However, Google\nretains ownership of the actual models trained from that data. For\nmore details about the terms and conditions for data logging, see\nthe [terms for data logging](/dialogflow/docs/data-logging-terms).\n\nOnly a limited set of authorized Google employees have access to your\ndata collected by data logging. Google uses this data solely to\ntrain and improve Google products and services.\nGoogle does not use your data or any personally identifiable\ninformation contained in your collected data to target products,\nservices, or advertising towards you, your users, or your customers.\n| **Note:** Your data collected through data logging enjoys the same level of security as all other Google Cloud services. The Google security model is an end-to-end process, built over 15 years of experience and focused on keeping customers safe on Google applications like Gmail, Search and other Apps.\n\nFor more information about Google's security policies, see\n[the Google Cloud security whitepaper](/security/whitepaper).\n\nEnable and disable data logging\n-------------------------------\n\nTo enable enhanced speech models,\nyou must enable speech data logging.\nSee the\n[Speech data logging](/dialogflow/es/docs/data-logging)\ndocument for instructions on enabling and disabling data logging."]]
