Controller Data Stays In The Browser
GamepadTesterOnline.org is designed so controller data privacy is simple: core diagnostics run locally in the browser. Button presses, stick axes, trigger values, raw mapping data, vibration choices, polling samples, MIDI notes, and HID permission results do not need to be uploaded to a server for the gamepad tester to work. This privacy policy treats gamepad tester privacy as a product requirement, not an afterthought.
The site has no user account system, no login, and no file upload. It does not ask for names, addresses, payment details, or controller serial numbers. The privacy policy is written around the actual behavior of the controller diagnostics rather than generic collection claims, so controller data privacy remains tied to what the browser tools actually do.
If a user contacts the project manually, they may choose to include diagnostic details such as browser, operating system, controller model, connection type, or observed values. Those details are provided by the user outside the live tester. The site cannot see local controller values unless the user sends them through a separate communication channel.
