Color Rush: Brain Challenge (“the game”) is a color-word puzzle game for Android, published by Virtual Zento LLC under the Greatcomforter brand.
The game does not need an account. We do not ask for your name, email address, phone number, contacts, photos or precise location.
Your progress is stored on your device. It is not sent to us.
The game is free and shows ads through Google AdMob. Google’s advertising software inside the game may collect and process some information from your device, as described by Google. Section 3 explains the advertising formats and what Google’s software collects. Sections 5, 6 and 7 explain your choices.
The game saves the following on your device only, in Android’s private app storage:
your level progress, stars, scores and coins;
achievements and in-game backgrounds you bought with in-game coins, never with real money;
settings such as sound, music, vibration, speed and accessibility options;
simple counters the game uses to apply its own limits, such as how many optional reward videos you watched today, when an ad was last shown between levels, and when the game last offered the Google Play review card.
We (Virtual Zento LLC) do not receive this information. If Android backup is enabled on your device, Android may include your Color Rush saved progress, coins, achievements, settings, and game counters in a backup associated with your Google account. This backup is managed by Android and Google under your device and account settings. Virtual Zento LLC does not receive your saved game data through this process.
Uninstalling Color Rush removes its locally stored data from your device, but an existing backup copy may remain subject to Google’s backup retention and deletion policies.
The game is free to play and contains two advertising formats, delivered by Google AdMob, the Google Mobile Ads SDK, from Google LLC:
Rewarded advertisements. Optional videos that you choose to watch. Successfully completing a rewarded video grants 50 in-game coins. You may decline to watch a rewarded video at any time; the reward is issued only after successful completion is confirmed.
Interstitial advertisements. Occasional full-screen ads shown at natural transitions between completed levels. They are never shown during active gameplay questions. Unlike rewarded videos, these ads are not individually optional.
Which advertisements appear may depend on network connectivity, regional privacy requirements, the consent choices you make, and Google’s advertising services.
According to Google’s current documentation (checked October 2026), the Google Mobile Ads SDK and associated Google SDKs may process the following information for advertising delivery, measurement, fraud prevention, security and related purposes:
Device identifiers: including the Android advertising ID and the app set ID where available, and other identifiers related to signed-in accounts on the device.
Approximate location: inferred from the IP address. This is a general area, not a precise location.
App and advertising interactions: for example app launches, taps, ad views and video views.
App performance and diagnostics: for example app launch time, hang rate and energy usage.
This information is processed by Google’s SDKs and is not received or managed by Virtual Zento LLC. The game does not require registration, which does not mean it involves no data collection: the advertising-related processing described here is part of an ad-supported game.
Google states that all of the user data its SDK collects is encrypted in transit using the TLS protocol. Google processes it under its own policies:
The SDK collects this data directly from the device. We do not receive it. Google states that it never sells personal information. Because legal definitions of “sale” and “sharing” under US state privacy laws are more specific than everyday language, we make no broader claim here.
You can find controls for your advertising ID in your Android device’s privacy settings or in Google advertising settings. Exact menu names vary by device and Android version. Resetting or deleting the advertising ID, where supported, can limit or change how advertising services use that identifier, but it does not necessarily stop all advertising-related data processing.
We configure the ads for general audiences, with a maximum ad content rating of PG.
Where consent or an opt-out request is required, for example in the European Economic Area, the UK, Switzerland and certain US states, the game uses Google’s User Messaging Platform (UMP) to ask for and record your advertising choices before personalized ads are requested.
How the choice is stored: on your device by Google’s software, and passed to Google’s advertising service.
You can change your choice at any time. Users in Europe, the United Kingdom and Switzerland: see section 6. Users in the United States: see section 7.
If you decline personalized ads, Google may show non-personalized or limited ads, and the game keeps working normally.
UMP is Google’s tool for showing privacy messages and recording these choices. Using it does not by itself satisfy every regional legal obligation. What the game must do depends on the laws that apply to you and to us, so we keep this policy under review rather than treating UMP as a guarantee.
Change your advertising choices: where Google’s consent rules apply, open Settings → Ads & Privacy → Privacy choices in the game. Section 6 covers users in Europe, the United Kingdom and Switzerland; section 7 covers users in the United States.
