Sigmark
Terms of Service
Last updated: 3 May 2026

These Terms of Service ("Terms") govern your use of Sigmark ("we", "us"), a railway signalling Testing & Commissioning markup application. By signing in to Sigmark you agree to these Terms.

1. Eligibility and access

Sigmark is invitation-only. You may only use it if you have been invited by a rail operator, principal contractor, or signalling consultancy that has licensed Sigmark for one or more projects ("the Operator"). The Operator is responsible for confirming that you hold the qualifications, certifications, and authorisations required to perform the work assigned to you within Sigmark.

2. Your account

You must keep your credentials confidential and you are responsible for activity carried out under your account. If you suspect unauthorised access, contact us and your Operator immediately.

3. Acceptable use

You agree not to:

  • Use Sigmark for any unlawful purpose or to record information you know to be inaccurate.
  • Attempt to circumvent the audit trail, modify recorded events, impersonate another user, or assist anyone else to do so.
  • Stamp, sign, or attest to work that you have not personally performed or that you are not qualified to attest to.
  • Reverse engineer, decompile, or extract the source code of Sigmark, except where this right cannot be lawfully restricted.
  • Interfere with the integrity, performance, or security of the service.

4. Safety-critical disclaimer

Sigmark is a tool. You are the engineer.Sigmark records and organises the markup, attestation, and audit work you perform; it does not replace the regulatory standards, operator procedures, or competency requirements that govern signalling Testing & Commissioning. All testing, verification, and approval decisions remain your professional responsibility and the responsibility of the Operator. You must comply with the applicable rail standards (including Australian Rail Industry Safety Standards Board publications and any operator-specific procedures) when using Sigmark.

5. Project data ownership

Project data captured in Sigmark — drawings, markups, stamps, signatures, comments, audit events, and so on — is owned by the Operator that licenses Sigmark for the project. We act as a data processor on the Operator's behalf for that data. The Operator may export, retain, or delete project data subject to its own evidence-retention obligations and our service agreement with them.

6. Audit trail integrity

The Sigmark audit trail is hash-chained and append-only. Once an audit event is recorded, neither you nor we can modify or remove the entry. Where you have legitimate grounds to dispute or annotate a previously-recorded event, you may do so by adding a new audit event (e.g. a TIC reopening a sheet, a designer opening a fresh correlation round, etc.); the original entry remains in the chain.

7. Intellectual property

Sigmark and its underlying software, designs, and trade marks are proprietary. Nothing in these Terms transfers any rights in Sigmark to you. Project data you create or upload remains owned by the Operator as set out in section 5.

8. Service availability

We aim to keep Sigmark available, but we do not guarantee uninterrupted access. Maintenance, infrastructure changes, or events beyond our reasonable control may cause downtime. The audit trail is designed so that in-progress work is not lost on unexpected disconnect.

9. Termination

We or the Operator may suspend or terminate your access to Sigmark at any time, for example if your authorisation to work on a project ends, if your account is compromised, or if you breach these Terms. Termination does not delete the audit trail entries you have generated; those are retained as set out in our Privacy Policy.

10. Disclaimer of warranties

Sigmark is provided "as is" and "as available". To the maximum extent permitted by law, we disclaim all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, and non-infringement. Nothing in these Terms excludes or limits any consumer guarantees that cannot be excluded under the Australian Consumer Law.

11. Limitation of liability

To the maximum extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, or business opportunity, arising out of or in connection with your use of Sigmark. Our total aggregate liability to you under these Terms will not exceed the fees received by us for the licence under which you accessed Sigmark in the twelve months preceding the event giving rise to the claim.

12. Governing law

These Terms are governed by the laws of Victoria, Australia. The courts of Victoria have exclusive jurisdiction over any dispute arising out of or relating to them.

13. Changes to these Terms

We may revise these Terms from time to time. The "Last updated" date at the top reflects the most recent change. We will notify active users of significant changes via Sigmark or by email.
