Terms of use

1. Using the service

Twiggy Modeller lets you model business processes, interview subject-matter experts with AI assistance, and send models for review and sign-off. By signing in or using a sign-off link you agree to these terms. If you use it for an organisation, you confirm you are allowed to accept them on its behalf.

2. Your account

You sign in with a link sent to your email address. Keep access to that mailbox secure; anyone who can open your sign-in links can use your account. People you invite to your workspace, and people you send sign-off links to, can see the models you share with them.

3. Your content

• You keep all rights in the models, notes, interviews and comments you add ("your content").
• You give us permission to store, process and display your content only to provide the service to you and the people you share it with, including sending it to our AI provider when you use AI features.
• You are responsible for having the right to add your content, and for not adding information you are not allowed to share (for example, personal data without a lawful basis, or confidential third-party material).

4. AI features

AI suggestions (interview questions, model changes, boundary events, link matches) can be wrong or incomplete. Review them before relying on them; models are yours to check and sign off.

5. Acceptable use

Don't misuse the service: no attempts to break or overload it, access other workspaces, get around its limits, or use it for anything unlawful.

6. Plans, seats and payment

• Paid plans are billed monthly in advance through our payment provider, in Australian dollars including GST. Prices and what each plan includes are on the pricing page.
• On the Team plan you pay for modeller seats: one for each person who builds or changes models (modellers, admins and the owner), within the plan's range. Approvers, reviewers and viewers don't need a seat; each seat includes a number of them, and anyone can sign off from an emailed link without joining.
• Your admins choose how many seats to pay for under Admin › Plan › Seats, and whether a seat is added automatically when someone is made a modeller. Adding or removing seats is prorated on your next invoice. You can't pay for fewer seats than the people holding one.
• Each plan includes a monthly AI allowance (on Team, an amount for each seat). Unused allowance doesn't carry over. AI top-ups you buy are used after the allowance and last 12 months. Allowances are measured in units of AI use, not in models or conversations.
• Corporate seats, reader places, AI and pricing are as agreed with you in writing.
• We may change prices, allowances or what a plan includes. We'll tell your workspace's owner by email at least 30 days before a change takes effect for you; you can change plan or cancel before then. A change that only adds to a plan can take effect straight away.
• You can cancel at any time: the plan stays until the end of the period you've paid for, then the workspace moves to Free and your models stay. We don't refund part periods, except where the law requires it.

7. Availability and changes

We work to keep the service available and your content safe, but don't guarantee it will be uninterrupted or error-free. We may change or improve features over time. Keep your own copies of important models (you can download any model as a .pml file).

8. Ending use

You can stop using the service and delete your models at any time. We may suspend access that breaks these terms or puts the service or others at risk.

9. Liability

To the extent the law allows, the service is provided "as is", and we are not liable for indirect or consequential losses, or for losses caused by relying on AI output or on content added by others. Nothing in these terms limits liability that cannot be limited by law.

10. Changes to these terms

We may update these terms and will change the date above when we do. Continuing to use the service after a change means you accept the updated terms.
