Rin Chat License

Effective date: October 24, 2026

Rin Chat is proprietary software, provided free of charge for personal, non-commercial use.

You may:

install and use the application on devices you own or control;
back up, export, and freely use the content you create with it (your characters, chats, worldbooks, and settings are yours).

You may not:

redistribute, sell, rent, or sublicense the application or modified versions of it;
reverse engineer the application except where applicable law permits it notwithstanding this restriction;
remove or alter its notices of authorship.

A package manager or distribution may publish a recipe that downloads the official release from rin.chat and adapts it to run on their system, for example by patching library paths or adding a wrapper, only with prior written permission from Rin Chat LLC. Ask first through our contact page. Users who install Rin Chat through a permitted package are covered by this license.

Rin Chat LLC may also give a package repository written permission to host and redistribute the builds its recipe makes, for example from its binary cache and mirrors. Those builds must come from the official releases published at rin.chat, changed only as needed to run on that system, for example by patching library paths, adding a wrapper or turning off the in-app updater. This license and its notices of authorship must stay intact, and the app's usage reporting must not be removed or changed. The permission covers only the repository it is given to, and Rin Chat LLC may withdraw it for future versions at any time. Without that permission, no one but Rin Chat LLC may host or redistribute the software.
