What are the terms and conditions regarding the data collected at api.atuin.sh

By default, the user's shell history is synced to a remote server

Unless they configure and run their own localhost server

Localhost server could be but is not the default when user enters

   atuin register

Instead remote server is pre-configured, asks for email, etc.

Interesting design choice

I have used SQLite to store and search history instead of Postgres

Works with Bourne shell (sh), no need for Bourne-Again shell (bash) or other larger shells

What does "magical" mean in this context
