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:
- every matching listing will be found, or found within any particular time;
- alerts will always be delivered, on time, or without interruption;
- listing details (price, condition, location, availability, MOT data) are complete or accurate — always check the original listing and the vehicle itself before buying;
- a listing will still be available when you act on it; or
- the Service will be free of faults or always available.
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:
- resell, redistribute, or commercially exploit the Service or the data it shows you beyond your own use of finding items;
- copy, scrape, or extract data from the Service itself using automated means, or attempt to access it other than through the app and website we provide;
- reverse engineer, interfere with, overload, or attempt to disrupt the Service or its security;
- use the Service to break the law, infringe anyone's rights, or breach any marketplace's own terms; or
- use another user's account or share yours.
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.
- How to subscribe (at launch). Subscriptions are available through the iOS App Store. Web subscriptions are not yet available and will be added shortly after launch; when they open, sign-up will start your subscription on the day you sign up (no free trial on web).
- Free trial (iOS only). When you subscribe through the iOS App Store, Apple provides a 7-day free trial. If you do not cancel before the trial ends, your subscription begins and you are charged the plan price.
- How you're billed. On iOS, payment is taken through your Apple Account under Apple's terms. When web subscriptions open, payment will be taken through Stripe. Subscriptions renew automatically for successive periods until cancelled.
- Cancelling. You can cancel anytime — on iOS via your Apple Account subscription settings; on web (once available) via your account settings or by contacting us. Cancellation stops the next renewal; you keep access until the end of the period you've paid for.
- Refunds. Your statutory rights under UK consumer law apply. Because a free trial is provided on iOS so you can evaluate the Service before paying, we do not generally refund part-used subscription periods, except where the law requires or at our discretion. For iOS purchases, refunds are handled by Apple.
- Price changes. We may change plan prices; we'll give you reasonable notice before a change affects you, and you can cancel if you don't accept it.
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:
- An individual marketplace may become temporarily unavailable to us — sometimes for hours or days. When that happens we keep monitoring the others and restore coverage as soon as we're able.
- We may add, pause, or remove marketplace coverage without notice where a third party's terms, availability, or technical measures require it.
- Alert delivery depends on providers outside our control (Apple and Google for push, and our email provider) — we can't guarantee every alert arrives, or arrives instantly.
- We don't commit to any specific uptime, alert speed, or completeness of matching results, on any plan.
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:
- We provide the Service with reasonable care and skill, but as described in section 4 we do not guarantee results, uninterrupted availability, or the accuracy or completeness of third-party listing data.
- We are not liable for losses that were not reasonably foreseeable, for business losses (including lost profit, lost deals, or wasted time or travel), or for anything arising from a marketplace, a seller, or a third party we do not control.
- Our total liability to you for any claim connected with the Service is limited to the amount you paid us for the Service in the 12 months before the claim.
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.
