In short: NVDRA Calculator is free. There are no plans, subscriptions or payments, so there is nothing to cancel or refund.
A free service
Every calculator is free to use, without registration. We will never ask you to pay to see a result.
Beware of anyone asking for money
NVDRA will not contact you to ask for a payment for NVDRA Calculator. If anyone asks you to pay for it, or offers a “premium” version in our name, do not pay and report it to support@nvdra.com.
If paid features are added
If we ever offer optional paid features, their prices, billing and refund terms will be published here before anyone is charged. Other NVDRA applications have their own refund policies on their own websites.
