This Policy applies to all Android applications we publish on the Google Play Store. App-specific handling is described in Section 2 onwards.

2. Information Collected

The information collected differs from app to app. Information directly entered by users is, in principle, stored only on the user's device and is not transmitted externally. For ad delivery and crash reporting, certain user data may be transmitted externally via SDKs provided by Google (see Section 4 for details).

2-1. Information Collected per App

This table will be updated as new apps are published.

2-2. Information Commonly Collected (via Ad SDK)

For our Apps that display advertisements, the Google AdMob SDK collects and transmits the following information:

• Advertising ID (Android Advertising ID / AAID)
• IP address
• Device information (model, OS version, language, time zone)
• Approximate location (country level, based on IP address)
• App interaction and ad viewing logs

3. Purpose of Use

Pursuant to Article 17 of the APPI, we use the collected information only within the scope of the following purposes:

• To provide the functionality of our Apps (recording, displaying, and aggregating data entered by users)
• To deliver and optimize advertisements (via Google AdMob)
• To analyze and improve app stability and quality (via Firebase Crashlytics)
• To respond to inquiries
• To notify users of changes to this Policy and other communications

If we use the collected information for purposes other than those above, we will obtain the user's prior consent.

4. Third-Party Disclosure (List of Recipient SDKs)

Our Apps use the following third-party services (SDKs), and user data is transmitted to each service. In no case do we directly transmit a user's name, address, telephone number, or email address.

4-1. Google AdMob

• Provider: Google LLC
• Recipient Country: United States of America
• Information Transmitted: Advertising ID (AAID), IP address, device information (model, OS version), approximate location (country level), app interaction and ad viewing logs
• Purpose of Transmission: Ad delivery, fraud/invalid click detection, performance measurement
• Privacy Policy: https://policies.google.com/privacy
• Advertising Policy: https://policies.google.com/technologies/ads

4-2. Firebase Crashlytics

• Provider: Google LLC
• Recipient Country: United States of America
• Information Transmitted: Stack traces upon crash, device information, app identifier, Firebase Installation ID, app state
• Purpose of Transmission: Analysis and improvement of app stability and quality

If we introduce additional SDKs required for app-specific features (such as voice recognition, cloud sync, or in-app billing), we will amend this Policy and apply them only to the relevant apps.

5. Advertising

Some of our Apps display advertisements via Google AdMob. The handling of data associated with ad delivery is as described in Section 4-1.

5-1. Consent in the EU/EEA and UK (UMP)

For users in the EU/EEA and the UK, we obtain consent regarding the use of data for advertising purposes at first launch via the Google User Messaging Platform (UMP). Users may choose between "personalized advertising" or "non-personalized advertising", and may change their preference at any time via the "Reconfigure consent settings" menu within the app.

5-2. Resetting the Advertising ID

Users can reset or delete the Advertising ID at any time via "Settings → Privacy → Ads" on their Android device.

6. Handling of Sensitive Personal Information

None of our currently published apps handle information that may fall under "sensitive personal information" (要配慮個人情報) as defined in Article 2, paragraph 3 of the APPI (e.g., medical history, physical or mental disability, results of medical examinations by a physician, etc.).

If we publish an app that handles such information in the future, we will keep that information strictly within the user's device and will not transmit it to us or any third party. The amended details will be reflected in this Policy.

7. Children's Privacy

In line with the spirit of Google Play's Families Policy and the U.S. Children's Online Privacy Protection Act (COPPA), we strive to protect the personal information of children. We do not currently publish any app primarily targeting children under the age of 13.

If we become aware that a child under the age of 13 has inadvertently provided personal information, we will promptly delete it. Please contact contact@akiappsdev.com.

8. Data Storage and Retention Period

• On-device data: Completely deleted when the user uninstalls the app. We do not have any means to back up or recover such data.
• Data via Google AdMob / Firebase Crashlytics: Retained in accordance with Google LLC's data retention policies. Please refer to Google's privacy policy for details.
• Inquiry records: We delete received emails approximately one year after the inquiry has been resolved.

9. Disclosure, Correction, and Deletion Requests (APPI Articles 28–31)

Pursuant to Articles 28 through 31 of the APPI, users may make the following requests regarding the personal data we retain:

• Notification of purpose of use
• Disclosure of retained personal data (Article 28)
• Correction, addition, or deletion of retained personal data (Article 29)
• Cessation of use, erasure, or cessation of third-party provision of retained personal data (Article 30)
• Disclosure of records of third-party provision (Article 28, paragraph 5)

How to Submit a Request: Please contact contact@akiappsdev.com with the following information:

• Type of request (disclosure / correction / deletion, etc.)

Estimated Response Time: We will respond in writing or by email within two weeks (or within 30 days for complex matters) after receiving the request. Please note that the majority of our Apps store data only on the device, and the personal data we retain and manage is therefore limited.

Fees: Responding to disclosure requests is free of charge. However, if you request a written response by post, you may be asked to bear the actual postage costs.

• Where our Apps or this Policy contain links to external websites, we are not responsible for the content or privacy practices of such linked sites.
• If we publish health- or medical-related apps, they do not provide medical diagnosis or treatment and are not a substitute for medical care. Please consult a qualified medical professional for any health concerns.

16. Revision History

• 2026-05-02: Generalized scope to "all Android apps published on Google Play" and simplified app enumeration. Aligned with the launch of VoiceCalc as the sole published app: removed app-specific sections that did not apply (4-3 SpeechRecognizer, 4-4 Firebase Auth/Firestore, 4-5 Play Billing, the per-app sensitive-information enumeration, and the per-app children's-app examples). Same day, added SubFlow to Section 2-1. Added Section 12-bis (Trademarks and Third-Party Names).
• 2026-04-28: Comprehensive revision. Updated the list of provided apps to the latest 20 titles (removed GalaxyBowling / BreathCanvas / TiltTone / BeatWalk / OneSecond / IfOnly / InfiniteSudoku / InfiniteNonogram / InfiniteConnect / SyncScope; added FoodKeeper / Kakikata / TrashAlert / Nondakke / TenseiShindan / HajimeteGohan). Added new sections on sensitive personal information (Section 6), APPI Article 28 disclosure requests (Section 9), GDPR (Section 10), and security measures (Section 11). Added the business operator's address. English translation (this page) published the same day.
• 2026-04-06: Initial publication.
