Terms of service

In short

This summary is here so the document is easy to read. It is not part of the agreement and does not change anything below it; where the two differ, the clauses govern.

• You install one of our apps on your store. You keep your data. We use it to run the app, and never to train AI models.
• The assistant’s answers are generated, so they can be wrong. It speaks in your store’s name, and what it says to your shoppers is your responsibility to oversee.
• Free costs nothing. Paid plans are flat monthly amounts in US dollars, billed through Shopify, with no per-conversation, per-visitor or per-product charges.
• Cancel any time. You drop to Free rather than being switched off, and you keep the paid features until the period you have paid for runs out.
• We do not offer an uptime guarantee, and we do not answer your shoppers for you.
• Your rights under the Australian Consumer Law are not affected by anything here.

1. Who these terms are between

These terms are between Thomas James Nicholas and Zachary Gerald Engledow as trustees for the NE Investments Unit Trust (ABN 98 959 967 159), trading as Zero Four Five (we, us, our), and the business that installs or uses one of our apps (you, the merchant).

Our apps — StoreChat AI and the others listed on this site — are each a Service. Where a term applies to only one app, it says so. The people who chat with the assistant on your storefront are shoppers; they are your customers, not ours.

2. Accepting these terms

You accept these terms when you install a Service on your store, create an account, or use a Service — whichever happens first. If you are accepting for a company, trust or other entity, you confirm you have authority to bind it, and “you” means that entity. If you do not accept these terms, do not install or use the Services.

3. What the Services do

StoreChat AI places an assistant on your storefront that answers shopper questions using your own store content — products, variants, policies and pages that we sync from your store through the store platform’s authorised API. Depending on your plan it can also capture leads, look up orders for a shopper who verifies themselves, follow custom answers and hand-off rules you write, and send you summaries and reports. The plan pages describe what each plan includes.

We may change, add to or withdraw features. If a change materially reduces a feature you are paying for, we will give you at least 30 days’ notice and you may cancel and receive a refund of the unused portion of any fee you have already paid. We will not make a change that materially reduces the security of a Service or weakens our commitments about your data.

A feature we describe as beta, preview or experimental is supplied as it is, may change or be withdrawn without notice, and should not be relied on for anything important.

4. What the assistant does not promise

This clause matters more than any other on this page, so it is written plainly.

• Answers are generated, and generated answers can be wrong. The assistant produces its replies using an AI model. It can misread your content, miss context, or state something incorrectly and confidently. We do not warrant that any answer is accurate, complete or suitable for a particular shopper.
• You are responsible for what goes out under your brand. The assistant speaks in your store’s name. You decide whether to switch it on, what content it may draw from, what custom answers it gives, and when it hands off. Reviewing what it says to your shoppers is your job, and we give you the conversation logs so you can.
• It is not advice. Nothing the assistant says is legal, financial, medical, safety or other professional advice, and it must not be relied on as such by you or by a shopper.
• It does not commit you to anything on its own. Prices, stock, delivery dates, refunds and any other statement it makes should be treated as information drawn from your store, not as an offer or a promise made by us.
• There is no human takeover. The assistant is not staffed live chat. When a conversation needs a person, it hands the conversation to your team by the rules you set. We do not answer your shoppers for you.

If a use of a Service could cause harm when an answer is wrong — anything touching safety, health, dosage, compatibility, legal entitlements or money owed — do not put that use in front of shoppers without a human check. Clause 16 sets out the rights you have under the Australian Consumer Law regardless of this clause.

5. Telling shoppers they are dealing with an AI

The assistant identifies itself as an AI assistant rather than a person, and you must not configure or present it so as to suggest a shopper is talking to a human being.

Several jurisdictions now require that disclosure by law — from 2 August 2026, for example, Article 50 of the EU Artificial Intelligence Act requires people interacting with an AI system to be told so, and places obligations on both the provider of the system and the business deploying it. We handle the provider side. Meeting the obligations that fall on you as the business deploying it on your storefront — in every market where you sell — is your responsibility, and you should not assume our default wording discharges them. Tell us if your market needs particular wording and we will help where we reasonably can.

