Pronoisseur — Terms of Use (Steam edition)

Last updated: 2026-11-04 · Revision 3

Pronoisseur (“the Software”) is made by NMM Software Limited (New Zealand company number 9438348, NZBN 9429053756824) (“we”, “us”). These Terms of Use are the licence agreement between you and us for the edition of the Software you get from Steam. They are written in plain language on purpose. They are not legal advice to you. Your purchase from Valve is governed by the Steam Subscriber Agreement.

By clicking “Agree & Continue”, or by installing or using the Software, you accept these terms. If you do not accept them, do not use the Software.

1. What you are getting

We grant you a personal, non-exclusive, non-transferable licence to install and use the Software on Windows devices signed in to the Steam account that owns it, within the rules Steam applies (section 4). The Software is licensed, not sold. We and our licensors keep all rights in the Software that these terms do not expressly give you.

2. Plans and refunds

You get the Software from Steam. In summary:

  • No free trial. There is no free trial in the Steam edition. Steam’s refund policy lets you request a refund within 14 days of purchase if you have used the Software for less than 2 hours (store.steampowered.com/steam_refunds).
  • Perpetual licence. You pay once through Steam. The licence does not expire, and it includes every update we release for this major version of the Software — there is no update window to run out. A future major version sold as a separate product is not an update.
  • There are no subscriptions in the Steam edition.

Features we label “beta” or “experimental” may change or be removed.

3. Buying, billing and refunds

  • You buy the Software from Valve Corporation (“Valve”) through Steam. Valve sells and distributes the Software: the Steam Subscriber Agreement applies to the purchase, and Valve shows the price in your currency, issues your receipt, handles payment, and collects tax. We do not receive your card details or billing address.
  • Refunds follow the Steam Refund Policy. Request one through Steam Support (help.steampowered.com). We cannot issue a Steam refund ourselves, but email [email protected] if you are stuck and we will point you the right way.
  • If Valve refunds or reverses the payment, the licence that payment bought ends.
  • Nothing in this section limits refund or other rights you have under the law where you live (see section 10).

4. Your licence, devices and offline use

  • Your licence is held by your Steam account. There is no licence key to enter or keep, and the Software sends us nothing to check it: the Software confirms ownership with the Steam client on your PC. Launch the Software from Steam.
  • Devices. Install the Software on the Windows devices where you sign in to your Steam account, under Steam’s rules. Steam Family Sharing follows Steam’s rules, not ours.
  • Checking ownership. If Steam cannot confirm the licence, the Software shows a screen asking you to launch it from Steam, where you can check again, open Steam or quit.
  • Offline use. Steam’s Offline Mode keeps the licence check working without an internet connection. If Steam cannot confirm the licence, the “Launch Pronoisseur from Steam” screen appears.
  • Do not copy the Software out of its Steam installation, or bypass the licence check.

5. Updates

Updates are delivered by Steam according to your Steam settings. Updates may add, change or remove features, and a future version may need a newer version of Windows. We do not promise any particular future feature or a release schedule.

6. Your content and your setup

The Software organises and plays media files that you supply. You are responsible for the files you add and for having the right to use them. We never see, receive or copy your media, your library or your file names.

If you connect other programs to the Software through its Local API (Settings → Connected apps), you are responsible for those programs and for the tokens you issue to them. The API only listens on your own computer.

7. What you may not do

You may not:

  • copy, redistribute, rent, lease, lend, sell or sublicense the Software;
  • reverse-engineer, decompile or disassemble the Software, except to the extent the law where you live allows this despite this restriction;
  • remove or change any proprietary notice in the Software;
  • bypass, disable or interfere with the Software’s licensing or update mechanism, or help anyone else to;
  • use the Software in breach of any law that applies to you, or in a country or by a person subject to New Zealand or other applicable sanctions or export restrictions that prohibit it.

