Privacy Policy

Effective date: October 15, 2026

This Privacy Policy explains what information the mobile app ".333 〜生涯打撃成績〜" (shown in English as "Batting Stats" or ".333 Batting Record"; the "App") collects, why, where it is sent, and how long it is kept. The App is provided by basewakamaru, an individual developer based in Japan ("we", "us").

This policy is available in Japanese, English, Korean and Traditional Chinese. The content is the same in every language; some language versions add items required by local law.

Usage data (screens viewed; actions such as saving a game, saving practice, sharing a stats image — not the content you type, such as notes or names), app instance ID, device model, OS, language, approximate country/region, and on Android the advertising ID	Collected automatically by Google Analytics for Firebase	Understanding how the App is used and improving it

App start-up time and network speed, installation identifiers, IP address, device information, carrier, country, language, network URLs (without content)	Collected automatically by Firebase Performance Monitoring	Measuring and improving performance

Your email address and message when you contact us	Your email to us	Replying to you

We do not collect camera, microphone, location, contacts or phone number data. When you create an account we may ask for the year and month you were born (Section 6). This is used on the spot to check your age and is never stored or sent anywhere.

Stats images for sharing are created on your device and handed only to the app you choose (for example LINE or X). They are not sent to our servers. Their handling there is governed by that service's terms and privacy policy. Some settings, such as the input mode, are stored only on your device.

2. Where information is sent (service providers)

The App uses the following Google services, which store and process information on our behalf. Their handling is also governed by Google's privacy policy and terms.

Service	Provider	Information sent	Where stored / processed
Firebase Authentication	Google LLC (USA)	Email address, password, user ID, IP address	United States
Cloud Firestore	Google LLC (USA)	Profile, game and practice records	Japan (Tokyo region)
Cloud Storage for Firebase	Google LLC (USA)	Profile photo	Japan (Tokyo region)
Google Analytics for Firebase	Google LLC (USA)	Usage data, device information, identifiers	United States and other countries where Google has data centers
Firebase Crashlytics	Google LLC (USA)	Crash reports, device information, identifiers	United States and other countries where Google has data centers
Firebase Performance Monitoring	Google LLC (USA)	Performance data, device information, identifiers, IP address	United States and other countries where Google has data centers
Google AdMob	Google LLC (USA)	Advertising ID (Android), IP address, device information, ad views and taps	United States and other countries where Google has data centers

Information is sent over encrypted connections (HTTPS) while you use the App. See also: Google Privacy Policy, Privacy and Security in Firebase, How Google uses information from sites or apps that use its services.

3. Sharing and sale

We do not sell personal information. Apart from the service providers in Section 2, we do not disclose personal information to third parties without your consent, except where required by law or where necessary to protect someone's life, body or property and it is difficult to obtain consent.

Google AdMob receives advertising IDs and similar information to show ads and may also use it for Google's own purposes, such as improving ads. Under some U.S. state laws this may be considered "sharing" or "targeted advertising". You can stop it as described in Section 4.

4. Ads and advertising IDs

iOS: The App does not ask for App Tracking Transparency permission and does not access the advertising identifier (IDFA).
Android: The App uses the advertising ID. You can delete or reset it in your device's Settings → Google → Ads (wording varies by device and Android version). Ads will still appear, but they will no longer be based on your interests.

You can also review and change how Google personalizes ads at Google Ad Settings.

5. Retention and deletion

Information	Retention
Sign-in account (email address, password, etc.)	Until you delete your account. After deletion it is removed from Google's systems, including backups, within 180 days. Sign-in IP addresses: a few weeks
Profile, game and practice records, profile photo	Until you delete your account (deleted from the server immediately when you do)
Usage data (Google Analytics)	User-level data: up to 14 months, according to the Google Analytics retention setting
Crash reports (Crashlytics)	90 days
Performance data (Performance Monitoring)	30–60 days
Ad-related data (AdMob)	As set out in Google's privacy policy
Emails you send us	1 year after we finish replying

How to delete

You can delete game and practice records one by one in the App at any time.
"Account" → "Delete account" in the App (version 2.3.25 or later) first asks you to re-enter your password, then immediately deletes your profile, game and practice records, totals and profile photo from the server, followed by your sign-in account.
If you deleted your account in an earlier version, or have already uninstalled the App, email us from your registered address with the subject "Data deletion request". After confirming it is you, we will delete your data within 10 days and let you know by email.
Uninstalling the App does not delete data on the server.

6. Children

Outside Japan: The App is intended for people aged 13 and over (14 and over in Korea). If your device's region is not Japan, we ask for the year and month you were born before you create an account; if you are under the required age, you cannot create an account. In that case, a parent or guardian can create their own account and record the child's stats. The year and month you enter are used only for this check and are never stored or sent.
Japan: The App is also used by youth baseball players. Children of junior high school age or younger should use the App with a parent's or guardian's consent.
Outside Japan, we do not intend to collect personal information from children under 13 (under 14 in Korea) without parental consent. If we learn that we have collected such a child's information, we will promptly delete the account and its data. Parents or guardians who believe this has happened can contact us below.

7. Security

Communications are encrypted, and data is stored encrypted on Google's services.
Passwords are managed by Firebase Authentication; we cannot see them.
Only we use the administration consoles (such as Firebase). We look at user data only when needed, for example to answer an inquiry or investigate a bug.
Some information is stored and processed in the United States and other countries outside your own (Section 2), where it may be subject to the laws of those countries, including requests from authorities. We have confirmed that Google, our service provider, has measures in place to protect personal information (data processing terms, security certifications, etc.).

8. Your rights

You can ask us to tell you the purposes of use of, give you access to, correct, add to, delete, stop using, or stop disclosing the personal information we hold about you. Much of your profile and records can be viewed, corrected and deleted directly in the App. For anything else, email us from your registered address. After confirming it is you, we will respond without undue delay as required by applicable law, free of charge. We will not treat you differently for exercising your rights.

9. Additional information for specific regions

United States

Sections 1–6 describe the categories of information we collect, the categories of third parties that receive it, retention, and children's information, as required by the California Online Privacy Protection Act (CalOPPA), state privacy laws and the Children's Online Privacy Protection Act (COPPA).
