Privacy Policy

Effective date: October 8, 2026

The short version: DPI Analyzer Pro collects nothing about you. Everything on this site runs locally in your browser. There are no accounts, no tracking cookies, no analytics, and no advertising. This page explains exactly what that means in practice.

What we don't collect

• No accounts. You never sign up, log in, or provide a name, email, or any identifier to use the tools.
• No tracking cookies. This site sets zero cookies — not for tracking, not for advertising, not for analytics.
• No analytics. We don't run Google Analytics or any other analytics service. We have no idea how many people visit, which pages they read, or what they click.
• No advertising. There are no ad scripts, ad trackers, or sponsored content on this site.
• No server-side data. The site is static. Your mouse measurements, calculator inputs, and test results are computed in JavaScript in your browser and never sent to a server — there isn't one listening.
• No third-party requests. Pages load no external fonts, scripts, images, or embeds. Your browser talks only to dpianalyzerpro.com.

What stays on your device

The DPI analyzer can optionally keep your session history (past measurement trials) so you can review it during your visit. This is stored in your browser's localStorage under keys beginning with dpianalyzerpro_. It never leaves your device. Clearing your browser's site data deletes it permanently.

Contact emails

If you email contact@dpianalyzerpro.com, we receive whatever you choose to send — typically your name, email address, and message. We use it only to reply. We don't add you to any list, share it, or sell it. (There is no list.)

Future changes

If advertising (such as Google AdSense) or analytics are ever added to this site, this policy will be updated first to disclose exactly what is collected, by whom, and why — before a single tracking script loads. The effective date above will change, and the change will be noted here.
