1. Overview & Scope
This Privacy Policy governs the manner in which the Dairy Tools mobile application for Android (package name: com.snc.dairytools, referred to as "the App", "we", "our", or "us") handles information when you use our software.
Dairy Tools is an operational utility engineered for dairy farmers, plant operators, dock testing workers, and dairy laboratory professionals. We are committed to transparency regarding how data is processed, what device permissions the app requires, and how third-party advertising and analytics services operate within the app.
Summary: Dairy Tools does not require user account registration, passwords, phone numbers, or email sign-ins. All dairy formulas, lactometer calculations, and tank countdown timers are executed directly on your device.
2. Local Data Processing & Storage
Dairy Tools is designed to function primarily as an offline calculation tool. We do not maintain user databases or transmit your dairy production numbers to our servers.
Calculation Inputs
All numerical values you enter (such as Milk Fat %, Solid-Not-Fat %, Corrected Lactometer Readings, milk quantities, temperature adjustments, and product yield variables) are processed in volatile memory on your device solely to calculate the instantaneous result. These inputs are not logged, transmitted, or sold.
App Preferences (SharedPreferences)
To provide a seamless user experience across app sessions, the app stores the following non-personal configuration settings locally on your device via Android's SharedPreferences:
- Selected Interface Language: Remembers your chosen language (e.g., English, Hindi, Bengali, Gujarati, Marathi, etc.).
- Display Theme: Remembers whether you selected Light Theme, Dark Theme, or System Default.
- Ad-Free Status: Stores a verification flag if you purchase the ad-free upgrade through Google Play Billing.
3. Android Permissions & Hardware Usage
To enable reliable background operation of the Milk Tank Timer and alert features, Dairy Tools requests the following specific Android permissions:
| Permission | Exact Purpose in Dairy Tools |
|---|---|
WAKE_LOCK |
Prevents the device's processor from sleeping during an active Milk Tank countdown, ensuring precise agitation and chilling timing. |
MODIFY_AUDIO_SETTINGS |
Allows the app's alarm player to trigger the completion alarm sound (alarm_sound.mp3) when the set milk agitation cycle expires. |
FOREGROUND_SERVICE |
Runs the tank timer service in the foreground so the countdown continues accurately if you navigate to another app or turn off the screen. |
FOREGROUND_SERVICE_MEDIA_PLAYBACK |
Authorizes media audio playback for the completion alarm while running as a foreground service. |
POST_NOTIFICATIONS |
Required on Android 13 (API level 33) and newer to show countdown progress and notification alerts when your milk tank cycle finishes. |
Dairy Tools does not access your contacts, GPS location, microphone, SMS, calendar, or financial accounts.
4. Third-Party Services & Advertising (Google AdMob)
To support ongoing development and keep the core suite accessible, Dairy Tools integrates industry-standard third-party SDKs provided by Google LLC. These services may collect pseudonymous device information:
A. Google Mobile Ads (Google AdMob)
The app displays banner and interstitial advertisements provided by Google AdMob. AdMob may automatically collect and process certain data to serve, measure, and optimize ads, including:
- Google Advertising ID (GAID / AAID)
- Coarse IP address (used for approximate region / country routing)
- Device model, manufacturer, and operating system version
- Ad interaction metrics (impressions, clicks, views)
You can control or reset your Android Advertising ID at any time via your device settings:
Settings > Google > Ads > Reset Advertising ID / Delete Advertising ID

Google Advertising Privacy & Terms
B. Firebase Services (Google LLC)
The app utilizes Firebase (Project: dairy-tools-87dea) for crash analytics and diagnostic events to resolve software defects and maintain application stability across different Android device models. These diagnostics are pseudonymous and do not contain personal identities.

5. In-App Purchases & Financial Data
Dairy Tools offers an optional in-app purchase allowing users to remove advertisements. All purchases and billing transactions are processed exclusively through Google Play In-App Billing.
Dairy Tools never receives, processes, or stores your credit card numbers, bank account numbers, or billing addresses. All financial transactions are secured and managed directly by Google Play under Google’s terms of service.
6. Data Security & Retention
Because Dairy Tools does not maintain external user accounts or transmit your calculations to external database servers, your operational dairy records remain strictly within your device's private sandbox storage.
You can erase all locally stored preferences at any time by clearing the application's data through your Android device settings (Settings > Apps > Dairy Tools > Storage > Clear Storage) or by uninstalling the application.
7. Children's Privacy
Dairy Tools is an industrial and commercial utility created specifically for agricultural workers, dairy professionals, and laboratory technicians. The application is not directed toward children under 13 years of age (or under 16 in the European Economic Area). We do not knowingly collect personal information from children.
8. User Rights & Privacy Controls (GDPR & CCPA/CPRA)
Under applicable data protection laws (including the EU General Data Protection Regulation and California Consumer Privacy Act), you retain rights regarding your information:
- Right to Restrict Tracking: You can opt out of personalized ads at any time via Android's native Settings.
- Right to Deletion: Uninstalling the application immediately and permanently removes all locally stored preferences from your hardware.
- No Sale of Personal Data: We do not sell, rent, or trade personal information to data brokers or marketers.
