书, LinkedIn, GitHub, and Medium).

When you click an external link to visit any third-party service, your interaction on that platform is governed solely by that respective service’s privacy policy and terms of service. I encourage you to review the privacy notices of external platforms you choose to visit.

6. Children’s Privacy (COPPA & GDPR Compliance)

This Website provides general-audience informational, scientific, and portfolio content. It does not knowingly collect or solicit personal information from children under the age of 13 (or under 16 in the European Economic Area), in compliance with the Children’s Online Privacy Protection Act (COPPA) and EU General Data Protection Regulation (GDPR).

7. Your Data Rights (GDPR & CCPA/CPRA)

Depending on your jurisdiction, you may have rights under applicable data protection laws (such as the EU GDPR or California Consumer Privacy Act / CPRA):

  • The right to know whether any personal data has been retained.
  • The right to request the deletion or correction of any correspondence you have sent to me.
  • The right to clear your browser’s local storage and cache at any time through your browser settings.

To exercise any of these rights regarding direct communications, please email ao@aoliu.tech.

8. Updates to This Policy

This Privacy Policy may be updated periodically to reflect changes in site features, infrastructure, or applicable regulatory standards. Any changes will be posted directly to this page with an updated date.
