Privacy Policy

Effective Date: January 1, 2026 | Last Updated: February 9, 2026

Your Data Stays on Your Device. dA1ly is designed with a "local-first" architecture. Your health data never leaves your device unless you explicitly choose to back it up to your personal cloud storage (iCloud, Google Drive, etc.).

Our Commitment to Your Privacy

dA1ly ("we," "our," or "us") is committed to protecting your health information through privacy-by-design principles. This Privacy Policy explains how we handle your data. Unlike most health apps, we do not store your health information on our servers.

1. Information We Collect

Health Information (Stored Locally on Your Device Only)

  • Blood glucose readings and measurements
  • Food intake records and dietary information
  • Diabetes medication information
  • Symptoms and health observations
  • Mood and wellness indicators
  • Voice recordings (processed on-device for transcription, then deleted)
  • Health goals and targets

Important: All health data is stored exclusively on your device using AES-256 encryption. We cannot access this data, nor can we provide it to you if you lose your device. Please use the app's backup features to protect your data. We strongly encourage you to secure your device with a strong password, pin, or biometric authentication.

Analytics and Performance Data (Sent to Our Servers)

To improve the app, we collect limited, anonymized data:

  • App crash reports (no health information)
  • Feature usage statistics (e.g., "chat feature used 5 times")
  • Device type and operating system version
  • Anonymous performance metrics

This data cannot be linked to you or your health information. You can disable analytics in the app settings.

2. What We DO NOT Collect or Store

We explicitly do NOT:
  • Store your health data on our servers
  • Maintain user accounts or authentication systems except to track subscriptions and purchases.
  • Collect your name, email, or personal identifiers
  • Track your location
  • Sell any data to third parties
  • Share health data with advertisers or data brokers

3. How Your Health Data is Used

Your health data is used only on your device to:

  • Provide personalized diabetes management insights
  • Generate health summaries and trend visualizations
  • Offer AI-powered health recommendations (via on-device processing or encrypted API calls)
  • Alert you to concerning health patterns

AI Processing

We anonymize your data before sending it to any AI models for processing.

When you use AI features, health data may be sent to Google Gemini AI for processing. These interactions are encrypted and subject to Google's data handling policies. We recommend reviewing Google's privacy practices if you use AI features extensively.

We are reserve the right to change models that we use for AI processing at any time.

4. Your Data Rights and Control

Since your data lives on your device, you have complete control:

Access Your Data

  • View all your data within the app at any time
  • Export your data in JSON or CSV format via the app's export feature
  • Backups are stored locally on your device and can be exported to your personal cloud storage (iCloud, Google Drive)

Delete Your Data

  • Delete individual entries within the app
  • Clear all app data through your device's settings
  • Uninstall the app to remove all local data (ensure you have a backup first)

Note: Once deleted from your device, the data is gone permanently. We cannot recover it because we never had a copy.

Disable the App

In rare circumstances (such as a security vulnerability), we may remotely disable the app to protect users. You will be notified via in-app messaging if this occurs.

5. Data Security

On-Device Protection

  • AES-256 Encryption: All health data is encrypted at rest on your device
  • Secure Storage: Encryption keys are stored in your device's secure hardware (iOS Keychain / Android Keystore)
  • Local Processing: Most AI processing happens on-device to minimize data transmission
  • App Lock: Optional biometric/PIN protection within the app

Your Responsibilities

Because your data is local, you are responsible for:

  • Keeping your device secure (PIN, Face ID, Touch ID)
  • Creating regular backups to prevent data loss
  • Protecting your backup files (they contain your health data)

6. Data Backups

The app offers backup functionality to protect your data:

  • Automatic Backups: Backups can be scheduled in the app settings
  • Manual Export: Create manual backups anytime
  • Encrypted Backups: Backup files are encrypted with your device's security

Backups are stored in your cloud storage account (iCloud, Google Drive, etc.), not on our servers. We cannot access these backups unless you intentionally share them with us.

7. Children's Privacy

dA1ly is not intended for children under 13. We do not knowingly collect information from children under 13. For users 13-17, parental consent is recommended, and special care should be taken to protect health information on shared devices.

8. Changes to This Policy

We will notify you of material changes to this privacy policy:

  • In-app notification on next launch
  • Updated "Last Updated" date at the top of this policy
  • Details of changes available in the app's settings

9. Legal Basis for Processing (GDPR)

For users in the European Union, our legal basis for processing is:

  • Explicit Consent: For analytics and optional features (which you can disable)
  • Legitimate Interests: For app security, crash reporting, and fraud prevention
  • Contract: For providing the app's core functionality

10. Contact Information

For EU residents, you may also contact your local Data Protection Authority regarding any concerns.
