Privacy Policy

1. No Accounts & In-Browser Processing

All calculators on this website run entirely inside your web browser (client-side). No registration or login is required. The numbers, IP addresses, passwords, or JSON payloads you enter into any tool are never transmitted to or stored on any server.

2. Local Storage Usage

We use browser localStorage solely to remember your display preferences: your chosen interface language (Indonesian or English) and color theme (Light or Dark mode). We never store calculator inputs in localStorage or cookies.

3. Advertising Cookies & Consent Mechanism

When advertising is enabled, third-party ad partners including Google AdSense may use cookies to serve ads based on a user's prior visits to this website or other websites. For users located in the European Economic Area (EEA), the United Kingdom, and Switzerland, a Consent Management Platform (CMP) hook is provided to manage advertising consent preferences without blocking access to any calculator.

4. Engineering Disclaimer

Calculated outputs across all tools are mathematical estimates based on the stated standard formulas. Always verify results against official vendor documentation before production deployment. (Disclaimer)
