Privacy Policy

Harmonic Series ("we," "our," or "us") operates The Tanpura mobile application (the "App"). This Privacy Policy explains how we collect, use, and protect your information when you use our App.

1. Information We Collect

We are committed to minimizing data collection. The Tanpura collects only what is necessary to provide our services:

Purchase Information

When you make a purchase, transaction data is processed by RevenueCat, our subscription management provider. This includes purchase receipts, subscription status, and transaction identifiers. We do not store your payment card details.

Trial Usage Data

We track trial timer usage locally on your device to manage the free daily playback allowance. A minimal, anonymized request is sent to our server to activate extended trials. No personal identifiers are transmitted.

Device Information

We may collect basic device information (device type, operating system version) solely for app compatibility and crash diagnostics. This data is anonymized and cannot identify you personally.

2. Information We Do Not Collect

• —Personal names, email addresses, or phone numbers
• —Location data
• —Audio recordings or microphone data
• —Contacts, photos, or other device content
• —Advertising identifiers or tracking profiles

4. Data Storage & Security

App preferences, settings, and trial timer data are stored locally on your device using encrypted storage. We do not maintain external databases containing your personal information. Purchase data is managed securely by RevenueCat and the respective app stores.

5. Your Rights

Depending on your jurisdiction, you may have the right to:
