No prompt upload in this build
The delivered application fetches static HTML, code, WASM and checkpoint files from its own domain. Experiment commands run locally in a worker. It does not send prompt text, generated bytes or private memory to a model service.
Temporary session state
Model state lives in memory. The application does not save it to cookies, local storage or a backend database. A downloaded snapshot is saved only when you choose Export snapshot, and may contain your prompt or observed values.
Hosting still involves requests
Your web host can see normal requests for website assets and may retain access logs. Following a link to F2i, GitHub, ZIPP or a cited research paper sends you to another site with its own practices. Hosting-level analytics are not part of this delivered application.
Clearing your experiment
Use Stop engine or reload the page to discard the worker and its state. Reset begins a new experiment within the current session. Avoid putting sensitive information into research prototypes or exported files unless you understand where you store and share them.
