uninstall.ps1

Rama main · réplica de lectura del repositorio original.

#
# Uninstaller for the bare-metal Windows install. Everything Jun
# created lives either in this folder or as a normal app under
# Settings > Apps, so removal is:
#   1. stop the running processes (start.ps1 stop)
#   2. optionally uninstall Ollama / llama.cpp (machine-wide apps)
#   3. take Jun's local certificate authority back out of your
#      Windows trust store, if start.ps1 put it there
#   4. delete this folder (webapp, PHP, TTS venv, model weights,
#      chat data)
#
# git (and Python, if voice or asset recovery installed it) are
# left alone. They are general-purpose tools you may use
# elsewhere. Remove them yourself from Settings > Apps if you
# want.
#
#   ./uninstall.ps1              # interactive
#   ./uninstall.ps1 -Yes         # no prompts
#     Stops services, removes llama.cpp and Ollama if present
#     (including Ollama's %USERPROFILE%\.ollama model store),
#     then deletes this folder.
