Privacy Policy

Draft update: pending publication. The effective date will be set when this update is published.

Number Merge: 2048 Puzzle is a casual number puzzle game provided by Long Studio. This policy explains what information may be processed when players use the app.

The Android app (package com.numbermerge.puzzle2048), version 1.0.3 (versionCode 4), uses Google Mobile Ads SDK 24.9.0 (AdMob) and Google User Messaging Platform (UMP) 4.0.0. iOS and earlier app versions may still use Unity Ads. The Android advertising behavior described below applies to this version, not to every platform or historical release.

Information We Collect

Local gameplay progress, including level progress, completed daily challenges, booster counts, and ad pacing counters.
Device and technical data such as device model, operating system version, app version, diagnostics, crash information, and network status.
Advertising-related data collected and shared by Google Mobile Ads, including IP address (which may be used to estimate approximate location); user product interactions such as app launches, taps, ad impressions and interactions, video views, and rewarded-ad completion events; diagnostic and performance information such as crash logs, startup time, hang rates, and energy usage; and device or other identifiers such as the Android advertising ID, App Set ID, and other advertising-related identifiers.
Optional leaderboard display information, such as player display name, avatar initials, country code, city label, completed level or daily board, moves used, moves left, and completion time.
Optional support information players provide by email, such as email address, message content, attachments or screenshots, device model, and app version, which we process to respond to the request.

How We Use Information

Provide the puzzle game, save local progress, and restore gameplay state.
Deliver and measure advertising, perform analytics, prevent fraud, maintain security, and meet compliance requirements through Google Mobile Ads in the Android version described above and Unity Ads in iOS or earlier versions that use it.
Provide global and country leaderboards. Ranking uses fewer moves first, then shorter completion time.
Improve stability, diagnose crashes, prevent abuse, and respond to support requests.
Comply with platform, legal, security, and policy requirements.

Advertising

Google Mobile Ads processes the advertising data described above. Unity Ads may process IP address, advertising identifiers, ad interactions, and diagnostic information in iOS or earlier versions that use it. Google states that data collected by its Mobile Ads SDK is encrypted in transit using Transport Layer Security (TLS). This describes a transmission safeguard, not a guarantee of absolute security or an absence of data processing.

Current Android version 1.0.3 uses the following ad formats and timing rules. These limits do not describe iOS or historical versions, and an eligible opportunity does not guarantee that an ad is available or permitted.

Banner: banner ads are displayed in the game's banner area.
Rewarded: players actively choose whether to watch. Successful completion, confirmed by the ad provider, can grant in-game items or additional moves. These rewards have no monetary value.
Interstitial: ads are eligible only at round transitions. The first 20 counted rounds are protected; after that, the first eligible round is round 30, followed by every 10 counted rounds. An ad is not deferred to interrupt active play.
App Open: an ad is attempted only on a cold start after the app has been installed for at least 72 hours, at most once per cold start. If it is not ready within four seconds, it is skipped, not displayed later after gameplay has started. App-open ads do not provide a reward.

Advertising Privacy Choices

On Android, the app requests or refreshes consent information through UMP at startup to check the requirements for the player's region. It requests ads only when UMP's canRequestAds allows it. When UMP requires a privacy-options entry, the in-game Settings screen provides Ad privacy choices, where players can review and change their choices, including withdrawing consent where applicable. Android users can also reset or delete their advertising ID through device settings.

Refusing or withdrawing consent does not necessarily end all technical data processing or make the app ad-free. Processing and ad availability remain subject to the player's choices, regional requirements, Google's configuration, and necessary security and fraud-prevention processing. Ads are not necessarily personalized. Other game and support functions may also process information as described in this policy.

This policy describes the app's data practices. Publishing it does not confirm that Google Play declarations or AdMob privacy messages have been configured or approved.

For the providers' explanations, see:

Leaderboards and Location Labels

Leaderboards may display a player's chosen name, avatar initials, country flag, and city label. Country and city information is used only for leaderboard display and filtering. When available, the app may use platform profile information first; if the player allows location-based display and platform city data is unavailable, a coarse city label may be derived from IP-based lookup. If permission is denied or unavailable, the city label is shown as Unknown. We store hashed player identifiers and hashed IP-derived audit signals instead of raw platform IDs or raw IP addresses.

Game Rewards

Number Merge is a puzzle game. Items and extra moves are for use within the game only and cannot be exchanged for money.

Data Retention

Gameplay progress is primarily stored locally on the player's device until local app data is deleted. This does not mean that all information stays on the device: advertising, leaderboards, and support involve the processing described above. Leaderboard rows are retained while they are needed to provide ranking and abuse prevention. Support emails are retained only as long as reasonably necessary to respond to the request and maintain service quality. Advertising providers handle their records under their own policies, linked above.

Children

Children's privacy is important. Applicable protections and consent requirements depend on the player's circumstances and region. If you believe a child has provided personal information, contact us so we can review the concern and take appropriate action under applicable requirements.

Player Choices

On Android, players can delete local gameplay data through the app's storage settings or by uninstalling the app. Deleting local data does not by itself delete leaderboard records, support correspondence, or records held by advertising providers. Players may contact us to request access, correction, or deletion of information they provided in support requests, subject to applicable legal and security requirements. Players can also contact us about leaderboard records or other privacy questions; please describe the relevant record so we can review the request.
