1. Introduction

Welcome to Gem Sort: Crystal Puzzle 3D ("we," "our," or "us"), developed by NosferGames. This Privacy Policy explains how we handle information when you use our mobile game ("App").

By using the App, you consent to the practices described in this policy.

2. Information We Collect

2.1 Personal Data

We do not collect any personal data. The App does not require registration, login, or any personal information to use. There is no account system.

2.2 Game Data (Local Only)

Your game progress (level completion, settings, preferences) is stored locally on your device only. We do not have access to this data and it is not transmitted to any server.

2.3 Automatically Collected Data (Third-Party SDKs)

The App uses third-party services that may collect certain data automatically:

Service	Purpose	Data Collected
Google AdMob	Serving advertisements	Advertising ID, device info, ad interaction data
Firebase Analytics	Anonymous usage analytics	App events (level played, session duration), device type, OS version

This data is collected by Google and is subject to Google's Privacy Policy.

3. Advertising

The App displays ads through Google AdMob. AdMob may use your Advertising ID to serve personalized ads based on your interests.

You can opt out of personalized ads:

When you first open the App, a consent dialog will appear (for users in the EU/EEA/UK)
On Android: Settings > Google > Ads > Opt out of Ads Personalization
You can reset your Advertising ID at any time in your device settings

4. Analytics

We use Firebase Analytics to understand how players interact with the game (e.g., which levels are played most, average session length). This data is:

Anonymous: Not linked to any personal identity
Aggregated: We only view trends, not individual user data
Used to improve the game: Level difficulty balancing, feature prioritization

5. Children's Privacy

The App is rated for ages 13+ due to advertising. We do not knowingly collect personal information from children under 13. The App does not include any features that target children specifically.

6. Data Sharing

We do not sell, trade, or transfer your data to third parties. The only data sharing occurs through the third-party SDKs listed in Section 2.3, which operate under their own privacy policies.

7. Data Retention

Since we do not collect personal data, there is no personal data to retain. Third-party SDK data retention is governed by Google's policies. Local game data remains on your device until you uninstall the App or clear its data.

8. Your Rights

Depending on your jurisdiction, you may have the right to:

Access: Request information about data collected by third-party SDKs
Deletion: Uninstall the App to remove all local data. Reset your Advertising ID to dissociate from ad profiles
Opt-out: Decline personalized ads via the consent dialog or device settings
Portability: Not applicable (no personal data stored on our servers)

9. Data Security

All game data is stored locally on your device and protected by your device's security. Network communications with third-party SDKs use industry-standard encryption (HTTPS/TLS).

10. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Continued use of the App after changes constitutes acceptance of the revised policy.
