These Terms and Conditions (“Terms” or “Custom EULA”) govern your use of the Sonic Logic, Knob Lab 3, and Sonic Logic Central applications (collectively, the “Licensed Applications” or “Apps”) developed by Uri Nachmias operating as Sonic Logic Apps (“Application Provider,” “we,” “us,” or “our”).
This Custom EULA supplements and works in conjunction with Apple’s Licensed Application End User License Agreement. By downloading, installing, or using any of our Apps, you agree to be bound by both these Terms and Apple’s standard terms.
You and Sonic Logic Apps acknowledge that this Custom EULA is concluded between you and Sonic Logic Apps only, and not with Apple. Sonic Logic Apps, not Apple, is solely responsible for the Licensed Applications and their content.
Subject to the terms of this Custom EULA, Sonic Logic Apps grants you a limited, non-exclusive, non-transferable, revocable license to use the Licensed Applications on any Apple-branded products that you own or control and as permitted by the Usage Rules set forth in the App Store Terms of Service.
You may not:
The Apps include third-party software and content, such as open-source libraries, fonts and machine-learning models, which are licensed under their own terms and listed in each App’s Acknowledgements. Those components are provided under their own licenses, and nothing in these Terms limits your rights under those licenses.
Sonic Logic is a commercial application requiring purchase before use. All sales are final except as required by applicable law or Apple’s refund policies.
Knob Lab 3 is offered as a freemium application with optional in-app purchases that unlock additional functionality.
Sonic Logic Central is provided free of charge, with no purchase required and no in-app purchases.
In-app purchases are processed through the Apple App Store and are subject to Apple’s terms and conditions.
Our Apps that function as Audio Unit extensions are intended for use within compatible Digital Audio Workstation (DAW) host applications. Proper functionality requires a compatible host application, which is not provided by us.
Where an App asks for your consent, it collects crash reports and usage statistics only after you agree, as described in our Privacy Policy. You can withdraw your consent at any time in the App’s Settings (in Sonic Logic Central, from the Log Reporting button).
Sonic Logic Apps is solely responsible for providing maintenance and support services for the Licensed Applications. Apple has no obligation whatsoever to furnish any maintenance and support services with respect to the Licensed Applications.

Sonic Logic Apps warrants that the Licensed Applications will perform substantially in accordance with their documentation for a period of 90 days from the date of original purchase.
EXCEPT FOR THE LIMITED WARRANTY ABOVE, THE LICENSED APPLICATIONS ARE PROVIDED “AS IS” AND “AS AVAILABLE,” WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, SONIC LOGIC APPS DISCLAIMS ALL WARRANTIES, EXPRESS, IMPLIED, OR STATUTORY.
In the event of any failure of the Licensed Application to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for the Licensed Application. To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the Licensed Application.
You and Sonic Logic Apps acknowledge that:
You and Sonic Logic Apps acknowledge that, in the event of any third-party claim that the Licensed Application or your possession and use of that Licensed Application infringes that third party’s intellectual property rights, Sonic Logic Apps, not Apple, will be solely responsible for the investigation, defense, settlement, and discharge of any such intellectual property infringement claim.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL SONIC LOGIC APPS BE LIABLE FOR ANY SPECIAL, INCIDENTAL, INDIRECT, OR CONSEQUENTIAL DAMAGES WHATSOEVER ARISING OUT OF OR RELATED TO YOUR USE OF OR INABILITY TO USE THE LICENSED APPLICATIONS.
In no event shall Sonic Logic Apps’ total liability to you for all damages exceed the amount paid by you for the Licensed Application.
You may not use or otherwise export or re-export the Licensed Applications except as authorized by United States law and the laws of the jurisdiction in which the Licensed Applications were obtained.
You represent and warrant that:
You and Sonic Logic Apps acknowledge and agree that Apple, and Apple’s subsidiaries, are third-party beneficiaries of this Custom EULA, and that, upon your acceptance of the terms and conditions of this Custom EULA, Apple will have the right (and will be deemed to have accepted the right) to enforce this Custom EULA against you as a third-party beneficiary thereof.
This Custom EULA is governed by the laws of the State of California, United States, without regard to its conflict of law provisions.
We reserve the right to modify these Terms at any time. Continued use of the Apps after changes constitutes acceptance of the modified Terms.
If any provision of these Terms is found to be unenforceable, the remaining provisions shall continue in full force and effect.
These Terms, together with our Privacy Policy and Apple’s standard terms, constitute the entire agreement between you and Sonic Logic Apps regarding the use of the Licensed Applications.
