OneCalc is a calculator and utility app designed to work primarily on your device. You do not need an account or login to use the app, and OneCalc does not operate a backend service for storing your calculations.
This Privacy Policy explains what information OneCalc stores, when information may leave your device, and how you control your data.
OneCalc does not collect, sell, or share personal information for advertising or tracking purposes.
Your calculations, saved scenarios, favorites, settings, and calculation history are stored locally on your device.
OneCalc does not use advertising, analytics, or tracking services in the current release.
OneCalc stores certain information locally so that its features work correctly. Depending on the features you use, this may include:
Information
Purpose
Storage
Calculation history
To view and reuse previous calculations
On your device
Favorite calculators
To customize your Home screen
On your device
Saved scenarios
To save and compare calculations
On your device
App settings
To remember preferences such as theme, currency, decimal places, and angle mode
On your device
Cached exchange rates
To allow currency conversion while offline
On your device
This information is stored in the app's private local storage/database and is not uploaded to a OneCalc server.
Uninstalling OneCalc generally removes its locally stored app data according to your device's operating-system behavior.
You can also delete calculation history from Settings → Privacy → Clear History.
OneCalc is designed to work offline.
The app only uses an internet connection when you manually request an exchange-rate refresh.
When you tap Refresh in the Currency Converter, OneCalc sends the information required to request exchange rates from its configured exchange-rate service. This may include the selected base currency and other technical information normally required to make an internet request, depending on the service and your operating system.
Your calculations and saved personal content are not included in the exchange-rate request.
If you do not refresh exchange rates, OneCalc can continue using exchange rates already stored on your device.
Offline exchange rates are identified with their applicable date and are not presented as live rates.
OneCalc may request or use:
INTERNET — Used only for optional exchange-rate updates.
Biometric authentication — Used when you enable the optional app lock. Biometric authentication is performed by your device's operating system. OneCalc does not receive, access, or store your fingerprint or facial biometric data.
OneCalc may use the operating system's biometric authentication features, such as Face ID or Touch ID, when you enable the optional app lock.
OneCalc does not access your contacts, location, camera, microphone, or other device data unless a future feature specifically requires such access and this policy is updated accordingly.
When you choose to import or restore a backup, OneCalc accesses the file that you explicitly select through the operating system's file picker.
OneCalc provides features to copy, share, or export calculation results.
When you use Copy, the result is provided to your device's clipboard.
When you use Share, the content is passed to your device's standard sharing interface so that you can choose another app or destination.
When you use Export PDF or Export CSV, the file is created on your device and you choose what to do with it.
OneCalc does not upload these exported results to a OneCalc server.
OneCalc may allow you to create a local backup containing information such as calculation history, favorites, saved scenarios, and app settings.
Backups are created and controlled by you. If you share, upload, or store a backup using another service, that service's privacy policy applies to your use of that service.
OneCalc does not automatically upload your backups to the cloud.
OneCalc includes general health and fitness calculators such as BMI, BMR, TDEE, ideal weight, and body-fat estimates.
These tools are intended for general informational and wellness purposes. They do not provide medical diagnosis, treatment, or medical advice and should not be used as a substitute for consultation with a qualified healthcare professional.
Health-related values entered into these calculators are processed locally by the app and are not intentionally transmitted to OneCalc servers.
OneCalc includes calculators for features such as EMI, loan prepayment, SIP, FD, GST, discounts, and other financial calculations.
These tools provide mathematical estimates based on the information and assumptions entered by the user. They do not provide loans, investment products, banking services, or personalized financial advice.
Financial results are estimates and should not be considered guaranteed outcomes.
The current version of OneCalc does not include:
Advertising SDKs
Analytics SDKs
Crash-reporting services
User tracking services
Account or login systems
Cloud synchronization for calculations
OneCalc does not sell personal information.
If a future version introduces a service that changes how personal information is collected, processed, or shared, this Privacy Policy will be updated before or when that functionality becomes available.
OneCalc does not knowingly collect personal information from children.
The app does not require an account or request personal information to perform its calculator functions.
Parents or guardians who have questions about the app's data practices can contact us using the details below.
OneCalc is designed to keep your calculation data on your device. You are responsible for protecting access to your device and for deciding where you store or share any exported files or backups.
No method of electronic storage or transmission can be guaranteed to be completely secure.
We may update this Privacy Policy when OneCalc's features or data practices change.
The Last updated date at the top of this page will be changed whenever the policy is revised. Material changes will be reflected in the updated policy before or when the relevant functionality is introduced.
