Terms of use.

These terms govern your use of Anvil for iPhone. By using the app you agree to them.

The app

Anvil is licensed to you, not sold. You may use it on any Apple device you own or control, as permitted by the App Store Terms of Service. You may not rent, lease, lend, sell, redistribute or sublicense it, nor copy, decompile, reverse engineer or disassemble it except where the law expressly allows that despite this restriction.

Anvil is provided as is. To the maximum extent the law permits, it comes with no warranty of any kind, and we are not liable for any loss arising from your use of it. Nothing here limits any right you have as a consumer that cannot lawfully be limited.

Anvil Pro

Anvil Pro is an auto-renewing subscription sold through the App Store, by the month or by the year. Payment is charged to your Apple Account at confirmation. It renews automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel it in your Apple Account settings. Prices are shown in the app before purchase. We may change what Pro includes, and if a change materially reduces it you may cancel.

Models, and what you make with them

Anvil runs machine-learning models on your iPhone. Some are offered in the app's model list and some you may import yourself. Anvil renames the models it packages rather than retraining them; each one is listed with what it is based on and the licence it carries, and those licences travel with the model.

What a model produces follows from its weights and from what you ask for. We do not review, approve or store what you generate — it is made on your device and stays there unless you move it. You are responsible for what you create with Anvil and for complying with the law where you are and with the licence of the model you are using.

Anvil refuses one thing outright, in every build, under every model: it will not generate images that place a child alongside sexual or undressed subject matter. That refusal is made on your device, before any model is asked, and no setting or subscription lifts it. Attempting to circumvent it is a breach of these terms.

Use restrictions carried by the image models

Anvil's image models are derivatives of Stable Diffusion, licensed under the CreativeML Open RAIL++-M licence. That licence requires its use restrictions to be passed on to you as an enforceable term, so they are reproduced here in full and form part of this agreement. You agree not to use the models, or derivatives of them:

In any way that violates any applicable national, federal, state, local or international law or regulation.
For the purpose of exploiting, harming or attempting to exploit or harm minors in any way.
To generate or disseminate verifiably false information and/or content with the purpose of harming others.
To generate or disseminate personal identifiable information that can be used to harm an individual.
To defame, disparage or otherwise harass others.
For fully automated decision making that adversely impacts an individual's legal rights or otherwise creates or modifies a binding, enforceable obligation.
For any use intended to or which has the effect of discriminating against or harming individuals or groups based on online or offline social behavior or known or predicted personal or personality characteristics.
To exploit any of the vulnerabilities of a specific group of persons based on their age, social, physical or mental characteristics, in order to materially distort the behavior of a person pertaining to that group in a manner that causes or is likely to cause that person or another person physical or psychological harm.
For any use intended to or which has the effect of discriminating against individuals or groups based on legally protected characteristics or categories.
To provide medical advice and medical results interpretation.
To generate or disseminate information for the purpose to be used for administration of justice, law enforcement, immigration or asylum processes, such as predicting an individual will commit fraud/crime commitment (e.g. by text profiling, drawing causal relationships between assertions made in documents, indiscriminate and arbitrarily-targeted use).

If you import a model of your own, its licence is between you and whoever published it, and you are responsible for honouring it.

Privacy

What Anvil stores and what can leave your iPhone is set out in the privacy policy, which forms part of these terms.
