To clarify, none of the communication with your coach happens via the Trustle website.
The part that is full of the standard instrumentation and analytics, as you point out, is our onboarding flow. The info you enter here is - who you are, - when you can talk, - and what parenting challenges you face at the broadest level.
Those are the questions required to match you with your coach. The data in those initial three questions flows into Segment and from there into our analytics tools (Amplitude, Google Analytics, conversion tracking for ads, etc.). And while it's all encrypted, etc., you're right to say that it goes to a lot of places internally. We will not ever sell that info, but analyzing it using modern tools internally helps us understand what our users want and how we can do better.
What comes afterwards is end-to-end encrypted conversation with your coach.
