Terms of Service

Last updated: 22.10.2026

These Terms govern your use of Lumen ("the Service"), operated by Bruo Systems Limited, 2c Grangegorman Lower, Smithfield, Dublin, Ireland (Reg. 765033). By using the Service you agree to these Terms.

The service

Lumen lets you generate images from text prompts using third-party AI models. You buy credits in advance and credits are consumed each time you generate.

Accounts

You sign in with your email and a one-time code. You are responsible for keeping access to your email secure.

Who the Service is for

You may open and use an account for yourself or for a studio, company or other organisation. When you use it for an organisation, that organisation is the customer under these Terms and is responsible for the account and everything bought through it, and you confirm you are authorised to accept these Terms on its behalf.

Rights that the law gives only to consumers, such as the statutory right to withdraw from an online purchase, apply to an individual buying for personal use and not to an organisation buying for its business. Everything our policies promise applies to every customer alike.

Sanctions

We do not accept new sign-ups or specialist applications from Russia, Belarus, Iran, North Korea, Syria or Cuba. The checks we perform are: the country of the IP address at sign-up and when someone applies as a specialist; the email address at sign-up, which is refused on those countries' national domains and on major Russian and Belarusian email providers; the country of residence a specialist declares; and the billing country at checkout. We do not accept payments with a billing country among these countries. An existing account holder keeps access to their account and balance.

Acceptable use

You may not use the Service to create unlawful, infringing, or harmful content, or to impersonate others. We may suspend accounts that breach these Terms.

Credits and payment

Credits are purchased in advance and are non-transferable. You buy them in the currency you select at checkout (USD, EUR, GBP, KZT, AZN, JPY, TRY, SAR, MAD, QAR, BHD or LKR), and prices are shown on the Pricing page and again at checkout. A single purchase is from €1 to €20,000, or its equivalent in the currency you pick at the day's rate. If a render fails or is cancelled, for any reason, including when a model's safety filter stops it, the credits charged for it are returned to your balance automatically. See the Payment Policy and Refund Policy for details.

Content

You keep the rights you hold in the prompts and reference images you submit. We claim no ownership of the images you generate: subject to these Terms and applicable law, you may use them for any lawful purpose, including commercial use, and we add no visible watermark. Some models embed invisible provenance data (such as content-credential metadata) in their output, which we do not remove. You are responsible for how you use generated content, including checking that it does not infringe anyone else's rights.

Images are produced by third-party AI models. They can be inaccurate, unexpected, or unsuitable for a particular purpose, and they may resemble output generated for someone else from a similar prompt. We make no warranty as to their accuracy, originality or fitness for any purpose. Check generated content before you publish it or rely on it.

Specialists

Besides the studio, Lumen has a catalogue of specialists: human designers and retouchers who refine and retouch generated images, make brand visuals and campaign sets, and do custom work the AI can't. You hire a specialist for a service. Each service has a base price in credits and each specialist sets a minimum price per hire; the price of a service with a specialist is the larger of the two. You see it before you hire, and you are charged exactly that.

If you want to offer your services as a specialist, the Specialist Agreement (/specialist-agreement) sets out the terms that apply to you.

Hiring a specialist

When you hire a specialist, the price in credits is taken from your credit balance and held for that hire. Nothing is charged to your card when you hire; credits are bought separately, as described in the Payment Policy (/legal/payment). The held credits are released to the specialist only when you accept the delivery or it is accepted automatically.

The specialist has 72 hours to accept the hire. If nobody accepts it in that time, the hire is cancelled and the full price is returned to your credit balance automatically. You can cancel a hire yourself until the specialist accepts it, and the full price is returned to your credit balance. If the specialist declines the hire before starting, or withdraws after accepting because they cannot do the work, the full price is returned to your credit balance automatically.

Specialist work: delivery, acceptance and changes

The work is delivered in the hire's task thread on the site, as messages and file attachments of up to 4 MB each (PNG, JPEG, WebP, SVG, PDF or ZIP). Until the specialist accepts the hire, the thread is read-only; after that, both of you can write in it. Only you, the specialist and the Lumen team can read it. Delivered files stay available on the hire page after the hire is completed.

After a delivery you can accept it, request changes (up to 2 rounds per hire), or open a dispute. If you do nothing for 7 days after a delivery, it is accepted automatically. When a hire is completed, the rights in the delivered work pass to you; after a dispute decision, they pass for the part of the price you paid.

Disputes

You can open a dispute from the hire page while the hire is in progress or delivered, giving a reason. The Lumen team reviews the thread and decides within 5 business days, returning anywhere from none to all of the price to your credit balance. The team acts as a mediator between you and the specialist. A dispute does not affect any statutory right you have.

Refunds of hires

Every refund of a hire is returned as credits to your credit balance, and every movement shows as a row in your credit history. Turning credits back into money follows the Refund Policy (/legal/refunds).

How specialists are reviewed

Before a specialist is listed, our review team looks at their application: their profile, the services they picked and their result in a short quiz on those services. Applicants give a date of birth to confirm they are at least 18, which we check and do not store, and declare their country of residence. Applications from the countries listed under Sanctions are refused. We do not collect identity documents from specialists. The review team decides within 5 business days.

Delivery

Nothing physical is sold or shipped. Renders arrive in your studio as soon as they finish. Work from a specialist arrives in the hire's task thread, as described above.

Availability

The Service is provided on an "as is" basis. We work to keep it available but do not guarantee uninterrupted access.

Liability

To the extent permitted by law, our liability for any claim relating to the Service is limited to the amount you paid us in the three months before the claim.

Governing law

These Terms are governed by the laws of Ireland, where Bruo Systems Limited is established. The courts of Ireland have jurisdiction over any dispute, which does not remove any right you have to bring a claim in the courts of your own country of residence if you are a consumer.
