Privacy Policy

This Privacy Policy applies to the Mahjong 2-Players & Solitaire mobile game published by Proteams Information Technologies Limited (“we,” “us,” or “our”). It explains what information is processed when you use the game, why it is used, and the choices available to you. Proteams Information Technologies Limited is the data controller responsible for the personal information described in this policy.

Information we process

Depending on the features you use, we may process:

• Account information: a pseudonymous Firebase user identifier created through anonymous authentication.
• Local game data: level progress, Daily Puzzle history, collected badges, virtual-coin balance, hint usage, language, sound, vibration, and privacy settings stored on your device.
• Cloud wallet information: your pseudonymous Firebase user identifier, virtual-coin balance and wallet version, fixed gameplay reward and Hint spending records, related level or puzzle references, timestamps, and security data needed to prevent duplicate operations and abuse.
• Multiplayer information: when you use multiplayer, your Firebase authentication token, a generic player label, room code, match state, scores, turn timing, tile actions, and connection information needed to create and operate the match.
• Advertising and consent data: consent choices and, where permitted, device and advertising identifiers, IP address, approximate location, device information, ad interactions, and diagnostic information used to provide rewarded and interstitial advertisements and prevent fraud.
• Optional product analytics: pseudonymous installation and session identifiers, app version, device platform, selected language, gameplay mode, progression, session and level events, hint use, virtual-currency changes, Daily Puzzle and badge events, navigation events, and advertising outcomes. We do not include your name, email address, contacts, precise location, advertising ID, device ID, free-form text, or tile and tap coordinates in analytics.
• Daily reminders: once you have earned a Daily Puzzle badge, the game schedules a limited series of daily reminder notifications on your device. They are created and delivered locally by your device, contain no personal information, and a day’s reminder is skipped once you have finished that day’s puzzle. You can turn them off at any time in your device’s notification settings for the game.
• Support communications: if you contact us, we process the contact details, message content, correspondence, identifiers, screenshots, or other attachments that you choose to provide. Please do not send passwords, payment-card details, or verification codes.
• Technical information: device and operating-system information, network status, timestamps, app diagnostics, and security signals needed to operate, secure, and troubleshoot the game and its connected services, including app attestation signals (Play Integrity on Android, App Attest on iOS) that confirm requests come from a genuine copy of the game.

How we use information

We use this information to:

• provide the game, save local progress, and support player authentication;
• synchronise virtual-coin balances and process gameplay rewards and Hint spending;
• create, operate, secure, and troubleshoot multiplayer matches;
• provide rewarded ads and interstitial ads at selected natural game breaks;
• measure game performance, balance progression, improve features, and fix problems;
• respond to support and privacy requests;
• protect players and the game from abuse, fraud, and security threats;
• comply with legal, consumer-protection, and platform obligations.

Required and optional information

The local game information needed to save your progress and the technical information needed to operate and secure Mahjong 2-Players & Solitaire are required for the corresponding features. Connected identity information is required only when authentication services are in use. Information submitted in a support request is optional, but without enough information we may be unable to respond. Multiplayer, product analytics, and rewarded-ad actions are optional and can be controlled as described below.

Virtual coins

Mahjong 2-Players & Solitaire does not sell virtual coins or offer in-app purchases. Coins may be granted under the game’s fixed reward rules and spent only on supported in-game actions, such as Hints. Virtual coins have no cash value, cannot be transferred to another player, and cannot be exchanged for money or real-world goods.

Advertising and consent

Mahjong 2-Players & Solitaire uses Google AdMob for rewarded ads and interstitial ads. The game does not show banner ads. A rewarded ad is shown only after you choose an ad-supported action, such as obtaining a Hint without enough virtual coins or entering an ad-supported Daily Puzzle. An interstitial ad may appear at selected natural breaks after a Classic level is completed. If an interstitial ad is not already ready, the game continues without waiting for it.

In the European Economic Area, United Kingdom, and Switzerland, Google’s User Messaging Platform presents the choices required for advertising and related device storage. The game checks the current consent status before requesting ads. Where a privacy options entry point is required, you can review or withdraw eligible choices from Privacy in the game’s Settings. Withdrawing consent does not affect processing already carried out lawfully. If the required consent status does not permit an ad request, an ad-supported action may be unavailable.

On iOS, Apple’s App Tracking Transparency prompt asks whether the game may track you across apps and websites owned by other companies. Only if you allow it may Google AdMob use your device’s advertising identifier (IDFA) for personalised advertising and measurement; if you decline, the IDFA is not available to the game or AdMob and ads may be less relevant. You can change this at any time in iOS Settings → Privacy & Security → Tracking.

