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").
There are two ways to request deletion:
- Delete from within the app (recommended, takes effect immediately): 設定 (Settings) → おとなのメニュー (Adult Menu) → アカウント連携（保護者向け） (Account Linking, for guardians) → アカウントを削除する (Delete account)
- Request deletion by email: info+walking_bingo@oysk2.com (for users who have already uninstalled the app, or who cannot use the in-app option)
The in-app flow shows a guardian confirmation screen twice — a simple addition problem with four answer choices. It exists so that deletion is not carried out by a child alone. Choosing the correct answer continues the flow.
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.
- Launch Walking Bingo (おさんぽビンゴ).
- Open the 設定 (Settings) tab at the bottom of the screen.
- Near the bottom of the list, tap おとなのメニュー (Adult Menu).
- Guardian confirmation (1st time): a dialog titled おうちのひとにきいてね ("Ask a grown-up") shows an addition problem such as
3 ＋ 5 ＝ ？. Tap the correct answer among the four choices to continue.
- Open アカウント連携（保護者向け） (Account Linking, for guardians).
- 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).
- Guardian confirmation (2nd time): the same kind of addition problem appears again. Tap the correct answer.
- 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).
- Second confirmation dialog — 本当に削除しますか？ ("Are you sure?"): tap 削除する (Delete).
- 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 any point, or close the addition problem without answering it, 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, 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 anonymous account on our servers automatically the moment you open the public gallery, even if you have not linked a Google or Apple account. That anonymous account contains no name and no email address. It can be deleted with exactly the same steps as in section 2 above.
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.
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)
- 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)
5. Data That Becomes Unpublished
- Cards that are published or awaiting review are set to a suspended state and no longer appear in the public gallery.
- 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.
- Email correspondence: your messages remain on the mail server as a record of the inquiry.
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.
