Privacy Policy for All-in-One Calculator Plus

Application: All-in-One Calculator Plus·Package ID: com.allinone.calculator.plus·Category: Tools & Utilities·Developer: RitualDev Studio

Core Privacy Mandate: 100% Offline Mathematical Processing

All-in-One Calculator Plus is engineered to execute 170+ modular calculators, financial amortizations, unit conversions, and health metrics 100% locally on your Android device. We believe your personal loan details, budget figures, scientific computations, and health markers belong solely to you. We do not collect, store, monetize, or transmit your calculation records to external cloud servers.

1. Information We Handle & Processing Categories

The application processes diverse calculations across several core modules. Here is how information within each module is handled:

FINANCIAL & LOAN CALCULATORS

Inputs such as mortgage balances, interest rates, EMI terms, investment principal, and tax brackets are computed exclusively in device RAM. No financial figures are logged remotely or used for credit profiling.

HEALTH & FITNESS CALCULATORS

Metrics including Body Mass Index (BMI), Basal Metabolic Rate (BMR), body fat percentage, and caloric needs are processed locally. No health data is stored in the cloud or synchronized with advertising partners.

SCIENTIFIC & ALGEBRA TOOLS

Matrix operations, polynomial equation solvers, trigonometry, and complex numbers are evaluated instantly via compiled native math engines without network dependence.

CALCULATION HISTORY & FAVORITES

Saved calculations and custom formula shortcuts are stored inside Android's private app sandbox SQLite database. This data never leaves your physical phone.

2. Android Permissions Scoping & Justification

All-in-One Calculator Plus operates with the strict principle of least privilege. The app requires no invasive permissions:

android.permission.INTERNETOptional Feature

Used solely when the user explicitly triggers the Currency Converter to fetch publicly available foreign exchange benchmark rates (e.g. from European Central Bank open APIs). No device identifier, location, or user identity is included in the rate request. If you are offline, cached historical exchange rates are used seamlessly.

Scoped Storage / PDF ExportUser-Initiated Action

When you choose to export an amortization schedule, invoice tally, or calculation breakdown as a PDF or CSV document, the app uses Android's Storage Access Framework (SAF) to save the file directly to your chosen local directory. We do not access other files on your storage.

3. Zero Telemetry & No Third-Party Tracking

RitualDev enforces strict engineering boundaries against covert user surveillance:

  • No Ad Networks: We do not integrate Google AdMob, Unity Ads, AppLovin, or any commercial ad bidding SDKs.
  • No Analytics Trackers: The application does not bundle Google Firebase Analytics, AppsFlyer, Adjust, or Facebook Graph SDKs.
  • No Device Fingerprinting: We do not read IMEI numbers, SIM serials, MAC addresses, or telephony IDs.

4. User Control, Data Ownership & Erasure

Because all calculation state resides on your hardware, you possess complete autonomy over your records:

Instant History Clear: Navigate to Settings > Clear All History inside the app to immediately wipe all calculation history and saved variables from SQLite storage.
Total Deletion on Uninstall: Uninstalling the application triggers Android's OS-level sandbox removal, permanently wiping all app databases, caches, and preferences from your storage.

5. Google Play Developer Program Policy Compliance

RitualDev certifies that All-in-One Calculator Plus complies fully with the Google Play Developer Program Policies, including Families Policy Requirements and Target API level guidelines. The app does not handle restricted personal data, is suitable for all ages, and requires no account creation or login credentials.
