Terms of service

Last updated 30 August 2026

These terms govern your use of Shelfproof, provided by Webgro Ltd, registered in England and Wales. Installing the app means you accept them.

What the service does

Shelfproof reads prices from public competitor product pages you nominate, shows them to you in the Shopify admin, and optionally displays them on your storefront alongside your own price.

Your responsibilities

You choose which competitor pages to track and whether to display them, and those choices are yours in law as well as in practice. In particular:

  • Comparisons must be like-for-like: the same product in the same size or pack. We refuse to show a price when a competitor’s page covers several variants, but we cannot verify that a page you link is the right product.
  • Displaying a competitor’s name or domain on your storefront may engage trademark and comparative advertising law, which varies by country. Masking reduces that exposure but does not remove it. The decision, and the liability for it, is yours.
  • If the block makes reference pricing more prominent on your pages, local rules on “was” pricing may apply to you.
  • You must not use Shelfproof to track pages behind a login or paywall.

What we undertake

  • We identify our crawler honestly, honour robots.txt, rate-limit per site, and back off when asked. We do not attempt to evade blocking.
  • We never invent a price. Where we cannot read one cleanly we show nothing, and every price displayed carries the date it was read.
  • We will remove any competitor domain from our system on request from that domain’s owner, for all merchants.

Accuracy

Prices are read from third-party websites that we do not control and may change at any time. We take care to read them correctly and to date everything we display, but we do not warrant that a competitor’s price is current or correct at the moment a shopper sees it.

Billing

Paid plans are charged through Shopify and appear on your Shopify invoice. We never see your card details. Charges recur every 30 days until cancelled. Cancelling takes effect at the end of the period you have paid for; we do not refund part-periods.

Suspension and termination

You may uninstall at any time. We may suspend an account that is using the service to place unreasonable load on third-party sites, that tracks pages behind authentication, or that is the subject of a credible complaint from a site owner. We will tell you why.

Liability

Nothing in these terms limits liability for death, personal injury or fraud. Otherwise, our total liability in any 12-month period is limited to the fees you paid us in that period, and we are not liable for lost profits or indirect loss. Because you control what is displayed on your storefront, we are not liable for claims arising from your display of a competitor’s name or price.

Changes

We will give at least 30 days’ notice by email before any change that materially reduces the service or increases the price of a plan you are on.

Governing law

These terms are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction.
