Refunds

All sales of Twirl are final. We don’t offer refunds once a license key has been issued.

Before you buy

There is no free trial, so please check that Twirl suits your setup first:

• You need a Mac with a trackpad, running macOS 14 or later.
• Brightness works on the built-in display of a MacBook and on Apple displays. Third-party external monitors aren’t supported.
• Volume works on any output macOS can adjust in software. Some outputs, such as certain HDMI monitors and audio interfaces, have a fixed level that Twirl can’t change either.

The questions on the home page go into more detail.

If something goes wrong

Email support@twirldial.com from the address you used at checkout if you were charged more than once, if your license key never arrived, or if Twirl doesn’t work on a Mac that meets the requirements above. We’ll sort it out.

Your legal rights

Payments are handled by Dodo Payments, which is the seller on your receipt. Nothing on this page takes away rights you have under the consumer law of the place you live, where those rights can’t be waived.
