Introduction

BUP Apps ("we", "our", or "us") respects your privacy and is committed to providing transparent information about how data is handled when you use BUP 21.

This Privacy Policy explains the information stored by BUP 21, the third-party services integrated into the application, how advertising and purchases work, and the privacy choices available to users.

BUP 21 is a single-player card puzzle game designed for entertainment and strategic gameplay. The application does not require users to create an account or submit personal identification information to play.

Core gameplay data is stored locally on the user's device. Certain optional features, such as advertisements and in-app purchases, rely on Google services that may process information according to their own privacy policies.

By using BUP 21, you acknowledge the data practices described in this policy. Where consent is legally required, it is requested separately through the appropriate consent mechanism.

1. Nature of the Game — No Real-Money Gambling

BUP 21 is a single-player card puzzle and strategy game.

Although its gameplay involves forming card combinations that total 21, BUP 21 does not provide real-money gambling services.

Specifically:

• Players cannot place real-money bets or wagers.

• The application does not accept gambling deposits or provide withdrawals.

• Players cannot win real money, cryptocurrency, physical prizes, or other rewards with real-world monetary value.

• Game scores, achievements, experience points, and virtual progression have no cash value.

• Purchased cosmetic content and Undo credits cannot be redeemed, transferred, or exchanged for money or real-world prizes.

• The application does not operate gambling tournaments, betting pools, or cash-prize competitions.

Optional in-app purchases provide digital cosmetic content, advertising removal, or limited gameplay assistance through Undo credits.

These purchases do not represent financial investments, wagers, or opportunities to receive monetary returns.

BUP 21 is intended solely for entertainment.

2. Information Stored Locally

BUP 21 stores information necessary to operate the game and preserve your preferences.

This may include:

Gameplay and progression

• Game scores and personal records.

• Completed runs and gameplay statistics.

• Experience points and progression levels.

• Missions, daily objectives, and achievements.

• Unlocked gameplay-related content.

• Game mode progress and relevant gameplay state.

Personalization

• Selected card decks and card backs.

• Selected environments and visual themes.

• Language preferences.

• Light and dark appearance settings.

• Sound effect, vibration (haptics), reduced-motion and lane-total display preferences.

Purchases and entitlements

• Ownership of permanent digital purchases.

• Remove Ads entitlement.

• Purchased Undo credit balances.

• Daily Undo allowance and usage records.

• Information needed to prevent duplicate purchase grants.

This information is primarily stored in the application's private local storage on your Android device.

BUP Apps does not require a separate user account or operate a dedicated gameplay-history server for BUP 21.

Depending on your Android settings and backup eligibility, some application data may be included in Google's Android backup system.

3. Advertising — Google AdMob

The free version of BUP 21 may display advertisements through Google AdMob.

The application uses the following advertising formats:

Interstitial advertisements

Full-screen advertisements may appear at eligible natural breaks after completed game sessions.

They are not intended to interrupt active card placement or ongoing gameplay.

Optional rewarded advertisements

Players who have not purchased Remove Ads may voluntarily watch rewarded advertisements to receive eligible in-game benefits, including:

• Bonus experience points after a completed run.

• A Second Chance (Undo) for an eligible card placement.

Rewarded advertisements are optional. Rewards are granted according to the application's rules and the advertising provider's confirmed reward events.

No mandatory advertisements during active gameplay

BUP 21 does not use advertising banners, app-open advertisements, or mandatory mid-gameplay advertisements under its current advertising configuration.

Information processed by Google AdMob

When advertising services are permitted and used, Google's advertising technology may automatically collect or process:

• Internet Protocol (IP) addresses, which may be used to estimate general geographic location.

• Device and advertising identifiers, where available and permitted.

• Application interaction information, such as app launches, taps, and advertisement views.

• Advertising engagement and measurement information.

• Diagnostic information, including application or SDK performance and stability data.

• Other information required for advertising delivery, security, and fraud prevention.

Depending on applicable law, user preferences, and Google's advertising systems, such information may be used for advertisement delivery, personalization, measurement, analytics, and fraud prevention.

Google processes this information in accordance with its applicable policies, terms, and privacy controls.

4. Remove Ads Purchase

BUP 21 offers an optional permanent Remove Ads purchase.

After the application has successfully verified ownership of Remove Ads:

• Interstitial advertisements are disabled.

• Rewarded advertisements are disabled.

• Rewarded advertising offers are not presented.

• Advertising requests and advertisement preloading are disabled.

Remove Ads means that BUP 21 does not request or display advertisements once the entitlement has been verified.

Google Play Billing and other services necessary for purchases and normal application operation may continue to function.

Removing advertisements does not delete information previously processed by third-party advertising services. Such information remains subject to the applicable provider's retention policies and user privacy controls.

5. Consent and Privacy Choices

BUP 21 integrates Google's User Messaging Platform (UMP) to manage advertising-related privacy choices where applicable.

Depending on your location and relevant privacy regulations, you may be presented with options relating to:

• Personalized and non-personalized advertising.

• Advertising identifiers and related technologies.

• Advertising measurement.

• Data processing for advertising purposes.

• Applicable consent or opt-out rights.

European Economic Area, United Kingdom, and Switzerland

Where required, users may be shown a consent message regarding advertising-related data processing under the General Data Protection Regulation (GDPR), applicable national privacy laws, and relevant European privacy requirements.

Advertising requests are subject to applicable consent requirements and the application's consent-management configuration.

United States privacy regulations

Users in applicable US states may receive privacy notices and options relating to the sale or sharing of personal information and targeted advertising, where required.

These choices are managed through the applicable privacy messaging system and relevant Google privacy controls.

