Privacy notice

A quick note about privacy

Streamlit aims to make it fast, easy, and delightful to create and share apps. To do so, Streamlit has open-source software you can download to build your apps; a sharing platform you can use to deploy, manage, and share your apps; and various services, like our discussion forum, where you can get more information on how to better use Streamlit. By default, each product or service collects some data so that we can understand how Streamlit products are used and use that information to improve Streamlit.

The Streamlit open-source software does collect summary statistics. You can turn off summary statistics when using our open source software by changing your config file to set browser.gatherUsageStats = false.
