Privacy Policy

Last updated: August 2, 2026

1. Introduction

Welcome to Vastu Aayadi Calculator. We respect your privacy and are committed to protecting your personal data. This privacy policy will inform you about how we look after your personal data when you use our mobile application and tell you about your privacy rights.

2. Data Collection and Usage

We may collect and process the following types of data:

• Account Data: If you use Google Sign-In, we collect your basic profile information (such as name and email address) for authentication purposes using Firebase Authentication.
• Usage Data: We may collect data on how the app is accessed and used. This data may include information such as your device's Internet Protocol address (e.g., IP address), device type, and diagnostic data.
• Cloud Storage: We use Firebase Firestore to store your preferences and app data securely.

3. Third-Party Services (AdMob and Firebase)

Our app uses third-party services that may collect information used to identify you. These include:

• Google AdMob: We use Google AdMob to display advertisements in our app. AdMob may collect and use data (such as your Advertising ID and IP address) to serve personalized or non-personalized ads. You can learn more about how Google uses data for advertising here.
• Firebase Services: We use Firebase (Authentication, Firestore, Cloud Functions) to power the backend of our app. Firebase may collect analytics and usage data to help us improve the app.

4. Subscription Data

If you purchase a premium subscription, the transaction is handled entirely by Google Play Billing. We do not collect or store your sensitive payment information (like credit card numbers). We only store your subscription status (e.g., active or expired) to grant you access to premium features.

5. Data Security

We value your trust in providing us your Personal Information, thus we are striving to use commercially acceptable means of protecting it. We use Google's secure Firebase infrastructure to store and transmit your data.

6. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.

7. Data Deletion Policy

We provide users with full control over their data. If you wish to delete your account and all associated data (including saved calculations, preferences, and profile data), you can request data deletion by emailing us at support@nambu-vastu.com with the subject line "Account Deletion Request".

Upon receiving your request, we will delete all your personal data from our active databases within 30 days. Please note that active subscriptions must be cancelled separately through Google Play, as we do not manage billing data.
