This privacy policy is incomplete. You are collecting PII (the IP
address of users of the program, not just the website visitors), but
there is no data protection officer defined, no contact address for
enquiries, etc. As you probably have users in Europe, the GDPR apply,
and this is a violation.

Collecting PII needs a legitimate reason, and the one stated here "we
like to have numbers of users" sounds nice to have, but I really don't
see it outweighing the interest of the user to remain private.

TBH, you are on very slippery ground here and would be far better off
by turning this off for legal reasons.

As already mentioned, there is the Debian popularity contest (which is
opt-in), and it does have visidata numbers:

https://qa.debian.org/popcon.php?package=visidata

This is how this works in Debian. Please you can keep the feature, but
make it opt-in.

There is no written policy for this yet, but every other package I
know with such a feature has turned it off in the packaging.

Thanks.
