Trackpad — Privacy Policy

Trackpad is developed by HeadSoft Tech (“we”, “us”) as a utility for Android, published under the package name net.headsoft.trackpad. It turns a phone’s own touchscreen into a trackpad for an external monitor connected over USB-C in desktop mode.

Nothing. Trackpad collects no personal information, no usage analytics, no device identifiers and no crash reports. There is no account, no sign-in, and no advertising.

This is not a policy promise layered on top of a system that could collect data — the app has no means of collecting it. See “No network access” below.

Android provides no way for an app to send pointer input to a second screen except through the AccessibilityService API. Trackpad therefore asks you to enable an accessibility service, and explains this inside the app, with an explicit consent step, before anything is turned on.

The service is used in two ways, both only at the moment you act:

• Sending input. Taps, drags and scrolls you make on the phone are dispatched as gestures to the external display. This is the app’s core function.
• Reading the element under the pointer, when you click. The Android desktop taskbar sits in a system window that ignores simulated touches, so the only way to operate it is to find the button under the pointer and ask it to activate itself. The same mechanism types into the text field you are focused on when you use the app’s on-screen keyboard, because it types by editing that field rather than by pressing keys.

What is read is used in that instant, in memory, to carry out the click or keystroke you just made, and is then discarded. It is never written to storage and never transmitted.

The app subscribes to no accessibility events and does not read the screen in the background. It does not log what you type, capture passwords, or monitor other apps.

Trackpad does not request the Android INTERNET permission. Without it, the operating system will not allow the app to open a network connection at all. No data can leave your device, to us or to anyone else, even in principle — this is enforced by Android, not by our good intentions, and you can verify it in the app’s permission list.

Your pointer sensitivity, acceleration curve, scrolling direction and your acceptance of the accessibility disclosure are stored locally in Android’s private app storage. They never leave the device and are removed when you uninstall the app or clear its data in Android Settings.

None. Trackpad contains no analytics SDK, no advertising SDK, no crash reporter and no Google Play Services dependency. Nothing in the app talks to a third party, because nothing in the app talks to anything.

Trackpad is a general-purpose utility and is not directed at children. Since it collects no personal information from anyone, it collects none from children either.

We hold no data about you, so there is nothing for us to retain. On-device settings persist until you uninstall the app or clear its data.

Because we hold no data about you, there is nothing to request access to, correct or delete on our side. Everything the app stores lives only on your device: uninstalling the app, or clearing its data in Android Settings, removes all of it. You can withdraw the accessibility permission at any time in Android Settings › Accessibility, which stops the app from functioning but requires no action from us.

If this policy changes, the update will be posted on this page with a new “last updated” date.
