Privacy Policy

Last Updated: October 2026 • Effective Date: Immediately upon access

At OnlineScreenTester.com, protecting your digital privacy is our foundational engineering principle. This Privacy Policy details our transparent policies regarding the collection, use, and disclosure of data when you utilize our browser-based display testing, monitor calibration, and pixel inspection suite.

1. The Client-Side Execution Guarantee

Unlike legacy hardware utility tools that require executable installations or cloud transmission of device profiles, OnlineScreenTester operates 100% client-side inside your browser runtime.

When you execute our full-screen color stages, 60Hz stuck pixel revival cycles, UFO motion tests, or touchscreen digitizer sweeps:

  • All graphics rendering is processed locally in volatile browser memory (RAM) via HTML5 Canvas, WebGL, and CSS.
  • No display snapshots, camera photos, or video streams are transmitted to our servers or third-party networks.
  • Our Webcam Studio Light tool utilizes your screen as an illumination softbox and does not access, record, or stream your webcam hardware.
  • Touch coordinate data generated in our Touch Screen Test is discarded immediately upon clearing the test canvas or navigating away.

2. Information We Collect and Process

We deliberately minimize data interaction to the absolute technical minimum required to host and secure a high-performance web service:

A. Technical Server Logs (Non-Identifiable)

When you load OnlineScreenTester.com, our content delivery network (CDN) and hosting infrastructure automatically record standard web server log entries. This data includes your device's Internet Protocol (IP) address, browser user-agent string, operating system type, referring URL, and page timestamps. These logs are used solely for DDoS prevention, bot detection, server load balancing, and overall network reliability.

B. Local Browser Storage (Client-Side Only)

We may utilize browser localStorage solely to remember your preferred UI theme (Dark Mode vs. Light Mode) and temporary benchmark records while generating an Inspection Certificate. This data remains on your physical device and is never uploaded to remote databases.

3. Cookies, Web Beacons & Third-Party Advertising

To maintain OnlineScreenTester.com as a free utility available to users worldwide without subscription paywalls, we partner with third-party advertising networks, including Google AdSense.

How Google Uses Cookies:

  • Google, as a third-party vendor, uses cookies (such as the DoubleClick DART cookie) to serve ads based on prior visits to our website and other sites across the Internet.
  • Users may opt out of personalized advertising by visiting Google Ads Settings.
  • Alternatively, you can opt out of third-party vendor cookies for personalized advertising by visiting aboutads.info.

4. Privacy Rights (GDPR & CCPA / CPRA)

Whether you reside in the European Economic Area (EEA), the United Kingdom, California, or elsewhere globally, we respect your statutory privacy rights:

European GDPR Rights

You retain the right to request access to any personal data processed, object to processing, request data portability, and request rectification or erasure of any logged data. Because we do not mandate user registration, we hold no user profiles or linked identifiable data.

California Consumer Rights (CCPA)

California consumers possess the right to know what personal categories of data are collected, request deletion, and opt out of the sale or sharing of personal information. We do not sell personal information to data brokers under any circumstances.

5. External Links & Diagnostic Resources

Our knowledgebase articles and FAQ guides may contain links to external reference documentation (such as ISO standard whitepapers, VESA specifications, or official manufacturer support portals). OnlineScreenTester.com holds no control over the content, privacy policies, or practices of third-party websites and assumes no liability for their operations.

6. Children's Privacy (COPPA Compliance)

OnlineScreenTester.com is designed as a universal technical utility for users of all ages. We do not knowingly solicit, collect, or maintain personally identifiable information from children under the age of 13 in compliance with the Children's Online Privacy Protection Act (COPPA).

7. Modifications to This Policy

We may update our Privacy Policy periodically to reflect technological improvements, legal changes, or enhancements to our diagnostic suite. Any revisions will be posted directly to this URL with an updated "Last Updated" timestamp. We encourage users to review this page periodically.
