2. Information We Collect
A. Analytics Data
The App uses Google Analytics for Firebase (Firebase Analytics) to understand how the App is used and to improve performance and usability. Depending on platform and configuration, analytics data may include:
- app and screen interaction data;
- device, browser, app version, and technical usage information;
- identifiers, cookies, or similar technologies where applicable;
- event data related to App usage, including screen views and feature interactions.
Based on the current implementation, analytics events may also include interaction parameters such as selected conversion mode, preset usage, decimal precision, configured range values, and calculation-related event parameters generated during App use.
B. Feedback Data
If you choose to submit feedback through the App, the following data may be collected and stored in Firebase Firestore:
- your message;
- your email address, if you choose to provide it;
- timestamps related to submission and updates.
Submitting feedback is voluntary. Please do not include sensitive personal data in your message.
3. Information We Do Not Intentionally Collect
The App does not require user account registration and does not intentionally collect payment information. The App also does not maintain a dedicated database of user calculation history tied to a user identity.
4. How We Use Your Information
We use collected information to:
- operate and maintain the App;
- understand usage patterns and improve the App;
- monitor performance, stability, and feature usage;
- review and respond to feedback;
- protect the App against misuse or technical issues.
5. Legal Bases for Processing
Where applicable under data protection law, the following legal bases may apply:
- legitimate interests, to operate, secure, maintain, and improve the App;
- consent, where required for analytics technologies or where you voluntarily provide optional personal data;
- legitimate interests and your request, when you contact the developer or submit feedback and expect a response.
7. International Data Transfers
Because Google and Firebase services may process data on infrastructure located in different countries, your information may be transferred to and processed outside your country of residence, including outside the European Economic Area. Where required, such transfers are made subject to applicable legal safeguards.
8. Data Retention
Analytics data is retained according to the retention settings and policies of the analytics services in use. Feedback data is kept only for as long as reasonably necessary to review, respond to, and act on the feedback, unless a longer retention period is required by law.
9. Your Rights
Depending on your location and applicable law, you may have the right to request access to your personal data, correction, deletion, restriction of processing, objection to processing, or data portability. You may also withdraw consent where processing is based on consent.
