Looks like its being recreated by the first three employees at r/newsecretsanta (https://old.reddit.com/r/newsecretsanta/)
Their App Store privacy report, as well as the app developer's explicit privacy policy, directly contradicts you. Could you kindly back that up with some evidence, or is this more FUD from you?

The developer specifically states that they perform no user-linked tracking with their app. Their monetization model also supports this conclusion.
