Deco Deck is made by me, David Turner. Deco Deck doesn't collect any personal data. Actually, right now it doesn't collect any data at all. If I change my mind about data collection, I'll let you know and give you the chance to opt out.
Maybe Google, Apple, or Steam do as a result of using Deco Deck, but that's between you and them.
If you subscribe to Deco Deck, or buy a lifetime pass, you'll be dealing with Google, Apple, or Steam. They will likely abuse your personal data to the greatest extent permitted by law.
