Privacy policy

1. Operator and privacy contact

Fouring Block is operated under the registered business name CAVE STUDIO. The representative personally handles privacy enquiries, rights requests and deletion requests through CAVE STUDIO Support.

Email: cavegames4592@gmail.com

2. Scope

This policy covers the Fouring Block Android game and support website operated by CAVE STUDIO. Ordinary play works offline. Google saves, leaderboards and cash purchases are optional features. Google Play and RevenueCat verify and restore purchases. The current distribution uses test ads and does not provide a proprietary game server, daily challenges or versus play.

Age admission occurs before the game and external services start. Players under 14 are not admitted. Items granted for watching ads and border/palette unlock counters form part of game progress.

3. Information and purposes

• On-device progress: Progress, scores, game name, settings, currency, items, cosmetics, resumable games and reward-deduplication records support gameplay and restoration. Account-specific and conflict copies may remain on the device.
• Optional Google saves: A progress copy associated with your Play Games player ID, save time and revision information is sent to Google Saved Games for cross-device restoration. Your Google player name may be used as the default game name. Depending on your device’s Play Games settings, platform authentication may occur automatically at launch; this is separate from connecting progress saves. After connecting saves, changes may sync automatically. You can pause syncing on this device in settings. Save copies do not include authentication tokens, raw purchase receipts, diagnostic logs or the device-specific score queue.
• Support: Your sender email, message and attachments you choose to provide are used to respond, solve issues and handle rights requests. Do not send passwords, verification codes, identity documents, card numbers or purchase tokens.
• Optional diagnostics: App diagnostics are stored locally when enabled, not automatically uploaded to support. We use only material you choose to export and send for support.
• Leaderboards: Classic and Time Attack scores are submitted to Google Play Games for the connected game account. Score submission is separate from restoring saved progress.

Ad reward records: Granted items, separate border/palette counters and unlocks, and the latest reward-deduplication identifier are stored as local game progress and included in the progress copy when Google saves are connected. This app-generated reward identifier is separate from advertising SDK user identifiers. The exact age and birth date are not stored. Only game admission eligibility is kept separately on the device and is not included in Google progress copies.

4. Ads, purchases and external services

The Google Mobile Ads SDK may process IP address and approximate location, ad/app interactions, performance and error diagnostics, and identifiers such as advertising ID and app set ID for advertising, analytics and fraud prevention. Test ads do not mean that no information is processed. You can manage advertising ID choices in Android settings. App diagnostics and ad SDK diagnostics are separate.

Google Play processes payments; the app does not receive your card number. Product lookup, purchase and restoration may involve product identifiers, purchase status, tokens and order references. Restoring game progress is separate from restoring purchases. Deletion is not cancellation or a refund.

Google services provide saves, ads and payments; support correspondence is handled through Gmail. The support website is hosted on Cloudflare Pages; Cloudflare may process IP addresses and request/connection information for delivery and security. The document files contain no login, analytics scripts, ads or web input forms, and host their own font.

Google Privacy Policy · Cloudflare privacy information

Purchase verification: RevenueCat, Inc. receives a purchase identifier derived from the Google game account ID, products, purchase status/history and transaction information including Google purchase tokens. These support entitlement checks, restoration, fraud prevention and purchase analytics. The SDK may process device/OS information. Communication can also occur when refreshing an identified account’s entitlements, before pressing Buy. The app does not set email or game name as RevenueCat customer attributes; optional diagnostics and automatic attribution-identifier collection are disabled. Purchase processing remains enabled.

Restoration: Purchases stay with the original Google game account. On another device, use that game account and the purchasing Google Play account. Purchases are not automatically transferred to a different game account. Contact support before paying again if restoration fails.

RevenueCat privacy information · RevenueCat Data Processing Addendum

Play Games diagnostics: The Google Play Games SDK may also collect analytics and diagnostic information automatically for service stability and improvements, independently of the game’s optional local diagnostic setting. Visibility of the game profile, including gamer name and scores, follows the settings selected in Google Play Games. Play Games data handling

Data in transit: Google Play Games documents HTTPS, Google Mobile Ads documents TLS, and RevenueCat documents encrypted transmission. This does not mean all device records or support material are end-to-end encrypted. Support email is drafted and sent by the user in their chosen external mail app; the game does not send it automatically.

