OUN has no accounts and no sign-up. We never ask for your name, email or location, and your progress stays on your device. We do measure how the game is played and which ads work, using Google and Meta services that process device information. On iPhone you are asked first, and you can say no. Details below.
There is no OUN server. Your levels, stars, lives and power charges live in your device's own storage — delete the app and they go with it. What we do collect is anonymous usage measurement through Google Firebase Analytics: which level was started and finished, stars and misses, when lives ran out, and whether a rewarded ad was watched. These records carry no name, email or address; they tell us where the game is too hard, not who you are.
The game shows rewarded ads through Google AdMob — only when you choose to watch one. To serve, measure and protect those ads, Google may process information about your device (device type, OS version, approximate location, advertising identifiers and similar). We also use the Meta SDK to see which advertising campaigns bring players to the game; it processes similar device information (Meta's privacy policy). Neither company receives your contact details.

In the EU, UK and Switzerland the game shows Google's consent screen on first launch. To change your choice later, open Settings → Privacy Options inside the game.
On iPhone and iPad, OUN asks for permission after the opening screen through Apple's App Tracking Transparency prompt. If you allow it, Google and Meta may use your device's advertising identifier to connect an ad you saw with an install — that is how we tell whether advertising is worth its cost. If you decline, the game behaves exactly the same; measurement falls back to Apple's SKAdNetwork/AdAttributionKit, which carries no personal data. You can change your answer at any time in Settings → Privacy & Security → Tracking.
OUN is not directed at children and we do not knowingly collect data from users under 13.
We hold no account, no name and no address for you, so there is no profile to hand over or erase. The usage measurement described above is not linked to your identity. If you want it stopped, decline tracking on iPhone or turn off personalised ads; for anything else, write to support@oungame.com.
We update this policy whenever a new service is added to the game. The update date appears at the top of this page.
