In plain English The legal text below is what governs. This summary is informal; if it conflicts with the legal text, the legal text wins. ### What you may do - **Use** Chopinly for any purpose — personally, in a studio, in a school, inside a company — free of charge. - **Modify** the source code freely. - **Self-host** it for yourself, your students or your organization. - **Distribute** modified or unmodified copies to others, keeping these terms and the copyright notices with them, and marking what you changed. - **Build products on top of it**, provided Chopinly itself is not the product you offer to others as a service. ### What you may not do - **Offer Chopinly, or a substantially equivalent fork, to third parties as a hosted, managed or SaaS service** where the service gives users access to a substantial set of its features. This is the one load-bearing limit. - **Remove or circumvent any license-key functionality** we may add. - **Strip or obscure copyright, licensing or attribution notices.** - **Use the Chopinly name or mark** for a fork. Forks need a different name. ### Termination If you violate the license, your rights end automatically. If we notify you and you cure the violation within 30 days, the license is reinstated retroactively. Repeat violations terminate the license permanently. ### No warranty The software is provided "as is." We're not liable for damages from its use, to the maximum extent the law allows. --- ## 2.
