Terms of use

The terms Certlyn is provided on.

Last updated 24 October 2026. Certlyn is provided by Certlyn Technologies Pty Ltd (ABN 29 702 866 957) (“we”, “us”). These terms apply to every firm that uses Certlyn and to every person who signs in, including a firm’s clients using the portal. By using the service you agree to them. Fees and the length of a firm’s subscription are set out in the written agreement between Certlyn Technologies Pty Ltd and the firm, which sits alongside these terms.

1. What Certlyn is, and what it is not

Certlyn is software for recording and managing building certification work. It is not a certifier and does not provide certification, building, planning or legal advice.

Every statutory decision — what a project requires, whether a document is acceptable, whether a certificate should be issued, what an inspection found, what is reported to the NSW Planning Portal — is made by the registered certifier using the service, who remains responsible for it under the Environmental Planning and Assessment Act 1979 and the Building and Development Certifiers Act 2018. Certlyn assists with the recording and paperwork; it does not and cannot take over that responsibility.

2. Accounts

  • A firm is responsible for the people it gives access to, for keeping passwords private, and for telling us promptly if an account may have been compromised.
  • Each login is for one person. Certifiers must not share a login; a certifier's signature is applied only by that certifier.
  • A firm's clients are given portal access by the firm, and see only the projects that firm has shared with them.

3. Your data

  • Everything a firm records in Certlyn — projects, documents, certificates, reports, client details — belongs to the firm. We claim no rights over it.
  • We hold it on the firm's behalf and use it only to provide the service, as described in our privacy policy.
  • We open a firm's projects through our hosting platform only when the firm asks us to, for example to provide support. We do not issue, sign, send, alter or delete anything on a firm's behalf.
  • Records a certifier is legally required to keep remain the firm's responsibility to retain. What happens to access when a firm's agreement ends is set out in section 10.

4. Acceptable use

You must not use Certlyn to:

  • record anything you know to be false, or issue any document you are not entitled to issue;
  • access, or attempt to access, another firm's data;
  • upload material that infringes someone else's rights or is unlawful;
  • interfere with the service, probe its security, or place unreasonable load on it;
  • copy, reproduce, imitate or adapt Certlyn or any part of it — its software, screens, design, workflows, templates, layouts, wording, checklists or documentation — in any form. The certificates, reports and other documents Certlyn produces for a firm's own projects may be issued, used and kept by that firm in its certification business.

5. AI features

Where a firm switches them on, some features use an AI model to write notes. Its output is a suggestion: it is shown for a person to check, and nothing it produces is issued, sent or saved without that person acting. The firm is responsible for reviewing anything it accepts. AI features may be unavailable from time to time and may be changed or withdrawn.

6. Third-party services

Certlyn relies on providers for hosting, email, card payments, AI and cloud backup, and on the NSW Planning Portal. We choose them with care, but we do not control them and cannot guarantee their availability or conduct. Card payments are subject to Stripe’s terms; cloud backups go to accounts the firm controls under those providers’ terms.

7. Availability and support

We aim to keep Certlyn available at all times but do not guarantee uninterrupted service. We may take it offline for maintenance, with notice where practicable. Support is provided to firms by email during business hours in New South Wales. We look at a firm’s own projects only when the firm asks us to, as described in section 3.

8. Fees and payment

Fees are as agreed in writing with the firm in its subscription agreement. We may increase fees at any time by giving at least thirty days’ written notice; the increase applies from the next billing period after the notice period ends.

Billing runs by the calendar month. A firm joining part-way through a month is charged for that whole month, and the projects it covers are counted from the first of that month. An invoice is issued after the end of each month and is due seven days after the end of the month it is for. Payment is by bank transfer or direct debit only; no other method is accepted.

A subscription covers a number of new projects each calendar month, with a per-project charge past that. One project means one job: a Complying Development Certificate and a separate Construction Certificate on the same site are two projects, an Occupation Certificate engagement is one, and a modification within an existing job is not a new project.

  • A project that has been deleted is not counted.
  • A project brought across from another system when a firm joins is not counted, until the date agreed with that firm.
  • The count for the current month is always visible to the firm under Settings.

9. Unpaid fees

If an amount is unpaid fourteen days after its due date, we may suspend the firm’s access to Certlyn, in whole or in part, without further notice, until everything overdue is paid. Fees continue to accrue during a suspension. Paying the outstanding amount lifts the suspension.

10. Ending the agreement, and records access

  • A firm may end its subscription by written notice, effective at the end of the calendar month in which it is given.
  • We may end a firm's subscription at any time, for any reason, with immediate effect, by written notice.
  • When a firm's agreement ends, its access to Certlyn, including to its records, ends.
  • A firm may keep read-only access to its records after its agreement ends by paying for records access: $1,200 plus GST a year, paid in advance. Records access lets the firm sign in, view and download its records only: it cannot create projects, issue approvals, record or report inspections, upload documents or change anything. Without it, no access is given, and we may delete the firm's data except where the law requires us to keep it.
  • A firm alone remains responsible for keeping the records it is legally required to keep, including by downloading them before its agreement ends or by holding records access.

11. Liability

To the maximum extent permitted by law, our total liability for all claims arising out of or in connection with Certlyn or these terms, however caused, including by negligence, is limited to the monthly fee (excluding GST) the firm paid for the one month before the event giving rise to the first claim, and we are not liable for any indirect or consequential loss. In particular, because every certification decision is the certifier’s, we are not liable for the consequences of a certificate, report or notice a certifier issues, or fails to issue, using the service.

Nothing in these terms excludes rights under the Australian Consumer Law that cannot be excluded. Where our liability for a failure to comply with a consumer guarantee can be limited, it is limited to supplying the services again or paying the cost of having them supplied again.

12. Changes to these terms

We may update these terms, our privacy policy and the subscription agreement at any time. Updated terms take effect when they are published here or sent to a firm by email, whichever is earlier. Continued use of Certlyn after that is acceptance of them; a firm that does not accept them may end its subscription under section 10.

13. Governing law

These terms are governed by the law of New South Wales, Australia, and its courts have jurisdiction over any dispute.
