Age Calculator

Welcome to Age Calculator ("we", "our", or "the App"). This Privacy Policy governs your use of the Age Calculator mobile application for Android devices (Application ID: com.calculatorage.apk).

We are committed to absolute transparency regarding how information is handled. Because trust is our highest priority, our application has been built from the ground up as a local-first, privacy-respecting utility. We do not operate remote account servers, nor do we collect, harvest, or monetize your personal or sensitive health data.

The App processes only the specific pieces of data that you affirmatively choose to input to enable the application's mathematical calculation features:

Data We Do NOT Collect:

• No Location Data: We never request or access GPS, coarse location, or cell-tower data.
• No Contact Lists: We do not access your phonebook or address book.
• No Media or Files: We do not read your photo gallery, videos, or external storage files.
• No Biometric Sensors: We do not interface with fingerprint, iris, or facial recognition hardware.
• No Hardware Identifiers: We do not collect or log IMEI, MAC address, Android ID, or Advertising ID (GAID).

All profiles and milestones are managed using an embedded, sandboxed Android Room SQLite database. This database is stored exclusively within the application's private, operating system-protected directory:

/data/data/com.calculatorage.apk/databases/age_calculator.db

Android's application sandboxing ensures that no other app installed on your device can inspect, read, or tamper with your stored age calculator data without root privileges. Furthermore, no background service or daemon transmits this database over the network.

Age Calculator includes a lifestyle-based Biological Age & Longevity Calculator. In compliance with Google Play Developer Program policies regarding health apps and sensitive data:

Any biomarker data entered into the biological age screen is processed synchronously in device memory and discarded or saved locally to your device at your choice. It is never transmitted to medical registries, health insurance companies, or pharmaceutical networks.

We strictly enforce a zero third-party disclosure policy:

• We do NOT sell: We never sell, rent, trade, or monetize your personal information to anyone.
• We do NOT share: We do not transmit profile, age, or health data to advertisers, telemetry aggregators, or brokers.
• No Tracking SDKs: The application contains no third-party behavioral analytics or advertising libraries.

In strict adherence to Google Play policies concerning the principle of least privilege, Age Calculator avoids requesting sensitive or dangerous runtime permissions:

• No Camera or Microphone Permission: The app has zero audio/video recording capabilities.
• No Location Permissions: No ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION.
• No Storage Permissions: The app utilizes zero-permission internal sandboxed app storage.
• No Contacts/Calendar Permissions: Milestone dates are maintained internally and do not access external device calendars.

Under Google Play Console User Data policies and privacy legislation, you possess absolute sovereignty over your data:

How to Delete or Clear Your Data:

• Delete Individual Profiles: Navigate to the Profiles & Settings tab in the app, select any saved profile, and tap the Delete button to instantly remove it from the local database.
• Delete Custom Milestones: Open the Milestones screen, locate the custom milestone, and tap the trash icon.
• Reset All Data via Android Settings: Open Android Settings > Apps > Age Calculator > Storage > Clear Data to wipe all local preferences and databases.
• Complete Application Uninstallation: Uninstalling the Age Calculator app immediately and permanently purges all SQLite databases and preference files from your device.

Age Calculator is suitable for all age groups, including families tracking birthdays of children, infants, and pets.

In compliance with the Children's Online Privacy Protection Act (COPPA), the General Data Protection Regulation (GDPR Article 8), and Google Play's Families Policy:

• We do not knowingly collect personal identifiable information (PII) from children under the age of 13 (or under 16 in applicable European jurisdictions) through any online mechanism.
• Any child birthdates or names entered by parents or guardians exist exclusively on the local hardware device.
• The app displays zero targeted advertising, behavioral tracking, or social networking features.

Regardless of your country of residence, we respect your fundamental privacy rights:

• Right to Know & Access: You can view all saved data directly through the interactive screens of the application.
• Right to Rectification: You can edit any profile, milestone, or biomarker metric at any time.
• Right to Erasure ("Right to be Forgotten"): You have full power to delete any item or wipe the database as described in Section 7.
• Right to Data Portability: The app provides an in-app "Share / Export Summary" button that copies your computed age metrics directly to your system clipboard for your personal records.
• Right to Non-Discrimination: We provide identical features to all users without discrimination.

We adhere to rigorous mobile security practices:

• Sandboxed Isolation: We rely on Android's Linux user-based process isolation (UID separation).
• Zero Remote Transmission: Because data is not transmitted across public cellular or Wi-Fi networks, your data is completely immune to Man-in-the-Middle (MitM) interception or remote cloud server breaches.
• Input Validation: All user inputs are validated prior to database persistence to prevent injection attacks or memory corruption.

We may occasionally update this Privacy Policy to reflect app enhancements or statutory updates. When changes are made, the "Effective Date" at the top of this document will be updated. Because we do not store email addresses or user accounts, we encourage you to review this policy periodically. Continued use of the application constitutes acceptance of any revisions.
