Privacy Policy
Last updated: 23 October 2026
Who we are and scope
Kosin Games is the independent game developer Martin Sinkó, based in Hungary. Our website is kosingames.com. Contact us at sinko.developer@gmail.com.
This policy describes the handling of information in mobile games published by Kosin Games that link to this policy, including Waterpark & Shop - Simulator. It also applies to games published under the Applications-B or Malum Applications names when they link to this policy. Features and service providers vary by game and platform; a section about an optional feature applies when that feature is present.
Information processed and its purposes
- Game progress and settings: games store progress, balances, preferences and purchase-related entitlement information on your device to operate the game and remember your choices.
- Advertising: games that contain Google AdMob use the Google Mobile Ads SDK. Depending on permissions, consent, platform and configuration, Google and its advertising partners may process IP addresses (including approximate location derived from them), device or advertising identifiers, ad interactions and diagnostic information to deliver and measure ads, operate their services and prevent fraud.
- Purchases: Google Play or Apple's App Store processes in-app payments. The game receives product, transaction and purchase-status information to deliver purchased content and check or restore applicable entitlements. We do not receive your full payment-card details from these store purchases.
- Optional online and saved-game features: games offering Google Play Games may process sign-in status, player-related identifiers and saved-game data through Google. Where cloud saving is offered, using that feature sends saved-game data to the provider so it can be retrieved or managed. Availability differs by platform.
- Support: if you contact us, we receive your email address and the information you choose to send, and use it to respond and resolve your request. Do not send passwords or payment-card details.
- Technical operation: integrated services may process device information and diagnostic records to maintain functionality, investigate failures, secure their services and prevent abuse. The website's hosting provider, Cloudflare, processes request information such as IP addresses and technical connection details to deliver and protect the website.
Service providers and sharing
Information is processed by the providers used in the particular game or website feature, including Google for advertising, Google Play billing and Play Games features; Apple for App Store purchases and platform services; Unity for relevant engine or purchasing services; and Cloudflare for website hosting and delivery. Their own policies explain their processing, storage and privacy controls:
- Google Privacy Policy
- Google advertising technologies
- Apple Privacy Policy
- Unity Privacy Policy
- Cloudflare Privacy Policy
Providers may process information in countries other than your country of residence. Their policies describe applicable international-transfer safeguards. Information may also need to be disclosed when required by law or to address security, fraud or legal claims.
Privacy choices and permissions
Where applicable, the game presents a consent message for advertising. You can revisit advertising privacy choices through the game's privacy options when that option is provided or required. Device settings also provide advertising-identifier and privacy controls.
On iOS, tracking permission, when requested, is controlled through Apple's App Tracking Transparency prompt and device settings. Refusing tracking permission does not require you to give permission in order to play. Refusing personalized advertising or tracking does not necessarily stop all ads or all processing needed to deliver permitted ads.
Optional online features can be left unused. You can manage connected platform services through the settings provided by Google or Apple. Platform and service-provider records are governed by the relevant provider's retention and deletion practices.
Children's privacy
Our games have different intended audiences. Consult the individual game's store listing for its audience and content rating. Content ratings describe game content and do not by themselves describe the data processed by advertising or platform services.
Parents and guardians can use device and store parental controls to manage downloads, purchases and privacy permissions. If you believe information relating to a child has been handled improperly, contact sinko.developer@gmail.com with the game name and the relevant details so we can investigate and address the request, including deletion where applicable. Please do not send unnecessary personal information about the child.
Retention and deletion
Local progress and preferences remain on your device until removed through available game or device controls. Uninstalling a game or clearing its application data normally removes local data, although device or operating-system backups may retain or restore it. Local deletion does not automatically delete a cloud save or records held by Google, Apple or another service provider.
Where a game provides cloud-save deletion, use its cloud-save controls to request deletion of those saved games. You can also use the provider's account and data-management controls. Purchase records may be retained by the store for transaction history, restoration, fraud prevention and legal obligations.
Support correspondence is retained as needed to handle your enquiry and any applicable legal or security requirements. Contact us to request access, correction or deletion of information that we hold about you; identify the game and request without including unnecessary sensitive information. Depending on your location, additional privacy rights and the right to complain to a data-protection authority may apply. We may need proportionate information to verify a request. We cannot directly delete records controlled solely by an independent platform provider.
Security
We use reasonable safeguards appropriate to the information and services involved. Relevant platform providers apply their own security measures. No method of storage or transmission can guarantee absolute security.
Links and changes
Our games and website may link to external services, including app-store pages and the provider policies above. Review their policies when using those services. We update this policy when our practices change and show the updated date on this page.
