PAYMENT & ACCESS
A clear record of your purchase.
EnggTools Pro is 30-day digital access to the paid calculators, tolerance modules, complete standards guides, and comparison workspace described on the Plans page.
Payment support and refunds
For duplicate charges, payment without access, or a service problem, email contact@enggtools.in with your payment reference and account email. Requests are reviewed individually; approved refunds return through Razorpay to the original payment method. Bank processing times vary. Statutory consumer rights are unaffected.
What the pass includes
Pro includes continued B31.3 and bolt torque calculations, all ten tolerance stackup modules, complete standards guides, two-alternative tolerance comparisons, up to 100 stored revisions, and printable reports. Personal engineering approval and consultancy are separate services.
Trials and expiry
Signed-in users receive two completed calculations per paid calculator or individual tolerance module. Invalid input does not use a trial. Trial allowances are lifetime allowances and do not reset when Pro expires. Saved comparison revisions remain readable after expiry.
Data and payment records
Razorpay handles payment entry. EnggTools stores your account identifier, order and payment references, amount, payment status, access expiry, and trial usage. EnggTools does not store your card number, CVV, or UPI PIN.
