Terms of service

Last updated November 2, 2026

These terms are the agreement between you and Knyte Group Ltd ("we", "us") for using Yuumeh, the canvas at yuumeh.com where you and Yuumeh-chan, our AI assistant, make images and videos. By creating an account or using Yuumeh you agree to them. If you buy something, our Credits & refunds policy also applies, and our Privacy policy explains how we handle your data.

Who can use Yuumeh

You must be at least 18 years old and able to make a binding agreement. If you use Yuumeh for a company, you confirm you're allowed to accept these terms on its behalf.

Keep your sign-in safe. You're responsible for what happens under your account, including credits spent by people you invite to your projects.

What Yuumeh does

Yuumeh is a shared canvas. You write prompts, upload images and videos, connect cards together and generate new images and videos with AI models run by our model providers. Yuumeh-chan can read your canvas, arrange cards, write prompts and propose generations; she only spends credits when you confirm a take, or when you've switched her to Automatic, in which case she starts the takes she proposes herself (you can switch back to Ask me first at any time).

AI output can be unexpected, inaccurate or similar to other people's output. Check anything important before you rely on it or publish it.

We may add, change or remove models and features. Model providers can change or withdraw models, so a model you used before may not always be available.

Your content

You keep whatever rights you have in what you put into Yuumeh (prompts, uploads, notes) and in what you generate, as far as the law allows. AI-generated material may not be protected by copyright in every country.

You give us a worldwide, non-exclusive licence to store, copy, process and display your content only as needed to run Yuumeh for you and the people you share projects with, including sending it to our model providers to generate results. This licence ends when you delete the content or your account, except for copies we must keep by law.

You confirm you have the rights and permissions needed for everything you upload, including the consent of any recognisable person and of anyone whose voice you clone. Clone only your own voice or a voice whose speaker has agreed.

What you must not do

Don't use Yuumeh to make or share anything illegal; sexual content involving anyone under 18 or anyone who looks under 18; intimate or sexual images of a real person without their consent; content that impersonates, defames, harasses or threatens someone; deceptive deepfakes of real people; or material that infringes someone else's rights.

Don't try to get around limits, credit charges, safety filters or sign-up protections; don't access other people's projects without an invitation; don't attack, overload, scrape or reverse-engineer the service; and don't resell access without our written agreement.

Our model providers have their own usage rules, and generations must follow them too. We may block prompts or results that break these rules, and we may suspend or close accounts that do. Where the law requires, we report illegal content to the authorities.

Sharing and working together

Project owners decide who can edit or view their canvas. Anyone you invite can see the project's cards, prompts and media, and editors can change them. Each person pays for the generations they start, from their own credits or a team wallet they belong to.

Credits, plans and payments

Generations cost credits. Plans renew automatically until you cancel, and prices include VAT where it applies. How credits work, when they expire and when you can get a refund are set out in our Credits & refunds policy, which is part of these terms.

Ending your account

You can delete your account at any time from Settings. Projects you own are deleted for everyone, and unused credits are forfeited.

We may suspend or close an account that breaks these terms, puts others at risk, or that we're required to close by law. If we close your account without you having broken these terms, we'll refund unused credits you paid for.

Our responsibility to you

We provide Yuumeh with reasonable care and skill, but we can't promise it will always be available, error-free or that any generation will meet your expectations.

If you're a consumer, nothing in these terms affects your legal rights. We're responsible for loss or damage you suffer that is a foreseeable result of us breaking these terms or failing to use reasonable care. We're not responsible for business losses if you use Yuumeh for a business, or for losses that weren't foreseeable.

If you use Yuumeh for business, our total liability to you in any 12 months is limited to what you paid us in that period. Nothing limits liability for death or personal injury caused by negligence, for fraud, or for anything else that can't be limited by law.

Changes to these terms

We may update these terms. If a change matters, we'll tell you by email or in Yuumeh before it takes effect. If you don't agree, you can stop using Yuumeh and delete your account before the change applies.

The law that applies

These terms are governed by the law of England and Wales. If you're a consumer living elsewhere in the UK, you can also bring proceedings in your home courts, and you keep the protections of the law where you live.
