Last updated: February 18, 2026
EHM Tech LLC ("we", "us", or "our") operates the Tax47 (Tax Calculator USA) mobile application (the "App"). This Privacy Policy informs you of our policies regarding the collection, use, and disclosure of information when you use our App.
By using the App, you agree to the collection and use of information in accordance with this policy.
You can review the most current version of this Privacy Policy at https://tax47.app/privacy/.
1. Privacy-First Design
Tax47 is designed with your privacy as the top priority. All tax calculations are performed entirely on your device. Your financial data, income information, and calculation results are never transmitted to our servers or any third party.
We do not collect, store, or have access to any of your tax-related information, including but not limited to: income amounts, filing status, dependents, deductions, or calculated tax amounts.
2. Information We Collect
While your tax data remains private on your device, we collect limited technical data to operate the App:
- Anonymous usage analytics (via Firebase Analytics) to understand how features are used
- Crash reports (via Firebase Crashlytics) to identify and fix app stability issues
- Purchase data for subscription management (via RevenueCat)
- Device identifiers for fraud prevention and entitlement validation (via RevenueCat)
This data helps us improve app stability and user experience. It does not include your tax calculations, income amounts, or any financial data you enter.
For more information about how Firebase handles data, see Firebase's Privacy Policy and Google's Privacy Policy.
3. No Advertising
Tax47 does not display any advertisements. We do not use advertising SDKs, and we do not collect or share data with advertisers. Your experience is ad-free.
4. In-App Purchases
Payment Processing: If you purchase the Pro version, your payment is processed by Apple (App Store) or Google (Play Store). We do not collect or store your payment information.
