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:
