### 2. Device Local Storage
* The App utilizes your device’s local storage (such as `localStorage`) solely to store:
1. Your saved financial plans and calculations (so you can view them later).
2. Your premium subscription activation status and validity.
3. Cached standard currency exchange rates.
* This data remains on your physical device at all times and is deleted if you clear the App’s data or uninstall the App.

### 3. Third-Party Services
For operations, the App integrates with the following third-party service providers:
* **Google AdMob (Ad Services)**:
The free version of the App displays advertisements served by Google AdMob. AdMob may collect and use advertising identifiers (like Google Advertising ID) and cookies to serve personalized or non-personalized ads. You can manage your ad personalization preferences in your Android device's Google settings.
* **Razorpay (Secure Payments)**:
If you choose to purchase one of our premium plans (Monthly, Yearly, or Lifetime subscription), the payment transaction is securely processed by Razorpay. We do **not** collect or store your credit card numbers, bank details, or UPI credentials. On successful payment, the App only stores your Razorpay Payment ID locally to verify your Pro features access.
