Plus± is a product design and frontend development studio. This page explains who we are, how to contact us, and the legal information relating to this website and service. It's the shortest page in our Trust Centre, because saying who you are shouldn't take long.

| Support | [email protected] or through your dashboard |
| Billing | [email protected] |

About Plus±
Plus± provides product design and frontend development as a subscription, primarily to SaaS founders and software companies. Work is delivered asynchronously through a client dashboard, on a request-by-request basis. Most client communication takes place through the dashboard rather than scheduled meetings or long email threads. What we do — and what we deliberately don't — is described on our How it works page; the commercial details live in our Terms of Service.
Intellectual property
Briefly, because our Terms of Service cover this properly:
- The content of this website — text, design, and code — belongs to Plus± unless stated otherwise.
- Our logos, branding, and trademarks may not be used without prior written permission.
- Client work belongs to clients, as set out in the Terms.
- Third-party trademarks mentioned anywhere on this site remain the property of their respective owners.
- Open-source software we use or ship remains under its own licence.
External links
Where we link to external websites, we do so for convenience. We choose links carefully, but we don't control third-party content and aren't responsible for it — or for what it becomes after we linked to it. Inclusion of a link should not be interpreted as an endorsement of the organisation or its views.
Copyright
The text, artwork, graphics, branding, and source code of this website are © 2026 Boom Pow Limited, all rights reserved unless stated otherwise. If you'd like to reproduce or republish material beyond what applicable law permits, please contact us first. We grant permission more often than people expect; we simply prefer to be asked.
Dispute resolution
This website and our services are governed by applicable law as set out in our Terms of Service, which also describe how contractual matters are handled.
Our honest preference, stated here as everywhere else: talk to us first.
Updates
Company details change — addresses, representatives, registrations. When they do, this page is updated, and the date at the top changes with it. The version published here is always the current version. Previous versions are available on request where appropriate.

Every company asks for trust. The least it can do is make it easy to see who is behind the service you're using. If anything on this page is unclear, or if you need additional legal or company information, we'd be happy to help.
