Overview
DuoXO is a tic-tac-toe game for Android and iOS. You can play without creating an account. Core gameplay, local statistics, settings and progress work on your device. Available features and data processing depend on the version you install. We update this policy when our practices change.
Information stored on your device
DuoXO stores game statistics, settings, language, sound and vibration choices, theme choices, privacy choices, and locally cached Premium ownership on your device. We do not offer a DuoXO account, cloud save, or cross-platform synchronization. Deleting app data or uninstalling the game can remove locally stored data. Your operating system may include app data in device backups under its own settings.
Optional gameplay analytics
Gameplay analytics are off unless you allow sharing. When enabled, Google Analytics for Firebase can receive game events and technical information such as app version, device type, operating-system version, language, engagement data, approximate location inferred from network information, and an app-instance or installation identifier. Our gameplay events are designed to measure game starts, completed rounds, selected modes and difficulty; they do not include player names, email addresses, messages, or payment-card information. Enabling sharing does not upload earlier local game history.
Optional crash reporting
Crash reporting is a separate choice and is off unless you allow it. When enabled, Firebase Crashlytics can receive crash stack traces, technical logs, app and operating-system versions, device information, and installation identifiers to help diagnose failures. The service can retain diagnostic reports locally before upload is allowed. Turning this choice off stops future reporting through the game controls; it does not automatically delete reports already received.
Advertising and privacy choices
When advertising is enabled in a public release, DuoXO uses Google AdMob and the Google Mobile Ads SDK. Interstitial ads may appear only at natural breaks after completed rounds, subject to the game’s frequency limits. Advertising services can process IP addresses, approximate location, device or advertising identifiers, ad views and interactions, and technical diagnostics to deliver, measure, prevent fraud, and maintain advertising services.
Advertising choices are separate from the optional analytics and crash-reporting choices. Where required, an advertising consent message and privacy options let you review or change applicable choices. Some limited advertising processing may occur without personalised-ad consent where permitted. Device advertising and tracking controls can also apply. DuoXO does not request access to the iOS advertising identifier without the required platform permission.
Premium purchases
When Premium purchases are enabled, Apple App Store or Google Play processes payment for a permanent, platform-specific Premium purchase. Unity In-App Purchasing connects DuoXO to the relevant store to check product availability, localised price, transaction status, ownership, and eligible restoration. Transaction information and receipts can be processed for those purposes. We do not receive your full payment-card details. Refunds and purchase history are managed by the relevant store. Premium ownership is not shared between platforms.
Support and information you send us
If you contact support, we receive your email address, message, and any screenshots or technical information you choose to send. We use those details to answer your request and investigate problems. Please do not send passwords, full payment details, or unnecessary sensitive information.
For gameplay help, bug reports, privacy requests, or data questions, contact leandrorlls@gmail.com. Include your platform and app version when reporting a problem.
Why information is processed and who receives it
We use local data to provide the game and purchased features, consent-based analytics to improve DuoXO, consent-based crash reporting to diagnose failures, advertising data under the choices and legal grounds that apply in your region, and support correspondence to answer requests and protect the service. Service providers can include Google (Firebase and AdMob), Unity In-App Purchasing, Apple, Google Play, and our website hosting provider. Providers may process information for their own services as described in their policies.
Retention and international processing
Local game data remains until you clear it, remove the app, or your device removes it. We keep support correspondence only as needed to resolve requests and meet applicable obligations. Google, Unity, Apple, and Google Play apply their own retention rules to information they process. Service providers may process information outside your country, including in the United States, using applicable safeguards.
Your choices and rights
In DuoXO Settings, you can change analytics and crash-reporting sharing independently. Where required and available, use advertising privacy options to review or withdraw advertising choices. You can also manage advertising identifiers through Android settings and tracking permissions through iOS settings. Depending on your location, you may have rights to access, correct, delete, restrict, object to processing, receive a portable copy, withdraw consent, or complain to a supervisory authority. Email us to make a request; we may need limited information to verify it.
Children and families
DuoXO does not ask for a name, date of birth, or player account. Parents and guardians should supervise purchases, advertising, and device settings for children. We do not knowingly request personal information directly from children through the game. If you believe a child provided personal information to us, contact us so we can investigate.
This website and policy updates
This page does not include advertising, Firebase Analytics, or a contact form. The hosting service may process ordinary request information, such as IP address and browser details, to serve and secure the page. External links have their own privacy practices. We may revise this policy as DuoXO changes; the updated date appears at the top.
