Last Updated: August 2025

Introduction

Welcome to Healfie ("we," "our," or "us"). We respect your privacy and are committed to protecting your personal data. This Privacy Policy explains our privacy practices for our fully local mobile application ("App").

Important: Healfie is designed as a completely local application. All your health data remains on your device and no personal information is transmitted to our servers or any third-party services.

This Privacy Policy complies with the General Data Protection Regulation (GDPR) and other applicable EU data protection laws.

Local Data Processing

Since Healfie processes all data locally on your device, you maintain full control over your personal information. We do not act as a traditional data controller for your health data, as this information never leaves your device.

Information Processed Locally

Health and Fitness Data

With your explicit consent, the app accesses health and fitness data from Apple HealthKit for local processing, including:

  • Heart rate and heart rate variability (HRV)
  • Sleep metrics
  • Respiratory rate
  • Activity and workout data
  • VO2 max measurements

Important: All this health data is processed entirely on your device and never transmitted anywhere.

App Preferences and Settings

  • App preferences and settings (stored locally on your device)
  • User interface customizations

Legal Basis for Local Processing

Since all data processing occurs locally on your device, the primary legal basis is:

  • Consent: For accessing health data from Apple HealthKit
  • Legitimate Interest: For app functionality and providing health insights locally on your device

How Your Information is Used Locally

The app processes your information locally on your device to:

  • Provide health monitoring and analysis

  • Analyze trends and patterns in your health data
  • Display your health metrics and progress
  • Provide notifications and reminders

Note: All processing happens entirely on your device without any data transmission.

No Analytics or Tracking

Healfie does not use any analytics, error tracking, or monitoring services. The app operates entirely offline and does not send any data to external services or servers. Your privacy is completely protected as no information leaves your device.

HealthKit Data Usage

In accordance with Apple's requirements and our commitment to privacy:

  • We access HealthKit data solely to provide health and fitness services within our App
  • Your HealthKit data is processed entirely on your device and never leaves your device
  • We NEVER sell your HealthKit data to advertising platforms, data brokers, or information resellers
  • We NEVER use HealthKit data for advertising, marketing, or any external data-mining purposes
  • No HealthKit data is transmitted to any servers or third-party services

Data Storage and Security

  • All your health data is stored locally on your device in secure storage provided by iOS
  • Data is protected by your device's built-in security features including device encryption and biometric authentication
  • No data is transmitted to external servers or services
  • Your data is only accessible through the Healfie app on your device

Data Retention

Since all data is stored locally on your device, you have complete control over data retention. Your health data remains on your device for as long as you keep the app installed. You can delete all data by uninstalling the app or by using the data deletion features within the app settings.

Data Sharing

We do not share any personal information with third parties. Since all data processing occurs locally on your device, there is no data transmission to external services, servers, or third parties. Your health data remains completely private and under your exclusive control.

Local Health Analysis

Healfie provides health insights and analysis through local processing algorithms that run entirely on your device. There are no AI services or external health coaching features that require data transmission. All health analysis, insights, and recommendations are generated locally using your device's processing power, ensuring complete privacy.

Your Rights and Control

Since all data is processed locally on your device, you have complete control over your information:

  • Right to access: You can view all your data directly within the app
  • Right to rectification: You can correct or modify data within the app
  • Right to erasure: You can delete your data through app settings or by uninstalling the app

No formal requests are needed to exercise these rights since you have direct control through the app interface.

Age Restriction

Our App is intended for users 18 years and older. We do not knowingly collect personal information from anyone under 18 years of age. If we become aware that a person under 18 has provided us with personal data, we will take steps to delete such information.
