Terms of Service

What EdgeSlide is

A system-tray app for Windows. It reads your Precision Touchpad, adjusts brightness and volume, and gets out of your way. No account, no backend, no cloud. Everything runs on your machine.

The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.

In plain language: use it, modify it, share it, build on it. Free, forever. Just keep the copyright notice in copies.

Pay-what-you-want

The app is free. Full stop. If you want to support development, there's an optional donation. A few things to know:

It's voluntary. Paying nothing gets you exactly the same software as paying something.
It grants no extra features, priority support, or entitlements of any kind.
Payments are non-refundable. They're a thank-you, not a purchase. There's nothing to return.
Donations are processed by Lemon Squeezy, whose own terms and privacy policy govern the transaction. We don't handle payment details directly.

No warranty

EdgeSlide is provided as-is, consistent with the MIT License above. We built it to work and intend to keep it working. But we make no guarantee that it will always be available, always be bug-free, or always behave exactly as expected on every combination of hardware, drivers, and Windows version in existence.

Specifically: the app reads touchpad input, modifies system brightness, and modifies system volume. Behavior depends on your hardware and drivers. Compatibility is limited to Windows Precision Touchpads on Windows 10 and 11. If it doesn't work on your setup, the GitHub issue tracker is the right place.

Limitation of liability

To the maximum extent permitted by applicable law, Amazing SAS and the author (stillfalling) are not liable for any indirect, incidental, special, or consequential damages arising from your use of EdgeSlide.

Note for EU/French users: Under French and EU consumer law, liability for gross negligence, willful misconduct, and certain statutory consumer rights cannot be excluded. The limitation above applies only to the maximum extent the law allows. Nothing here removes your statutory rights.

Hardware compatibility

EdgeSlide requires a Windows Precision Touchpad. It will not work on older HID-compliant touchpads or external mice. To check: Settings → Bluetooth & devices → Touchpad—if you see gesture controls, you're good.

The app modifies display brightness via Windows WMI and audio volume via the Windows Core Audio API. Results depend on your display hardware and audio drivers.
