Privacy Policy
Transparent information regarding how data, offline storage, and user inputs are handled on Nepal Engineering Toolbox.
Last updated: August 14, 2026
At Nepal Engineering Toolbox (accessible from nepalengineeringtoolbox.com), the privacy of our engineers, contractors, students, and homeowners is of paramount importance. This Privacy Policy document outlines the types of information collected and recorded by us and how we use it.
1. Local Calculation & Data Privacy
All engineering calculators (such as Quantity, Steel Weight, Footing Design, Concrete Mix Design, and Area Converters) operate entirely client-side inside your web browser. When you input dimensions, building heights, or bay counts, those numbers are processed locally on your device. We do not store or track your proprietary project calculation inputs on any external database.
2. Offline PWA Caching & Local Storage
Our website functions as a Progressive Web App (PWA), allowing you to install it on your Android, iOS, or desktop device for offline use. To enable this, our Service Worker caches static assets (HTML, CSS, JS, and logos) locally on your device storage. This data is managed completely by your browser and contains no personal identifiers.
3. Email Subscriptions & Contact Submissions
If you voluntarily subscribe to our market rate alerts or submit feedback/feature requests through our contact forms, we securely store your email address and message contents in a restricted Google Spreadsheet database via our backend Apps Script.
- We never sell, rent, or trade your email address to third-party marketers.
- Your email is used strictly to send construction material price updates or respond to your inquiries.
4. Cookies and Analytics
We do not use invasive tracking cookies. However, as we expand, we may implement standard third-party analytics (like Google Analytics) or advertising networks (like Google AdSense) to help sustain the free operation of this platform. These third-party vendors may use cookies to serve ads based on prior visits to our website.
5. Consent & Updates
By using our website, you hereby consent to our Privacy Policy and agree to its terms. This policy may be updated periodically to reflect changes in engineering standards or digital regulations in Nepal.
6. Contact Information
