1. Basic policy
The App is designed so that the numbers you enter and the results you calculate are never saved and never sent anywhere (the App keeps no calculation history). The App communicates with outside services only to show ads, to process in-app purchases, and to record errors and usage so that we can fix problems and improve the App, as described below.
2. Information kept only on your device
The following information is stored only on your device and is not sent to us or to any third party (except as included in the reports described in Section 5).
- Your settings, such as the chosen design (theme), BGM and effect, and whether BGM, effects and sound effects are on or off
- Whether you have purchased "Remove Ads"
- On iPhone and iPad, if you updated from an earlier version, a record of whether your earlier settings have been carried over (the earlier settings are read on your device and are not sent anywhere)
3. Advertising
The App shows banner ads at the bottom of the screen using Google AdMob, an advertising service provided by Google LLC. To deliver ads, Google may collect the following information:
- Advertising identifiers (IDFA on iOS, advertising ID on Android)
- Device information such as IP address, device model, OS and language
- Information about ads, such as which ads were shown or tapped
The numbers you enter and the results you calculate are never sent for advertising.
(1) Ad consent and permission to track
For users in regions where consent is required by law, such as the European Economic Area (EEA) and the United Kingdom, the App shows Google's consent form before showing ads. You can change your choice at any time from "Settings" → "Ad privacy settings" in the App. If consent is not given, no information is sent for ad delivery.
On iPhone and iPad, the App asks, through App Tracking Transparency (ATT), whether you allow tracking of your activity across other companies' apps and websites. If you do not allow it, you can still use all features of the App (ads are still shown, but they are less likely to match your interests).
(2) How to stop personalized ads
- iPhone and iPad: turn off the App under "Settings" → "Privacy & Security" → "Tracking"
- Android: delete (or reset) your advertising ID under "Settings" → "Google" → "Ads"
- To stop showing ads altogether, use the in-app purchase "Remove Ads" (Section 4). After purchase, the App does not start the ad SDK, so the information above is not sent
(3) Google's privacy policies

- AdMob and privacy
4. In-app purchases
The App sells "Remove Ads" (a one-time purchase) that stops ads from being shown. Payments are processed by the App Store (Apple Inc.) or Google Play (Google LLC). We do not receive payment information such as credit card numbers, or the purchaser's name or contact details.
Whether you have purchased is stored on your device. When you tap "Restore purchases", the App asks the store for your purchase records. No purchase information is sent to our servers.
5. Error and usage reports
To investigate problems and improve the App, we use Firebase Crashlytics (error reports) and Google Analytics for Firebase (usage reports), provided by Google LLC. The following information is sent:
- Details of errors (where and what kind; file locations and anything you entered are removed before sending) and the screen that was open just before
- Your settings when the error occurred (the chosen design, BGM and effect, and which of them are on or off)
- Usage (screens opened, changes of design, BGM and effect and which ones you chose, settings turned on or off, and how many times you tapped the share button or the link to a recommended app)
- Device model, OS and language, app version, approximate region (country or region, estimated from the IP address), and an app instance identifier (an ID issued for each installation)
The numbers you enter and the results you calculate are not sent. Advertising identifiers are not used, and these reports are not used for advertising. We review the reports as statistics and do not use them to identify individuals.
6. Sharing and external pages
When you tap the share button in "Settings", your device's share sheet opens and passes a message introducing the App to the app you choose (such as social media or messages). Sending happens only through your own action; the App never sends anything automatically. The recipient service handles the message under its own privacy policy.
When you tap a link such as a recommended app, an external website opens in your browser. That website handles information under its own privacy policy.
7. Inquiries and this website
If you contact us by email, we receive your email address, your name (if provided), the content of your inquiry, and your device, OS and app version (if provided). We use this only to answer your inquiry and to improve the Service.
This website is served by Firebase Hosting of Google LLC. For troubleshooting and security, delivery logs (IP address, browser type, date and time of access, etc.) are recorded on Google's servers for a certain period. This website does not use cookies, analytics, ads or external web fonts.
8. Purposes of use
We use the information we obtain only for the following purposes:
- To provide, operate, maintain and improve the Service
- To respond to inquiries
- To notify you of important matters about the Service (such as changes to the terms)
- To comply with laws and regulations
We change these purposes only within a scope reasonably considered to be relevant to the previous purposes, and we announce any change on this page.
9. Provision to third parties
We do not provide personal information to third parties without your prior consent, except as required by law. Information sent for advertising (Section 3) and for error and usage reports (Section 5) is as described in those sections and in the next section.
10. Information sent outside the device (public notice under the Telecommunications Business Act of Japan)
The App sends information from your device as follows:
| Recipient | Google LLC (Google AdMob, Google User Messaging Platform) |
|---|---|
| Information | Advertising identifier, IP address, device model, OS and language, app identifier, ad impressions and taps, ad consent status |
| Purpose | Ad delivery, measurement and fraud prevention; managing consent in regions where it is required |
| How to stop | As described in Section 3 (2) (nothing is sent after purchasing "Remove Ads") |
| Recipient | Google LLC (Firebase Crashlytics, Google Analytics for Firebase) |
|---|---|
| Information | Error details (excluding what you entered), settings when the error occurred, screens opened and number of actions, device model, OS and language, app version, approximate region, app instance identifier |
| Purpose | Investigating and fixing problems; improving the App |
Google LLC is a company based in the United States, and information may be processed in the United States and other countries.
11. Security
We take necessary and appropriate measures to prevent leakage, loss or damage of personal information and otherwise to keep it secure. When we entrust the handling of personal information to others, we select them appropriately and supervise them as necessary.
12. Requests for disclosure, correction or deletion
If you request disclosure, correction, addition, deletion or suspension of use of your personal information that we hold (such as records of your inquiries), we will respond in accordance with the law after confirming your identity. Information stored only on your device (Section 2) cannot be accessed by us; please delete it yourself by deleting the App.
13. Retention and disposal
We promptly delete or dispose of personal information that is no longer needed for its purposes, in an appropriate manner that prevents leakage.
14. Changes to this Policy
We may revise this Policy in response to changes in laws or in the Service. We will announce important changes on this page or in the App. The revised Policy takes effect when it is posted on this page.
