OpenCode privacy concerns mount over app.opencode.ai proxy

The gap between OpenCode's marketing and its technical implementation is a major red flag for the local LLM community. The Web UI's reliance on a central proxy means sessions are never truly air-gapped without manual network intervention, while "Zen" session titling silently uploads user prompts to external servers. Maintainers' stance on data retention for free-tier models contradicts the privacy-first ethos many users expect, leading to the rise of community-led forks like RolandCode that strip telemetry and vendor the model catalog locally. For true isolation, users are forced to rely on firewalled Docker containers rather than the application's built-in settings.
