Chessis Privacy policy

Chessis Privacy Policy

This Privacy Policy describes how we collect, use, and protect information when you use our mobile application "Chessis" (the "App"). By installing and using the App, you agree to this Privacy Policy and the processing of data as described herein.

If you do not agree with this Policy, please do not use our App. Your continued use of the App following any changes to this Policy will be deemed your acceptance of those changes.

What Data We Collect and Why

When you use our App, we automatically collect certain types of data to provide core functionality and improve your experience. All data collection is required for the App to function properly, and users cannot opt out of this collection.

Device and Usage Data

• Device identifiers (Firebase installation IDs)

• App interaction data (screen views, button taps, session duration)

• App performance metrics and usage statistics

• Purpose: To enable core app functionality, understand how users interact with the app, and improve app performance

Crash and Diagnostic Data

• Crash reports and error logs

• Device information (OS version, device model, app version)

• Diagnostic data for debugging and troubleshooting

• Purpose: To identify, diagnose, and fix technical issues and app crashes

Technical Information

• App performance data (loading times, response rates)

• Non-personal device information (language settings, OS version)

• Purpose: To monitor app health and optimize performance

Data Processing and Storage

All data collected is processed by Google Firebase services (Firebase Analytics and Firebase Crashlytics) acting as our service provider. Firebase processes this data on our behalf to provide analytics and crash reporting services.

All data is encrypted in transit using Transport Layer Security (TLS) protocol to ensure secure transmission.

Data Sharing

We do not sell, trade, rent, or share your data with third parties. Firebase processes data on our behalf as a service provider, not as a third-party recipient. Any data processing by Firebase is subject to their privacy policies and security standards.

Data Retention

Data is automatically deleted according to Firebase's standard retention policies, typically within 90 days for most data types. We do not store data longer than necessary for the purposes outlined in this policy.

Legal Basis for Processing

We process data based on our legitimate interest to provide, maintain, and improve our App's functionality and user experience, as well as to ensure technical stability and security.

Data Security

We implement appropriate technical and organizational measures to protect your data against unauthorized access, alteration, disclosure, or destruction. However, no method of transmission over the internet is 100% secure.

Your Rights

Since our App does not collect personally identifiable information and uses only anonymized technical data, individual data deletion requests are not applicable. All data is automatically purged according to Firebase retention policies.

Children's Privacy

Our App does not knowingly collect personal information from children under 13. If we become aware that we have collected personal information from a child under 13, we will take steps to delete such information.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify users of any material changes by updating the "Last Updated" date at the bottom of this policy. We encourage you to review this policy periodically.