5. Retention and disposal

• Device data: Retained until app data is cleared on each device. A remaining Google copy may restore progress.
• Google game data: Managed and deleted through Google's procedures for the individual game. Pausing sync does not erase existing saves.
• Support correspondence: Our retention standard is one year after resolution. Following a deletion request and appropriate verification, we delete material without an applicable reason to retain it. Where separate retention is required, we explain the relevant data, basis and duration.
• External service data: Google, RevenueCat and Cloudflare apply their actual service conditions and applicable laws. Our support retention period does not govern all provider data.

We identify correspondence, attachments and staff-created copies due for disposal, delete them and clear recoverable copies such as trash. Printed copies, if any, are shredded to prevent identification. Provider backup/security retention is assessed separately. We do not confirm deletion that we cannot verify.

RevenueCat purchase records are separate from game saves. Deletion requires a separate, verified request; clearing local or game data alone does not erase all purchase-service records. Records needed to provide entitlements are retained while the service is used; verified deletion requests are handled separately. Provider legal/security retention and backup exceptions may apply and are explained with the outcome.

6. Your rights and deletion

Contact support to request access, correction, deletion or restriction of processing. We verify authority only as necessary and do not delete another person's game data based solely on a nickname or sender address. Requests from a legal representative require appropriate verification. We explain any applicable restriction or retention reason and scope.

Google saves, device progress, RevenueCat purchase records and support correspondence are stored separately. An email request alone does not let support erase your device or your entire Google account. You can read the instructions and request help without reinstalling the app.

Deletion instructions and requests

7. Protection

Access is limited to the responsible staff and necessary material, with account protection and retention-review procedures. Google handles authentication; the game does not receive your Google password. Support material is not placed in public project files, public repositories or store images.

8. Age eligibility

The service is for ages 14 and above. Admission is checked before services start, and players under 14 are not admitted. Only eligibility, not exact age or date of birth, is stored on the device and is excluded from Google progress copies. An age response is not identity verification.

9. External services and international processing

Depending on the feature, these services process information off the device and outside your country. Data is not confined to Korean servers. Provider processing locations can change.

Google LLC and relevant service entities

Play Games processes player identity, game name, progress and scores; Google Play handles payments and purchase history; Mobile Ads processes IP-derived approximate location, ad interactions, diagnostics and identifiers. Support email is received through Gmail. Processing occurs over the internet during authentication, saving, score submission, purchases, ad requests and email delivery. Google describes worldwide servers, including the United States. Account/service deletion controls and legal/security retention exceptions apply. Contact: googlekrsupport@google.com. Google policy · Retention.

RevenueCat, Inc. — United States

For purchase verification, entitlements, restoration and purchase analytics, the derived purchase user ID, products, purchase history, tokens and transaction status are transmitted through encrypted connections during account checks, purchases and restoration. Customer data is stored in United States AWS data centers. Necessary records support purchase features while used; verified deletion requests follow the individual customer deletion procedure. Contract-end return/deletion and legal/backup exceptions follow the provider DPA. Contact: compliance@revenuecat.com. Policy · DPA.

Cloudflare, Inc. — support website hosting

Opening a page sends IP and request/connection information for delivery and security. Cloudflare describes primary storage in the United States and European Economic Area, with access from other countries. Retention depends on service purposes and legal duties; we do not promise an unverified fixed number of days for this website. Contact: dpo@cloudflare.com. Cloudflare policy.

You can play ordinary games without Google saves, leaderboards or cash purchases. Pause save syncing in settings; existing data requires separate deletion. Android advertising ID controls do not stop all ad communications. You can stop visiting the website to avoid further website requests. Ask support to stop processing or delete data. Relevant save, restoration or purchase features may become unavailable depending on the request.

Processing on our behalf for saves, purchase verification and support is distinct from providers’ own account, payment and advertising processing. Publication of this policy or use of the game is not treated as separate consent where the law requires it.

10. Effective date and updates

Effective and first published on October 25, 2026 (Korea Standard Time). Changes and their effective dates will be announced on this page and through appropriate in-app notices. This document does not replace any separately required consent.
