Terms of Service

Last updated: July 14, 2026

The short version: KnurlPad is a $6.99 one-time macOS app sold through Gumroad. Buy it, use it on the Macs you own. It is provided as-is, and all sales are final.

Agreement

By purchasing, downloading, or using KnurlPad (the "app"), you agree to these terms. If you do not agree, do not use the app. The app is made by Kevin Tang.

License to use

Your purchase grants you a personal, non-exclusive license to install and use the app on Macs that you own or control. You may not resell or redistribute the compiled binary as your own.

Purchases and payments

The app is sold through Gumroad. Your payment and contact details are handled by Gumroad under their terms and privacy policy; the app itself never sees or receives them.

Refunds

All sales are final and refunds are not offered. If you run into a bug, email me and I will do my best to make it right.

Disclaimer of warranty

The app is provided "as is" and "as available," without warranty of any kind, whether express or implied, including fitness for a particular purpose. KnurlPad relies on macOS trackpad hardware and system frameworks; a future macOS update may affect its behavior. You use it at your own risk.

Limitation of liability

To the maximum extent permitted by law, Kevin Tang is not liable for any indirect, incidental, or consequential damages arising from your use of, or inability to use, the app.

Changes

These terms may be updated over time. The current version will always be posted on this page with a new date.
