Privacy Policy
This page explains how Screen Size Detector handles your data. We built this tool with privacy as a core principle — all detection happens inside your browser, and no personal information ever leaves your device.
Local Detection Only
When you visit our homepage, your browser reads display information from the built-in window.screen API. This data never leaves your computer. We do not send it to any server, third-party service, or analytics platform.
No Data Collection
We do not collect, store, or process any personal data. You can use this tool without creating an account, entering your email, or providing any identifying information. Your screen resolution, viewport size, and other detected metrics remain entirely private.
Cookies & Storage
We use your browser's localStorage to remember your preferred unit (inches or centimeters) and decimal precision setting. This data stays on your device and is never transmitted to us. We do not use tracking cookies or advertising identifiers.
Third-Party Services
This website is hosted on a cloud platform that may log basic request data (such as your IP address and user agent) for security and performance purposes. This is standard hosting infrastructure logging and is not controlled by Screen Size Detector directly. We do not integrate with analytics, advertising, or social media trackers.
Your Rights
Because we do not collect or store personal data, there is no personal data to access, correct, or delete. You can clear any locally stored preferences at any time by removing site data from your browser settings.
If you have any questions about this privacy policy or how we handle data, feel free to contact us.
