Yes, Nova Launcher offers a free version with many features, while Nova Launcher Prime is a paid version that unlocks additional functionalities.

Nova Launcher does not require a constant internet connection for its core features, but some functionalities, such as downloading themes or icon packs, may need internet access.

Users can contact Nova Launcher support or send feedback through the app's settings, or by visiting the Nova Launcher website and accessing the support section for additional assistance.

Since Nova Launcher does not operate on a subscription basis for its Prime version, users can simply choose to uninstall the app if they no longer wish to use it, or they can disable the premium features.
