3. Information We Collect

VitalFlow processes only the essential information needed to track, calculate, and visualize your daily wellness journey.

A. User Profile Information

To establish customized body metrics, calorie projections, and hydration index formulas, you can configure a profile with the following:

  • Personal Identity: Your chosen Name or Nickname.
  • Demographics: Date of Birth (Age) and Gender.
  • Body Composition: Height, Weight, Waist Circumference, and Body Fat Percentage.
  • Medical Baseline: Blood Group and Allergies (stored securely offline for user self-reference).

B. Health, Activity & Lifestyle Logs

VitalFlow lets you log and monitor your daily wellbeing patterns. This data is recorded directly into your personal database:

Activity Logs

Pedometer step logs and step targets mapped to your physical movement.

Hydration Logs

Detailed records of daily water intake and customized water goals.

Vitals tracking

Systolic & diastolic blood pressure, heart rate, and body temperature.

Sleep & Habits

Sleep duration and custom habits with strict daily completion streaks.

Additionally, the App records Mood Logs, Diary Entries (journaling notes), Yoga Sessions (yoga practices and poses), and Alarm Configurations with custom audio tunes.

4. Device Permissions Required

The App requests standard system-level permissions to provide full interactivity. You can grant or revoke these at any time via your operating system settings:

  • Physical Activity / Pedometer: Required on mobile platforms to interact with the device's built-in step counter sensors for automatic daily tracking.
  • Notifications & Alarms: Essential for triggering customized medication cues, water reminders, habit nudges, and scheduled alarms.
  • Local Storage (Optional): Required only if you select a personal sound file (.mp3) from your local music folders to provision as a custom alarm ringtone.

5. How We Use Your Information

Your logged parameters and configurations are processed strictly for the following purposes:

  • To run the core calculations of the application (e.g., Body Mass Index (BMI), daily target calculations, and habit compliance logs).
  • To render interactive, beautiful charts and history dashboards.
  • To execute scheduled alarms and alarms with custom sounds.
  • To securely back up and synchronize your profile parameters across multiple devices via cloud storage if enabled.

6. Data Storage & Security

VitalFlow utilizes a secure, user-centric hybrid data management architecture:

A. Local Device Sandbox (Offline-First)

Almost 100% of your generated logs, step tracking history, habit schedules, alarms, and personal journal notes are written directly to a highly secure SQLite database (vitalflow.db) residing strictly in your device's application sandbox (AppDataDirectory).

  • This data is fully offline, private to your hardware, and completely inaccessible by any external applications.
  • Uninstalling the App will completely purge the local SQLite database.

B. Cloud Sync (Google Firebase)

For cross-device continuity, the App synchronizes certain metadata securely with a Google Firebase Realtime Database:

  • Only your User Profile properties are backed up to the Firebase cloud server.
  • Data is fully encrypted in transit using industry-standard Secure Sockets Layer (SSL/TLS) mechanisms.
  • Firebase Realtime Database access is governed by strict Security Rules restricting read/write capabilities to authorized user references.

7. Sharing Your Information

We do not sell, license, rent, trade, or monetize your health or personal records with third-party advertising networks, data brokers, or analytics corporations under any circumstances.

Your data is only shared with third parties under the following extreme scenarios:

  • Direct User Action: If you manually choose to export your reports or copy logs to share with your personal healthcare professional.
  • Legal Obligations: If we are required to disclose user information to satisfy laws, administrative search warrants, or court subpoenas.

8. Third-Party Services

We integrate a single reliable cloud provider to administer profile backup services:

  • Google Firebase Realtime Database: Manages the optional profile backup sync and serves educational health articles. For more information, please examine the Google Firebase Privacy Statement.

9. Your Rights & Control (GDPR / CCPA)

Regardless of your geographic region, we provide extensive control over your data, reflecting the core principles of GDPR and CCPA:

  • Access & Modify: You can view, edit, or revise your logs, habits, profile metrics, and vitals at any time directly in the VitalFlow interface.
  • Data Erasure: You can completely destroy your local data instantly by clearing the App's storage cache or uninstalling the App. To request deletion of synced Firebase profiles, you can reach out directly via our support email.
  • Manage Permissions: You can disable pedometer sensor or notification access at any point within your device's System Settings.

10. Children's Privacy

VitalFlow is designed as a self-tracking utility for adult and adolescent health tracking. We do not knowingly or actively solicit or collect data from children under 13 years of age. If you discover that a child has created a profile without parental supervision, please contact us immediately, and we will take immediate steps to remove the synced profile data from our servers.
