Overview

TinyHabit is a minimalist habit tracking application that helps users build better daily routines. The app allows users to create custom habits, track daily completions, receive smart reminders, and visualize their progress through interactive charts and statistics. Users can customize habits with icons, colors, and schedules, monitor streaks, and analyze their consistency over time.

Key Features:

• Create and manage daily habits with custom goals
• Track completion status with one-tap marking
• View progress through charts (line charts, pie charts, progress bars)
• Monitor streaks and completion rates
• Receive local notifications as reminders
• Customize habits with icons, colors, and schedules
• Multi-language support (English, Spanish, French, Portuguese, Hindi, Vietnamese)

Information Collection and Use

TinyHabit is designed with privacy as a core principle. The app operates entirely offline and does not collect, transmit, or store any personal information on external servers.

Data Storage:

• Local Database: All habit data, completion records, and app settings are stored locally on your device using SQLite database. This includes:
  • Habit names, descriptions, goals, and configurations
  • Daily completion records and progress tracking
  • User preferences (theme, language, notification settings)
  • Streak counts and statistics
• SharedPreferences: App settings and user preferences are stored locally using SharedPreferences for quick access.
• No Cloud Sync: We do not upload, sync, or store any of your data on external servers or cloud services.
• No Analytics: We do not use any analytics services to track your usage or behavior within the app.

The app does NOT collect:

• Personal identification information (name, email, phone number)
• Location data
• Device identifiers for tracking
• Usage analytics or telemetry
• Contacts or media files
• Any data that could identify you personally

Permissions

The app requires the following permissions to function properly:

• Storage Access (Optional): May be requested in future versions if you choose to export your habit data as a backup file. Currently not implemented.

All permissions are used solely for their stated purposes. The app does not use these permissions to collect or transmit any personal data.

Data Storage and Security

All your data is stored locally on your device and is protected by your device's security measures. We implement the following practices:

• Local-Only Storage: All data remains on your device using SQLite database and Android SharedPreferences.
• No Network Transmission: The app does not connect to the internet or transmit any data to external servers.
• Data Isolation: Your habit data is stored in the app's private directory, inaccessible to other apps without root access.
• Device Security: Data security relies on your device's lock screen, encryption, and security features.

If you uninstall the app, all locally stored data will be permanently deleted from your device according to Android's standard app uninstallation process.

Third-Party Services

TinyHabit does not integrate with any third-party services, analytics platforms, advertising networks, or cloud services. The app functions entirely offline and independently.

We do NOT use:

• Google Analytics or Firebase Analytics
• AdMob or any advertising services
• Crash reporting services (Crashlytics, Sentry, etc.)
• Cloud storage or backup services
• Social media integrations
• Any third-party SDKs that collect user data

The only third-party dependencies used are open-source libraries for UI components and local database management, which do not collect or transmit any data:

• Drift: Local SQLite database management
• Provider: State management framework
• fl_chart: Chart rendering library
• flutter_local_notifications: Local notification scheduling

No Personal Data Collection

TinyHabit is committed to protecting your privacy. We do not collect, store, process, or transmit any personally identifiable information (PII). The app:

• Does not require account creation or login
• Does not ask for your name, email, or any personal details
• Does not track your location
• Does not access your contacts, photos, or other personal files
• Does not use device identifiers for tracking or advertising
• Does not share any data with third parties

All habit names, descriptions, and notes you create are stored only on your device and are never transmitted anywhere.

Notifications and Reminders

TinyHabit uses local notifications to remind you about your habits. These notifications:

• Are generated entirely on your device
• Do not require internet connection
• Do not send any data to external servers
• Can be customized or disabled at any time in app settings
• Use Android's notification system (respect Do Not Disturb mode)

You can manage notification permissions in your device's system settings or within the app's notification settings screen.

Data Backup and Export

Currently, TinyHabit: StreakMaster does not include automatic backup or cloud sync features. All your data is stored locally on your device. If you:

• Uninstall the app: All habit data and settings will be permanently deleted.
• Clear app data: This will erase all habits, completion records, and preferences.
• Switch devices: Your data will not automatically transfer to the new device.

Future versions may include manual export/import functionality, allowing you to save your habit data to a file on your device for backup purposes. Any such feature will remain entirely local and under your control.

Children's Privacy

TinyHabit is suitable for users of all ages, including children. The app does not collect any personal information from anyone, including children under the age of 13.

The app is designed to be safe for children with:

• No social features or chat functionality
• No external links or web content
• No data collection or tracking
• No advertisements
• No in-app purchases

Parents can feel confident that their children can use TinyHabit: StreakMaster without any privacy risks.

International Users and Data Protection

TinyHabit respects international privacy laws including GDPR (Europe), CCPA (California), and other regional regulations. Since the app:

• Does not collect personal data
• Stores all data locally on your device
• Does not transmit data to servers
• Does not use tracking or analytics

There are no concerns regarding cross-border data transfers, data controller relationships, or compliance with data subject rights (access, deletion, portability) since we never have access to your data in the first place.

GDPR Compliance (European Users)

Under the General Data Protection Regulation (GDPR), users have specific rights regarding their personal data. However, since TinyHabit:

• Does not collect or process personal data
• Does not store data on external servers
• Operates entirely offline on your device

GDPR rights such as data access, rectification, erasure, and portability are inherently satisfied because you have complete control over your data at all times. You can view, modify, or delete your habit data directly within the app at any time.

TuanDQ Co. is not a data controller or processor for your habit data since we never have access to it.

CCPA Compliance (California Users)

Under the California Consumer Privacy Act (CCPA), California residents have rights regarding their personal information. TinyHabit:

• Does not sell personal information
• Does not share personal information with third parties
• Does not collect personal information for commercial purposes

Since we do not collect personal information, CCPA rights such as the right to know, right to delete, and right to opt-out of sale do not apply.

Changes to This Privacy Policy

We may update our Privacy Policy from time to time to reflect changes in the app's functionality or legal requirements. We will notify you of any changes by:

• Posting the new Privacy Policy on this page
• Updating the "Effective Date" at the top of this document
• Displaying an in-app notification if significant changes occur

You are advised to review this Privacy Policy periodically for any changes. Changes are effective immediately after they are posted on this page.

Your Rights and Control

With TinyHabit, you have complete control over your data:

• View Data: All your habit data is visible within the app at any time
• Modify Data: Edit or update habits and completion records directly in the app
• Delete Data: Remove individual habits or clear all data from settings
• Disable Features: Turn off notifications or other features at any time
• Uninstall: Completely remove the app and all associated data from your device

You never need to contact us to exercise these rights since all data management happens locally on your device.

Security Practices

While TinyHabit does not collect data, we implement security best practices in app development:

• Use of SQLite database with proper query parameterization to prevent injection attacks
• Secure coding practices following Flutter and Dart guidelines
• Regular dependency updates to address security vulnerabilities in third-party libraries
• No sensitive data exposure through logs or debug information

Your data security primarily depends on your device's security measures such as lock screen, encryption, and system security updates.

Open Source and Transparency

TinyHabit: StreakMaster is committed to transparency. Users can verify our privacy claims by:

• Reviewing the app's permissions in Android system settings
• Monitoring network activity (the app makes no network requests)
• Inspecting the local database stored on your device

We believe in building trust through transparency and verifiable privacy practices.
