Terms of Service

Our Terms of Service are pretty simple and straightforward:

1. All “Free” or “Sample” calculators and kits are free to be used as you please. You can copy, share, gift, distribute and do whatever you like with them.

2. All “Premium” or “Full Version” calculators and kits are for private use only. You are not allowed to share, copy (except for your own backup or archiving purposes), distribute, sell, re-sell, rent, gift or give them away by any other means.
