Summary
2 Player Games: One Phone Duel works offline and does not require an account. We do not collect, store or transmit personal data to our own servers — we do not operate any. Everything you enter stays on your device.
Advertising (Google AdMob)
The app shows ads served by Google AdMob. AdMob and its partners may collect device identifiers (the Advertising ID / IDFA), coarse location derived from the IP address, and ad-interaction data to serve, measure and limit ads — under the Google Privacy Policy. In the EEA, UK and Switzerland a consent form (Google UMP) is shown before personalised ads. On iOS the App Tracking Transparency prompt is shown before any tracking identifier is used; if you decline, you still get ads, just not personalised. You can reset or disable the Advertising ID in your device settings at any time.
In-app purchases
Optional purchases (for example removing ads) are processed by Google Play Billing or Apple's App Store. We never see your payment details; the store only tells the app whether a purchase is active. If you remove ads with a purchase, no ad requests are made. Restore purchases through the store account you bought with.
Notifications
Reminders are scheduled locally on your device only if you turn them on. There is no push service and no server involved.
Children
The app is not directed at children under 13 and we do not knowingly collect personal data from children.
Data deletion
Uninstalling the app removes all locally stored data. Because we hold no copy, there is nothing further to delete on our side. To have Google or Apple erase ad or purchase records tied to your account, use the privacy controls of your Google / Apple account.
Security
Data lives in the app's private storage on your device, protected by the operating system.
Changes
If this policy changes we will update this page and the date above.
