Terms

Draft of 10 November 2026. Effective date: [to be set when reviewed]

Who you’re agreeing with

Riku is provided by Riku AI LLC, a Wyoming limited liability company (“Riku”, “we”, “us”). By making an account or using a Riku app, you agree to these terms. If you use Riku for a company, you’re agreeing for that company and confirming you’re allowed to.

Your account

• You need to be at least 18 to make an account.
• You sign in with a link we email you. Keep your email account secure: anyone who can read it can sign in as you.
• You’re responsible for what happens in your workspace, including what the people you invite do.

Your content stays yours

You own what you put into Riku: your instructions, documents, pasted text and the links you point it at. You give us permission to store, copy and process it only as needed to run your apps and the service. You confirm you have the right to use that content, and that sharing it with the people you send links to is allowed.

Your apps and your visitors

• You decide what your apps say and who can open them. You’re responsible for the apps you publish and for being honest with your visitors that they’re talking to an AI.
• If your app collects visitors’ emails or other details, you’re responsible for having a reason to collect them and for telling visitors how you’ll use them.
• When a person on your team steps into a conversation, that’s you talking, not Riku.

AI answers can be wrong

Riku apps answer from the context you give them, but AI models still make mistakes. Check what matters. Don’t use Riku as the only source for medical, legal, financial or safety decisions, and don’t let an app promise anything you wouldn’t stand behind.

Using your own model key

If you add your own OpenAI, Anthropic, Google or OpenRouter key, requests made with it are between you and that provider. Their terms and their charges apply, and those charges are yours.

What you can’t do

• Break the law, or help anyone else to.
• Build apps that deceive, harass, or impersonate a real person or business you don’t represent.
• Upload content you don’t have the right to share, or that contains malware.
• Try to get round plan limits, overload the service, or get into accounts or data that aren’t yours.
• Use Riku in a way that breaks the usage rules of the model provider behind your app.

If an app breaks these rules, we may take it offline, and we’ll tell you why when we can.

Plans and payment

• You can use Riku on the Free plan. Paid plans and their prices are shown in the app before you pay.
• Paid plans renew automatically until you cancel. You can cancel any time from Billing; your plan runs to the end of the period you’ve paid for.
• Payments are handled by Stripe. [Reviewer: refund policy and taxes.]
• If we change what a paid plan costs, we’ll email you at least 30 days before it affects you.

Ending things

You can close your account at any time. We may suspend or close an account that breaks these terms or puts other people or the service at risk. Where we can, we’ll warn you first and give you a chance to fix it. After an account closes we delete its data as described on the privacy page.

The service as it is

We work hard to keep Riku running and your data safe, but we provide it “as is”. We can’t promise it will never be down, never lose anything, or suit every purpose. We may change or remove features; if a change takes away something important on a paid plan, we’ll tell you first.

Limits on our liability

As far as the law allows, Riku isn’t liable for indirect or knock-on losses (such as lost profits or lost data), and our total liability to you is limited to what you paid us in the 12 months before the claim. Nothing here limits liability that the law doesn’t allow us to limit. [Reviewer: consumer carve-outs for UK/EU users.]

The law that applies

These terms are governed by the laws of the State of Wyoming, USA. [Reviewer: venue and dispute wording.]

Changes and contact

If we change these terms in a way that matters, we’ll update the date at the top and email builders before it takes effect. Questions: [contact email].
