Privacy contact: swifthorsetech@gmail.com.

This policy explains information handled by the Android game and when you contact us about it. The game is an ordinary dot-connection puzzle with advertising and Google Play Games leaderboard features. You do not need a separate Casual Brain account to play. This policy does not cover our other games or versions distributed through other stores.

1. Information used by the game

Progress and preferences on your device

The game saves completed and unlocked levels, hint balances and preferences such as sound settings in its local app storage. These records let you resume playing. Leaderboard scores are handled separately as explained below; a leaderboard is not a backup of all your local progress.

Advertising and consent choices

The game uses Google AdMob to show ads, including rewarded ads that can provide in-game benefits. Google’s advertising services collect device or other identifiers, such as an Android advertising ID when available, IP address, approximate location inferred from IP, app and ad interactions, and diagnostic or performance information. They use this information to deliver and measure ads, operate and improve advertising services, and detect fraud or abuse. Ad personalization depends on your consent, settings and applicable requirements.

The app integrates Google’s User Messaging Platform to request and record advertising privacy choices where a consent message is required. Advertising providers may still process information needed to deliver contextual ads, measure delivery and prevent fraud when personalized ads are not used. Read Google’s Privacy Policy and how Google uses information from apps that use its services.

Google Play Games and leaderboards

The game uses Google Play Games for sign-in and leaderboards. It can attempt sign-in when you finish a level or open a leaderboard; sign-in may happen automatically according to your Google Play Games settings. After successful sign-in, the game can access your player identifier and player name and send your completed-level score to Google Play Games.

Google processes this information to identify your game profile and provide rankings. Your player profile and scores may be visible to other players according to the service’s visibility settings. You can manage sign-in and visibility in your Google Play Games profile settings. Playing the basic puzzle does not require creating an account with us.

Game engine

The game is built with Unity. Information about Unity’s handling of data associated with its game technology and services, and its privacy request options, is available in Unity’s Game Player and App User Privacy Policy. Advertising in this game is provided through AdMob.

Messages you send us

If you email us, we receive your email address, the contents of your message and any attachments or diagnostic details you choose to send. We use them to answer questions, investigate problems and handle privacy requests. Please avoid sending passwords, payment details or unrelated personal information.

2. Sharing and service providers

Information is processed by the services described above for advertising, game features and technical operation. Our email provider processes support correspondence. Google and Unity explain their own processing and privacy controls in the policies linked above. A player name and leaderboard score may also be shared with other players through Google Play Games.

We may disclose information where necessary to comply with a legal obligation or a valid legal request, or to investigate abuse and protect users and our services. We do not publish your support messages or use them as advertising contact lists.

3. Retention and deletion

Local game data: Progress and preferences remain in the app’s storage until you clear that storage or remove the app. Clearing storage can permanently remove your local progress and hints. Android backup or restore features, if enabled on your device, are controlled by your device and Google settings.

Google Play Games data: Google retains profile and leaderboard data according to its policies and your settings. You can delete data for this game or delete your Play Games profile. This is separate from clearing local app storage, deleting other Google account activity or deleting correspondence held by us.

Advertising and other provider data: Providers retain information under their own policies for purposes such as ad delivery, measurement, security and legal requirements. Their controls and privacy contacts are available through the links in this policy. Uninstalling the game does not automatically erase information already held by a provider.

Support and privacy requests: We keep correspondence while it is needed to resolve your request, follow up on the issue, maintain necessary records or meet legal obligations. We delete information when those purposes no longer require it. You may request deletion by contacting us; any necessary retention will be explained in our response.

4. Your choices and privacy requests

Depending on your location, you may also have rights to object to or restrict processing, receive a portable copy of information, or complain to your local data protection authority. We will respond as required by applicable law. Include the app name and the nature of your request; we may need enough information to verify it. Where information is held directly by Google or Unity, their own privacy controls may be needed, and we can help identify the relevant service. Withdrawing consent does not affect processing that was lawful before withdrawal.

5. Children and age range

The game is intended for people aged 13 and older and is not directed to children under 13. We do not knowingly seek personal information from children under 13. If you believe a child has provided personal information to us, contact us so we can investigate and take appropriate steps, including deletion where required. Additional protections or parental consent requirements may apply to teenagers under local law.

6. Security and international processing

We take reasonable measures to protect information we handle and limit its use to the purposes described here. Google’s mobile advertising SDK uses encrypted connections to transmit data. No method of storage or transmission is completely secure.

Google, Unity and our email provider operate internationally. Information handled by these services may be processed outside your country. Their privacy policies describe the safeguards and legal arrangements they use for international processing.

7. Changes and contact

We may update this policy when the game, its services or applicable requirements change. We will post the updated policy at this address and change the date above. Where required, we will provide additional notice or request consent.
