We disclaim all warranties including merchantability, fitness for a particular purpose, and non-infringement.
To the fullest extent permitted by law, Crafter Apps shall not be liable for any indirect, incidental, consequential, or punitive damages.
Where the law permits a monetary limitation, total liability will not exceed the amount you paid for the App.
