Privacy Policy

1. Privacy-First Client Calculation

At MerchSites, we respect your commercial confidentiality. All financial calculations, numbers, margins, product costs, and pricing inputs entered into our calculator tools are processed 100% locally inside your web browser. Your confidential business calculations are never transmitted to our servers or stored in any database.

2. Anonymous Analytics & Usage Data

We use Google Analytics (GA4) to collect aggregated, non-personally identifiable website traffic data, such as page views, browser types, and referring websites. This helps us understand which financial calculators are most useful and optimize site performance.

3. Advertising & Affiliate Disclosures

MerchSites may display contextual advertisements or affiliate recommendations for ecommerce software and services. If you choose to sign up through an affiliate link, MerchSites may receive a small referral commission at no additional cost to you.

4. Local Storage Usage

Some calculator tools utilize your browser's localStorage feature to remember recent input preferences across page refreshes for your convenience. This data remains on your personal device and can be cleared at any time through browser settings.
