Account Deletion Request

1. Applicable App

This page explains how to delete your account and the data associated with it for the mobile app おさんぽビンゴ (Walking Bingo), provided by Kyohei Takeshita (the "Service Provider").

2. Deleting from Within the App (Recommended)

This option is available while the app is installed. It is the fastest and most reliable method. It also works if you have not linked a Google or Apple account (see "2.1 If You Have Not Linked an Account").

The app interface is provided in Japanese only. Each step below gives the exact Japanese label shown on screen, followed by its English meaning.

1. Launch Walking Bingo (おさんぽビンゴ).
2. Open the 設定 (Settings) tab at the bottom of the screen.
3. Near the bottom of the list, tap 保護者向け設定 (Guardian Settings).
4. Open アカウント連携（保護者向け） (Account Linking, for guardians).
5. Near the bottom of that screen, under the heading アカウントの削除 (Account deletion), tap アカウントを削除する (Delete account).
6. First confirmation dialog — アカウントを削除しますか？ ("Delete your account?"): tap 削除にすすむ (Proceed to deletion).
7. Second confirmation dialog — 本当に削除しますか？ ("Are you sure?"): tap 削除する (Delete).
8. The message 削除しました ("Deleted") confirms that the deletion is complete.

Once you confirm, you are signed out immediately and the data listed in section 4 is deleted from the server. If you cancel at either confirmation dialog, nothing is deleted.

About the hiragana display mode: when the app's "ひらがなモード" (hiragana mode) setting is on, the labels above appear in hiragana (for example, 保護者向け設定 becomes おうちのひとのせってい, アカウント連携（保護者向け） becomes アカウントれんけい（ほごしゃむけ）, and アカウントを削除する becomes アカウントをさくじょする). The position and order of the items do not change.

2.1 If You Have Not Linked an Account

The app creates an account on our servers when you tap クラウド機能をONにする (Turn on cloud features) on the アカウント連携（保護者向け） (Account Linking) screen, or when you link a Google or Apple account. The account created in the first case is anonymous: it contains no name and no email address. It can be deleted with exactly the same steps as in section 2 above. No other action creates an account on our servers — in this version the public gallery is still in preparation, so browsing the gallery does not create one.

If no account has been created on our servers yet, tapping アカウントを削除する (Delete account) shows 削除するデータはありません ("There is no data to delete"). In that case there is nothing on the server to delete.

3. Requesting Deletion by Email

If you have already uninstalled the app, or if you are unable to use the in-app deletion option, you may request deletion by email.

• To: info+walking_bingo@oysk2.com
• Subject: アカウント削除リクエスト（おさんぽビンゴ） / Account deletion request (Walking Bingo)

Please include the following in the body of your email:

• The email address you use to sign in to the app
• Your sign-in method (for example, Sign in with Apple, or Sign in with Google)
• The device you use (iOS / Android)
• If you submitted any card for publication, the title of that card (optional)

Identity verification: To prevent someone else's account from being deleted by mistake, please send your request from the email address you use to sign in to the app. If we cannot verify that you are the account holder, we may ask for additional information, or we may be unable to fulfill the request.

If you have not linked an account: an anonymous account holds no name, no email address, and nothing else that identifies you. We therefore cannot determine which account an email request refers to, and we cannot fulfill such a request by email. Please use the in-app steps in section 2 instead.

4. Data That Is Deleted

When your account is deleted, the following data is deleted from our servers.

• Custom bingo cards saved to the cloud (including card titles and the contents of each square, and including cards imported from the public gallery)
• Account link information (the identifier received from your sign-in provider, such as Apple or Google). If you used Sign in with Apple, we also ask Apple to revoke the tokens issued for this app as part of the deletion, so the app is removed from Settings > your name > Sign-In & Security > Apps Using Apple Account on iOS. You do not need to do anything yourself.
• Login session information (tokens used to keep you signed in)
• Streak records (the record of the days you went for a walk)
• Card import history (the record of cards published by other users that you imported)
• Drawings stored on our servers (the uploaded image files used for card squares, together with their stored records. Photos are never sent to our servers, so they are not included here.)

5. Data That Becomes Unpublished

In this version (v3.0.0) the public gallery is still in preparation and cards cannot be published, so no card can be published or awaiting review. Once the publishing feature becomes available, it will be handled as follows.

• Cards that are published or awaiting review are set to a suspended state and no longer appear in the public gallery. The published record itself (the card title and the published contents of each square) is not deleted; it is retained as a record of the suspension (see "6. Data Retained After Deletion").
• However, copies of a card that other users imported to their own devices before it was suspended remain on those users' devices. We are not able to withdraw those copies.

6. Data Retained After Deletion

The following is retained after account deletion, in order to prevent abuse and to keep records required by law or by our terms.

• A minimal record that the account has been deleted (an internal identifier and the deletion status): retained so that duplicate deletion requests are not processed twice and so that completion of the deletion can be confirmed. Information that identifies you personally (such as sign-in information) is deleted as described in section 4.
• Records of consent to the User-Generated Content (UGC) Terms of Use: retained as a record of the fact that consent was given.
• Reports submitted by other users: retained in order to handle inappropriate content, prevent recurrence, and respond to disputes.
• Records of publications that were suspended, and the history of their state changes (the public card ID, the published title and square contents, the time of suspension, and the state-change history): retained so that we can confirm the withdrawal was carried out correctly, prevent recurrence, and respond to disputes. The card itself, as stored on your device and in the cloud, is deleted as described in section 4.
• Email correspondence: your messages remain on the mail server as a record of the inquiry.

Separately, usage data (anonymous interaction logs sent to help us improve the app) is never linked to your account in the first place, and is therefore outside the scope of account deletion. To stop it, go to 設定 (Settings) → 保護者向け設定 (Guardian Settings) and turn off 利用状況データの送信 (Send usage data). Once it is off, a new identifier is used from that point on, unconnected to any earlier records.

7. Data This Deletion Does Not Cover (On-Device Data)

Most of Walking Bingo's game data is stored on your device, not on our servers. The deletion described on this page covers account data on the server; data stored on your device is not deleted.

• On-device data such as ongoing and past bingo records, photos taken in the app, the collection book, and app settings
• Photos saved to your device's photo library

On-device data is removed when you uninstall the app. Photos already saved to your photo library must be deleted from your device's Photos app.

8. How Long Deletion Takes

• Deletion from within the app: takes effect immediately when you confirm.
• Deletion requested by email: we complete the deletion within 30 days at the latest, counted from the point at which we are able to verify your identity. We will reply to the email address you contacted us from once the deletion is complete.
• Copies in backups: copies contained in backups kept for disaster recovery are erased as the backup retention period (up to 30 days) elapses. During that period, data in backups is not used to provide the service.

9. Please Note

• Account deletion cannot be undone. Deleted cards and streak records cannot be restored.
• You may sign in again with the same sign-in method after deletion, but a new account will be created and the deleted data will not be restored.
