Version: 1.0 Effective date: 9 October 2026
1. Who we are and what these terms cover
1.1 XEWI is provided by KF Premium LTD, a company registered in England and Wales with company number (to be confirmed) and registered office at (to be confirmed) ("XEWI", "we", "us", "our").
1.2 These Terms of Service ("Terms") govern your access to and use of the XEWI platform, including the web application, APIs, integrations, reports, recommendations and any related services (together, the "Service").
1.3 By creating an account, ticking the acceptance box at sign-up, or using the Service, you agree to these Terms and to the documents they refer to:
- the Privacy Notice;
- the AI Use Policy;
- the Acceptable Use Policy;
- the Cookie Notice; and
- where we process personal data on your behalf, the Data Processing Addendum ("DPA").
1.4 If you accept these Terms on behalf of a company or other organisation, you confirm you have authority to bind it, and "you" means that organisation.
2. Eligibility and business use
2.1 The Service is a business tool for people and organisations selling on Amazon. You must be at least 18 and must use the Service for the purposes of your trade, business, craft or profession.
2.2 You confirm that you are acting in the course of business and not as a consumer.
2.3 If you are a consumer under the law that applies to you (for example, you bought a Silent Tribe bundle as an individual for personal learning), nothing in these Terms removes the rights you have as a consumer that cannot be excluded by contract, including any statutory right to cancel. Where these Terms conflict with those rights, those rights prevail.
3. Your account
3.1 You must give accurate information when you register and keep it up to date.
3.2 You are responsible for keeping your login credentials confidential and for everything done under your account. Tell us promptly at hello@xewi.app if you believe your account has been compromised.
3.3 Each account belongs to one business (tenant). You may invite team members where your plan allows it, and you are responsible for their use of the Service.
4. Connecting your Amazon accounts
4.1 Much of the Service works by connecting to your Amazon Selling Partner account (via the Amazon Selling Partner API) and your Amazon Advertising account (via the Amazon Ads API). You authorise these connections through Amazon's own consent screens, and you can revoke them at any time in Amazon Seller Central or Amazon Advertising, or by disconnecting them in XEWI.
4.2 By connecting an account, you authorise us to access the data and perform the actions that the permissions you grant allow, solely to provide the Service to you and as described in our Privacy Notice.
4.3 You confirm that you are entitled to connect each account you connect, and that doing so does not breach any agreement you have with Amazon or anyone else.
4.4 You remain solely responsible for your Amazon accounts: your listings, pricing, advertising spend, inventory, compliance with Amazon's policies (including the Amazon Services Business Solutions Agreement, Amazon's Advertising Agreement and program policies), product safety and legality, tax and VAT, and your obligations to your own customers. XEWI is an independent service. We are not Amazon, we are not affiliated with or endorsed by Amazon, and we have no control over Amazon's decisions, including account suspensions, listing removals, API changes or data availability.
5. How actions on your Amazon account are approved
5.1 The Service can prepare changes that affect your money or your brand. These include bid and budget changes, negative keywords, listing copy and images, and workflow actions ("Actions").
5.2 By default, no Action that spends money or changes your listings is sent to Amazon until you, or a team member you authorise, approve it. Proposed Actions are held in an approval queue until you approve or reject them. The Service shows where an approval only takes you to Amazon to make the change yourself, and does not change anything directly.
5.3 Automations you switch on. Some features can act without a per-change approval only if you expressly enable them. For example:
- a repricing rule set to apply price changes without approval;
- automatic pricing enabled for a product; or
- review requests sent to your buyers in bulk when you run that automation.
When you enable such an automation, you instruct us to carry out every Action it produces, within the limits you set, and you are responsible for those Actions as if you had approved each one. You can switch an automation off at any time; this stops future Actions but does not reverse ones already sent.
5.4 When you approve an Action, or it is carried out by an automation you enabled, you are instructing us to submit it to Amazon on your behalf, and you are responsible for that decision. Review every Action and every automation's settings before approving or enabling them.
5.5 Automated workflows that prepare Actions stop for your approval before any money or brand Action is submitted, unless you have enabled an automation under clause 5.3.
6. Plans, fees and payment
6.1 The Service is offered on the plans described at https://xewi.app/#pricing, which currently include:
- Free: limited features, at no charge;
- Pro: £99 per month (or as stated at the time of purchase), billed in advance; and
- Silent Tribe bundle: a one-off payment of £2,997 (or as stated at the time of purchase), which includes 12 months of paid access to the Service, at the plan level stated at the time of purchase, together with the Silent Tribe course and community.
6.2 Some features unlock progressively as your account meets milestones (for example, connecting Amazon, running a live campaign, or 30 days of sales history). Plan and feature descriptions in the Service form part of these Terms.
6.3 Prices exclude VAT and other applicable taxes unless stated otherwise. You are responsible for any taxes due, other than taxes on our income.
6.4 Payments are processed by our payment provider, currently Stripe, under its own terms. We do not store full card details.
6.5 Subscriptions renew automatically at the end of each billing period until cancelled. You can cancel at any time, and cancellation takes effect at the end of the current billing period. Fixed-term access (such as the Silent Tribe bundle's 12 months) ends at the end of that term unless you renew.
6.6 We may change our prices on at least 30 days' notice. A price change takes effect from your next billing period after the notice period. If you do not agree, you can cancel before it takes effect.
6.7 If a payment fails, we may suspend paid features after telling you, until payment is received.
7. Refunds
7.1 Except where required by law, or as set out in clause 2.3 or this clause 7, fees are non-refundable, including for partial billing periods and unused features.
7.2 This clause does not affect any statutory right you have as a consumer under clause 2.3.
8. What the Service does, and does not, promise
8.1 The Service gives you information and recommendations. It does not give you guarantees. Market data, estimates (for example of sales, revenue, demand or margin), scores, verdicts ("Enter", "Avoid", "Enter if…"), competitor analyses and forecasts are estimates and hypotheses, not statements of fact. They are based on data from Amazon, third-party data providers and statistical and AI models, all of which can be incomplete, delayed or wrong.
8.2 In particular:
- sales and revenue figures derived from sales rank or "bought in past month" badges are ranges and floors, not exact numbers;
- statements about competitors (for example that one seller reacts to another's price changes) are hypotheses drawn from public data, not facts about those competitors; and
- a gap in the data (for example, too little review volume) is reported as a gap and does not mean something does not exist.
8.3 You make your own business decisions. We do not guarantee any particular sales, profit, ranking, advertising performance, product outcome or Amazon account status. Nothing in the Service is financial, legal, tax, customs, product-safety or investment advice. Take professional advice where you need it, especially before sourcing a product, committing to stock or signing supplier agreements.
8.4 The Service relies on third-party services outside our control, including Amazon's APIs, data providers and cloud infrastructure. Their availability, limits and accuracy may affect the Service, and features that depend on them may be temporarily unavailable.
8.5 We will provide the Service with reasonable skill and care. Beyond that, and to the extent the law allows, the Service is provided "as is" and "as available", and we exclude all other warranties, conditions and terms, whether express or implied (including fitness for a particular purpose and satisfactory quality).
9. Acceptable use
9.1 You must use the Service lawfully and in line with the Acceptable Use Policy and Amazon's policies. In particular, you must not:
- use the Service to manipulate reviews, rankings, or other sellers' listings, or to engage in any practice Amazon prohibits;
- attempt to access other customers' data, or probe, scan or test the vulnerability of the Service, except under a written agreement with us;
- reverse engineer, scrape, resell or sublicense the Service or its data, or use it to build a competing product;
- upload anything unlawful, infringing, or containing malware; or
- use the Service's outputs to make claims about identifiable competitors that you present as fact rather than as analysis.
9.2 We may suspend or restrict access if we reasonably believe you are breaching this clause, if your use threatens the security or stability of the Service, or if Amazon requires it. Where reasonable, we will tell you first and give you a chance to fix the problem.
10. Your data and ours
10.1 Your Data. You keep all rights in the data you provide or that we obtain from your connected accounts ("Your Data"). You grant us a non-exclusive licence to host, copy, process and display Your Data only as needed to provide, secure and support the Service, and as described in the Privacy Notice.
10.2 Aggregated insights. We may create aggregated and de-identified data and statistics, for example market-level sales curves derived from rank data, that do not identify you, your customers or your products as yours. We may use them to operate and improve the Service.
10.3 Personal data. Where we process personal data on your behalf (for example, your customers' data within Amazon order or VAT reports), we do so as your processor under the DPA, which forms part of these Terms. Where we act as controller (for example, your account and billing details), the Privacy Notice applies.
10.4 Our IP. We and our licensors own the Service, including its software, models, designs, documentation, and the methods and content we provide. These Terms give you a limited, non-exclusive, non-transferable right to use the Service during your subscription for your internal business purposes. All other rights are reserved.
