About this template

What is this template?

This document is a software terms of use agreement specifically for the compiled executable version of an application. It is not an open-source source code license, and it explicitly limits the Corporation's financial liability to a $500 cap.

When should you use it?

Use this when distributing ready-to-run software binaries to end users while maintaining separate licenses for the underlying source code. Use a Software License Agreement instead if the software is proprietary and not part of an open-source project.

Mostly US and UK law. Some templates use general commercial terms that work across jurisdictions, and many note which law they're written for.

It depends on the situation. Templates work well for routine business agreements. For anything involving significant money, complex IP, employment, or areas you're unsure about, it's worth getting professional advice before you sign. GitLaw provides templates and tools, not legal advice.

Open any template in GitLaw and describe the change you want in the chat — 'make clause 4 mutual' or 'add a 30-day notice period', for example. GitLaw drafts the revised language and shows it as a suggested edit. You accept, reject, or keep editing from there.
