Your email stays private

This is the whole policy. It fits on one screen because the data fits on one row.

What we collect

An email address and an optional field for your stack. That is the whole dataset.

What we use it for

We email you about CRUX builds. Only about CRUX. Nothing else.

What we never do

We never sell your address. We never share it. We never add you to third party lists.
