Privacy & data handling

Tentaco runs this tool in your browser whenever possible. Text and structured input you paste are handled in the page session unless the tool explicitly fetches remote data. Close the tab or clear the page after use on shared computers. Features that call external APIs (such as URL fetchers) only send the data required for that request.
