Terms of Service

Last updated 2026-10-22. Version 2026-10, the one recorded on your account when you accept.

These terms govern your use of MatterWave, the platform your AI apps run on. By creating an account you accept them on behalf of yourself and, where you sign up for an organisation, on behalf of that organisation. These are the pre-release terms for MatterWave. They will be updated before general availability, and the version you accepted is recorded on your account.

The service

MatterWave provides hosted access to language models and the applications built on them. Features, models and limits may change while the service is in development. We will give reasonable notice of changes that reduce what your organisation can do.

Your account

One email address, one account, one organisation. You are responsible for keeping your password private and for everything done through your account. Tell us at once if you believe it has been used without your permission.

An organisation's administrators may add members, attach a single sign-on provider, set spending limits and remove members. They act for the organisation, and the organisation is responsible for their actions.

Acceptable use

You may not use the service to break the law, to infringe another person's rights, to generate material intended to harm or deceive, or to probe, overload or interfere with the platform. We may suspend an account or an organisation that does so, and will say why unless the law prevents it. The Acceptable Use Policy{" "} sets out what is not allowed, the steps we take, and how to appeal.

Your content

What you send to a model and what it returns is yours. We store it so that your conversations persist and you can export or delete them, and we do not use it to train models. Operational metadata - token counts, model names, latency - is kept to run and bill the service.

Plans, fees and limits

Every plan includes a monthly allowance of tokens, counted with each model's multiplier, as listed on the Plans page. On the Free plan, requests stop at the allowance until the month resets.

An organisation's owner or administrators can subscribe to a paid plan on the Plans page, billed monthly or annually in advance at the listed price. A plan sold per seat is charged for each member. Where a plan offers a free trial, the payment method collected when subscribing is charged when the trial ends unless the subscription is cancelled first. Fees agreed with your organisation in writing take precedence over the listed prices.

On a monthly paid plan, usage past the allowance continues at each model's listed price and is billed as overage on the next invoice, up to an overage cap. The cap starts at the plan's monthly price (per seat, on a plan sold per seat) and an administrator can change it; once it is reached, requests are refused until the month resets. Annual plans have no overage: requests stop at the allowance until the month resets. An administrator can also set a spending budget that stops requests sooner.

A cancelled subscription runs to the end of the period already paid for. If a payment is late we tell your organisation, and may limit overage, new API keys and plan changes, and then move the organisation to the Free plan, until it is paid. Late payment never deletes your content.

Ending the agreement

You can delete your account at any time from Settings. We may end the agreement with notice, or without notice where an account breaches these terms. On termination your content is deleted after the retention period set out in the Privacy Policy.

Liability

The service is provided as-is during its pre-release period. To the extent the law allows, we are not liable for loss arising from model output, from downtime, or from anything you build on the platform. Nothing here limits liability that cannot be limited by law.

Changes to these terms

When the terms change we publish a new version here with a new date, and the version number recorded against your account tells us which text you accepted. Continuing to use the service after a change means accepting the new version.
