Terms of Service

1. The Service

Himiko lets you chat with AI models from several providers in one place. It can choose a model for you automatically (“Auto”) or let you pick one. Models, features, and limits may change over time.

2. Beta

Himiko is in beta. Features may change, be added or be removed, usage limits may be adjusted, and the Service may sometimes be unavailable while we improve it. We will tell you in advance before any change that would remove chats you have saved.

3. Eligibility and accounts

You must be at least 13 years old to use the Service, and have a parent or guardian's consent if you are under 18 or under the age of digital consent where you live. You may use the Service as a guest or create an account. You are responsible for activity on your account and for keeping your sign-in details secure; tell us at support@himiko.ai if you think someone else has used it.

4. Acceptable use

You agree not to use the Service to:

• break any law, or infringe anyone's rights, including intellectual property and privacy rights;
• create content that is harmful, harassing, hateful, sexually exploitative, or intended to deceive;
• make pictures of real people that could mislead or harm them, or copy others' artwork, logos or brands in ways that infringe their rights;
• find, track or expose private individuals;
• get around usage limits, access codes, or security measures; access the Service with bots, scrapers or other automated means without our permission; or overload it;
• copy, reverse engineer, or resell the Service or access to it without our permission; or
• break the usage policies of the underlying AI model providers.

We may remove content, limit, suspend or end access for anyone who breaks these rules.

5. AI output

Answers and pictures are generated by AI models and can be inaccurate, incomplete, or out of date, even when checked by a second AI. Do not rely on them as professional advice (including legal, medical, financial, or engineering advice). Check important information, and use your own judgement before acting on any answer. Similar requests may produce similar outputs for other people, so outputs may not be unique to you.

6. Your content

You keep any rights you have in the messages and files you submit, and, as between you and us, in the answers and pictures you receive. You give us permission to process your content as needed to run the Service, including sending it to AI model providers as described in the Privacy Policy. You are responsible for having the right to share any content you submit, and for how you use the outputs.

If you send us feedback or ideas (including thumbs up or down), we may use them to improve the Service without owing you anything.

7. Plans, mana, and payment

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders: it sells the paid plans and mana to you, handles payment, sales tax and VAT, invoices, and payment-related customer service. Paddle's buyer terms also apply to your purchase.

Some features require a paid plan. Paid plans are billed monthly and renew automatically until you cancel. You can cancel at any time from your account settings or from the link in your Paddle receipt; you keep access until the end of the month you have paid for, and you won't be charged again. We will tell you at least 14 days before any price increase, which then applies from your next billing month.

Usage is measured in mana: every answer uses mana, on every plan. The mana included with a plan refills as described on the pricing page and doesn't carry over; mana you buy separately stays valid for 12 months from purchase. Mana has no cash value and can't be transferred or exchanged for money, except through a refund under our Refund Policy.

8. Refunds

You can ask for a refund within 14 days of a payment, as set out in our Refund Policy. This doesn't limit any right to cancel or get a refund that you have by law.

9. Availability and changes

We work to keep the Service available but do not guarantee it will always be uninterrupted or error-free. Third-party model providers may change or remove models. We may change, suspend, or discontinue parts of the Service; if we end a paid plan, we will refund the unused part of what you have paid.

10. Disclaimers and limitation of liability

The Service is provided “as is” and “as available”. To the fullest extent permitted by law, we disclaim all warranties, and we are not liable for any indirect, incidental, special, or consequential loss, or for loss of data, profits, or goodwill. Our total liability for any claim relating to the Service is limited to the amount you paid us in the 12 months before the claim, or US$100, whichever is higher. Nothing in these terms limits liability that cannot be limited by law, such as for death or personal injury caused by negligence, or for fraud.

11. If you misuse the Service

If someone makes a claim against us because you broke these terms or the law while using the Service, you agree to cover our reasonable costs of that claim, to the extent the law allows. This doesn't apply to you as a consumer where the law where you live doesn't allow it.

12. Ending your use

You can stop using the Service at any time, delete your chats in the app, or ask us to delete your account (see the Privacy Policy). We may suspend or end your access if you break these terms or if we need to for legal or security reasons; if we end a paid plan without you having broken these terms, we will refund the unused part.

13. Your rights as a consumer

If you use the Service as a consumer, nothing in these terms takes away rights you have under the consumer protection laws of the country where you live, including rights that can't be limited or waived by contract.

14. Governing law and disputes

If you have a problem, please contact us first at support@himiko.ai; most issues can be sorted out quickly. These terms are governed by the laws of Singapore, and the courts of Singapore have jurisdiction over any dispute arising from them. If you are a consumer, you may also bring a claim in the courts of the country where you live, and the mandatory consumer laws of that country continue to apply.

15. Changes to these terms

We may update these terms. We will post the new version here and update the date above, and tell you in the Service or by email at least 14 days before a significant change takes effect. If you keep using the Service after a change takes effect, you accept the updated terms; if you don't agree, you can stop using it and cancel any paid plan.

16. General

These terms, the Privacy Policy and the Refund Policy are the whole agreement between you and us about the Service. If any part is found unenforceable, the rest still applies. If we don't enforce a right straight away, we haven't given it up. We may transfer these terms to a company that takes over the Service, and will tell you if we do; your rights under them stay the same.
