1. Overview

Tally It Down is a health and symptom tracking application ("the App"). We value your privacy and are committed to protecting your personal information. This Privacy Policy explains how we collect, use, store, and safeguard your information when you use our App.

2. Information We Collect

2.1 Authentication

The App uses Firebase Anonymous Authentication. This means:

  • No personal information is required to use the App
  • No email, name, or other identifiable data is collected
  • Firebase generates an anonymous user identifier (UUID) for each installation

2.2 Automatically Collected Information

  • Usage Data: App usage events and interactions for analytics purposes
  • Device Identifier: Anonymous user identifier (UUID) for authentication
  • Health Records: Mood, pain, energy, and sleep entries you create, behavioral tags, and tracking history
  • App Settings: Language preference, theme settings

3. How We Use Your Information

We use your information for the following purposes:

  • Provide Core Features: Enable health tracking, daily check-ins, data visualization, and pattern analysis
  • Authentication: Anonymous authentication via Firebase
  • Analytics & Improvement: Analyze usage patterns to improve app performance and user experience
  • Customer Support: Respond to your feedback, questions, and requests
  • Security: Detect, prevent, and address technical issues and security threats

4. Third-Party Services

The App uses the following third-party services:

Service Purpose Provider
Firebase Anonymous Authentication Anonymous user authentication Google LLC
Firebase Analytics App usage analytics and crash reporting Google LLC
Apple HealthKit Sleep data import (optional, user-initiated) Apple Inc.
StoreKit In-app purchases and subscriptions Apple Inc.

These third-party service providers process anonymous data only to perform specific tasks on our behalf and are obligated not to disclose or use it for any other purpose.

5. Data Storage & Security

5.1 Local Storage

  • All health records and settings are stored locally on your device
  • Data is isolated and protected by your anonymous user ID
  • Your data remains on your device and is not transmitted to any server

5.2 Security Measures

We employ the following security practices:

  • Anonymous authentication with no personal data collection
  • Anonymous user ID data isolation to prevent unauthorized access
  • Secure authentication mechanisms via Firebase
  • Regular security reviews and updates

6. Data Sharing & Disclosure

We respect your privacy and commit to:

  • Not Selling Your Data: We do not sell your information to third parties
  • No Personal Data Collection: We do not collect any personally identifiable information
  • Limited Sharing: We do not share your information except as described in this policy

We may share anonymous usage data only in the following circumstances:

  • Service Providers: With third-party service providers (e.g., Firebase) who perform services on our behalf
  • Legal Requirements: When required by law, court order, or government regulation
  • Protection of Rights: To protect our rights, property, or safety, or that of our users
  • Business Transfer: In connection with a merger, acquisition, or sale of assets

7. Health Data (Apple HealthKit)

The App optionally integrates with Apple Health to import sleep data. This integration:

  • Is initiated only by the user — the App never reads Health data without explicit permission
  • Only reads sleep-related data (bedtime, wake time, sleep duration)
  • Does not write any data back to Apple Health
  • All HealthKit data remains on-device and is never transmitted externally

8. Your Rights

Since the App does not collect personal information, there is no personal data for you to access, correct, or delete. Your health data is stored locally on your device and you have full control over it.

  • Local Data Control: You can delete the App at any time to remove all local data
  • Apple Health: You can revoke HealthKit access at any time in iOS Settings > Privacy & Security > Health

9. Children's Privacy

The App does not collect personal information and can be used by users of all ages. Parents and guardians should supervise children's use of the App.

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or for legal reasons. The updated policy will be published on this page, and we will notify users of significant changes through appropriate channels.

Your continued use of the App after the effective date of the revised Privacy Policy constitutes your acceptance of the updated terms.
