1. Our Privacy Pledge

At Alco Track, we believe tracking personal alcohol consumption requires complete, uncompromised confidentiality. We do not require accounts, we do not operate cloud databases, and we do not track your behavior.

This Privacy Policy explains how Alco Track handles your information on iOS and Android devices. Because the application operates entirely offline and locally, you are in complete physical custody of your personal data at all times.

2. What We DO NOT Collect

Unlike conventional lifestyle and health apps, Alco Track does not communicate with external servers or cloud services:

No Personal Identifiers: We do not ask for or collect names, email addresses, phone numbers, birthdates, or user credentials.
No Account Registration: The application functions immediately upon installation without requiring an account or sign-in.
No Tracking or Analytics SDKs: We do not integrate Google Analytics, Firebase, Mixpanel, AppsFlyer, or any remote telemetry.
No Advertising Identifiers: We never access Apple's Identifier for Advertisers (IDFA) or Google's Advertising ID.
No Location Data: We do not request, monitor, or store GPS or geolocation coordinates.
No Third-Party Data Sharing: Your records are never sold, rented, or transferred to insurance providers, advertisers, or researchers.

3. Data Stored Locally on Your Device

All records generated during your use of Alco Track remain solely on your physical device within the application's isolated sandbox storage (via encrypted local SQLite and SharedPreferences):

Data Category	Examples	Storage Location
Drink Entries	Beverage name, category, volume (ml), ABV (%), units, price, timestamp, and notes	Local SQLite Database
Custom Catalogue	Custom drink items and pinned favorites created by you	Local SQLite Database
User Settings	Weekly unit goal, currency symbol, dark/light theme, and first-day-of-week	Device SharedPreferences
Security Preference	Whether biometric lock is enabled on launch	Device SharedPreferences

4. Biometric Authentication (Face ID / Fingerprint)

If you choose to enable the Biometric App Lock feature:

Authentication is performed exclusively by the operating system's native hardware security subsystem (Apple LocalAuthentication framework on iOS, or Android BiometricPrompt).
Alco Track never accesses, scans, or stores your biometric facial or fingerprint data.
The operating system provides only a cryptographic confirmation of successful identity verification to unlock the interface.

5. In-App Purchases & Payment Processing

Alco Track offers an optional one-time in-app purchase to unlock Pro features. All payment transactions are executed directly by the platform operators:

Apple App Store (iOS): Managed by Apple StoreKit. Subject to Apple's Media Services Terms and Privacy Policy.
Google Play Store (Android): Managed by Google Play Billing. Subject to Google Payments Terms of Service and Privacy Policy.
Zero Access to Financial Information: Alco Track never collects, accesses, transmits, or stores your credit card details, debit card numbers, bank account numbers, or billing addresses.
Local Entitlement Verification: Upon successful purchase or restore, the platform returns a digitally signed receipt/token directly to your device. This verification is evaluated locally and saved in device preferences to unlock Pro features without requiring an external server or account.

6. Clinical PDF Reports & JSON Data Exports

Alco Track includes tools to export your consumption history for consultation with healthcare providers or personal backups:

PDF Clinical Reports: Rendered directly on-device using a local PDF engine without transmitting data across any network.
JSON Backup Files: Formatted locally from your SQLite database.

When you choose to export (via Apple Files, Android Downloads, Email, or Messaging), the action is initiated solely by you via your operating system's native share sheet. Alco Track never receives or transmits copies of these files.

7. Data Deletion, Portability & Ownership (GDPR & CCPA)

You have absolute ownership and control over your information:

Right to Erasure: You can delete any individual drink entry, or erase your complete history at any time via Settings > Danger Zone > Delete All Data.
Right to Portability: You can export all your drink history at any time in standardized JSON or PDF formats.
App Deletion: Removing Alco Track from your device automatically and irrevocably purges all local app data from your device storage.

8. Medical & Health Disclaimer

⚠️ Important Clinical Notice

Alco Track is an informational self-monitoring tool, not a medical device or diagnostic instrument.

Unit calculations and Blood Alcohol Concentration (BAC) estimations are mathematical approximations based on UK Chief Medical Officers' guidelines and general population averages. They must never be used to assess fitness to drive or operate machinery.

Dependency Warning: Individuals with severe physical alcohol dependency must never discontinue alcohol abruptly without professional medical supervision, as doing so can trigger life-threatening withdrawal complications. Please seek immediate clinical assistance.
