TPCurveTerms of use and licence
Last updated November 2026
These terms apply when you download, try or buy TPCurve. By using TPCurve you agree to them.
Free trial
You can use TPCurve free for 14 days on each Mac. After that, a licence key is needed to keep using TPCurve's curves. Without one, your trackpad and mouse return to macOS's own behaviour.
Your licence
- Buying TPCurve gives you a personal, non-transferable licence to use it on up to 3 Macs that you own or control.
- The licence doesn't expire. It covers the version you buy and its updates within the same major version (for example, 1.x).
- You may not share your key publicly, resell it, or modify, copy or redistribute TPCurve, or work around its licence checks.
Purchases and refunds
Purchases are processed by Polar, which acts as the merchant of record and handles payment and sales tax. If TPCurve isn't right for you, email support@tpcurve.app within 14 days of purchase for a full refund. Refunded keys stop working.
No warranty
TPCurve is provided "as is". We work hard to make it reliable, but we can't promise it will be free of errors or work with every Mac, accessory or future version of macOS. TPCurve can always be switched back to macOS's own behaviour (⌃⌥⌘M) or removed completely (Uninstall… in its menu).
Limitation of liability
To the extent the law allows, our total liability for any claim relating to TPCurve is limited to the amount you paid for it. Nothing in these terms limits rights you have under consumer protection law that can't be limited.
Changes
We may update these terms. The version on this page applies from the date shown above.
Governing law
These terms are governed by the laws of the Province of Ontario and the federal laws of Canada that apply there.
