World Map Drop: USA (the United States edition of the iPhone and Android app)

Dopa Game Lab (Masato Nishikawa, "we") explains here how the game World Map Drop: USA ("the game") handles your information. The game is the United States edition of the app 新・都道府県ゲーム, shown to players of the US App Store and Google Play.

What the game collects

The game does not collect personal information such as your name, your email address or your play history. Your score and the pieces in the box are worked out on your device only, and are never sent to or stored on our servers. There is no login.

Settings kept on your device

The app keeps the following on your device: your choices for Haptics, Sound effects, Music and Effects (ON / OFF), the number of finished games, the number and time of full-screen ads shown, whether a review request is planned or done, whether the tutorial is finished, your top 3 scores (Hell Mode keeps its own top 3 and best lap), the game in progress, a copy of whether you have bought Remove Ads, a copy of the settings file read from our site, and the country of your App Store or Google Play account (to show the United States or the Japanese edition). They are used for your settings and the screen, the spacing of ads, your records and continuing a game, and are never sent to us. A game in progress can be continued after you close the app.

The store's country is read from Apple's StoreKit or Google Play Billing on your device. The app does not ask for your location.

Ads in the app

The app shows ads from Google AdMob, a service of Google LLC, at the top of the screen, on the result screen and between games (on a result screen every few games, or on a result screen or reset when some time has passed since the last ad; we adjust how often). If you buy Remove Ads (in-app purchase), no ads are shown. To show ads, Google may use information such as:

• identifiers of your device such as an advertising identifier (on iPhone, the IDFA only if you allow tracking; on Android, the device's advertising ID)
• your approximate location, as known from your IP address
• records of ads shown and tapped, and information on how the app runs (for example, to look into problems)

If you do not allow tracking, ads are still shown, but they are not ads that suit you. You can change this at any time on iPhone in Settings > Privacy & Security > Tracking. On Android, you can delete or reset the advertising ID in your device's Settings > Privacy > Ads (on some devices, Google > Ads). After you delete it, ads are still shown, but they are not ads that suit you. Where consent is needed (for example in Europe and in some US states), the app shows Google's consent screen, and you can choose again later with the gear button at the right end of the ad strip.

For how Google uses information, see Google's Privacy Policy and How Google uses information from sites or apps that use its services.

Your privacy choices in US states

We do not receive or sell your personal information ourselves. However, under the privacy laws of some US states (such as the California Consumer Privacy Act), showing ads that suit you through Google AdMob may count as "selling" or "sharing" personal information for targeted advertising. You can choose that your personal information is not sold or shared:

• Where Google says it is needed for your state, the app shows Google's privacy screen, where you can opt out of the sale or sharing of your personal information.
• You can opt out again, or change your choice, at any time with the gear button (Ad privacy settings) at the right end of the ad strip at the top of the screen. It opens Google's privacy screen.
• On iPhone you can also turn off tracking (Settings > Privacy & Security > Tracking), and on Android delete the advertising ID (see above).

After you opt out, ads are still shown, but they are not ads that suit you. You will not be treated differently in the game for making any of these choices. For any other request about your information, please contact us (below).

Ad revenue measurement and purchase checks

The app uses the services of RevenueCat, Inc. to understand how ads are used and how much they earn. It sends RevenueCat an identifier of the player that is made automatically, the kind and place of each ad, records of ads loaded, shown and tapped, and each ad's revenue and currency, which are used for counting and analysis. Information needed for the service to work, such as the versions of the app and the OS, is also sent.

You do not need to give a name or an email address for this. Your score and the pieces in the box are not sent to RevenueCat. The ads and the revenue measurement do not start during the first tutorial; they start after you finish or skip it (if you press Remove Ads or Restore Purchases during the tutorial, they start then). For details, see RevenueCat's Privacy Policy.

RevenueCat is also used to check purchases and restores of Remove Ads (in-app purchase). RevenueCat receives the record of your purchase on the App Store or Google Play (the product, the date and time, the transaction number and so on) and uses it to tell whether you have bought it. Payment is handled by Apple or Google; neither we nor RevenueCat receive payment information such as card numbers. Nothing about your games is sent.

The settings file

When it starts, the app reads a small settings file from our site (sns.dopagamelab.com) and uses it for the spacing of ads and for update notices. Nothing about you is sent with it. Cloudflare, which delivers our site, receives the usual connection information such as your IP address.

The web version

The web version (sns.dopagamelab.com, in Japanese) uses Cloudflare Web Analytics, the visit count of Cloudflare, which delivers the site. It uses no cookies and does not identify you; it only counts things like page views. The web version has no ads.

Sharing

When you press Share on X, the app hands a picture of your box and the result text to the share menu of your iPhone or Android device, or to the X post screen. The picture is made on your device. You choose where to send it, and the service you send it to handles it under its own rules. On iPhone, the app asks for permission to add to your photos only when you choose Save Image.

Changes

If we change this policy, we will say so on this page.