6. Your account

You are responsible for your account, for keeping credentials secure, and for everything done under it — including by your staff and anyone else you give access to. Tell us promptly at info@zerofourfive.com.au if you think an account has been compromised. We may act on instructions given through your account, and we may require verification before acting on a request made another way.

7. Your store data, and our role in it

You keep ownership of your store data, your content, and the shopper conversations that take place on your store (together, Your Data). You grant us a non-exclusive licence to host, copy, process, transmit and display Your Data for as long as you use the Service, and only for the purposes of operating, securing and supporting it — including sending the material needed to generate a reply to our AI provider.

We do not use Your Data to train our own AI models, and we use AI providers under commercial terms that do not use the data we send them to train theirs. We may change AI provider; if we do, that commitment travels with the change.

Much of the shopper information we handle is processed on your behalf. You are responsible for having a lawful basis to collect it, for your own privacy policy, and for telling your shoppers how their information is handled. Our handling is described in the privacy policy, which forms part of these terms. Where a data-handling question is covered by both documents, the privacy policy governs.

You are the controller of shopper personal data and we act as your processor. This applies to every merchant, wherever you are — not only where the UK GDPR, the EU GDPR or a comparable overseas regime applies to you. This clause is our data processing agreement with you; you do not need to ask for a separate one, though we will sign your own form of agreement on request.

The particulars of the processing are:

• Subject matter and duration: providing the Services to you, for as long as you use them, and then for the periods set out in clause 20 and the privacy policy.
• Nature and purpose: answering your shoppers’ questions, capturing enquiries you have asked us to capture, looking up an order when a shopper asks about their own, and reporting to you on all of it.
• Categories of personal data: the content of shopper messages; contact details a shopper submits through a form; the email address, postcode and order details used to verify and answer an order enquiry; and a randomly generated visitor identifier. The list in the privacy policy governs if the two differ.
• Categories of data subject: your shoppers and visitors to your store.

We will: process shopper personal data only on your documented instructions, your configuration of the Service being those instructions, and tell you if we believe an instruction breaches data protection law; ensure the people we allow to process it are bound by a duty of confidentiality; apply the security measures described in clause 15; assist you within reason with data subject requests, and with your obligations on security, breach notification and impact assessments; delete or return it as set out in clause 20; and make available the information reasonably needed to show we have met these obligations, including allowing and contributing to an audit you or your auditor conduct on reasonable notice, no more than once a year unless a regulator or an incident requires otherwise.

Sub-processors. You give us general authorisation to engage the sub-processors listed in the privacy policy, which we keep current. We will give you at least 30 days’ notice before adding or replacing one. If you reasonably object on data protection grounds within that period, tell us and we will work with you to find an alternative; if we cannot, you may cancel the affected Service without penalty and receive a pro-rata refund of anything paid for the unused period. We engage every sub-processor on terms no less protective than these and remain responsible to you for what they do.

We may generate aggregated, de-identified statistics about how the Services are used and use them to operate and improve the Services. These never identify you, a shopper or your store, and we do not publish them in a form that could.

We will not use your name or logo publicly as a customer reference without your consent.

8. Acceptable use

You must not, and must not permit anyone else to:

• use a Service unlawfully, or in breach of your store platform’s own terms;
• use a Service to send content that is deceptive, misleading, harassing, unlawful, or that infringes someone else’s rights;
• present the assistant as a human being, or hold its answers out as human-written;
• copy, resell, sublicense or provide a Service to a third party as your own, or use it to build a competing product;
• reverse-engineer, decompile or attempt to derive the source code, models or prompts behind a Service, except to the extent the law says you may;
• probe, scan or interfere with the security of a Service, or access it other than through the interfaces we provide;
• load a Service in a way designed to degrade it for others, or use automated means to drive volume that has nothing to do with real shoppers; or
• feed a Service content you do not have the right to use, or personal information you do not need it to have — particularly health, financial or other sensitive information.

Breach of this clause is grounds for suspension or termination under clause 19.

