Privacy Policy

1. Introduction

Welcome to SizeScreen.com ("we," "our," or "us"). We operate the website at https://sizescreen.com, which provides free screen size detection, PPI calculation, responsive testing, device comparison, and related educational tools for developers, designers, and everyday users.

This Privacy Policy explains what information we collect, how we use it, and what rights you have with respect to your data when you use our website and services. We are committed to protecting your privacy and being transparent about our practices.

2. Information We Do NOT Collect

Our core tools — screen size detection, viewport measurement, PPI calculation, and device comparison — operate entirely within your browser using client-side JavaScript. No data from these tools is ever transmitted to our servers. Specifically, we do NOT collect:

• Your screen resolution, viewport dimensions, or pixel ratio
• Your device type, operating system, or hardware specifications detected by our tools
• Your IP address through our screen detection tools (the IP Checker simply displays your IP — it is not stored)
• Your name, email address, or any personally identifiable information (unless voluntarily provided via our contact form)
• Payment information of any kind
• Biometric data, location data, or sensitive personal information

We do not sell, rent, trade, or share any user data with third parties for marketing purposes. Period.

• Cookies: Small text files placed in your browser by third-party services such as Google AdSense and Google Analytics
• Usage data: Aggregated, anonymized statistics about how users interact with our website (page views, session duration, etc.)

This data is used solely for maintaining site security, diagnosing technical issues, and understanding aggregated traffic patterns. It is not used to personally identify you.
