Carafe: Calm Water Tracker

1. Overview and Privacy Philosophy

DeveloperBits (“we”, “our”, or “us”) respects and protects your privacy. We engineered Carafe: Calm Water Tracker (package name: com.devbits.carafe) as a 100% offline, on-device hydration and habit tracking utility.

This Privacy Policy comprehensively discloses our data practices, permissions usage, and compliance with Google Play Developer Program Policies, COPPA, and international data protection regulations.

2. Data Collection and Data Handling

Carafe does not operate external servers, cloud databases, user account systems, or remote telemetry backends.

Information We DO NOT Collect

• No Personal Identifiers: We do not ask for or collect your name, email address, phone number, physical address, or account credentials.
• No Device Identifiers: We do not read, access, or track the Android Advertising ID (AAID), IMEI, MAC address, serial number, or hardware fingerprints.
• No Location Data: We do not request, access, or log your GPS, coarse network location, or Wi-Fi location.
• No Biometric or Sensitive Sensor Data: We do not access health sensors, heart rate monitors, step counters, or biometric sensors.
• No Media or Personal Files: We do not access your photo gallery, videos, audio recordings, or personal document directories.

Information Stored Exclusively on Your Device

The following information is created during your interaction with the app and resides solely within the application's private, sandboxed local database on your Android device:

• Hydration Entries: Volume logged (e.g. 250 ml), beverage type (water, tea, coffee, infusion), and local timestamp.
• Daily Targets: Daily hydration volume goal configured by the user.
• Quick Cup Presets: Custom container volume sizes and labels customized by the user.
• Reminder Settings: Selected waking hours, reminder intervals, and notification preferences.

None of this local data is ever transmitted, uploaded, or accessible to DeveloperBits or any third party.

3. Zero Internet Permission Disclosures

Carafe is designed to guarantee privacy at the operating system architecture level.

The few permissions declared in the application manifest are strictly limited to local device operation:

• android.permission.POST_NOTIFICATIONS: Required on Android 13 (API level 33) and higher to deliver your scheduled hydration reminders locally on your device. You can disable notifications at any time in Android Settings.
• android.permission.SCHEDULE_EXACT_ALARM / android.permission.USE_EXACT_ALARM: Used solely to trigger your chosen reminder intervals at accurate times while conserving battery.
• android.permission.RECEIVE_BOOT_COMPLETED: Used solely to reschedule your existing reminder alarms after your device is restarted.

Carafe requests zero dangerous runtime permissions for camera, microphone, contacts, storage, or phone state.

4. Zero Third-Party SDKs and No Advertising

Carafe is completely ad-free and tracker-free. The application contains:

• No Advertising SDKs: Zero integration with Google AdMob, Unity, AppLovin, ironSource, or any ad exchange network.
• No Analytics or Telemetry: Zero integration with Google Analytics, Firebase Analytics, Mixpanel, AppsFlyer, Adjust, or Sentry.
• No Social Media Trackers: Zero integration with Meta, TikTok, or other third-party SDKs.
• No Tracking Cookies: No web cookies, fingerprinting, or user profiling.

5. Data Retention, Export, and Deletion

Data Retention

Because all application data resides exclusively on your local device, data retention is entirely under your control. Data is retained in local storage for as long as you keep the app installed.

Data Export

Carafe allows you to optionally export your hydration logs as a standard CSV or JSON backup. When you initiate an export, Carafe writes the file solely to the destination you choose using Android's system Storage Access Framework. Carafe never synchronizes or uploads these exported files.

Data Deletion

You can permanently erase all stored hydration history and configuration at any time by:

• Using the in-app option to clear history.
• Navigating to Android Settings > Apps > Carafe > Storage & cache > Clear storage.
• Uninstalling the application from your device, which automatically purges all sandboxed database files.

6. Children’s Privacy (COPPA & Families Policy)

Carafe is a general-audience habit and hydration utility suitable for individuals of all ages. Because Carafe does not collect, store, or transmit any personal information from any user, it is fully compliant with the Children’s Online Privacy Protection Act (COPPA), the General Data Protection Regulation (GDPR), and Google Play’s Families Policy.

7. Changes to this Privacy Policy

We may update this Privacy Policy from time to time to maintain compliance with applicable laws and Google Play Developer Program policies. Any revisions will be published at this permanent URL with an updated effective date.