9. Plans, fees and billing

The current plans and prices are on the app page: Free at no charge, Pro and Scale as priced there. Prices are in US dollars.

How you are charged. Where you install through the Shopify App Store, billing runs through Shopify’s billing system: Shopify charges you, collects the money, applies any sales tax, GST or VAT it is required to collect, and shows the charge on your Shopify invoice. Shopify’s own terms govern that transaction, and any tax question about it is between you and Shopify. Where instead we invoice you directly, payment is due within 14 days and we will add any tax we are required by law to charge, shown separately on the invoice.

What is metered. Paid plans are flat. We do not charge per conversation, per visitor or per product, and a busy month does not cost more than a quiet one. The Free plan includes the monthly chat allowance shown on the app page. That allowance is a soft limit: if your store goes past it the assistant keeps answering for the rest of the month, and no charge arises. Your usage against the allowance is shown in the app admin, and we may ask you to move to a paid plan if it stays above the allowance.

Changes to price. We may change prices, but not during a period you have already paid for. We will give you at least 30 days’ notice before a change applies to your next billing period, and you may cancel before it takes effect. Continuing on a paid plan after that is acceptance of the new price.

Failed payment. If a payment fails or is reversed, we will tell you and give you a reasonable opportunity to fix it. If it is not resolved, we may downgrade you to Free or suspend the Service.

10. Trials

Installing gives your store a free trial of the paid feature set, of the length shown on the app page. The trial starts when you install, not when you choose a plan.

If you do nothing, you are not charged. When the trial ends your store moves to the Free plan and the assistant keeps working with the Free feature set and chat allowance. There is no automatic charge and we never hold your card — a paid plan begins only when you choose one and approve the charge through Shopify.

Choosing a paid plan during a trial does not forfeit the days you have left. Your remaining trial days carry across, so the first charge is raised when those days run out rather than straight away. We do not send trial-expiry reminders — your remaining days are shown in the app admin.

One trial per store; we may withdraw or shorten trials for accounts that appear to be cycling through them.

11. Cancelling, and what happens after

You can cancel a paid plan at any time from your store’s app admin, without giving a reason and without a cancellation fee. Cancellation takes effect at the end of the billing period you have already paid for — you keep the paid features until then. Fees already paid are not refunded for part of a period, except where clause 3 or clause 19 gives you a refund, where we have got the billing wrong, or where the Australian Consumer Law or another applicable law requires one.

Cancelling does not switch the assistant off. Your store drops to the Free plan and keeps working with the Free feature set and chat allowance. To stop a Service entirely, uninstall the app.

12. Availability and support

We do not offer a service level agreement, and this clause does not promise uptime. We run the Services on reputable infrastructure and we work to keep them available, but they can be interrupted by maintenance, by a fault, by your store platform, or by a provider we depend on. Where we can plan an interruption, we will try to take it at a quiet time and tell you first.

Support is by email at info@zerofourfive.com.au, supported by the in-app guides and assistant. We aim to answer within one business day, and sooner for Pro and Scale, but that is a target we work to rather than a guarantee. Business days are Monday to Friday, excluding public holidays in Queensland, Australia.

We do not provide live human chat cover for your shoppers on any plan.

13. Intellectual property

We own the Services — the software, models, prompts, designs, documentation and everything else we bring — along with any improvement to them. Nothing in these terms transfers any of it to you. You get a non-exclusive, non-transferable right to use the Services on your store while these terms are on foot and your account is in good standing.

You own Your Data and your trade marks, and nothing here transfers them to us. If you send us feedback or a suggestion, we may use it without obligation to you.

On the Free plan the assistant carries a small Zero Four Five attribution. Removing it is a paid-plan feature; please do not strip it another way.

14. Confidentiality

Each of us may receive information from the other that is confidential. Each will use the other’s confidential information only to perform these terms, protect it with at least reasonable care, and not disclose it except to people who need it and are under similar obligations, or where the law requires disclosure. This does not apply to information that is public through no fault of the receiver, already known to them, or independently developed.