Analytics

With your choice, we use privacy-limited product analytics to understand aggregate play, progression, and feature performance. Mahjong 2-Players & Solitaire sends these events directly to Amplitude without embedding Amplitude’s mobile SDK. Analytics is disabled until you make an affirmative choice and can be turned off later using the Analytics control in the game’s Settings. Turning analytics off clears queued analytics events and asks Amplitude to delete the analytics history recorded under the game’s analytics identifier; the game keeps that identifier on the device only until the deletion is confirmed. If Analytics is on when you delete your account in the game, the game also asks Amplitude to delete the analytics history recorded under its analytics identifier.

Service providers and disclosures

We use service providers that process information for the purposes described above:

• Google Firebase for anonymous authentication, cloud wallet operations, account deletion, Remote Config, and app security (App Check);
• Google Play on Android for app distribution, Play Integrity checks, and the in-app review prompt;
• Apple on iOS for App Store distribution, App Attest checks, the in-app review prompt, App Tracking Transparency, and local notifications;
• Google AdMob and User Messaging Platform for rewarded and interstitial ads, advertising consent, measurement, and fraud prevention;
• Amplitude for optional product analytics.

These providers process information under their own terms and privacy notices: Google Privacy Policy, Firebase Privacy and Security, Apple Privacy Policy, and Amplitude Privacy Policy.

We do not sell personal information for money. We may disclose information when required by law, to protect rights and safety, in connection with a corporate transaction, or to service providers acting for the purposes described in this policy.

Legal bases

Where UK or EEA data-protection law applies, we rely on performance of a contract to provide requested gameplay and connected features; consent for personalised advertising, advertising-related storage, and product analytics where required; legitimate interests in operating, securing, measuring, and improving the game where those interests are not overridden by your rights; and legal obligations for records and compliance.

Storage, retention, and international transfers

Game progress, badges, virtual coins, and presentation settings are stored locally on your device and may also be associated with your pseudonymous game account where needed for cloud wallet operation. Local information may be removed if you clear the app’s data or uninstall the game. On iOS, the anonymous game account is kept in the device Keychain and can remain after the game is uninstalled; deleting the account in the game removes it. Authentication, cloud-wallet, multiplayer, advertising-consent, security, and analytics information may be stored remotely by the providers described above. We retain information only for as long as reasonably needed for the purposes described in this policy, to meet legal obligations, resolve disputes, or protect the game. Provider-controlled information is retained under the applicable provider settings and policies.

Our providers may process information outside the United Kingdom or your country. Where required, international transfers use recognised safeguards such as adequacy decisions or approved contractual protections. You can contact us to request more information about safeguards applicable to a particular transfer.

Your choices and rights

Depending on where you live, you may have rights to access, correct, delete, restrict, object to, or obtain a portable copy of personal information and to withdraw consent. You can change eligible advertising choices through the Privacy option when it is available in the game, disable analytics collection through Settings, clear local app data, or uninstall the game. Withdrawing consent does not affect processing already carried out lawfully.

You can delete your game account and its associated data at any time in the game under Settings → Privacy → Delete Account. If you can no longer open the game, see our account deletion page. For other privacy requests, contact us at contact@proteams.co.uk. We may request information needed to verify and complete your request. We respond within the period required by applicable law; this is generally one month for requests under UK or EEA data-protection law, although the law may permit an extension for a complex request. UK users may complain to the Information Commissioner’s Office; EEA users may contact their local data-protection authority.

United States privacy choices

We do not sell personal information for money. Some United States privacy laws may define disclosures to advertising providers for personalised advertising as a “sale,” “sharing,” or targeted advertising even when no money is exchanged. Where such a right applies and a privacy options control is available, you can use it to manage eligible advertising choices or contact us. We will not discriminate against you for exercising an applicable privacy right. Depending on your state, you may also have rights to access, correct, delete, obtain a copy of your personal information, or appeal a decision on a privacy request.

Children

Mahjong 2-Players & Solitaire is not directed to children under 13. We do not knowingly collect personal information from children under 13. If local law requires parental consent at a higher age, a child should use the game only with permission from a parent or guardian. If you believe a child provided personal information contrary to this policy, contact us so we can investigate and take appropriate action.

Security

We use reasonable technical and organisational safeguards intended to protect information. No electronic transmission or storage method is completely secure.

Changes to this policy

We may update this policy when the game, service providers, or legal requirements change. The latest version will remain available at this URL, with its revision date shown above. Material changes may also be communicated in the game or store listing.
