Privacy Policy

1. Overview

Stone Zen is a stone-sorting puzzle game. You can play without creating an account, and the game does not ask you to submit a name, profile, contacts, or user-generated content.

2. Information Stored on Your Device

The game stores information locally on your device so it can preserve your progress and preferences, including:

• Your current level and tutorial progress
• Energy, undo, and additional-platform balances and recharge timing
• Sound, music, and vibration settings
• Technical privacy-request state used to retry an Analytics opt-out or deletion request

This local data is not an account and is generally removed when you delete the app, subject to your device and Apple backup settings.

3. Gameplay Analytics

We use Unity Gaming Services Analytics to understand how the game performs and how its levels and features are used. Analytics may process technical information and game events such as:

• App, device, operating-system, session, and installation information
• Level number, attempt count, move count, and time spent on an attempt
• Level completion, restart, and out-of-moves outcomes
• Use of undo or additional-platform features
• Changes to sound, music, or vibration settings
• Whether a rewarded ad was started, completed, or unavailable, and the reward category

Our custom gameplay events do not include your name, email address, free-form text, contacts, or payment information. Unity may generate identifiers and collect other technical data as described in its Game Player and App User Privacy Policy.

4. Rewarded Advertising

Stone Zen offers optional rewarded ads through Unity LevelPlay and participating ad networks, including Unity Ads. You choose whether to watch a rewarded ad in exchange for an in-game benefit.

Advertising providers may process information such as:

• Device and advertising identifiers, where available
• IP address, approximate location derived from it, language, and device characteristics
• App and ad interaction data, including impressions, clicks, completion, and reward events
• Consent, privacy, and advertising-preference signals
• Information used for ad delivery, measurement, fraud prevention, and frequency control

The ads shown and the providers involved can vary. Their processing is governed by their own policies. See Unity's privacy policy for game players and app users for more information.

5. Diagnostics and App Store Information

Apple may provide us with crash reports, performance diagnostics, download statistics, and similar App Store information when you have enabled the relevant sharing options on your device. Apple handles that information under its Privacy Policy.

6. Support Communications

If you contact us, we receive the information you choose to provide, such as your email address, message, screenshots, device model, operating-system version, and app version. Please do not send sensitive personal information.

7. How We Use Information

• Operate, maintain, and improve Stone Zen
• Understand level difficulty, feature use, and technical performance
• Deliver optional rewarded ads and grant the associated in-game reward
• Detect errors, abuse, and advertising fraud
• Respond to support and privacy requests
• Comply with legal obligations and protect our rights

8. How Information Is Shared

We may share or permit processing of information only as reasonably necessary with:

• Unity and advertising partners that provide Analytics, LevelPlay mediation, and rewarded ads
• Apple for App Store distribution, platform services, and diagnostics
• Service providers that help us operate and support the game
• Authorities or other parties when required by law or necessary to protect rights, safety, and security

We do not sell information that directly identifies you, such as your name or email address.

9. Data Retention

• Local game data remains on your device until it is overwritten, cleared, or the app is deleted, subject to device backups
• Unity currently states that raw Analytics event data is retained for 13 months, while some metrics and user-profile data may remain until deletion is requested
• Advertising providers retain information according to their own policies
• Support communications are retained only as long as reasonably necessary to resolve requests, keep appropriate records, and meet legal obligations

10. Your Choices and Rights

• You may decline to watch rewarded ads; doing so does not prevent ordinary gameplay
• You can manage tracking and personalized-ad choices in your Apple device settings where those controls are available
• You can remove locally stored game data by deleting the app, subject to device backups
• You may contact us to ask about access, correction, deletion, restriction, objection, or other privacy rights available in your jurisdiction

To make a privacy request, email [email protected]. We may need information from you to locate the relevant records and verify the request.

11. Legal Bases for Processing

Where applicable law requires a legal basis, processing may be based on providing the game and requested support, our legitimate interests in operating and improving the game, compliance with legal obligations, or your consent where consent is required. You may withdraw consent through the available device, ad, or privacy controls, without affecting earlier lawful processing.

12. Children's Privacy

Stone Zen is intended for a general audience and is not directed to children under 13. We do not knowingly ask children to provide personal information. If you believe a child has provided personal information through a support request, contact us so we can review and delete it where appropriate.

13. International Processing

Unity, Apple, advertising partners, and other service providers may process information in countries other than your own. Where required, they or we use appropriate safeguards for international transfers.

14. Security and Changes

We take reasonable steps to protect information, but no system is completely secure. We may update this Privacy Policy as Stone Zen or applicable requirements change. The latest version will be posted here with a revised effective date.