15. Security and incidents

We take reasonable steps to protect Your Data, including encryption in transit, one-way hashing of passwords, access controls and reputable infrastructure providers, as described in the privacy policy. No system is completely secure and we cannot guarantee absolute security.

If we become aware of a security incident affecting Your Data, we will notify you without undue delay, tell you what we know, and take reasonable steps to contain and remediate it. Where the incident is a notifiable data breach, we will meet our obligations under Part IIIC of the Privacy Act 1988 (Cth), and assist you with yours.

16. Your rights under the Australian Consumer Law

Nothing in these terms excludes, restricts or modifies any guarantee, warranty, right or remedy under the Competition and Consumer Act 2010 (Cth), including the Australian Consumer Law, that cannot lawfully be excluded, restricted or modified. If any part of these terms would do so, that part does not apply to the extent of the inconsistency, and the rest of the agreement continues.

Being a business does not put you outside the Australian Consumer Law. Because the amount payable for the Services is well under the threshold in section 3 of the Australian Consumer Law, you are likely to be a consumer for its purposes, and the consumer guarantees — including that services are supplied with due care and skill, are reasonably fit for a purpose you tell us about, and are supplied within a reasonable time — apply to what we supply you. We do not ask you to give any of that up.

Nothing in these terms limits our liability for misleading or deceptive conduct under section 18 of the Australian Consumer Law, for fraud, or for our own wilful misconduct.

These terms are a standard form contract. If any term is unfair within the meaning of Part 2-3 of the Australian Consumer Law, it is void and the rest of the agreement continues without it. If you think a term here is unfair, tell us — we would rather fix it than argue about it.

17. Limits on our liability

This clause is subject to clause 16 in every respect.

Limitation permitted for this kind of service. Store assistant software of this kind is not ordinarily acquired for personal, domestic or household use or consumption. To the extent section 64A of the Australian Consumer Law allows, our liability for failing to comply with a consumer guarantee is limited, at our option, to supplying the Services again or paying the cost of having them supplied again — and we will not rely on that limit where it would not be fair and reasonable to do so.

Everything else is provided as it is. Apart from the guarantees and terms the law imposes and that cannot be excluded, we give no warranty that a Service will be uninterrupted or error-free, that its answers will be accurate, or that it will meet a particular requirement.

What neither of us is liable for. To the extent the law allows, neither party is liable to the other for loss of profit, loss of revenue, loss of anticipated savings, loss of goodwill or reputation, loss of or corruption of data, business interruption, or any indirect or consequential loss — however it arises, and even if the loss was foreseeable. In addition, and to the extent the law allows, we are not liable for loss arising from your reliance on an answer the assistant generated, from a decision you or a shopper made on the strength of one, from your configuration of a Service, or from an outage or change in a third-party service we depend on.

Cap. To the extent the law allows, our total aggregate liability arising out of or in connection with these terms and the Services — whether in contract, tort including negligence, statute or otherwise — is limited to the total fees you paid us for the Service in the twelve months before the event giving rise to the claim. Where you paid us nothing in that period, including on the Free plan, that cap is US$100. This cap does not apply to liability that cannot be capped by law, or to our fraud or wilful misconduct.

Contribution and apportionment. Each party’s liability is reduced to the extent the other caused or contributed to the loss, including by failing to take reasonable steps to mitigate it. Nothing in these terms is intended to exclude, limit or modify the operation of the proportionate liability regime in Chapter 2 of the Civil Liability Act 2003 (Qld), which cannot be contracted out of.

18. Indemnity

You indemnify us against loss, damage and reasonable costs we actually suffer from a third-party claim to the extent it arises from your breach of clause 8 (acceptable use), your infringement of another person’s intellectual property, or your handling of shopper personal information in breach of privacy law. The indemnity does not extend to any part of a claim caused or contributed to by us, and it is reduced accordingly.

We will tell you promptly about any such claim, let you conduct the defence of it if you wish, not settle it without your consent (which you will not unreasonably withhold), and take reasonable steps to mitigate. This clause is subject to clauses 16 and 17.

19. Suspension and termination

You may end this agreement at any time by uninstalling the Services from your store. Uninstalling ends the Shopify subscription in accordance with Shopify’s rules.

