1. INTRODUCTION

At loideveloper.io.vn, we use cookies and similar tracking technologies to enhance your experience, optimize system performance, and maintain the highest standards of privacy and cybersecurity.

If you disagree, you may disable cookies in your browser, though certain functions may become limited.

2. WHAT ARE COOKIES?

Cookies are small encrypted text files that a website places on your device (computer, phone, or tablet) to store and retrieve information about your visit.

They help:

• Identify your browser type and preferences.
• Enable smoother navigation across pages.
• Enhance website speed, customization, and security.
• Record anonymous analytical data for performance improvement.

Cookies are not programs or malware; they do not execute code, collect personal data, or give external parties control of your system.

3. TYPES OF COOKIES USED ON THIS SITE

To ensure maximum transparency, below are all categories of cookies used on loideveloper.io.vn:

Disabling these cookies may break core functionality or prevent access to certain pages.

3.2. Performance & Analytics Cookies

These cookies collect anonymous data on how users interact with the site, including:

Each third-party service maintains its own privacy and cookie policies, which are outside our control.

We recommend reviewing those policies before engaging with embedded or linked content.
