We do collect info about app usage, things like which buttons users click. This allows us to focus development time on improving the features that are used most often.
That being said, it's important to us that there is a way to be totally telemetry-less if users don't want any information to be leave their computer. Compared to most other cloud-based sass data science tools where you pretty much have no hope of total privacy, we're proud of the flexibility that we offer.
But of course, we're always open to feedback about how we can continue to improve our practices!
