FoShow End User Licence Agreement

Last updated 14 November 2026

This agreement is between you and Matthew Knerr, an individual developer in Indiana, USA ("the Developer", "I", "me"). It covers the FoShow app for Mac, iPhone and iPad, its in-app purchases, and its updates (together, "the App"). By installing or using the App you agree to it. If you don't agree, don't use the App.

1. Licence

I grant you a non-transferable licence to use the App on any Apple-branded device that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions. The App can also be used by other accounts associated with you through Family Sharing or volume purchasing where the App Store allows it. The App is licensed, not sold; I keep all rights not expressly granted here.

You may not copy (except as the Usage Rules allow), modify, reverse engineer, decompile or disassemble the App, attempt to derive its source code, or rent, lease, lend, sell, redistribute or sublicense it, except where applicable law expressly permits it despite this restriction.

2. In-app purchases

The App is free to download. Optional one-time purchases (Remove Watermark, the Pro Pack, and Full Unlock, which includes both) are sold and processed by Apple and unlock features in the App for as long as your Apple ID owns them. Refunds are handled by Apple under its policies.

3. Your content and your show

You are responsible for the media you play with the App and for having the rights to show it. The App is a tool for live production; you are responsible for testing your setup before a live event and for having a fallback. Lockout and the other safety features reduce the risk of mistakes but cannot remove it.

4. NDI® software

The App includes software from Vizrt NDI AB and its licensors ("NDI Software"), used to send video and audio over NDI. With respect to the NDI Software:

You may not modify the NDI Software, the NDI SDK, NDI products or any part of them.
You may not reverse engineer, disassemble or recompile, or attempt to reverse engineer, disassemble or recompile, the NDI Software, the NDI SDK, NDI products or any part of them, or any protocols they use, whether transmitted or received over a network or used inside or outside the machine, physical or virtual, they run on.
You may not circumvent any technical limitation in the NDI Software, the NDI SDK or NDI products.
You may not remove, obscure or alter any proprietary notice or label in or on the NDI Software, the NDI SDK or NDI products.
NDI and each of its licensors make no warranties of any kind, express or implied, about the NDI Software, and all such warranties are disclaimed. To the extent permitted by applicable law, NDI and its licensors are not liable for any damages, whether direct, indirect, incidental or consequential, arising from the use of the App or any product bundled with it.
You must comply with all relevant export laws and regulations of the United States so that the App, or any part of it, is not exported, directly or indirectly, in violation of United States law.
If you develop a product that uses the NDI Software through the App, you must comply with the terms of the NDI SDK licence, including keeping that product fully compatible with NDI, and must include the terms of this section in your own end user licence agreement.

NDI Software: Copyright © 2023–2026 Vizrt NDI AB. All rights reserved. NDI® is a registered trademark of Vizrt NDI AB. FoShow is not a product of, or sponsored by, Vizrt NDI AB. Notices for the third-party libraries included in the NDI Software are in this file.

5. Warranty

To the maximum extent permitted by law, the App is provided "as is" and "as available", with all faults and without warranty of any kind, and I disclaim all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy and non-infringement. I do not warrant that the App will be uninterrupted or error-free.

If the App fails to conform to any warranty that cannot be excluded under applicable law, you may notify Apple, and Apple will refund the purchase price, if any, that you paid for it. To the maximum extent permitted by law, Apple has no other warranty obligation of any kind with respect to the App.

6. Limitation of liability

To the extent not prohibited by law, I will not be liable for any personal injury or any incidental, special, indirect or consequential damages, including loss of profits, loss of data, business interruption, or a failed or interrupted show, arising out of or related to your use of or inability to use the App, however caused, even if I have been advised of the possibility of such damages. My total liability for all damages will not exceed the amount you paid for the App and its in-app purchases, or fifty US dollars, whichever is greater.

Some jurisdictions do not allow these exclusions or limits, so some of them may not apply to you.

7. Apple

You and I acknowledge that:

This agreement is between you and me only, not with Apple, and I, not Apple, am solely responsible for the App and its content.
I am solely responsible for any maintenance and support of the App. Apple has no obligation to provide any.
I, not Apple, am responsible for addressing any claims by you or a third party relating to the App or your possession and use of it, including product liability claims, claims that the App fails to meet any legal or regulatory requirement, and claims under consumer protection, privacy or similar laws.
If a third party claims that the App or your possession and use of it infringes their intellectual property rights, I, not Apple, am solely responsible for the investigation, defence, settlement and discharge of that claim.
You represent that you are not located in a country subject to a US Government embargo or designated by the US Government as a "terrorist supporting" country, and that you are not on any US Government list of prohibited or restricted parties.
You must comply with any applicable third-party terms when using the App.
Apple and its subsidiaries are third-party beneficiaries of this agreement, and once you accept it, Apple has the right (and is deemed to have accepted the right) to enforce it against you as a third-party beneficiary.

8. Ending this agreement

This agreement lasts until you or I end it. Your rights under it end automatically if you break any of its terms. When it ends you must stop using the App and delete it.

9. Governing law

This agreement is governed by the laws of the State of Indiana, USA, without regard to its conflict-of-law rules, except where the law of the country you live in requires otherwise. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

10. Changes

I may update this agreement. The new version will be posted here with a new date, and continuing to use the App after that means you accept it.

11. Contact

Questions, complaints or claims about the App can go to Matthew Knerr, Indiana, USA, at support@foshow.app, or through help.foshow.app.
