Terms of Service

Last updated 6 July 2026

These terms are a legal agreement between you and Sign OS (“Sign OS”, “we”, “us”) covering your use of the Sign OS platform and related services (the “Service”). By creating an account or using the Service you agree to these terms. If you don't agree, don't use the Service.

1. Your account

You must provide accurate details and keep your login secure. You are responsible for activity under your account and for the users you invite. You must be authorised to act for the business you register.

2. The Service

Sign OS provides quoting, job management, purchasing, invoicing, an online store and related tools for sign manufacturers. We add and change features over time. Some features are described as in development or planned and may change or not ship.

3. Plans, fees and billing

Paid plans are billed in advance through our payment processor, Stripe, in Australian dollars (AUD) at the prices shown on our pricing page. A free trial, where offered, converts only if you choose a paid plan. You can change or cancel your plan at any time from your billing settings; cancellation takes effect at the end of the current billing period and fees already paid are non-refundable except where required by law, including the Australian Consumer Law.

4. Acceptable use

Don't use the Service unlawfully, infringe others' rights, upload malicious code, attempt to breach security or access other tenants' data, or resell the Service without our agreement. We may suspend accounts that put the Service or other customers at risk.

5. Your data

You own the data you put into Sign OS. You grant us the licence needed to host and process it to provide the Service. Our handling of personal information is described in our Privacy Policy. You are responsible for keeping your own records and for the accuracy of the data you enter.

6. Availability and support

We work to keep the Service available and reliable but don't guarantee uninterrupted access. We may perform maintenance and update the Service. Support is provided by email at [email protected].

7. Third-party integrations

The Service can connect to third-party services such as Xero, MYOB, QuickBooks and email providers. Your use of those services is governed by their own terms, and we aren't responsible for them.

8. Liability

To the extent permitted by law, the Service is provided “as is” and our liability for any claim is limited to the fees you paid in the three months before the claim. Nothing in these terms excludes rights you have under the Australian Consumer Law that cannot lawfully be excluded.

9. Termination

You can stop using the Service and cancel at any time. We may suspend or end access for breach of these terms or non-payment. On termination we may delete your data after a reasonable period; export what you need first.

10. Changes and governing law

We may update these terms; material changes will be notified in-app or by email. These terms are governed by the laws of Victoria, Australia, and you submit to the courts of that state.
