3.1 General obligations

You must only use the platform and the access method for your own lawful internal business purposes and in accordance with this agreement. You must never use the platform and the access method for the creation of publicly accessible tools and applications.

You acknowledge that the platform is continuously evolving, subject to ongoing development and improvement, and may not be suitable for all uses. The platform must not be used for any purposes on which critical infrastructure or human life depends, or in circumstances where any failure or malfunction may result in personal injury.

In most circumstances, you are solely responsible for the interoperability of the platform with your computer systems, software and hardware. We accept no responsibility for any liability in connection with the manner in which the platform interoperates (or fails to interoperate) with your, or any third party, systems, software or hardware.

In the case of a subscription to an enterprise plan, which includes the incorporation of software customization and professional services, specifications on interoperability will be covered under a separate agreement.

3.2 Access conditions

You must ensure that all credentials required to access the platform are kept secure and confidential. You must immediately notify us of any unauthorized use of your credentials or any other breach of security and you must take all other actions that we reasonably deem necessary to maintain or enhance the security of our computing systems and networks and your access to the platform.

When accessing and using the platform, you must:

(a) not attempt to undermine the security or integrity of our computing systems or networks or, where the platform is hosted by a third party, that third party's computing systems and networks;

(b) not use, or misuse, the platform in any way which may impair the functionality of the platform or the access method, or other systems used to deliver the platform or impair the ability of any other user to use the platform or the access method;

(c) not attempt to gain unauthorized access to any data, information or materials (other than those to which you have been given express permission to access) or to the computer systems on which the platform is hosted;

(d) not transmit via, or input into, the platform any files that may damage any computing devices or software, content that may be offensive, or material or data in violation of any law (including data or other material protected by copyright or trade secrets which you do not have the right to use); and

(e) not attempt to modify, copy, adapt, reproduce, disassemble, decompile or reverse engineer any computer programs or algorithms forming part of, or used to deliver, the platform or the access method.

3.3 Communication conditions

If you use any communication tools available through the access method (such as email, chat or forums), you must agree only to use such communication tools for lawful and legitimate purposes. You must not use any such communication tool for posting or disseminating any material unrelated to the use of the platform, including: offers of goods or services for sale, unsolicited commercial email, files that may harm any other person's computing devices or software, content that may be offensive or in violation of any law (including material that is protected by copyright or trade secrets which you do not have the right to use).

When you make any communication via the access method, you represent that you are permitted to make such communication. We are under no obligation to ensure that any communications are legitimate or that relate only to the use of the platform. As with any other software, you must exercise caution when using communication tools available via, or relating to, the platform. However, we reserve the right to remove any communication at any time in our sole discretion.

4. Payment

4.1 Fee

Unless you are accessing a trial or free version of the platform, an invoice for the fee will be issued either annually or each month starting one month (the "billing period") from the date you first agreed to the terms of this agreement. All invoices will include the fee for the following billing period. We will continue invoicing you according to the agreed schedule until this agreement is terminated in accordance with clause 8.

The fee may be varied by us no more than once every 12 months. We will give you at least 30 days' notice of any changes. If you do not accept any increase in the fee then you may terminate this agreement or elect to change to a different plan within such notice period.

If you elect to upgrade to a plan with additional features, your fee will increase to our then current list price for such plan, unless we have agreed to give you access at a different price. You may elect to downgrade to a plan with fewer features, however, no refund will be given for any fee previously paid or payable. The fee for the subsequent billing period will decrease to our then current list price for such plan, unless we have agreed to give you access at a different price.

4.2 Invoicing and payment

All invoices will be sent to your nominated email address. You must pay all amounts specified in any invoice by the due date on the invoice. If you have set up auto-billing arrangements with us then we will deduct the payment automatically under the terms of those arrangements. You must ensure that you have adequate funds in your nominated bank account or a valid credit card to enable all automatic payments to be processed when due.

If invoices are not paid in full by the due date (including due to any failure of an automatic payment) then, in addition to any other rights we have, we may:

(a) suspend your access to the platform immediately and without further notice, and

(b) charge you interest on the overdue amount at the United States Federal Reserve Federal Funds Rate plus four per cent (4%) per annum, calculated from the date the payment became due to the date of full and final payment.

4.3 Taxes

Unless expressly stated otherwise, all amounts stated to be payable in this agreement (or related documents such as quotations or invoices) exclude Goods and Services Tax ("GST").

If GST is imposed on any supply made under, or in accordance with, this agreement, the recipient of the taxable supply must pay an additional amount equal to the GST payable on or for the taxable supply. Payment of the additional amount will be made at the same time as payment of the taxable supply is required to be made in accordance with this agreement.

If this document requires a party to pay for, reimburse or contribute to any expense, loss, indemnity or outgoing (reimbursable expense) suffered or incurred by another party, the amount required to be paid, reimbursed or contributed by the first party will be the sum of:

(a) the amount of the reimbursable expense less the input tax credits (if any) to which the other party is entitled in respect of the reimbursable expense; and

(b) if the other party's recovery from the first party is a taxable supply, any GST payable in respect of that supply.

In this clause, "GST" and other words defined in the "A New Tax System (Goods and Services Tax) Act 1999 (Cth)"  or subordinate legislation have the meaning given in that legislation.

If we are required to charge you value added, goods and services or similar taxes and duties under the laws of any other jurisdiction, you must pay all such additional amounts at the same time as payment of the taxable supply is required to be made.
