Privacy: Your Controller Data Stays on Your Device
Short version: the tester reads your controller in your browser only. Button presses, stick values, device names and test results never leave your device. We set no cookies. We count anonymous usage, and that count cannot be linked to you.
Who we are
Controller Check (controllercheck.app) is a free online tool run by 1000 Ventures. Contact: michael@1000ventures.io.
Your controller data stays on your device
When you press a button, your browser lets this page read your controller through the Gamepad API. The page draws the buttons, sticks and triggers and works out the test results right there in your browser. There is no code on the page that sends button presses, stick values, the controller's name or any test numbers to us or to anyone else. Nothing is saved: reload the page and it starts fresh.
Anonymous usage statistics
When you use the tool, we count that use in an anonymous, aggregate statistic. Each count contains only the event, a coarse category (that a controller connected, or the drift verdict: no drift, mild drift or drift) and which of our two test pages you used, plus a country-level location, your device type and the hour it happened. It never contains stick values, button presses or device names. We store no IP address, set no cookies and attach no identifier of any kind, so no count can be linked to you. If your browser sends a Global Privacy Control or Do Not Track signal, we do not count anything at all.
We also note, in one word, where a visit came from: a search engine, an AI assistant, one of our other sites, a social network or no referrer at all. Your browser sends only the host name of the page that linked to us, and we keep just that one-word channel. The address of the page you came from is never stored.
Server logs
Like every website, our hosting provider (Render) receives standard request information when your browser loads a page, such as the IP address and the page requested, to deliver the page and protect against abuse. We do not use these logs to track or profile visitors.
Cookies
We set no cookies. The site works without any.
Advertising
This site shows no ads. If that changes, this section will name the ad partner, explain its cookies and the consent choices before any ad runs.
Your rights (GDPR)
We operate from the EU and aim to comply with the GDPR. Because the tool collects no personal data, there is normally nothing personal we hold about you. Write to us at the address above with any request.
Changes
We update this page when what we do changes. Last reviewed .
Check your controller in the browser: every button, both sticks, drift and vibration.
