This Privacy Policy explains how Grinding Vision ("we", "our", "us") collects, uses, stores, and shares personal data when you use our mobile games, website, and related services.
This policy applies to all games and apps published by Grinding Vision on app stores unless a separate policy is provided for a specific app. For Block Flow, the details below reflect the current production integrations and data flows.
1. Information We Collect
Depending on the game and your device settings, we may collect:
- Support data: email address and messages you send to support.
- Gameplay and analytics data: events such as app opens, sessions, gameplay interactions, progression metrics, and technical event parameters (for example app version, platform, and basic device context).
- Device and technical data: device model, OS version, language, app version, identifiers, and approximate region.
- Crash and diagnostics data: crash traces, non-fatal exception logs, and diagnostic metadata used to detect and fix stability issues.
- Notification data: push notification token (Firebase Cloud Messaging token) and related message metadata needed to deliver notifications.
- Purchase-related data (if purchases are enabled): app store transaction status and receipt metadata required to process and validate purchases.
2. How We Use Information
We use collected information to:
- provide, operate, and improve our games and services;
- maintain security, prevent fraud, and fix technical issues;
- analyze performance, retention, and game balance;
- process purchases and restore player progress;
- deliver push notifications when enabled by you/device settings;
- communicate updates, support responses, and service notices;
- comply with legal and regulatory obligations.
3. Legal Basis (Where Applicable)
Where required by law, we process personal data based on legitimate interests, contract performance, legal obligations, and your consent (for example, where consent is required for personalized advertising or tracking).
4. Sharing of Information
We may share information with trusted third parties, such as:
- cloud hosting and infrastructure providers;
- analytics, crash reporting, and messaging providers (including Google Firebase services);
- payment processors and app stores;
- advertising partners (only if advertising is enabled in an app);
- legal authorities when required by law.
We do not sell personal data as an independent product to data brokers.
Block Flow currently uses Firebase Analytics, Firebase Crashlytics, and Firebase Cloud Messaging to support analytics, diagnostics, and notifications.
5. Data Retention
We keep data only for as long as needed for the purposes described in this policy, including legal, accounting, security, and dispute resolution requirements.
Retention periods vary by data type. For example, support requests may be retained for customer service history, while crash and analytics records are retained according to provider retention settings and operational needs.
6. Children's Privacy
We do not knowingly collect personal data from children in violation of applicable law. If a specific app is directed to children, we apply additional safeguards required by applicable legislation.
7. Your Rights
Depending on your location, you may have rights to access, correct, delete, or restrict processing of your personal data, and to withdraw consent where processing relies on consent.
To exercise your rights, contact us at support@grindingvision.com.
You can also manage app-level permissions (for example notifications) through your device settings.
8. Security
We use reasonable technical and organizational measures to protect personal data from unauthorized access, alteration, disclosure, or destruction.
9. International Transfers
Your information may be processed in countries other than your own. In such cases, we apply safeguards required by applicable law.
10. Changes to This Policy
We may update this Privacy Policy from time to time. Updated versions will be published on this page with a revised "Last updated" date.
11. Third-Party Services
Some processing is performed by third-party service providers acting on our behalf or as independent controllers depending on the context. You can review their privacy terms here:
