Terms of Service

Last updated: 29 September 2026

These terms are a contract between you and ME ASPECT LTD (company number 14471480, registered office Unit 10 EDEAL Business Centre, Dittons Park, Dittons Road, Polegate, BN26 6HY), trading as MarginLens. By creating an account or connecting your Amazon Seller Central account, you agree to them. Our Privacy Policy explains how we handle data and forms part of these terms.

Business use only

MarginLens is provided to businesses and sole traders for business purposes. It is not offered to consumers, and consumer protection rules that apply only to consumers do not apply to it. By signing up you confirm you are acting in the course of a business.

The service

MarginLens reads sales, financial, fee, inventory, advertising and related data from your own Amazon Seller Central account, with your authorisation, and presents it as dashboards, reports and alerts. It does not place orders, change listings or prices, or take any other action on your Amazon account. It reads.

Your account

Free trial

Your 14-day free trial of the Software plan starts the moment you connect your Amazon account. No card is taken and nothing is charged during the trial. When the 14 days end, the trial simply ends; to keep using MarginLens you subscribe from the Account page on our website. Nothing is charged unless you do. One trial per Amazon seller account. If you subscribe before your trial ends, you are not charged for your plan until it does. A guided setup call, if you add one, is charged when you subscribe.

Plans

There are two plans, shown with their current prices on marginlens.net:

The software is the same on both plans; Review adds the call and the written actions, not features.

The Review call

The guided setup call

Prices and VAT

Founding prices

Billing, cancelling and refunds

Acceptable use

You agree not to:

We may suspend or close an account that breaks these rules. Where practical we will warn you first.

Amazon's own terms

Your use of Amazon Seller Central, the Selling Partner API and Amazon Ads remains governed by Amazon's terms and policies. MarginLens is not affiliated with, endorsed by or sponsored by Amazon.

Figures are not advice

Everything MarginLens shows — profit, fees, VAT, payout estimates — is calculated from data Amazon provides and may include estimates, which the app labels as such. It is not financial, tax or legal advice. Check anything that matters against your own Amazon reports and take professional advice for tax filings and similar decisions.

No warranty, and the limit on our liability

MarginLens is provided "as is" and "as available". We do not promise it will be uninterrupted or error-free, or that it will suit your particular purpose, and we exclude any warranties implied by law to the extent the law allows.

To the extent permitted by law we are not liable for indirect, incidental or consequential loss, or for lost profits, lost revenue, lost data or business interruption, arising from your use of the service. Our total liability to you for everything arising out of or in connection with these terms and the service, in contract, tort or otherwise, is capped at the fees you paid us in the 12 months before the claim arose. Nothing in these terms excludes liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot be excluded by law.

The iPhone app

If you use the MarginLens app for iPhone, these terms apply to it. These terms are between you and ME ASPECT LTD, not Apple, and Apple is not responsible for the app or its content. Apple has no obligation to provide maintenance or support for it; support comes from us at admin@marginlens.net. Apple is not responsible for any claim relating to the app, including product liability claims, claims that it fails to meet a legal or regulatory requirement, or consumer protection claims; any such claim is for us to deal with, to the extent these terms do not exclude it. If anyone claims the app infringes their intellectual property, we, not Apple, are responsible for dealing with it. You confirm you are not in a country subject to a US government embargo or on a US government list of prohibited or restricted parties. Apple and its subsidiaries are third-party beneficiaries of this section and may enforce it. Your use of the app must also follow the App Store's usage rules.

Changes to the service or these terms

We may change the service, and these terms, from time to time. For a change to these terms that affects you materially we will tell you in the app or by email at least 14 days before it takes effect. Continuing to use MarginLens after that is acceptance of the change; if you do not accept it, cancel before it takes effect.

Governing law

These terms are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction over any dispute about them or the service.
