Privacy Policy

Last Updated: April 03, 2026

2. Data Collection and Usage

Our application is designed to function largely offline and process financial calculations locally on your device. However, to provide the service securely, offer premium unlocks, and run advertisements, we use selected third-party services.

A. Data Stored Locally

• App Preferences: Your selected themes (dark/light) and chosen language are stored locally on your device using Shared Preferences.
• Calculations & Inputs: Yield, options, and strategy inputs are executed on your device and are not uploaded, kept, or processed on our servers.

B. Advertising Data (Google AdMob)

We use Google AdMob to provide free access to this application. AdMob may automatically collect certain device information, such as:

• Advertising Identifiers (e.g., Google Ad ID, Apple IDFA).
• Device Information (IP address, operating system, network type).
• Usage Data (ad interactions and application launch metrics).

C. In-App Purchases (RevenueCat)

To manage "PRO" subscriptions and in-app purchases safely, we integrate RevenueCat. RevenueCat collects:

• Anonymous App User IDs generated upon installation.
• Purchase and subscription history.

Note: All payment processing is handled natively by the Google Play Store and Apple App Store. We do not have access to, nor do we store, your credit card details or billing information.

3. Third-Party Services Links

The Application uses the following third-party services. We highly recommend reviewing their privacy policies:

• Google Play Services & AdMob
• Apple App Store (iOS Only)
• RevenueCat

4. European Union Privacy Compliance (GDPR)

If you are a resident of the European Economic Area (EEA) or the UK, you are protected by the GDPR. Our App specifically implements Google's User Messaging Platform (UMP) to obtain your explicit consent securely before showing personalized advertisements.

• Your Rights: You have the right to access, rectify, or delete your personal data. You have the right to object to processing and to data portability.
• Withdrawal of Consent: You can manage and revoke your advertising consent at any time from the app's 'Privacy Preferences' icon in the settings menu.

5. US State Privacy Compliance (CCPA / CalOPPA / CPRA)

If you are a resident of California or other applicable U.S. states, you are granted specific rights regarding your personal information.

• Do Not Sell or Share My Info: We do not sell your personal data. We 'share' data strictly with our advertising partner (Google AdMob) to deliver personalized ads. You can opt-out of personalized advertising at any time through your device’s system settings (e.g., "Opt out of Ads Personalization" on Android or "Limit Ad Tracking" on iOS).
• Right to Know & Delete: You can request information about exactly what ad/purchase data has been collected, or request deletion of such ID footprints by reaching out to our contact email.

6. Children’s Privacy (COPPA)

Our Application serves as a financial and yield calculation tool and is not intended for children under the age of 13 (or 16 in certain EU jurisdictions). We do not knowingly collect personal identifiable information from children. If we discover that a child has provided us with personal information, we will immediately delete it from our integrated systems. If you are a parent or guardian and become aware of such an issue, please contact us.

7. Data Security

We value your trust. Your inputs remain fully offline. For operations that require internet access (like Ads and Purchases), we rely on robust industry leaders (Google & RevenueCat) that employ top-tier encryption and security protocols over HTTPS connections.

8. Changes to This Privacy Policy

We may update our Privacy Policy periodically to reflect new legal requirements or application features. We will notify you of any changes by updating the "Last Updated" date at the top of this policy and by prompting you via the Google UMP consent form in the app when legally required.
