This Legal Disclaimer clarifies trademark ownership, commercial independence, and the diagnostic limits of gpadtester.io. Last updated: November 4, 2026.
Non-Affiliation and Trademark Ownership
GPadTester is an independent diagnostic software project. GPadTester is not affiliated, associated, authorized, endorsed by, or in any way officially connected with Sony Interactive Entertainment Inc., Microsoft Corporation, Nintendo Co., Ltd., Valve Corporation, 8BitDo, or any of their respective subsidiaries or affiliates.
All registered trademarks, product names, logos, and brands mentioned on this website (including PlayStation, DualSense, DualShock, Xbox, Xbox Wireless Controller, Nintendo Switch, Joy-Con, Steam Controller, and others) belong exclusively to their respective owners.
References to these commercial brands, systems, or consoles are made strictly for descriptive purposes to identify hardware compatibility within web browser environments.
Nature of Diagnostic Readings
All visual meters, axis charts, button lights, deadzone calculations, and latency estimations produced by GPadTester are diagnostic estimates rather than certified measurement standards.
Values shown on screen reflect the raw or mapped data delivered by your web browser through the W3C Gamepad API. These figures can be influenced by operating system polling rates, driver configurations, Bluetooth interference, browser frame cycles, and display monitor refresh speeds.
Numerical output should be used as a practical troubleshooting indicator rather than an authoritative scientific benchmark.
Absence of Repair and Calibration Services
GPadTester is an observational software tool, not a physical repair service, calibration facility, or replacement program.
Our software cannot physically eliminate mechanical stick drift, replace worn potentiometer tracks, repair failed microswitches, or modify internal controller firmware.
If diagnostic testing reveals persistent input errors, hardware owners should consult the official repair channels, warranty documentation, or authorized service centers provided by their equipment manufacturer.
Browser Variations and Technical Limitations
Web browsers vary significantly in how they implement the Gamepad API. Certain browsers may not support vibration actuators, trigger pressure thresholds, or high polling rates.
GPadTester makes no guarantee that any specific gamepad will be detected or represented accurately on every combination of browser and operating system.
Users must evaluate the tool independently within their specific software environment.
Frequently Asked Questions
Is GPadTester affiliated with Sony, Microsoft, or Nintendo?
No. GPadTester is an independent website with no affiliation, endorsement, or formal partnership with any console or hardware manufacturer.
Can GPadTester recalibrate my controller analog stick firmware?
No. GPadTester only reads and visualizes input signals delivered to the browser and cannot write data to your controller firmware.
Are the latency and circularity numbers official industry measurements?
No. All numbers are informational diagnostic estimates derived from browser polling cycles and operating system reports.
