Cookies & Local Storage Policy
Last Updated: August 2026
1. What Are Cookies and Local Storage?
Cookies and browser local storage (localStorage) are standard technologies used by websites to store small amounts of data directly on your device. They enable web applications to function reliably, preserve your preferences, and maintain seamless sessions across page visits.
2. How We Use Storage on MWh in kWh
MWh in kWh is built on a privacy-first, client-side architecture. We do not use tracking cookies, behavioral advertising beacons, or third-party marketing identifiers. All energy calculations (Megawatt-hours to Kilowatt-hours) are processed entirely inside your browser and are never transmitted to external servers.
3. Types of Storage Technologies Used
• Essential Functional Storage:
Stores your UI theme selection (Dark Mode or Light Mode) and your cookie consent preference so you are not prompted repeatedly on return visits.
• Calculator State & Efficiency:
Temporarily retains your active conversion unit selections locally to prevent data loss while navigating between conversion tools.
• Privacy-Preserving Performance:
Aggregated static asset caching to ensure lightning-fast page loading across our 18 international localized editions without profiling individual users.
4. Managing and Clearing Your Cookies
You can control, block, or delete cookies and local storage directly through your web browser's privacy and security settings. Disabling storage will not impair our core calculation tools, though your theme preferences will reset upon refreshing.
5. Regulatory Compliance & Updates
Our data practices strictly comply with international data privacy regulations including the GDPR (General Data Protection Regulation), ePrivacy Directive, and CCPA. We may periodically update this policy; revisions will be posted here with an updated date.
