Opt out
There is very little to opt out of, and this page says exactly what.
There is no profile to delete
No account exists, so there is nothing to close. The only row connected to you is one whose key is a hash of a code we do not have.
Nothing is collected to switch off
No analytics, no tracking cookies, no email list and no advertising identifiers. There is no setting here because there is nothing running.
If you want a pack's row removed
It can be done with the claim code, because the claim code is the only way to find it. We would rather you did not send a working code to anybody, including us, so a safe way to do this is not published yet.