10.5 Outputs. Subject to these Terms and to third-party rights, you may use the reports, recommendations, listing copy, images and other outputs the Service generates for you ("Outputs") in your business. See the AI Use Policy for the limits of AI-generated Outputs. You are responsible for checking that Outputs you publish (for example, listing copy or images) are accurate, lawful and do not infringe anyone's rights.
10.6 Feedback. If you send us suggestions, we may use them without obligation to you.
11. Confidentiality and security
11.1 Each party will keep the other's confidential information confidential and use it only to perform these Terms, except where disclosure is required by law.
11.2 We use appropriate technical and organisational measures to protect the Service and Your Data. These include encryption of connection credentials, tenant isolation, access controls and monitoring, as described in the Privacy Notice. No system is perfectly secure, and you are responsible for securing your own devices and credentials.
12. Liability
12.1 Nothing in these Terms limits or excludes liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, or any other liability that cannot be limited or excluded by law.
12.2 Subject to clause 12.1, we are not liable for any:
- loss of profits, revenue, sales, business, contracts or anticipated savings;
- loss of or damage to goodwill or reputation;
- advertising spend, stock purchases, supplier commitments or other costs you incur relying on the Service or its Outputs;
- consequences of Actions you approved, Actions carried out by automations you enabled, or decisions you made using the Service;
- suspension, restriction or loss of your Amazon account or listings, or any Amazon decision;
- loss or corruption of data, where it could have been prevented by reasonable backups on your side or is caused by a third-party service; or
- indirect or consequential loss,
in each case whether arising in contract, tort (including negligence), breach of statutory duty or otherwise.
12.3 Subject to clauses 12.1 and 12.2, our total liability to you in any 12-month period, arising out of or in connection with these Terms or the Service, is limited to the fees you paid us for the Service in the 12 months before the event giving rise to the claim (or £100 if you have paid nothing).
12.4 You will indemnify us against third-party claims arising from your breach of clauses 4.3, 4.4, 5.3 or 9, or from content you publish using the Service.
13. Suspension and termination
13.1 You can stop using the Service and close your account at any time by emailing hello@xewi.app.
13.2 We may terminate or suspend your account on written notice if you materially breach these Terms and do not fix the breach within 14 days of being asked to (where it can be fixed), or immediately where the law, Amazon, or a serious security risk requires it.
13.3 We may discontinue the Service or any feature on at least 60 days' notice. If we discontinue the whole Service, we will refund any prepaid fees for the unused period.
13.4 After termination, your right to use the Service ends. We will delete or de-identify Your Data within the period set out in the Privacy Notice. Before that, you can ask us for an export of the data you are entitled to. Clauses that by their nature should survive termination (including 8, 10, 11, 12, 17 and 18) will survive.
14. Changes to the Service and to these Terms
14.1 We improve the Service continuously and may change features. We will not make changes that materially reduce the core functionality of a paid plan during a paid period without telling you and giving you the option to cancel with a pro rata refund.
14.2 We may update these Terms. We will give at least 30 days' notice of material changes by email or in the Service. Continuing to use the Service after the change takes effect means you accept it. If you do not agree, you may cancel before then.
15. Beta and free features
Features labelled beta, preview or experimental, and the Free plan, are provided without any commitment on availability or support, and may change or be withdrawn at any time.
16. Third-party services
The Service integrates with third-party services (including Amazon, Stripe, data providers and AI model providers listed in our Sub-processor List). Your use of those services is subject to their terms, and we are not responsible for them.
17. General
17.1 Force majeure. Neither party is liable for delay or failure caused by events beyond its reasonable control, including failures or changes of third-party platforms such as Amazon.
17.2 Assignment. You may not transfer these Terms without our consent. We may transfer them to a successor of our business, and will tell you if we do.
17.3 Entire agreement. These Terms, and the documents they refer to, are the entire agreement between us about the Service.
17.4 Severability, waiver and third parties. If any part is found unenforceable, the rest remains in force. Not enforcing a right is not a waiver of it. No one else has rights under these Terms under the Contracts (Rights of Third Parties) Act 1999.
17.5 Notices. We send notices to the email address on your account. You send notices to hello@xewi.app or to our registered office.
18. Governing law and disputes
18.1 These Terms and any dispute arising from them are governed by the law of England and Wales.
18.2 The courts of England and Wales have exclusive jurisdiction, except that if you are a consumer resident elsewhere in the UK you may also bring proceedings in your local courts.
18.3 Before starting proceedings, please contact us at hello@xewi.app so we can try to resolve the issue informally.
