I will develop custom rpg maker mv and mz plugins

Usually, yes, provided the modification is technically possible and permitted by the original plugin's license or terms of use. Send me the plugin and explain what you would like changed before ordering.

Possibly. Compatibility work depends heavily on how both plugins are designed. Send me both plugins, their versions, and a description of the conflict or desired integration so I can inspect them first.

Bugs directly related to the agreed functionality are covered for 30 days after final delivery. New features, changes in requirements, or conflicts introduced by later project/plugin changes may require additional work.

Yes. Unless otherwise agreed, you may use the delivered plugin in your commercial or non-commercial RPG Maker project. You may modify the plugin for use within your own project, but you may not resell or redistribute the plugin itself as a standalone product.

Standard orders are non-exclusive unless exclusivity is specifically included in your custom offer. If you require exclusive ownership or want the plugin permanently withheld from public release, tell me before ordering so we can agree on appropriate terms and pricing.

I may create a generalized version of non-exclusive work for future public release, but your project-specific content, assets, data, and confidential information will not be included. If you require complete exclusivity, please request an exclusive custom offer before ordering.
