How It Works

Subscribing to and accessing our website and resources

Access to Sigma Science’s members section is provided to you as a subscriber upon our receipt of appropriate payment and purchase order form. An email will be sent to you providing you with logon details. We will also send you a receipt in confirmation of your payment. Subscribing to Sigma Science members section allows you access to the website for 12 or 24 calendar months depending on your choice of subscription. If you wish to continue to access Sigma Science members section after your selected subscription period is due to expire, you will need to renew your subscription with your required package and subscription period (see pricing plan) before your current subscription is due to expire. If you fail to renew your annual subscription, we will place your account on ‘pending’ and may deny you access to the members section of Sigma Science. We will not give you advance formal notice and warning of this action. We will send a reminder notice to you via email approximately one month before your subscription period is due to expire. Refunds will be given at our discretion.

Access to our preview resources is free and open to all users. Access to our members section is by unique username and password which are supplied to you when you subscribe. You must not disclose your username or password to any third party. You must take reasonable precautions to prevent any third party from accessing your username and password. If you disclose your username and password to a third party, your access may be terminated.
