In one paragraph
We don’t log what you do on the internet. We don’t record which sites you visit, the DNS queries you make, or what you upload or download — our tunnel carries your traffic without inspecting it. To run the account and keep the app working we do keep a few things — your email, your billing record, a per-install device identifier, the country you connect from, and (unless you turn it off) some product-usage and crash data. You can disable that analytics any time in the app under Settings → Privacy. The next sections list all of it, and what we deliberately never touch.
