By purchasing and/or using any Kannamwar Engineering software you agree to the following terms and conditions. If you do not agree to all the terms and conditions of this agreement, then you must not use the software.
Some features use artificial intelligence (Kannamwar AI) to propose section geometry or set up models. You are responsible for what you give it and for checking everything it proposes before you rely on it; its output can be incomplete or wrong. You must not use it to create unlawful, infringing or harmful content, and we may limit or remove its use where that happens. You keep your rights in your own inputs and in the models you build from its proposals.
Results from any engineering software should always be double checked when applied in real-life applications. As a Kannamwar Engineering user, it is your responsibility to validate the output of the software with some other independent means.
Kannamwar Engineering software results can only be used for design purposes when approved by a professional and competent engineer.
You must provide your legal name, valid email address, and any other information requested to complete the registration process.
Your license is limited to a single user. The sharing of an account with more than one user is prohibited. You will experience suspensions or termination if the account is used simultaneously in multiple locations or on multiple devices per month.

Where you authorise a recurring payment, you allow the subscription's price to be charged at the start of each billing period until you cancel. For cards issued in India, you are told before each recurring charge and charges above the Reserve Bank of India limit need your approval each time, as RBI rules require.
If a renewal payment fails, we will tell you by email. If it is not paid, your account moves to Free Explorer at the end of the period already paid for.
You may cancel at any time from Settings on your account (for a Team, its owner, from Organisation → Billing), or by writing to tech@kannamwar.com.

A plan is activated once its payment is received in full. You are responsible for keeping your billing details up to date.
Free Explorer is for learning, testing and non-commercial use. Commercial use needs a paid plan.
