Through the app, none. The app uses your OpenAI API key and your Gumroad license key to verify access to both of those services. License management is handled via Gumroad, their privacy policy might enlighten you further. My impression is they only require an email and some billing info (Paypal or Credit card)

I can confirm this to be true (at present).

I just installed it and run little snitch to monitor and block network traffic in both directions.

It didn't try to connect out to the internet at all until I started a new conversation thread, when it did it made two calls:

  1. Gumroad license server
  2. api.openai.com

There has not been any analytics / tracking calls such as Sentry/NewRelic/Google etc.... thus far (and I'd block them if there was).

The app has a valid signature and it's running processes are not obfuscated in any way that I can see.

Fantastic — bought a license!

Love how simple it is; exactly what I was hoping.

Do one for iOS, too! ;)
