> But since it is a electron app, it will always contact Google everytime you open the app

Do you have a source for this? I couldn't find anything about this, and I find it strange that Electron (which uses the open-source chromium engine but not Chrome) would automatically send tracking information to Google.

While this particular app may or may not send telemetry to Google, it is not correct that “all Electron apps do”, as OP suggests.
