Privacy Policy

Last updated: January 1, 2024

At AY Tech Systems, your privacy is our highest priority. This Privacy Policy explains our local-first approach to data storage in My Smoke Tracker and why your personal information never leaves your device.

Our Privacy-First Commitment

Smoke Tracker is built with privacy by design. Every aspect of the app is designed to keep your personal data completely private:

  • 100% Local Storage: All your smoking data is stored only on your device
  • No Cloud Sync: We never upload, sync, or store your smoking logs on any server
  • No Data Collection: We don't collect, analyze, or monetize your personal habits
  • No Third-Party Sharing: Your data never leaves your device, so it can't be shared
  • You Own Your Data: Export, delete, or keep your data entirely under your control

🔒 Why This Matters

Unlike other apps that sync your data to the cloud, Smoke Tracker's local-first approach means your sensitive smoking habits, triggers, and personal notes are never transmitted over the internet. This provides maximum privacy and security for your most personal health information.

Information We Collect

Data Stored Locally on Your Device Only

The following information is stored in a local SQLite database on your device and never transmitted anywhere:

  • Cigarette entries: Date, time, count, and personal notes for each smoking session
  • Trigger data: Situations, emotions, or contexts that led to smoking (stress, social, boredom, etc.)
  • User preferences: Daily limits, cost per pack, cigarettes per pack, theme settings
  • Progress statistics: Calculated metrics, trends, and patterns based on your data
  • Reminders: Custom notification schedules you set up
  • App settings: Theme preferences, haptic feedback, notification preferences

🏠 Local SQLite Database

All your data is stored in a SQLite database file on your device. This is the same technology used by many offline apps. The database file is encrypted by your device's built-in security and cannot be accessed by other apps or transmitted over the network.

Technical Information (Optional & Anonymous)

We may collect very limited, anonymous technical information to improve the app's stability and compatibility:

  • Crash reports: Anonymous technical data when the app unexpectedly closes (no personal data included)
  • Basic usage analytics: Anonymous data about app launches and feature usage (opt-in only)
  • Device compatibility: Device model and OS version for compatibility testing (anonymous)

Important: All technical data is completely anonymized and cannot be linked back to you, your identity, or your smoking data. You can opt out of analytics entirely in the app settings.

Note: Even crash reports and analytics are processed through privacy-focused services and contain zero personal information about your smoking habits or app usage patterns.

How We Use Your Information

Local Data Processing

Your smoking data is processed entirely on your device to:

  • Display your smoking history and patterns
  • Calculate statistics and trends
  • Identify triggers and provide insights
  • Track your progress toward goals

Technical Data

Anonymous technical data helps us:

  • Fix bugs and improve app stability
  • Understand which features are most helpful
  • Ensure compatibility across different devices
  • Plan future improvements

Data Sharing and Disclosure

We cannot share what we don't have. Since all your personal smoking data is stored locally on your device and never transmitted to our servers, we have nothing to sell, trade, or share with third parties.

Legal Requirements & Government Requests

We cannot comply with data requests because we don't have your data.Since your smoking logs, triggers, and personal notes are stored only on your device, there is no data on our servers for law enforcement, government agencies, or legal authorities to request or subpoena.

🛡️ Ultimate Privacy Protection

This local-first approach provides the strongest possible privacy protection. Even if compelled by law, we literally cannot access or provide your personal smoking data because it doesn't exist on any servers we control.

Third-Party Services (No Access to Your Smoking Data)

We work with the following services, but none of them have access to your smoking data:

  • App Stores: Apple App Store and Google Play Store handle app downloads and payments
  • RevenueCat: Manages premium subscriptions and in-app purchases (no smoking data access)
  • Crash Reporting: Anonymous crash reports help us fix bugs (no personal data included)

Important: Even these third-party services cannot access your smoking logs, triggers, or any personal health data because this information never leaves your device.

Your Data Rights

Data Ownership

You own all your data. Since it's stored locally on your device, you have complete control:

  • Access: View all your data within the app
  • Export: Export your data as a CSV file anytime
  • Delete: Clear all data or delete specific entries
  • Portability: Take your data to another app or service

Opting Out of Analytics

You can opt out of anonymous usage analytics in the app settings. This will not affect the app's functionality in any way.

Data Security

Your data security is ensured through our offline-first approach:

  • Local storage: Data stays on your device, protected by your device's security
  • No cloud sync: No risk of data breaches from our servers
  • Encryption: Data is encrypted using your device's built-in security
  • No tracking: We don't track you across apps or websites

International Data Transfers

Since your personal data is stored locally on your device and not transmitted to our servers, there are no international data transfers of your smoking logs or personal information.

Children's Privacy

Smoke Tracker is intended for adults (18+) and we do not knowingly collect information from children under 18. If you believe a child has used our app, please contact us at aytech.systems@gmail.com.

Changes to This Privacy Policy

We may update this Privacy Policy occasionally to reflect changes in our practices or for other operational, legal, or regulatory reasons. We will notify users of any material changes through the app or our website.
