Privacy notice

Last updated: 25 October 2026. This notice follows India's Digital Personal Data Protection Act, 2023.

What is collected

No accounts, no sign-up, no cookies for visitors, no advertising. To see which lessons help, the site counts page views and finished sheets, stored only as totals per day, page, country, referring website and device type (phone, tablet or desktop). No IP address, name, email, cookie or device identifier is stored, so these counts are not personal data about you.

If your browser sends Do Not Track or Global Privacy Control, nothing is counted.

What stays on your device

Your lesson progress (ticked steps, answers, quiz) is saved only in your own browser (local storage). It never reaches us. Clear your browser's site data to remove it.

Services used

The site is hosted on Cloudflare Pages; the counts are kept in Cloudflare. Fonts load from Google Fonts and the 3D viewer's library from jsDelivr; those services receive your IP address when your browser fetches the files, under their own privacy policies. Embedded videos load from YouTube's privacy-enhanced (no-cookie) domain.

Your rights and grievances

For any question, request or grievance about data, write to the grievance contact: Ahmad Khan, sheetmetal.solidcraft@gmail.com. We reply within 30 days.
