Terms of service

Last updated: 6 September 2026

These Terms of Use govern your use of the List Mantis app and website (the "Service"). By creating an account or using the Service, you agree to them. If you do not agree, please do not use the Service. How we handle your data is covered separately in our Privacy Policy.


1. Who we are

List Mantis is operated by Whale and Wave Digital Ltd ("we", "us", "our"), registered in England and Wales (company number 17188418), registered office 66 Paul Street, London EC2A 4NA. Contact: hello@listmantis.com.

2. What List Mantis does

List Mantis alerts you when new public listings on third-party marketplaces match a search you have saved, and brings those alerts into one feed. It is an alerting and monitoring tool. It does not sell items, does not act as an intermediary in any transaction, and does not handle any purchase, payment, message, or delivery between you and a seller. All buying happens on the marketplace itself, under that marketplace's own terms.

List Mantis covers UK listings only. It monitors listings on UK marketplaces and filters out listings outside the United Kingdom, and is intended for use in the UK.

3. We are not affiliated with the marketplaces

List Mantis is an independent service. We are not affiliated with, endorsed by, or partnered with Facebook / Meta, AutoTrader, Gumtree, eBay, Vinted, or any other marketplace, and their names and trademarks belong to their respective owners. We refer to them only to describe which public listings our alerts cover. eBay data is accessed through eBay's official API; MOT data through the official DVSA MOT History API.

4. What we don't promise

We work hard to make alerts fast and accurate, but the Service depends on third-party marketplaces we do not control. So we do not guarantee that:

List Mantis is a tool to help you find listings faster. It is not a guarantee of any purchase, deal, saving, or profit, and nothing in the Service is financial, legal, or purchasing advice. Decisions you make on the back of an alert are your own.

5. Your account

You must be 18 or over to use List Mantis. Keep your login details secure; you are responsible for activity under your account. Tell us promptly at hello@listmantis.com if you think your account has been compromised.

6. Acceptable use

You agree to use the Service only for your own lawful use of finding listings, and not to:

We may suspend or close accounts that breach these terms.

7. Subscriptions, trial, billing and cancellation

The Service requires a paid subscription. Current plans and prices are shown in the app and on our website.

8. Changes to the Service

We may add, change, or remove features — including which marketplaces are covered — as the Service develops, or where a third party's terms, availability, or technical measures require it. We won't remove a core paid feature during a period you've paid for without offering a fair remedy.

9. Service availability, marketplace outages and delivery channels

List Mantis aggregates listings from several independently-operated third-party marketplaces (currently Facebook Marketplace, eBay, Gumtree, AutoTrader and Vinted). Each one can change its site, its terms, or its technical measures at any time, and we route around problems as best we can. Because of that:

We treat a marketplace being offline as an active problem to fix, not an accepted limitation, and we work to restore coverage as quickly as we can. Where a marketplace is unavailable for a prolonged period, we'll usually show a status note in the app.

10. Intellectual property

The List Mantis app, website, branding, and the way we present data are owned by us or our licensors. We grant you a personal, non-transferable, non-exclusive right to use the Service under these terms. Listing content belongs to the sellers and marketplaces it comes from; MOT data is licensed under the Open Government Licence v3.0.

11. Our liability

Nothing in these terms limits liability that cannot be limited by law (including for death or personal injury caused by our negligence, or for fraud). Subject to that:

If you are a consumer, you have legal rights that these terms do not affect.

12. Ending your use

You can stop using the Service and close your account at any time. We may suspend or end your access if you breach these terms or where we reasonably need to. Sections that by their nature should survive (for example sections 4, 10 and 11) continue to apply after your use ends.

13. Law and disputes

These terms are governed by the law of England and Wales, and disputes are subject to the courts of England and Wales — though if you live elsewhere in the UK you may bring proceedings in your own jurisdiction. If something's wrong, contact hello@listmantis.com first; we'd rather fix it than fight about it.

14. General

If any part of these terms is unenforceable, the rest continues to apply. We may update these terms as the Service changes; we'll update the date above and, for material changes, tell you in the app or by email. Continuing to use the Service after a change means you accept the updated terms.
