Terms of service
Effective 25 September 2026. Written in plain language on purpose — this is the actual agreement. If you need something specific for your organisation, talk to us.
The basics
By using hiy you agree to these terms and to our Acceptable use rules. If you don’t agree, don’t use the service.
Your account
Keep your sign-in credentials to yourself, give us accurate information, and be at least 16. You’re responsible for what happens under your account. One rule matters above the rest: a twin may only represent you, or a product you own — see Acceptable use.
Your content stays yours
You keep ownership of everything you upload. You grant us only the permission needed to run the service: to store your material, index it, and use it to generate your twin’s answers.
You confirm you have the right to use the material you add, and that the twin represents you.
Our service
We aim to keep hiy available and working, but it’s provided as-is. We don’t guarantee uninterrupted service, and we don’t guarantee that a twin’s answers are accurate — a twin can be wrong, which is why every answer that can show its sources does. The same is true when your Support Agent answers for your product: its end users get answers on this as-is basis exactly as direct visitors do, and you — not hiy — remain responsible for your own product’s commitments.
Don’t rely on a twin for professional advice, and don’t present one as a substitute for it.
Plans and payment
Today the Free plan is the only purchasable reality; its limits are shown on the pricing page. When paid plans launch, prices are shown before you pay, trials start when your twin goes live rather than when you sign up, and honesty features — citations, “I don’t know”, AI disclosure — are never paywalled. If a price changes, existing subscribers hear about it before it affects them.
Early Access works differently. While a spot is open, claiming one is free and needs no card, for a fixed number of days — today 30 — starting when you make your first agent rather than when you claim the code. It runs on usage allowances of its own, and we may pause or end a workspace’s grant to guard against abuse or a shared cost budget running out. Ending or pausing a grant never deletes anything: you keep your agents, their knowledge and every conversation. If that happens before paid plans are open, chat and training pause until they are — see Early Access for the limits, the days remaining, and what a paused workspace can still do.
Availability and changes
The product is under active development. Features may change, and we’ll keep the roadmap honest about what’s live versus intended.
We can change these terms at any time. If a change is material, we’ll email everyone with an account at least 30 days before it takes effect; smaller changes — clarifications, fixes — take effect as soon as they’re posted. The Effective date at the top of this page always shows the version in force. Continuing to use hiy after a change takes effect means you accept it — if you don’t, delete your account instead.
Ending it
You can delete any agent, or your whole account, at any time from Settings → Data & privacy. Deleting an agent removes its material, its index, its conversations and anyone who left contact details with it; material it shared with your other agents stays in your Knowledge Hub. Deleting the account removes all of it. Either way we hold the address each agent answered at for 90 days, so that nobody else can take a link people may already have saved.
We can also refuse, suspend or end your access to hiy at any time and for any reason — normally with notice, but immediately for abuse, a security risk, a breach of these terms or Acceptable use, or where the law requires it. If we end a paid plan without cause, we’ll refund any unused prepaid time.
Liability
To the extent the law allows, we’re not liable for indirect or consequential losses arising from your use of hiy, or from what a twin says.
