Concepts Refinery is a small independent company that builds focused apps and games. We would rather make a simple tool that does one job well than another bloated platform, and we think what you put into an app should stay yours.
So our apps are designed to work without accounts and keep your content on your device. By default they include no analytics, tracking, or behavioral advertising, and any app that works differently says so in its store listing and App Data Schedule. Where it makes sense, pricing stays straightforward: paid apps are a one-time purchase unless the listing says otherwise.
