Introduction

Yalintech ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our website (yalintech.com), web-based tools, and mobile applications.

Please read this privacy policy carefully. By using our website or apps, you agree to the collection and use of information in accordance with this policy.

Information We Collect

Website & Web Tools

• Browser Information: Our Device Specs tool reads browser, OS, screen, and hardware info using standard browser APIs. This data is displayed to you locally and is never transmitted to our servers.
• Microphone Access: Our Sound Meter tool requests microphone access to measure ambient noise levels. Audio is processed in real-time in your browser and is never recorded, stored, or transmitted.
• QR Code Data: Our QR Code Generator processes your input (URLs, text, Wi-Fi credentials) to create QR codes. This data is sent to a third-party QR rendering service (api.qrserver.com) to generate the image. No data is stored by us.
• Unit Conversions: All conversions are calculated locally in your browser. No data is sent to any server.
• Website Analytics: We use Google Tag Manager and anonymized analytics to understand how visitors interact with our website.
• Contact Information: If you contact us through our website, we collect the information you provide (name, email, message).

Mobile Apps

• Usage Analytics: We use anonymized analytics to understand how users interact with our apps, helping us improve the user experience.
• Crash Reports: If an app crashes, we may collect crash logs to help identify and fix bugs.