We may suspend or end your access if you materially breach these terms and do not fix it within 14 days of us asking, if payment fails and is not resolved after we have asked, if we reasonably believe continued use puts a Service, another merchant or a shopper at risk, or if the law requires it. Where the risk is immediate we may suspend first and tell you straight after, and we will restore access as soon as the risk is resolved. A suspension will be no broader and no longer than the reason for it requires.

We may also withdraw a Service entirely, or end this agreement for convenience, on 30 days’ notice — in which case we will refund the unused portion of any fee you have already paid.

On termination your right to use the Services stops and any fees owing become payable. Clauses 7 (as to ownership), 13, 14, 16, 17, 18, 20 and 26, and any other clause that by its nature should survive, survive termination.

20. Your data when it ends

When you uninstall, we stop syncing your store and stop the assistant. We then delete or de-identify Your Data on the timetable set out in the privacy policy, subject to any records we must keep by law, and we handle the mandatory data requests our store platform sends us within the times it requires. Export what you need — conversations, leads, reports — before you uninstall; if you ask us within 30 days of uninstalling and the data still exists, we will help you get a copy.

21. Third-party services

The Services depend on providers we do not control — your store platform, our AI provider, our email provider and our hosting provider, listed in the privacy policy. Their availability, changes and terms affect what we can deliver. Your relationship with your store platform is your own, and these terms do not vary it. Shopify is not a party to this agreement and owes you nothing under it.

22. Changes to these terms

We may update these terms. The current version always lives at this page with its version date at the foot. For a material change we will give at least 30 days’ notice by email or in the app before it takes effect, and you may cancel under clause 11 before it does. Continuing to use a Service after the change takes effect means you accept it. Changes we make to comply with the law may take effect on shorter notice where the law requires, and we will say so when we tell you.

23. Notices

We send notices to the email address on your account, or show them in the app; you send them to info@zerofourfive.com.au. An emailed notice is taken to be received on the next business day after it is sent, unless the sender knows it did not arrive. Keep your account email current — it is where billing, security and change notices go.

24. If you are outside Australia

We sell to merchants in many countries. Where the law of your own country gives you rights that cannot be excluded by agreement — consumer, data protection or otherwise — those rights are not affected by these terms, and nothing here is intended to deprive you of the protection of the mandatory law of the place where you are established. You are responsible for complying with the laws that apply to your own store, including consumer, privacy, marketing and AI-disclosure law in each market where you sell.

25. General

• Assignment. You may not assign these terms without our consent, which we will not unreasonably withhold. We may assign them to a buyer of the business, on notice to you, provided the buyer agrees to be bound by them.
• Entire agreement. These terms and the privacy policy are the whole agreement between us about the Services and replace anything said or written beforehand — but nothing in this paragraph limits liability for misleading or deceptive conduct or for any statement made fraudulently.
• Severance. If a provision is unenforceable, it is read down or struck out to the minimum extent needed, and the rest stands.
• Waiver. A right is not waived by not exercising it, or by delay.
• Relationship. Nothing here creates a partnership, employment, joint venture or agency between us.
• Force majeure. Neither party is liable for a failure caused by something genuinely outside its reasonable control, for as long as that lasts; payment obligations are not excused, and if it lasts more than 30 days either party may terminate.
• Disputes. Tell us first and give us a fair chance to fix it. Neither party starts proceedings about a dispute, other than for urgent interlocutory relief, until it has raised the dispute in writing and 14 days have passed. Nothing in this paragraph stops you complaining to a regulator, including the ACCC or the Office of the Australian Information Commissioner.
• Interpretation. Headings do not affect meaning; “including” and “for example” do not limit what precedes them; and these terms are not read against whichever of us drafted them.

26. Governing law

These terms are governed by the laws of Queensland, Australia. Each party submits to the non-exclusive jurisdiction of the courts of Queensland and the courts that hear appeals from them. “Non-exclusive” means neither of us is prevented from bringing proceedings somewhere else where the law allows it — see clause 24 if you are outside Australia.
