Witch Cauldron Defense Privacy Policy

Effective date: August 4, 2026

This Privacy Policy explains how brainer handles information in Witch Cauldron Defense (마녀냄비 디펜스), package name com.brainer.defence2 (the “App”).

Summary

The App has no developer-operated server, account system, login, social feature, or payment SDK. Game progress, active-run checkpoints, and local Play Statistics are stored on your device and are not automatically sent to brainer.

The App includes Google Mobile Ads Next-Gen SDK and Google User Messaging Platform (UMP) SDK for an optional rewarded advertisement on the results screen. These Google SDKs use Internet access and may process the advertising data described below. brainer may receive aggregated advertising reports through AdMob but does not operate a server that receives your raw game progress or local Play Statistics.

Optional rewarded advertising

An advertisement is never opened automatically during a battle, at app launch, or after a result. On the results screen, you may choose to watch one rewarded advertisement for an additional stardust reward equal to 50% of that run's base reward. You can ignore the offer and continue playing every game mode and feature. Ad loading, consent, network, no-fill, dismissal, or display errors do not block saving, returning home, or starting another run.

According to Google's Mobile Ads SDK data disclosure, the SDK may automatically collect and share these data types for advertising, analytics, and fraud prevention:

• IP address, which may be used to estimate approximate location.
• User product interactions, including app launches, taps, and video views.
• Diagnostic information about App and SDK performance.
• Device and account identifiers, including the Android advertising ID, app set ID, and other applicable identifiers.

The App also allows the SDK to use Android Privacy Sandbox advertising services, including Topics, advertising ID, and attribution APIs when available. Google states that data handled by the Mobile Ads SDK is encrypted in transit using TLS. The App disables the SDK's optional crash handler, does not add Firebase Analytics or Crashlytics, and does not use AdMob mediation or third-party ad-network adapters in this release.

Google controls its processing, retention, and deletion of advertising data under its own terms and policies. See the Google Privacy Policy, Google advertising technologies, and your device's advertising and privacy controls.

Consent and privacy choices

The App requests updated consent information through Google UMP at each app launch before initializing or requesting ads. Where required, such as in the European Economic Area, United Kingdom, or Switzerland, UMP presents the applicable privacy message. Ads are requested only when UMP reports that the App may request ads.

When Google requires a privacy-options entry point, Settings > Ad Privacy Choices lets you reopen the UMP privacy form. Availability and wording of Google's form depend on your region, prior choices, and the messages configured by brainer in AdMob.

Information stored on your device

The App stores the following information in its private app storage so that its features work:

• Game progress, including stardust, research levels, standard and Abyss Night records, discovered recipes, daily progress, streaks, Moon Journal reward claims, and settings.
• A checkpoint for an active run, including battle state, ingredients, enemies, familiars, and random-number state, so that you can resume after the App closes.
• Up to 50 recent Play Statistics records, including mode, result, relative play-day information, elapsed time, act reached, defeated monsters, brews, discoveries, remaining cauldron health, tutorial state, process restoration, background count, player-action counts, time to first brew, and peak enemy and familiar counts.
• Random run identifiers used locally to prevent duplicate base rewards and rewarded-ad bonuses. The App stores only whether the most recent applicable run received each reward; these identifiers are not included in shared Play Statistics.

Local Play Statistics do not contain your name, email address, account identifier, advertising identifier, Android identifier, IP address, device model, operating-system version, location, contacts, or media. A local calendar-day number is used only to count distinct play days. Shared summaries replace it with a relative day offset and do not include an exact calendar date.

User-directed sharing

If you choose Share Anonymous Statistics on the Play Statistics screen, the App creates a plain-text summary and opens the Android system share sheet. Nothing is sent until you select a destination. The app or service you select may process the shared text under its own privacy policy. This sharing flow is separate from Google's advertising SDK processing.

Android backup and device transfer

Android may back up or transfer ordinary game progress for users who enable those operating-system features. Google or the device provider controls that processing under its own terms and privacy policy. Active-run checkpoints and Play Statistics records are explicitly excluded from Android cloud backup and device-to-device transfer.

Retention and deletion

• Ordinary game progress remains until you use the in-app progress reset, clear the App's storage, or uninstall the App. A restored Android backup may recreate eligible progress; Android backup copies can be managed through your device or Google account controls.
• An active-run checkpoint is removed when the run ends, is abandoned, progress is reset, app storage is cleared, or the App is uninstalled.
• Play Statistics keep only the 50 most recent runs. You can delete them separately from the Play Statistics screen. They are also removed when app storage is cleared or the App is uninstalled.
• Clearing app storage or uninstalling removes the App's local reward-deduplication and UMP state. Advertising information already processed by Google is governed by Google's controls and retention practices, not the App's local reset.

Because brainer has no account database or gameplay server, brainer has no server-side game-progress copy to retrieve or delete.

Security

The App uses Android private app storage for local information, blocks cleartext network traffic, and relies on HTTPS/TLS for Google SDK communications. No storage or transmission method is perfectly secure, but the App minimizes locally stored information and does not operate a gameplay-data server.

Children's privacy

The App is not directed to children under 13 and does not knowingly collect personal information from children. The intended audience is age 13 and older. If the target audience changes to include children under applicable law, advertising will not be enabled until the App and ad configuration meet the relevant Google Play Families, child-directed treatment, and consent requirements.

Changes to this policy

This policy may be updated when the App's features, SDK behavior, or legal requirements change. The effective date above will be revised, and the public policy page will contain the current version.
