Terms of Service

Version 2026-10-02 · Last updated 2 October 2026

Opus is a documentation tool only. It does not provide medical advice, diagnosis or treatment recommendations. The treating surgeon remains solely responsible for patient care and for the official clinical record.

1. These terms

These terms are an agreement between you and Dr Mateusz Gladysz, New Zealand (“we”, “us”), the provider of Opus. By creating an account or using Opus you agree to them. If you do not agree, do not use Opus.

2. What Opus does

A personal logbook for surgical cases, with structured entry and SNOMED CT coding, stored encrypted on your phone.
Sharing a case, end-to-end encrypted, with colleagues you tag who use Opus, so they can confirm their involvement.
Operative feedback assessments exchanged between colleagues.
Exports and reports laid out for training programmes and audits.

3. Who can use Opus

Opus is intended for registered medical practitioners and doctors in training. Any professional details you add, such as registration numbers, must be your own and accurate.

4. Your responsibilities

Keep your password, PIN and devices secure.
Make sure the information you enter is accurate.
Record and share patient information only as your professional, legal and employer obligations allow — including the Health Information Privacy Code 2020 (New Zealand) or the Australian Privacy Principles, and your hospital’s policies on clinical records and photography.
Share cases only with colleagues who were part of the care team.
Keep the official clinical record in your hospital’s systems; Opus does not replace it.
Check any export or report against your programme’s current requirements before you submit it.

5. Clinical information in Opus

Codes, classifications and staging shown in Opus are derived from what you enter, to help you document consistently. They are not advice. Clinical terminologies and classifications remain the property of their owners.

6. Your data

Your data remains yours. We process it only to provide Opus, as set out in our Privacy Policy. Your logbook is stored on your phone and is not backed up by us. You can make encrypted backups yourself (Settings → Backup & Restore); keeping the backup file and its Recovery Key safe is your responsibility. A backup cannot be opened without its Recovery Key, and we cannot recover a lost key for you. If you lose the phone or delete the app without a backup or an export, the logbook is lost. Back up regularly.

7. Acceptable use

Do not impersonate anyone, add people to your team list who you do not work with, share cases with people outside the care team, attempt to access other users’ data, interfere with the service, or copy or reverse-engineer the app except as the law allows.

8. Changes and availability

We may change or discontinue features. We will tell you in the app or by email before material changes to these terms take effect. Opus may occasionally be unavailable; features that work offline keep working.

9. Liability

To the extent permitted by law, we are not liable for indirect or consequential loss, loss of data, or clinical outcomes and decisions, and Opus is provided “as is”. Nothing in these terms limits rights you have under the Consumer Guarantees Act 1993 (New Zealand), the Australian Consumer Law or any other law that cannot be excluded.

10. Ending

You can delete your account at any time in Settings. We may suspend or close an account that breaches these terms.

11. Governing law

These terms are governed by the laws of New Zealand.
