It works on a monthly basis, starting and ending the day of the month you signed up. For example, if you sign up for a standard account today, you will be charged 40 USD in your credit card today and every 28th day of the month. If you decide to cancel your subscription, you will no longer be charged the next month and your account will still be good until the end of the billing cycle.
Data regarding your credit card (holder name, number, CVC, expiration, etc.) gets to our servers encrypted through a secure connection. Just make sure there is a green lock in the location bar of your browser:
We then send such data, again encrypted through a secure connection, to a PCI-compliant payment-processing provider that handles your information appropriately. We do not store your information in our servers. We use the tokenization technique, which is the common mechanism for handling financial information in monthly subscriptions. So the answer is that the payment mechanism is state-of-the-art-secure.
When you sign up to CAEplex you start with a Free account. Whenever you want to evaluate how CAEplex works with your 3D CAD models, you can start a 14-day trial period. During this period, you might upload your own geometries and you have 5,000 credits and 256 Mb of data storage. After 14 days, your account will go back to the Free subscription automatically. At any time (either before or after the trial expires) you can upgrade your plan to the Standard Subscription, where you enter your credit card information once and start a billing cycle as explained above. You can only use your trial period once. After your account is downgraded back to the Free subscription, you can only then either subscribe to the either the Lite or Standard Plan, or request an Enterprise plan.
Whenever you use one of the codes that run on the cloud (i.e. to generate o mesh, to run a computation or to generate a report) one or more credits may be consumed from your account. Credits are worth both CPU time and RAM usage:
|1 second of CPU time||1 credit|
|1 Gb of RAM during 1 CPU second||1 credit|
Say you ran a computation that needed one second of CPU time and during that time it needed one Gigabyte of RAM. Then you would consume two credits. As simple as that. CPU times include both user and kernel-space times, and are really CPU time and not wall time. If a task is not successful (for example a failed meshing process) credits will not be consumed from your account.
In the Free plan, your credits are renewed every thirty days. That is to say, thirty days after you first signed up you get again 500 credits in your Free account. In the non-free plans, the first day of the billing cycle (i.e. every 28th day of the month if you started your subscription today) your credits are reset to either 2,500 or 10,000 available credits, depending on the plan. Any credits you did not use in the previous cycle are lost and are not available anymore.
