Thank you for choosing SparkFast App. Your privacy and the security of your data are a top priority for us. This Privacy Policy explains what information we collect, why we collect it, and how you can manage and delete your information.
1. Information We Collect
To provide and personalize your experience, we collect several types of information:
- Account Information: When you create an account, we collect your full name, email address, and a securely stored password. This is necessary to create your account, allow you to sign in, and secure your data.
- Onboarding & Profile Information: During setup, we ask for information to tailor the app to you. This includes your
fasting experience level, primary health goals, and dietary preferences. - Health & Wellness Data (Optional): You have the option to provide and sync health data to track your progress. This includes:
- Manual Entries: Data you choose to log directly in the app, such as your weight, sleep, hydration (water), electrolyte intake, mood, and text notes about your refeed experience.
- Health App Integrations: If you grant permission, we access specific data from third-party services like Apple Health or Keto-Mojo. The data we request read-access for includes
Weight, HRV, Sleep, Steps, Ketones, and Glucose. - Progress Photos: The app allows you to upload full-body pictures to visually track your progress. This feature is entirely optional, and these photos are treated as highly sensitive personal data.
- App Usage Data: We automatically store a history of your activities within the app, such as the type and duration of your completed fasts, and the refeed plans you follow. This allows you to review your history and track trends over time.
- Subscription Information: We receive purchase confirmation from the App Store to validate your subscription status, but we do not collect or store your payment details like credit card numbers.
2. How We Use Your Information
We use your data to make SparkFast a powerful and personal tool for you:
- To Provide Core App Functionality: We use your data to run the Fasting Engine , manage your
Active Fast Dashboards , and provide a complete
history of your fasts. - To Personalize Your Experience: Your onboarding answers and health data are used to power our Smart Suggestions for the Refeed Protocol Engine and to trigger relevant messages from the
Motivational Engine. - To Visualize Your Progress: We use your synced and manually logged data to display your progress on the Biomarker Tracker charts.
- To Communicate With You: We use your information to send push notification reminders for hydration and refeed steps (if you enable them) and to respond to support requests.
We will never sell your personal data to third parties.
3. How We Store and Protect Your Information
Your data's security is critical.
- All your information is stored securely using Google's Firebase services. This includes your account information, health data, and any photos you upload.
- Progress photos are stored with a high level of security and are only visible to you within your private account.
- You can choose to export your data at any time in
PDF or CSV format. This process is handled securely on your device.
4. Your Rights and Choices
You are in control of your data.
- Access and Update: You can review and update your profile information and app preferences at any time in the App Settings screen.
- Data Integrations: You can connect or disconnect services like Apple Health at any time from the settings menu.
- Delete Your Data: You can delete individual data points, such as progress photos, at any time. You can also choose to delete your entire account from the settings page, which will permanently remove all your associated data from our systems.
