Effective Date: March 8, 2026

The Short Version

GR Control is designed with a privacy-first approach. We do not require user accounts and do not directly collect personal information.

To provide a high-quality experience, we use industry-standard analytics to monitor performance and stability. We also utilize a third-party service to securely manage and validate in-app purchases. All financial transactions are handled through the platform’s native billing system, and we never have access to your payment card details.

1. Introduction

This Privacy Policy explains how GR Control ("the App", "we", "our", or "us") handles information when you use our mobile application.

GR Control is published by an individual developer.

We are committed to protecting your privacy and complying with the General Data Protection Regulation (GDPR) and other applicable data protection laws.

2. Information We Do Not Directly Collect

The App:

• Does not require user registration
• Does not collect names or email addresses
• Does not directly collect or store payment card details
• Does not create user profiles

3. Analytics Data Collection

The App uses Google Analytics for Firebase, provided by Google LLC, to understand how users interact with the App for improving app performance and user experience.

Google Analytics for Firebase may automatically collect certain technical and usage information, including:

• Device type and model
• Operating system information
• App version
• App usage events (such as screen views and feature interactions)
• Approximate geographic location (country or region level)
• Device identifiers (such as Firebase Instance ID or advertising identifiers, if enabled)

This data is used strictly for:

• Improving app performance
• Understanding feature usage
• Monitoring stability and reliability
• Enhancing user experience

We do not use analytics data to identify individual users.

4. In-App Purchases and Subscription Management

The App may offer optional paid subscriptions or in-app purchases.

Payments are processed by the platform provider through which you downloaded the App. We do not collect or store payment card details.

To validate purchases and manage subscriptions, we use RevenueCat, a third-party subscription management service provider.

RevenueCat may process the following information:

• App User ID (a randomly generated identifier)
• Purchase and subscription status
• Product identifiers
• Transaction receipts
• Device information (such as platform and app version)

This information is used strictly to:

• Validate purchases
• Provide access to paid features
• Restore purchases
• Prevent fraud

5. Legal Basis for Processing (GDPR)

If you are located in the European Economic Area (EEA), United Kingdom, or similar jurisdictions, our legal basis for processing is:

• Legitimate Interests (Article 6(1)(f)) — for analytics and service improvement.
• Performance of a Contract (Article 6(1)(b)) — to provide paid features and manage subscriptions following a purchase.

Where required by law, certain processing activities may rely on user consent provided through platform-level privacy controls.

6. Data Sharing and Service Providers

We do not sell, rent, or trade personal data.

We use the following service providers who process data on our behalf:

Google LLC
1600 Amphitheatre Parkway
Mountain View, CA 94043, USA
https://policies.google.com/privacy

RevenueCat, Inc.
1032 E Brandon Blvd #3003
Brandon, FL 33511, USA
https://www.revenuecat.com/privacy

These service providers process data under their respective privacy policies and applicable data protection agreements.

7. International Data Transfers

Data may be processed on servers located outside your country, including in the United States.

Where required, appropriate safeguards such as Standard Contractual Clauses (SCCs) are relied upon for international data transfers.

8. Data Retention

Analytics data is retained according to the retention settings configured in the Firebase platform.

Subscription-related data is retained as necessary to validate purchases, comply with legal obligations, and resolve disputes.

9. Your Rights Under GDPR

If you are located in the EEA or UK, you have the right to:

• Request access to your data
• Request correction of inaccurate data
• Request deletion of data
• Object to processing
• Request restriction of processing
• Request data portability
• Withdraw consent where applicable

Because the App does not directly identify users, we may not be able to associate certain technical data with a specific individual without additional information.

10. Managing Privacy Settings

You may limit analytics tracking by:

• Disabling advertising identifiers in your device settings
• Using platform-level privacy controls available on your device

11. Children's Privacy

The App is not directed to children under the age of 13. The anonymized analytics data collected through Google Analytics for Firebase does not identify individual users, including children.

12. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Updates will be reflected by updating the Effective Date.

Continued use of the App after changes constitutes acceptance of the revised Privacy Policy.

13. Governing Language

This Privacy Policy may be translated into other languages for convenience. In the event of any discrepancy, inconsistency, or conflict between the English version and any translated version, the English version shall prevail.
