Last updated: October 31, 2026.
This list describes the third-party services used to operate Singularity Kingdom and the information involved in each service. It supplements the Singularity Kingdom Privacy Policy.
Which providers process your information depends on the features you use. Some services support the game itself; others are involved only when you choose features such as account linking, email recovery or chat translation.

App stores and linked services
Google Play distributes the Android app. Google processes information about your use of its store and services under the Google privacy policy.
When you use a provider's own account, website or app, that provider may also process information independently under its own privacy policy. Its broader privacy policy may describe services and data collection that are not used by Singularity Kingdom.
