Terms of use

Last updated 17 October 2026

These terms are the agreement between you and Islarium Ltd ("we", "us") for using Plan-Zero — our website and the Plan-Zero app (together "the Service"). By creating an account or using the Service, you agree to them. If you use the Service for an organisation, you confirm you're allowed to accept these terms on its behalf, and "you" includes that organisation.

Islarium Ltd is a company registered in England and Wales (company number 17525132), registered office 71–75 Shelton Street, Covent Garden, London WC2H 9JQ. Contact: hello@plan-zero.com.

1. For business use

Plan-Zero is a professional tool for businesses and people working in a trade or profession. If you use it as a consumer, nothing in these terms affects your legal rights as a consumer.

2. The beta

Plan-Zero is in beta. That means features may change, be added or removed, and you may find bugs. During the beta the Service is free. We'll give you at least 14 days' notice before paid plans start, and you can then choose a paid plan or carry on with the Free plan. Please keep your own copies (exports) of anything important, as we can't guarantee work won't be lost during the beta.

3. Your account

4. Plans, fees and payment

This section applies once paid plans are available.

5. Your content

You own the projects, units, products, artwork, files and other content you create or upload ("your content"). You give us permission to store, copy, process, display and send your content only as needed to provide and improve the Service and to do what you ask (for example, when you share a project or export it).

You confirm that you have the rights needed for your content — including any brand names, logos, packaging artwork and product images in it — and that it doesn't break the law or anyone else's rights. We treat your content as confidential and only use it as these terms and our privacy policy describe.

6. Sharing

When you share a project, the people you share it with can see it (and, where the feature allows, comment on it). You decide who to share with and you're responsible for sharing appropriately, especially where a project contains a client's confidential packaging.

7. Library requests

If you send products to be added to a shared product library, you give us a worldwide, non-exclusive, royalty-free and permanent licence to review, adapt (for example, optimise) and include them in Plan-Zero's libraries for other users. You confirm that you own the products or have permission from their owner to do this. We may decline a request, or remove a product from a library, at any time.

8. Product libraries and trademarks

Product libraries show products and brands that belong to their owners, for planning and presentation. Showing them doesn't mean their owners endorse Plan-Zero. You may use library models within the Service and in the images, PDFs and presentations you make with it, but you must not extract, copy, share or sell the library files themselves, or use them outside the Service. Private libraries may only be used by the organisations they're made available to.

9. Acceptable use

You must not:

10. Our intellectual property

The Service — including its software, design, built-in units and products, the unit and product generators and the Plan-Zero name and logo — belongs to Islarium Ltd or our licensors. We give you a personal, non-transferable right to use it in line with these terms while your account is open.

11. Availability and changes

We work hard to keep the Service running smoothly, but we can't promise it will always be available or free of errors, and we may need to pause it for maintenance. We may improve or change the Service over time. Unless we agree otherwise in writing (for example, in an Enterprise agreement), the Service is provided without any guaranteed level of service.

12. Ending your use

You can stop using the Service and close your account at any time. We may suspend or close your account if you seriously or repeatedly break these terms, don't pay, or put the Service or other users at risk; where it's reasonable, we'll warn you first. When an account closes, you'll have 30 days to export your content, after which we delete it as described in our privacy policy.

13. Our responsibility to you

14. Claims about your content

If someone makes a claim against us because your content infringes their rights or breaks the law, you agree to cover our reasonable costs of dealing with it.

15. Changes to these terms

We may update these terms from time to time. We'll tell you about important changes by email or in the app at least 14 days before they take effect. If you keep using the Service after that, the new terms apply.
