Robonet Communications inc. ("we", "us") provides the mobile application "Japan Map Quiz" (the "App"). This Privacy Policy explains how information is handled in the App, in accordance with Japan's Act on the Protection of Personal Information ("APPI") and other applicable laws.
The App is a study tool for learning the 47 prefectures of Japan. Its primary audience is people aged 13 and over (junior high school age and above, including adults), and the target audience declared in each app store is 13 and over.
We do not restrict use by age, so younger people may also use the App; in that case it should be used under the supervision of a parent or guardian (see section 7). The design of the App and its advertising configuration assume users aged 13 and over.
The App does not collect any personally identifiable information. There is no account or sign-in. We never ask for a name, email address, password, date of birth, or phone number.
The following is stored only on your device and is never transmitted to us or anyone else. Deleting the App removes it.
The App shows advertising through Google AdMob, in three forms:
As stated in section 2, because the App is intended for users aged 13 and over, we do not enable AdMob's Child-Directed Treatment or Under Age of Consent settings. Ad content is restricted to the "T" (teen) rating or below.
To serve and measure ads, Google may process:
This information may be used to serve advertising based on your interests (personalized advertising).
Consent. In regions where consent or a choice must be offered — the European Economic Area, the United Kingdom, and certain US states — we present Google's User Messaging Platform (UMP) consent form on first launch. You can change your choices at any time from "Settings → Ad privacy settings" in the App (this item appears only in regions where the form is required).
Tracking on iOS. On iOS, we present the system App Tracking Transparency dialog before the advertising identifier (IDFA) is used. All features of the App remain available if you decline; non-personalized advertising is served instead.
See the Google Privacy Policy for details.
Ad removal is offered as a one-time (non-consumable) in-app purchase through the App Store (Apple) or Google Play (Google), with purchase state managed via RevenueCat. Payment details such as credit card numbers are handled directly by Apple/Google; neither we nor RevenueCat hold them. RevenueCat receives an anonymous user ID and the purchase receipt, only as needed to manage entitlement.
The App has no server operated by us. Map data and prefecture data are bundled inside the App, so no network request is required to use it. Your quiz answers and usage are never sent to us.
As stated in section 3, we do not collect or hold user information. Information processed by third parties (Google, RevenueCat, Apple) is limited to the following purposes:
| Service | Purpose | Scope of information | Country |
|---|---|---|---|
| RevenueCat | Purchase state management | Anonymous user ID, purchase state | United States |
Google AdMob uses information not only on our behalf but also for Google's own purposes, such as ad delivery, fraud prevention, and service improvement. This may constitute "provision to a third party" under the APPI. As described in section 3.2, the App serves ads configured for users aged 13 and over, and information including advertising identifiers may be used for personalized advertising. In regions where consent or a choice must be offered, you decide through the UMP consent form and the iOS tracking dialog.
The parties above are located outside Japan (primarily in the United States). We handle such transfers in accordance with the APPI's rules on provision to third parties in foreign countries, after confirming that they maintain appropriate protection frameworks. See:
We do not provide information to third parties except:
We never sell information in exchange for money or other consideration.
Because the App does not store user information on our servers, the risk of a leak on our side is limited. Communication with the parties above uses the encrypted (HTTPS/TLS) connections those services provide.
The primary audience of the App is 13 and over, but we do not restrict use by age. In every case, the App never asks for a name, address, phone number, date of birth, or any other personally identifiable information.
That said, the App serves advertising configured for users aged 13 and over. This includes full-screen and video ads, and personalized advertising where consent has been given. If a child under 13 uses the App, please do so under the supervision of a parent or guardian.
If you would rather not see advertising, the App offers a one-time in-app purchase that removes it. After purchase, no banner, full-screen, or video advertising is shown.
Please direct any questions or complaints about how information is handled in the App to dev@robonet-c.jp.
The map of Japan used in the App is derived from data published in "Global Map Japan" by the Geospatial Information Authority of Japan (GSI) (https://www.gsi.go.jp/kankyochiri/gm_jpn.html). That data is provided under the GSI Content Terms of Use.
We may revise this policy as needed. The revised policy takes effect when posted on this page. We will notify users within the App of significant changes.
