This Privacy Policy explains how EnggTools collects, uses, and protects information when you use this website. When you create an account, EnggTools may collect information such as your name, email address, login details, paid-tool trial usage, saved calculations, notes, and other information you choose to save while using the platform. EnggTools uses this information to provide account features, save your work, improve the website, maintain security, and support features such as calculation history and technical notes. The website may use analytics tools to understand traffic, page performance, and user behavior in an aggregated way. These tools help improve the website and identify useful engineering topics and tools. If advertising is enabled, third-party advertising providers such as Google AdSense may use cookies or similar technologies to serve and measure ads. Advertising is used only where the website can remain useful, readable, and policy-compliant. EnggTools does not intentionally sell personal account data. User-specific saved calculations and notes are intended to remain private to that user unless a sharing feature is explicitly added later. Users are responsible for keeping their account credentials secure. If you believe your account has been accessed without permission, contact the website owner as soon as possible. This policy may be updated as the website develops. Continued use of EnggTools after updates means you accept the revised policy.

For Pro purchases, EnggTools stores your account identifier, payment and order references, amount, payment status and access expiry. Razorpay handles payment details; EnggTools does not store card numbers or banking credentials. Saved Pro revisions include the title and dimensional inputs you submit, linked to your account. Account authentication uses Supabase; payment records and Pro revisions use Cloudflare storage. Contact contact@enggtools.in for data access or deletion requests; transaction records may need to be retained for accounting and dispute handling. See Payments & refunds in the footer for purchase terms.

EnggTools tries to collect only the information needed to run the site features a visitor actually uses. Public article reading and calculator browsing can work without an account, while account-based features such as saved calculations and notes require login-related records so that the correct information can be shown back to the right user.

Advertising and analytics signals are treated as site-improvement and funding tools, not as a reason to make the engineering experience intrusive. Visitors should still be able to read calculator assumptions, article explanations, and standards notes clearly even when advertising technology is present.
