Real Estate Lead Metrics Privacy Policy

Effective Date: August 27, 2026Last Updated: August 27, 2026
Privacy Guarantee Summary

Real Estate Lead Metrics does not collect or transmit user-entered calculation data.
Values entered into the calculator are processed locally in your browser memory during calculation.
No calculation data is transmitted to Koray Yalçın or any third party.

1. Local In-Browser Processing (Yerel İstemci Hesaplaması)

Real Estate Lead Metrics is designed as a zero-telemetry, client-side utility calculator for Google Chrome. When you enter values such as Advertising Spend, Total Leads, Contacted Leads, Appointments, Sales, or Revenue into the calculator fields:

  • All mathematical formulas are executed locally within your browser's active memory (RAM).
  • Input and output values exist only during your active popup session and are instantly discarded when the extension popup is closed.
  • No entered financial, lead count, or marketing performance data is saved, written to disk, or transmitted across network connections.

2. Data Collection and Data Access (Veri İzinleri ve Erişim)

In full alignment with Google Chrome Web Store Developer Program Policies and Privacy Guidelines, the extension operates with the following explicit data access parameters:

3. Third-Party Sharing

Because Real Estate Lead Metrics does not collect, store, or transmit any user data,no data is ever sold, rented, shared, or transferred to third parties, advertising networks, data brokers, or external servers under any circumstances.

4. Chrome Permissions Transparency

"permissions": []

This guarantees by design that Chrome enforces sandbox boundaries preventing the extension from requesting elevated privileges or monitoring background network activity.
