Mobile apps

Our Android apps set no cookies — there is no browser involved. They do use the equivalent local technology: a private preferences file on the device for your settings and progress. Our ad-supported games also use the Android advertising ID for ad serving; consent for that side is collected in-app through Google's User Messaging Platform rather than through the banner on this site, and you control the identifier itself from Android's own settings. Our paid apps contain no advertising SDK and do not request the advertising ID at all. The per-app privacy policies for M. MANN, oOoOo, and CastBlast cover this in full.
