Privacy Policy

Last updated: September 24, 2026

This policy explains how the app "Keigo Switch" (the "App") handles user information.

1. Information we collect

The App does not ask for your name, email address or any other personally identifying information, and does not require an account. The App does not send your information to any server operated by the developer.

Information stored on your device: your learning progress (score, practice streak, cleared scenarios) and your disclaimer display preference are stored only on your device. They are never sent anywhere, and you can erase them with "Reset progress" in the App or by deleting the App.
Information related to advertising: the App uses Google AdMob (Google LLC) to show ads. To serve and measure ads and prevent fraud, AdMob may collect your device's advertising identifier (IDFA on iOS, Advertising ID on Android), approximate location inferred from your IP address, device type, app usage and interactions with ads. See Google's Privacy Policy (https://policies.google.com/privacy) and "How Google uses information from sites or apps that use our services" (https://policies.google.com/technologies/partner-sites).

2. How information is used

Information stored on your device is used only to show your learning progress. Advertising information is used by Google to serve, personalize and measure ads.

3. Consent and your choices

In the European Economic Area (EEA), the UK and certain other regions, Google's consent form is shown on first launch to ask for your consent to personalized ads. You can change your choice at any time from "Ad privacy settings" on the App's home screen.
On iOS, the App may ask for permission to use your advertising identifier (IDFA). You can use the App even if you decline. You can change this in iOS Settings > Privacy & Security > Tracking.
On Android, you can delete or reset your advertising ID in Settings > Google > Ads (or Settings > Privacy > Ads).

4. Sharing with third parties

Except as required by law, we do not share your information with third parties without your consent. However, the information described in section 1 is sent to Google AdMob to deliver ads.

5. Children

The App is not directed at children under 13.

6. Contact

7. Changes

We may update this policy to reflect changes in law or in the App. We will announce significant changes in the App or on this page.
