Privacy Policy for Sovereign

Last updated 1 November 2026

Sovereign is a single-player city building game. We do not collect, receive, or sell any personal information. There is no Sovereign account to create.

The game itself works entirely offline. It has no analytics, no advertising, no tracking and no crash reporting, and it never sends anything to us.

What Sovereign collects

Nothing. We have no servers and receive no data from the game.

Google Play Games (Android only)

On Android, Sovereign's milestones are also Google Play Games achievements. If you are signed in to Google Play Games on your device, the game tells Google Play Games when you earn a milestone so it can appear on your Play Games profile. That is handled by Google under the Google Privacy Policy; we do not receive your name, account or any other information from it. If you are not signed in to Play Games, nothing is sent. The iPhone version does not use it.

Ratings

After you have played for a while, the game may show the store's own rating prompt (Google Play or the App Store). That prompt is provided by the store, and anything you enter in it goes to the store, not to us.

Your saved games

Sovereign saves your towns on your own device, using your device's local browser storage. Those saves never leave the device and are never sent to us or to anyone else. We cannot read them. Deleting the app deletes them.

Children

Sovereign does not knowingly collect information from anyone, of any age, because it does not collect information at all.

Purchases

Sovereign contains no in-app purchases, no subscriptions, and no advertising. You pay once, or nothing at all, and that is the end of it.

Changes

If this policy changes, the revised version will be posted at this address with an updated date above.
