Privacy Policy

Last updated: 6 September 2026

This Privacy Policy explains how the Dual Play mobile game app (the "App"), published by Md. Risul Islam Munna ("I", "me", "my") of Dhaka, Bangladesh, handles information. It applies to the App only, not to this website's host or to any third-party site the App or its ads may link to.

1. Information stored only on your device

When you first open the App it creates a random local identifier and a random display name for you (which you can change). The App also stores your settings (such as theme and toggles) and your match history — per-game wins, draws, losses, and streaks. This information:

• is kept in the App's local storage on your device;
• is not sent to me or to any server I operate;
• is shared with another player only as needed to run a local match you start (for example, your display name is shown to the opponent you connect to over Wi-Fi); and
• is deleted when you uninstall the App or clear its data.

2. Local network (Wi-Fi multiplayer)

If you choose to play a local multiplayer match, the App uses your device's local network access to discover and connect to other players on the same Wi-Fi network or hotspot. This connection is directly between the devices in the match. Game moves and your display name travel over your local network only; they are not routed through, stored on, or visible to any server of mine. Local network access is used solely for this feature.

3. Microphone (in-match voice chat)

Voice chat is an optional feature available only during a local Wi-Fi match. If you enable it, the App uses your microphone to send live audio directly to the other device(s) in that match over your local network. The microphone starts muted, you control when it is on, audio is not recorded, stored, or transmitted to any server, and the stream ends when the match ends or you turn it off. If you never enable voice chat, the microphone is not used.

4. Advertising — Google AdMob

The App is free and is funded by ads served through Google AdMob, a Google service. To show and measure ads, Google and its partners may collect and process information such as:

• your device's advertising identifier;
• general device information (model, operating-system version, language, mobile network/country);
• coarse, non-precise location inferred from your IP address; and
• ad interaction data (that an ad was shown, viewed, or tapped).

This processing is carried out by Google as described in the "How Google uses information from sites or apps that use our services" page and the Google Privacy Policy. Where required, the App presents a consent choice before personalised ads are shown. You can also limit ad tracking on your device: Settings → Google → Ads on Android lets you reset or delete your advertising ID and opt out of ad personalisation.

5. Analytics & crash reporting — Google Firebase

The App uses Google Firebase (Google Analytics for Firebase and Firebase Crashlytics) to understand how the App is used in aggregate and to diagnose crashes. This may include:

• anonymous or pseudonymous usage events (for example, which game was opened, which mode was chosen, session length);
• device and app information (model, operating-system version, app version, language, region derived from IP); and
• crash diagnostics (the state of the app when it crashed, stack traces, and device conditions at the time).

This data is not used to identify you personally and is not combined with your on-device profile. It is processed by Google as described in the Firebase Privacy and Security documentation and the Google Privacy Policy.

6. Information the App does not collect

• Your name, email address, or phone number.
• Your contacts, photos, files, calendar, or SMS.
• Precise GPS location.
• Account credentials or payment information (the App has no accounts and no in-app purchases).

7. How information is used

• To run the games, remember your preferences, and keep your local match record.
• To connect you to other players and enable voice chat when you start a local match.
• To show ads that keep the App free (via Google AdMob).
• To measure aggregate usage and fix crashes and bugs (via Google Firebase).

I do not sell your information, and I do not use it for any purpose beyond those listed above.

8. Data retention

On-device data persists until you delete it, clear the App's data, or uninstall the App. Data processed by Google AdMob and Firebase is retained according to Google's own retention policies, linked above.

9. Your choices

• Ads: reset or delete your advertising ID and opt out of ad personalisation in your device's Google settings; where a consent prompt is shown, you can decline personalised ads.
• Analytics: Android's Settings → Privacy controls (such as "Usage & diagnostics") and opting out of ad personalisation both reduce analytics signals. You can also uninstall the App to stop all processing.
• Permissions: local network and microphone access are only used for local multiplayer and voice chat; you can decline or revoke them in your device settings without affecting single-player use.
• On-device data: clear it any time from your device's App settings.

10. Children's privacy

The App does not require an account and does not knowingly collect personal information from children. Advertising is configured to request non-personalised or age-appropriate ads where required by Google Play's Families policy and applicable law. If you believe a child has provided personal information through the App, contact me and I will address it.

11. International users

The App is operated from Bangladesh. Google's ad and analytics services process data on infrastructure located in various countries. By using the App you understand that data handled by those services may be processed outside your country of residence, subject to Google's safeguards.

12. Google Play Data safety

This policy is intended to be consistent with the App's Data safety disclosure on its Google Play listing. In summary, the App's data collection is limited to: app activity and app info/performance (analytics and crash logs) and device or other identifiers (for advertising). Data is not linked to your identity by me, and is not sold.

13. Changes to this policy

I may update this policy as the App changes — for example, if a feature is added or a third-party service changes. When I do, I will update the "Last updated" date above and post the new version at this URL. Material changes may also be noted in the App or its store listing.
