This Privacy Policy describes how Sudoku* (also written Sudoku Asterisk) (“the App”) collects, uses, and stores information.
App: Sudoku* (Sudoku Asterisk)
Developer / legal entity: dbpq (also dbpq Inc.)
Business registration (Korea): 226-56-00915
Operator: dbpq, Saagae-ro 33, Mapo-Gu, Seoul, Korea 04179
Privacy contact: flipdvinyl@gmail.com · +82-10-5622-6348
The App is operated by dbpq (legal / trade name dbpq Inc.; Korean business registration number 226-56-00915) (“we”, “us”). These identifiers match the Google Play and App Store listings for Sudoku*.
You can play without creating an account. Optional features (sign-in, cloud backup, ranks, purchases, and online content) send limited data as described below. We do not sell your personal information and we do not use it for advertising profiles.
The App stores play data on your device (for example in local storage), including:
Uninstalling the App or clearing app data removes this local information. We cannot recover it.
If you sign in with Google or Apple, we receive an identity token and create an account identifier. We may store a provider subject ID and, when the provider sends it, an email address. We use this only to keep you signed in, link providers, and attach cloud backup and purchases to your account.
You can delete your account in the App (Profile → Delete account), or on the web without opening the App: Delete account. That removes your account record and account-linked cloud backup, synced play records, and sign-in links on our servers. If you signed in with Apple, we also revoke the Apple authorization when the required Apple API keys are configured. Store purchases remain with Apple or Google and can be restored after you sign in again. Public rank or leaderboard snapshots already written may still show a past display name until overwritten.
If you are online and use shared or synced features, the App may send:
Lifetime Pro access and Mistake+ ticket packs are processed by Apple, Google, and our billing partner RevenueCat (including web checkout where applicable). They receive the data needed to complete and manage purchases (for example transaction identifiers and entitlement status). We do not receive your full card number.
Optional sign-in uses Google and Apple. Those providers receive the data needed to complete authentication under their own policies.
If a subscription product is offered in the future, it would renew until you cancel in your store account settings.
Local data is deleted when you uninstall the App or clear app data. Account-linked server data is deleted when you delete your account, except where we must keep a limited record (for example to prevent reuse of a consumed redeem code) or where a public play snapshot is no longer tied to a live account.
To request deletion without signing in, use Delete account, in-app bug report, or Support.
The App is not directed at children under 13 (or the equivalent age in your country). Do not create an account or make purchases for a child except as allowed by your platform’s family tools and local law.
If this policy changes, we will update the date on this page. Continued use after a material change means you accept the updated policy where permitted by law.