Reset or delete your advertising ID: look for advertising privacy controls in your Android device’s privacy settings or Google advertising settings. Menu names vary by device and Android version, so there is no single universal path.
Advertising and your choices: Rewarded video ads are optional. You can choose whether to watch them to earn in-game coins. The game may also display occasional interstitial ads between completed levels; unlike rewarded videos, those are not individually optional. Watching rewarded ads is not required to progress through the game.
Delete the data stored by the game: uninstall the game, or clear its storage in Android settings.
What uninstalling does and does not remove: uninstalling deletes the data listed in section 2. It does not delete information Google has already collected and processed under section 3. To limit that, reset or delete your advertising ID and use the privacy choices described above.
Your rights: depending on where you live, see section 6 (Europe, the United Kingdom and Switzerland) and section 7 (United States). Because we do not hold personal data about you, most requests about advertising data go to Google: https://policies.google.com/privacy. You can also contact us at privacy@greatcomforter.com.
Advertising Data Collection and Sharing
Color Rush uses the Google Mobile Ads SDK (AdMob) to display rewarded and interstitial advertisements. The SDK may automatically collect and share certain information with Google, including:
Approximate location derived from IP addresses.
App interactions, such as app launches, taps, and advertisement views.
Diagnostic information, including app performance metrics.
Device or other identifiers, including the Android Advertising ID and App Set ID, where available.
Google may process this information for advertising, analytics, fraud prevention, security, and compliance purposes.
Where required by applicable privacy laws, Color Rush provides consent and privacy choices through Settings → Ads & Privacy → Privacy choices.
For additional information, please review Google’s Privacy Policy and Google Mobile Ads data disclosure.
Where Google’s requirements apply, for example in the European Economic Area, the United Kingdom and Switzerland, eligible users may receive a Google consent message about advertising and related data processing when they open the game. You may accept, decline, or manage the available consent choices.
Where Google’s SDK makes privacy options available, you can revisit those choices later in the game: Settings → Ads & privacy → Privacy choices.
Depending on the law that applies to you, you may have rights such as access, correction, deletion, objection to processing, and restriction of processing, subject to applicable law. Google explains the advertising data it processes and the tools it offers at the pages linked in section 3. Because advertising data is processed by Google, we cannot directly delete information controlled independently by Google. Where we hold personal information, for example correspondence you send us, contact us using the details in section 14.
Residents of certain US states may have rights over personal information used for advertising, including the right to opt out of applicable sale or sharing of personal information or targeted advertising, subject to applicable law.
Where that option is provided, eligible users can open Color Rush → Settings → Privacy choices and select “Don’t sell or share my data”. Availability depends on applicable laws, your region, and Google’s consent-management system.
Selecting this option may reduce personalized advertising. It does not necessarily eliminate every advertisement, and it does not necessarily stop all advertising-related data processing.
We do not sell customer databases and do not maintain advertising profiles. The advertising data described in section 3 is processed by Google’s SDKs, not by us.
Google Play review card: the game may occasionally show Google Play’s own review card after you complete certain levels. It is provided and controlled by Google Play. Whether the card appears depends on limits Google sets. We do not learn whether you left a review, or whether the card was shown at all. Any review you post is handled by Google Play under your Google account.
Installation and updates: handled by Google Play under Google’s terms.
Audience: Color Rush is intended for players aged 13 and older.
What we do and don’t do: we do not knowingly collect personal information from children, and we don’t request child-directed ad treatment.
If you believe a child has used the game and data was collected, contact us at privacy@greatcomforter.com.
Data saved by the game stays on your device until you uninstall the game or clear its storage.
Advertising data collected by Google is kept according to Google’s retention policies: https://policies.google.com/technologies/retention.
Messages you send us, such as emails, are retained only as long as reasonably necessary to respond to you, maintain appropriate records, and meet applicable obligations. We have not adopted a fixed routine retention period; if we do, we will update this policy.
The game’s saved data stays in Android’s private app storage on your device. Google states that data collected by its advertising software is encrypted in transit.
Google may process advertising data in countries other than yours, under Google’s safeguards.
If we change this policy, we’ll update the effective date above and publish the new version at this address. Significant changes will also be described in the game’s update notes.
