Cardiac Rehab (“we”, “our”, “the app”) is committed to protecting user privacy and handling user and patient-related data responsibly.
This Privacy Policy explains how information is collected, used, stored, and protected when using the Cardiac Rehab application on Android and Desktop platforms.
We may collect:
Email address (for authentication)
User profile information (name, specialty, clinic/center information)
Optional contact details (phone number, city, country, license information)
This information is used strictly for account identification and profile management.
The application allows users to input:
Patient identification data (name, age, weight, height)
Clinical assessment results
Cardiac pathology
Exercise testing data
Program prescriptions
Follow-up sessions
This data remains stored locally on the device unless explicitly exported by the user.
We may collect:
Authentication metadata
Device identifiers required for Firebase authentication
Crash diagnostics
Performance logs
We do not collect or store unnecessary personal information.
Your information is used to:
Authenticate users securely
Synchronize user profile information across devices
Generate individualized cardiac rehabilitation programs
Produce PDF clinical reports
Maintain versioned program history
Improve app reliability and performance
Patient clinical data is stored locally:
Android: Room SQLite database
Desktop: Local JSON storage
Patient data is not automatically uploaded to cloud servers.
User profile data may be synchronized with Firebase Firestore to enable multi-device consistency.
Protected fields such as account role and verification status are preserved during synchronization.
We apply reasonable technical measures to protect data:
Sensitive logs are minimized
Authentication tokens are not logged
Raw patient data is not transmitted without explicit export
However, no method of storage or transmission is 100% secure.
We do not sell, rent, or monetize personal or patient data.
Data may only be shared:
Through manual exports initiated by the user (PDF, JSON)
Through Firebase services strictly for authentication and profile synchronization
Firebase and Google process only the data necessary for their services.
User account data remains active while the account exists.
Patient clinical data remains stored locally until deleted by the user.
Program history may retain superseded versions for clinical traceability.
Exported files remain under the responsibility of the user who generated and shared them.
Users can:
Edit their profile
Delete patient files
Delete individual program versions
Export local data
Users may request account deletion by contacting:
km.mail.contact@gmail.com
Deletion requests will be processed within a reasonable timeframe.
Cardiac Rehab is not intended for direct use by children or minors.
The application does not knowingly collect personal information directly from children.
The application may be used by healthcare professionals, students, or other users interested in generating cardiac rehabilitation programs.
However, all generated rehabilitation plans are provided for informational and assistance purposes only and must be reviewed, validated, and approved by a qualified physician or licensed healthcare professional before being applied to a real patient.
If future pediatric clinical support is introduced, additional child-specific protections and legal compliance measures will be implemented.
Cardiac Rehab is a clinical assistance and educational tool.
The rehabilitation programs generated by the application are not officially medically validated and must not be considered final prescriptions without review by a qualified physician.
The application does not replace medical judgment, diagnostic expertise, or professional supervision.
Any use of generated exercise plans on real patients remains under the full responsibility of the user or supervising physician.
At its current stage, the application is not certified as a medical device.
We may update this Privacy Policy from time to time.
Changes will be published on this page.
