App Name: Post Office Interest Calculator
This Privacy Policy explains how Post Office Interest Calculator handles information when you use our mobile application.
The app helps users calculate interest, estimated maturity amounts, year-wise returns, and historical interest calculations for Indian Post Office savings schemes, including RD, MIS, TD, NSC, SCSS, KVP, SSA, and SB.
By using the app, you acknowledge the practices described in this Privacy Policy.
The app allows you to enter information such as investment amounts, deposit amounts, and investment periods to calculate interest and maturity values.
These details are used to perform the calculations you request. If these details are processed and stored only on your device, we do not receive them through our own servers.
This statement applies only if the app does not transmit these entries to Firebase or another external service.
Depending on the integrated SDKs and their configuration, third-party services may automatically collect or process information such as:
Device model, operating system, and app version.
App usage information, including app launches and interactions.
Crash reports, diagnostics, and performance information.
Advertising identifiers and information used for advertising and fraud prevention.
Purchase information required to verify transactions and provide premium features.
The information collected depends on the services enabled in the app and their configuration.
The app does not require users to create an account or provide bank account details to use its core calculation features.
Investment amounts and time periods entered into the calculator are used to perform calculations. We do not intentionally collect banking credentials or complete payment card details through the calculator.
We use Google Firebase services to support app analytics, diagnostics, crash reporting, and other functionality, depending on the Firebase products integrated into the app.
These services may process app usage information, device or app identifiers, crash reports, diagnostic data, and other technical information.
The information processed depends on which Firebase SDKs are enabled and how they are configured.

The app may use Google Play Billing to offer premium features, paid upgrades, or ad-free access.
When you make a purchase, Google Play processes the transaction. The app may receive purchase-related information, such as a product identifier, purchase status, transaction token, or other information needed to verify purchases and manage access to paid features.
We do not receive or store your complete payment card details through Google Play Billing.

These providers may process information according to their own privacy policies, applicable agreements, and legal obligations.

We take reasonable steps to protect information handled by the app.
Data stored locally on your device may remain there until you delete it, clear the app's storage, or uninstall the app, depending on the type of data.
Information processed by Firebase, AdMob, Google Play, or other third-party services may be retained according to their respective retention policies, settings, and legal requirements.
Although we take reasonable precautions, no method of electronic storage or transmission can be guaranteed to be completely secure.
