1. What We Collect

On this Site we only collect what you actively provide:

Contact form: when you submit a message in the "Contact" section, the form opens your default email client (via mailto:), and you send the email yourself to our inbox. We do not store the message on any server.
Direct email: you can also email us directly at legal@lexu.com. We retain email correspondence only to the extent necessary.
What we do not collect: your name, email, phone number (unless you proactively provide them via the methods above), browser or device fingerprinting, browsing history, click stream, dwell time, or any form of user profiling.
The Site integrates no analytics, tracking, advertising, social-media pixel, or third-party crash-reporting service.

2. How We Use Information

We use any information you provide only to:

Respond to your inquiry
Improve the Site based on feedback you voluntarily provide
Maintain Site security and troubleshoot issues
Not for: advertising, behavioural analysis, automated decision-making, commercial purposes, or resale to third parties

3. Cookies and Local Storage

This Site does not use cookies and does not deploy any cross-site tracking. We only use the browser's localStorage (which lives only on your device and is not shared across devices or sites) to remember:

Theme preference: light or dark
Language preference: Chinese or English
You can clear this data at any time via your browser settings, or reset it using the theme / language toggle on the Site
Clearing it does not affect Site functionality

4. Third-Party Services and External Links

This Site is a pure static site (HTML / CSS / JavaScript files) distributed via CDN or static hosting. We do not operate a backend of our own. The only third-party services we rely on are:

Static hosting / CDN: distributes the Site's static assets. The hosting provider may log access IP and User-Agent (governed by their own privacy policy).
Apple App Store: links to the App Store download pages. Apple takes over once you tap the link (governed by the Apple Privacy Policy).
External links: the Site may link to third-party websites (App Store, GitHub, blog, etc.). Once you click those links and leave the Site, this Policy no longer applies.
Not integrated: web analytics (Google Analytics, Baidu Tongji, Plausible, etc.), behavioural tracking, ad networks, third-party crash reporting, social-media tracking pixels.

5. Your Rights

Because the Site collects almost no personal information, most rights are not exercisable in practice (no account, no data to access). However, you still have:

Right of access: you can write to us to request any information we hold about you (e.g. email correspondence)
Right of correction: if information you provided in an email is wrong, you can ask us to correct it
Right of deletion: you can ask us to delete our email correspondence or message history with you
Right to complain: if you believe we are violating applicable laws, you may complain to the relevant regulator

6. Children's Privacy

The Site is intended for adult users:

We do not knowingly collect personal information from children under 13
If you believe we have collected information from a child under 13 without verifiable parental consent, contact us at legal@lexu.com and we will assist in deletion
Where this Policy conflicts with applicable law, applicable law prevails

7. Changes to this Policy
