During installation, Kolo confirms your email address. This is the only time any information is transmitted from the Kolo VSCode extension to our servers (only your email address is transmitted). Everything else such as your code, or any runtime data stays on your machine and is not transmitted anywhere.
The data Kolo collects at runtime is stored in a local SQLite database on your machine. This same SQLite database is then accessed by the VSCode extension to power all of Kolo’s functionality.
