Privacy Policy for Mahjong Sense

Last updated: August 19, 2026

1. Introduction & About the Game

Welcome to the Privacy Policy for Mahjong Sense, developed and published by Naviwebs ("the Developer", "we", "us", or "our").

Mahjong Sense is a sensory and relaxing solitaire tile-matching puzzle game designed for multiple platforms, including Android smartphones and tablets, smartwatches powered by Wear OS, and web browsers. Players clear boards by finding and pairing open, identical tiles across an array of customizable boards, visual themes, environments, haptic feedback, and helpful assistive mechanics (such as hints, shuffles, undos, and wildcards).

We are dedicated to respecting and safeguarding the privacy of our players. This Privacy Policy outlines how our application operates with respect to your information, user rights, digital purchases, and integrated advertising.

2. Information Collection and Storage

Our Core Privacy Commitment: Mahjong Sense does NOT collect, store, transmit, process, or sell any Personally Identifiable Information (PII) such as your real name, email address, physical location, phone number, or contacts.

📱 Local Device Storage

All gameplay progress, completed matches, statistics, selected tile designs, audio settings, and customization preferences are saved strictly locally on your device storage (or browser LocalStorage). This data is never sent to our servers.

⚙️ Diagnostic & Store Data

Anonymous technical metrics (such as crash telemetry, device model, and OS version) may be automatically gathered by official app store platforms (e.g., Google Play Console) to ensure game stability.

3. Digital In-App Purchases (IAP)

Mahjong Sense may offer optional in-app digital purchases, such as:

Ad-Free Upgrade: A permanent option to disable third-party integrated advertisements for an uninterrupted experience.
Virtual Items & Boosters: Consumable or unlockable game helps (such as extra shuffles, reveal hints, undo tokens, and wildcard power-ups).
Cosmetic Customization: Exclusive premium tile sets, backgrounds, and visual themes.

Payment Processing Security: All digital transactions and financial operations are processed directly through the secure billing infrastructure provided by the application store (e.g., Google Play In-App Billing). Naviwebs does not have access to, collect, or retain your financial information, credit card credentials, or bank details at any time.

4. Integrated Advertising & Monetization

To support ongoing development and offer free gameplay features, Mahjong Sense may integrate third-party advertising services (such as Google AdMob or equivalent authorized ad networks).

Ad Formats: The game may display banner ads, full-screen interstitials between game sessions, or optional Rewarded Video Ads (where players can voluntarily watch a short video to earn in-game perks like extra hints, undos, or wildcards).
Advertising Identifiers: Third-party ad partners may collect and use pseudonymous device identifiers (such as the Google Advertising ID / GAID or IDFA) and non-personal diagnostic data in accordance with their privacy policies to deliver relevant ads, prevent ad fraud, and cap ad frequency.
Ad Personalization Controls: You can manage or reset your advertising identifier and opt out of personalized interest-based advertising directly within your device's operating system privacy settings.
Ad Removal: Purchasing the optional "Remove Ads" in-app purchase will disable ad network requests within the game.

5. Application Permissions

Mahjong Sense requires only essential permissions necessary to operate its core features:

Internet & Network State Access: Required to process in-app purchases through store APIs and load advertisements.
Google Play Billing Service: Required to facilitate secure digital purchases.
Haptic Feedback / Vibration: Utilized on compatible Android and Wear OS devices to provide tactile feedback during tile interactions and matches (can be toggled in settings).

The game does NOT request or require access to your camera, microphone, GPS location, contacts, photos, or file system.

6. Third-Party Services & Links

The application interacts with third-party service providers that have their own independent privacy policies:

Google Play Services: https://policies.google.com/privacy
Google AdMob: https://policies.google.com/technologies/ads

7. Legal Compliance & User Rights (GDPR / CCPA)

Depending on your jurisdiction (such as the European Economic Area under GDPR or California under the CCPA/CPRA), you have rights regarding your data:

Right of Access & Deletion: Because all game data is stored locally on your device, you can delete all your stored data, scores, and preferences at any time by simply clearing the app storage/cache from your device settings or uninstalling the app.
Right to Opt-Out of Sale/Sharing: We do not sell or share your personal data.

8. Children's Privacy (COPPA Compliance)

Mahjong Sense is suitable for a general audience of all ages. We do not knowingly collect or solicit personal information from children under the age of 13 (or under 16 in certain jurisdictions). Any in-app purchases should only be performed by an adult or with verified parental/guardian permission.

9. Changes to this Privacy Policy

We may update this Privacy Policy periodically to reflect changes in game features, legal requirements, or monetization practices. Any modifications will be published directly on this page with an updated revision date. We encourage you to review this policy periodically.
