Privacy Policy
Last Updated: September 2, 2026 · Effective Date: September 2, 2026
Privacy at a Glance
Touch coordinates, contact radius, and pressure data are computed strictly inside your browser sandbox. Nothing is transmitted or saved.
We use Google Analytics (GA4) with IP anonymization to evaluate aggregate traffic and diagnose platform performance.
Third-party advertising partners like Google AdSense use standard cookies. You can customize or opt out of ad personalization anytime.
1. Introduction
At Touch Screen Test ("we," "our," or "the platform"), we believe that hardware diagnostics should be accurate, instantaneous, and completely respectful of your personal privacy. This Privacy Policy details the types of information we process when you visit our website, how that information is utilized, and the rights and controls you have regarding your personal data.
By accessing or interacting with our platform, you acknowledge that you have read, understood, and agreed to the data practices outlined in this policy. If you do not agree with these practices, please discontinue use of the site.
2. Zero Touch Telemetry Architecture
Our testing suite—including Single-Touch Calibration, Multi-Touch Detection, Deadzone Matrix Testing, and Pixel Uniformity Color Washes—runs entirely client-side using standard W3C Pointer Events, HTML5 Canvas, and modern Web APIs.
Under no circumstances do we collect, record, or transmit:
- Your screen touch coordinates (X, Y pixels)
- Individual finger trajectories, stroke speeds, or gesture patterns
- Touch pressure, contact area geometry, or stylus tilt angles
- Deadzone completion percentages or digitizer test results
All canvas rendering data resides solely in your device's volatile memory and is instantly purged when you clear the canvas, change modes, or close your browser tab.
3. Automatically Collected Technical Information
Like virtually all modern web services, our web hosting servers and infrastructure providers automatically process standard, non-personally identifiable technical logs when you request web pages:
- Network & Log Information: Anonymized Internet Protocol (IP) address, approximate geographic region (country/city level), timestamps of requests, referring and exit page URLs, and HTTP response codes.
- Device & Environment Data: Browser software (e.g. Safari, Chrome, Firefox, Edge), operating system (e.g. iOS, Android, macOS, Windows), viewport screen dimensions, and system language preferences.
- Service Reliability Data: Network transfer latencies, asset loading speeds, and client-side error telemetry required to maintain website availability.
4. Google Analytics (GA4) Disclosures
We use Google Analytics, an industry-standard web analytics tool provided by Google LLC ("Google"), to help us analyze how visitors navigate and utilize our site. Google Analytics uses first-party cookies and pseudo-anonymous identifiers to generate aggregated, statistical reports regarding visitor volume, session duration, bounce rates, and popular diagnostic features.
We have configured Google Analytics to anonymize IP addresses and minimize data retention. Google does not link your IP address with other data held by Google unless you have explicitly authorized Google to do so through your personal Google account settings.
Opt-Out Mechanism: If you wish to prevent your browsing sessions from being measured by Google Analytics, you can download and install the official Google Analytics Opt-out Browser Add-on.
5. Google AdSense & Third-Party Advertising
To maintain our testing utilities as a completely free public service without subscription fees or paywalls, we partner with Google AdSense and trusted advertising networks to display relevant digital advertisements.
Please review the following essential disclosures regarding advertising technologies on our platform:
- Third-Party Vendor Cookies: Third-party vendors, including Google, use cookies (including the DoubleClick and DART cookies) to serve ads based on a user's prior visits to this website or other websites across the Internet.
- Personalized Advertising: Google's use of advertising cookies enables it and its advertising partners to serve personalized advertisements to you based on your visits to our site and other destinations across the web.
- Managing Your Ad Preferences: You can manage or opt out of personalized advertising at any time through Google Ads Settings.
- Industry-Wide Opt-Out Tools: You can also opt out of third-party interest-based advertising cookies from participating advertising networks by visiting the Digital Advertising Alliance (DAA) or the Network Advertising Initiative (NAI).
6. Cookies and Browser Local Storage
Cookies and local storage keys are small data tokens stored securely on your device:
- Functional Storage: We use browser HTML5 LocalStorage solely to remember your chosen visual theme (Dark Mode vs. Light Mode). This preference contains no identifiable personal data and never leaves your browser.
- Analytics Cookies: Placed by Google Analytics to distinguish unique visits and track aggregate platform health.
- Advertising Cookies: Placed by Google AdSense and third-party ad exchanges to measure ad delivery, limit ad repetition, and serve relevant promotions.
You can configure your browser to reject all cookies or notify you whenever a cookie is requested. Please note that all core diagnostic touchscreen features operate fully and without restriction even if all cookies and storage mechanisms are blocked.
