stickdriftcheck.com ("we", "the site") provides a free browser-based controller stick drift test. This page explains what data is and isn't collected when you use the site.

How the test works

The drift test runs entirely in your browser using JavaScript and the Gamepad API. Your controller's input — stick positions, button presses, trigger values — is read and analyzed locally on your device. While you test, the site sends none of that input to any server. The one exception is a drift result you choose to save, which the next section describes.

Drift history

On the stick drift test and the controller test pages, you can save a finished drift check to a history for one controller. The page sends nothing until you press Save this check. When you press it, the page sends these items to sch3ma.com, which stores them for this site:

• The name you give the controller.
• The model name your browser reports for the controller, for example "DualSense Wireless Controller (STANDARD GAMEPAD Vendor: 054c Product: 0ce6)".
• The resting X and Y position and the offset of each stick from that check.
• The deadzone and the drift threshold (0.08) that the check used.

sch3ma adds the date and time that it receives each check. Your device's clock does not set that date.

The first save gives this browser an anonymous identity at sch3ma. sch3ma keeps the key to that identity in this browser's local storage and in a cookie on auth.sch3ma.com. Only that identity can read, change or delete your controllers and checks. Other visitors cannot see them. The site owner can read them through sch3ma's admin access.

If you ask for a sign-in link, for example with Keep this history on every device, you give an email address. sch3ma stores the address with your identity and sends the link to it. When you open that link on another device, the same history opens there.

To delete what you saved:

• Press Delete on a check to remove that check.
• Press Delete this controller to remove the controller and every check saved for it.
• Press Delete all my data to remove every controller and check, your identity, and your email address.

sch3ma keeps a deleted controller or check for 30 days, so the site owner can restore it after a mistake. After 30 days, sch3ma destroys it. When you delete all your data, sch3ma destroys your email address at once.

Cookies and advertising

Analytics

stickdriftcheck.com runs no analytics. No page loads an analytics script, and no page sends an analytics beacon. Nobody counts your visit, your country, or your device type. The only server this site contacts is sch3ma, and only when you save a drift check, which the drift history section above describes.