Managing privacy choices

Where required by applicable regulations, the application provides access to its available advertising privacy-options mechanism.

Users may also manage certain advertising preferences through their Android device settings and Google account.

Privacy options and advertising availability may vary by region, device configuration, and applicable law.

6. In-App Purchases and Google Play Billing

BUP 21 offers optional in-app purchases processed through Google Play Billing.

These may include:

• Permanent premium card decks.

• Permanent premium environments.

• Theme packs and digital collections.

• Remove Ads.

• Consumable Second Chance (Undo) credit packs.

All payments are processed by Google Play.

BUP Apps does not directly receive or store complete payment card numbers, card security codes, or full payment credentials.

Google may process purchase-related information, transaction identifiers, payment information, and relevant account data according to its own policies.

Permanent purchases

Permanent digital purchases are associated with the applicable Google Play purchase entitlement.

Supported permanent purchases may be restored using Google Play's purchase-restoration mechanisms.

Consumable Undo credits

Purchased Undo credits are consumable digital items.

BUP 21 stores granted Undo balances locally as application state.

Once a consumable purchase has been processed and consumed through Google Play Billing, its corresponding credits are not directly restorable from Google Play purchase history.

Restoring a local Undo balance may depend on the continued availability of the application's stored data or eligible Android backup data.

Uninstalling the application, clearing application data, changing devices, or restoring an incomplete backup may result in the loss of locally stored consumable balances.

BUP Apps does not operate a separate account-based cloud inventory system for these credits.

7. Third-Party Services and Data Sharing

BUP 21 uses the following Google services for specific application functions:

Google AdMob
Provides advertising delivery, advertisement measurement, and associated advertising services.

Google User Messaging Platform
Supports privacy notices, applicable consent collection, and advertising privacy choices.

Google Play Billing
Processes optional digital purchases and supports purchase entitlement verification.

These services may process data under their respective terms, privacy policies, and applicable legal obligations.

BUP Apps does not independently sell locally stored gameplay records to advertisers or data brokers.

However, third-party advertising services may collect or share certain device, interaction, diagnostic, or advertising-related information as described in this policy.

Users should review Google's Privacy Policy for more information about data processing by Google services.

8. Data Retention, Backup, and Deletion

Locally stored BUP 21 information generally remains on the device while the application's data is retained.

Users may remove local application data through Android's application storage controls or by uninstalling the application.

Deleting local application data may remove:

• Saved scores and statistics.

• Local gameplay progression.

• Customization preferences.

• Daily usage records.

• Locally stored consumable Undo balances.

Certain data may remain in Android backups depending on device settings, Google account configuration, and backup retention rules.

Permanent purchases associated with Google Play may remain recoverable through Google's supported purchase mechanisms.

Information collected or processed directly by Google services is subject to Google's independent retention, security, and deletion practices.

Users can manage relevant Google account data and privacy controls through Google's available account settings.

For privacy or data-related questions concerning BUP Apps, users may contact the developer using the details provided below.

9. Children's Privacy and Age Considerations

BUP 21 is not specifically designed for or directed at children under the age of 13.

The application does not require users to provide their names, email addresses, or personal contact information to participate in gameplay.

Advertising, consent, and in-app purchase features are subject to applicable Google Play policies, regional privacy requirements, and age-related protections.

Parents and guardians are encouraged to review children's device settings, Google Play purchase controls, and applicable advertising privacy preferences.

BUP 21 does not offer real-money gambling or cash-prize functionality.

The application's official age or content rating is determined through the relevant application marketplace and content-rating processes.

10. Data Security

BUP Apps seeks to minimize unnecessary data collection and relies on Android and established Google platform services for the application's core storage, advertising, consent, and payment functions.

Gameplay information is primarily stored through Android's local application storage mechanisms.

Google's advertising services implement transport security measures for data transmitted through their supported SDKs.

Payment information is processed using Google Play's payment infrastructure rather than being collected directly by BUP Apps.

Although reasonable measures are used to protect information, no electronic storage, communication, or transmission system can be guaranteed to be completely secure.

11. International Data Processing

Google and its service providers may process information in countries other than the country where a user resides.

Such processing is governed by the applicable service provider's contractual arrangements, privacy policies, and legal requirements.

Depending on jurisdiction, users may have additional privacy rights and protections concerning international transfers of personal information.

BUP Apps does not operate an independent international gameplay-data hosting infrastructure for BUP 21.

12. Your Privacy Rights

Depending on your location and applicable law, you may have rights relating to personal information, including:

• Requesting access to certain personal information.

• Requesting correction of inaccurate information.

• Requesting deletion where legally applicable.

• Objecting to or restricting certain processing.

• Withdrawing consent where processing is based on consent.

• Exercising applicable opt-out rights relating to targeted advertising or personal-data sharing.

• Submitting a complaint to a competent data protection authority.

These rights may be subject to applicable legal conditions and exceptions.

Because BUP 21 does not operate a separate user-account system or remotely store individual gameplay histories, some local gameplay information can be managed directly through Android's application-data controls.

Information processed by Google may require users to exercise their rights through Google's own privacy controls or contact mechanisms.

For questions or requests relating to data handled by BUP Apps, please use the contact information below.

13. Website Hosting and External Links

This Privacy Policy is made available through the official BUP Apps developer website hosted on Google Sites.

When visiting this website, Google may process website-related information, such as device data, usage information, or cookies, according to Google's applicable policies.

Website-related processing is separate from the application's locally stored gameplay records.

The policy may also be linked from Google Play, Google AdMob privacy messages, or other official BUP Apps web properties.

External websites and third-party services are governed by their own applicable privacy policies.

BUP Apps may update this Privacy Policy when:

• Application functionality changes.

• Advertising or purchase systems change.