8. Third-party software and services

  • The Software includes open-source components under their own licences. Their notices and licence texts are in the THIRD-PARTY-NOTICES file and the licenses folder in the install directory, and are available on request. Those licences govern those components.
  • Some optional features download third-party software when you ask for them (for example the RIFE frame-interpolation engine and a film LUT pack, both from GitHub). Those downloads are made by their own authors under their own licences; you choose whether to install them, and you are responsible for complying with their terms.
  • The Software is sold, licensed and updated through Steam; our website runs on Cloudflare and our email on Zoho. Their services are subject to their own terms; we are not responsible for outages of their services, but the Software does not need our website or email to run, so an outage of them does not stop you using it.

9. Privacy

Our Privacy Notice explains that the Software itself sends us nothing — licensing and updates run between Steam and you — what Valve shares with us as a Steamworks partner (sales and wishlist totals, aggregate usage figures, public reviews), and how we handle anything you choose to send us. It is shown with these terms and is available at any time under Settings → About.

10. Consumer guarantees and your legal rights

If you acquire the Software as a consumer in New Zealand, the Consumer Guarantees Act 1993 applies and nothing in these terms excludes, restricts or modifies your rights under it. Consumers in other countries may have similar rights under their local law that we cannot exclude; nothing here limits them.

If you acquire the Software for the purposes of a business, you agree that the Consumer Guarantees Act 1993 and sections 9, 12A and 13 of the Fair Trading Act 1986 do not apply to the supply, and that it is fair and reasonable for the parties to be bound by this clause. This is the written agreement those Acts require.

11. Warranty

Beyond the guarantees the law gives you, the Software is provided “as is”. We do not promise that it will be free of bugs, that it will suit every PC, graphics card or Windows configuration, or that it will meet your particular needs. We work to fix problems that are reported to us, but we cannot promise a fix or a timeframe.

12. Limitation of liability

To the extent the law allows:

  • we are not liable for indirect or consequential loss, loss of profit, loss of data, or loss of use arising from the Software or these terms, however caused;
  • our total liability to you for all claims relating to the Software is limited to the amount you paid (through Steam) for the Software in the 12 months before the event giving rise to the claim.

These limits do not apply to liability that cannot be excluded or limited by law, including your rights under the Consumer Guarantees Act 1993 where it applies.

13. Ending the licence

You can stop using the Software at any time by uninstalling it through Steam. We may end your licence if you materially breach these terms (for example by circumventing licensing), if Valve refunds or reverses the payment for it, or if we are required to by law. We will not end a valid perpetual licence for our own convenience. When a licence ends, you must stop using the Software and uninstall it. Sections 6, 7, 10, 11, 12 and 15 continue to apply.

Uninstalling through Steam leaves your data folder (%LOCALAPPDATA%\Pronoisseur) in place; delete it yourself if you want your library, settings and thumbnails gone.

14. Changes to these terms

We may update these terms. The revision number and date at the top tell you which version you are reading. If we make a material change, the Software will show the new terms for your acceptance the next time it starts. If you do not accept them, you can decline and close the Software; contact us at [email protected] if you want to discuss it.

15. General

  • Who can agree. You must be old enough to enter into a binding contract where you live. If you are using the Software for an organisation, you confirm you are authorised to accept these terms for it.
  • Governing law. These terms are governed by the laws of New Zealand. The courts of New Zealand have non-exclusive jurisdiction; this does not prevent you from relying on consumer protections, or bringing a claim in a tribunal or court, where you live.
  • Whole agreement. These terms, the Privacy Notice, and the Steam store page at the time you bought make up the whole agreement between you and us about the Software. The Steam Subscriber Agreement governs the purchase transaction with Valve.
  • Severability. If part of these terms is found unenforceable, the rest still applies.
  • No waiver. If we do not enforce a term straight away, we can still enforce it later.
  • Assignment. We may transfer this agreement to a successor to our business; you may not transfer your licence to anyone else.
