Effective date: August 8th, 2026 Last updated: August 8th, 2026
This Privacy Policy explains how Marianne Bosch ("we," "us," "our") handles information in connection with the mobile game Mahjong Meditations Solitaire (the "Game") on iOS and Android.
We built the Game to collect as little as possible. We do not require an account, and we do not collect your name, email address, or phone number. The Game shows ads, but they are non-personalized — they are not based on a profile of you and do not use your device's advertising identifier (IDFA/AAID) to track you across apps.
a. Anonymous usage & gameplay analytics. The Game records anonymous events (for example: a level started, completed, failed, or abandoned; a booster used; a daily login) so we can understand where players enjoy the Game or get stuck and improve difficulty and balance. These events are tied only to a random identifier generated on your device at install — not to you personally. They are processed through Google Firebase / Google Analytics for Firebase and, on iOS, Apple's built-in App Analytics. The Game is configured not to collect the device advertising identifier and not to use data for advertising personalization.
b. Purchase measurements. If you make an in-app purchase, the transaction itself is handled entirely by Apple's App Store or Google Play — we never receive or store your payment card details, billing address, or identity. We may record an anonymous measurement that a purchase occurred (for example, which item and its price) to understand what players value.
c. Crash and diagnostic data. If the Game encounters an error, we may collect anonymous technical information (error type, device model, operating system version) to fix bugs.
d. Information you choose to send us. If you submit feedback or a bug report through the Game's Help screen, we receive the text you type. Please don't include sensitive personal information in that text.
e. On-device storage. Your progress, coin balance, daily-streak state, sound preference, and the random anonymous identifier are stored locally on your device (browser localStorage within the app). This data stays on your device and is removed if you delete the Game or clear its data.
We do not collect precise location, contacts, photos, microphone, or camera data.
We use the information above only to: operate and maintain the Game; understand engagement and difficulty so we can improve the Game; process and restore in-app purchases; show non-personalized ads (via Google AdMob); diagnose crashes and fix bugs; and respond to feedback. We do not sell your personal information, and we do not use it for cross-app advertising tracking.
The Game relies on the following providers, each of which processes data under its own privacy policy:
Advertising. The Game shows ads served by Google AdMob. We use non-personalized ads only — they are based on general context (such as the app you're using), not on a profile of your interests or your activity across other apps, and they do not use your device's advertising identifier (IDFA/AAID) for tracking. Google may still process limited information needed to serve and measure ads (for example coarse, non-identifying signals and ad interactions) under its own policies: https://policies.google.com/technologies/ads. Players who purchase the "No Ads" option are not shown ads (optional "rewarded" ads you choose to watch may still be offered).
Where the GDPR or UK GDPR applies, we process data on the basis of our legitimate interests (operating, securing, and improving the Game using anonymous analytics and showing non-personalized ads) and, where required, your consent. Because we use non-personalized ads and anonymous analytics — neither of which tracks you — we do not rely on consent for tracking-based advertising. Where required in the EEA/UK, Google's consent tool may present an ad-consent choice; declining keeps ads non-personalized. You may object to processing based on legitimate interests as described in Section 7.
Anonymous analytics are retained by Firebase/Apple according to their standard retention settings (configurable in the Firebase console, typically up to 14 months for event-level data) and then automatically deleted or aggregated. On-device data persists until you delete the Game or clear its data.
The Game is intended for a general audience and is not directed to children under 18. We do not knowingly collect personal information from children. Because we require no account and collect no personal identifiers, the Game does not build profiles of any user, including children. If you believe a child has provided us personal information through the feedback form, contact us at boschmonster@yahoo.com and we will delete it.
Depending on where you live (e.g. EEA/UK under GDPR, California under the CCPA/CPRA, and similar laws), you may have rights to access, correct, delete, or restrict processing of your personal information, to object to certain processing, and to not be discriminated against for exercising these rights.
Because our analytics are anonymous and not linked to your identity, we usually cannot associate that data with a specific person, and we cannot look you up by name or email. You can still:
California "Do Not Sell/Share": We do not sell or share personal information as those terms are defined under the CCPA/CPRA.
We use reasonable technical measures to protect information, and we minimize what is collected in the first place. No method of transmission or storage is 100% secure, but the Game is designed so that little to no personal data leaves your device.
Our providers (Google, Apple) may process data on servers located outside your country, including the United States. They provide safeguards for such transfers under their respective privacy frameworks.
We may update this Policy as the Game evolves (for example, if we add features). Material changes will be reflected by updating the "Last updated" date and, where appropriate, an in-Game notice. Continued use after an update means you accept the revised Policy.
