1. About these terms

1.1 These terms apply to DuctSheet (we, us).

1.2 By creating an account or using DuctSheet, you agree to these terms. If you use DuctSheet for a business, you agree on behalf of that business.

1.3 We may update these terms. We will give you at least 14 days' notice by email or in the app. If you keep using DuctSheet after that, the new terms apply.

2. Accounts and subscription

2.1 You must give accurate details and keep your login secure. Each account is for one named user, may not be shared and can be active on one phone at a time. A team plan covers the number of named users stated in that plan, and each user has their own account.

2.2 New users can try DuctSheet free for 7 days. Prices are in Australian dollars and are shown before you pay. Subscriptions are billed in advance through Stripe and renew automatically until you cancel.

2.3 You can cancel at any time from your account in the app, or by emailing us. Access continues until the end of the paid period. Except as required by law, payments are not refundable.

2.4 We may change prices with at least 30 days' notice. The new price applies from your next billing period.

3. Your licence to use DuctSheet

3.1 While your subscription or trial is active, we grant you a non-exclusive, non-transferable, revocable licence to use DuctSheet for your own work measuring and documenting ductwork.

3.2 You must not, and must not allow anyone else to:

• copy, download, scrape or reproduce any part of DuctSheet, including its code, screens, layouts or calculations;

4. Intellectual property

4.1 DuctSheet, including its software, design, text, graphics, name and logo, is owned by us and protected by Australian and international copyright and trade mark laws. © 2026 DuctSheet. All rights reserved.

4.2 Apart from the licence in clause 3, nothing in these terms gives you any rights in DuctSheet.

6. Australian Consumer Law

Nothing in these terms excludes, restricts or modifies any right or remedy you have under the Australian Consumer Law that cannot lawfully be excluded. Where our liability for a breach of a consumer guarantee can be limited, it is limited to supplying the service again or paying the cost of having it supplied again.

7. Disclaimer and liability
