These Terms of Use ("Terms") are a binding agreement between you and HeatSignal LLC, a Colorado limited liability company ("HeatSignal," "we," "us," or "our"). They govern your access to and use of HeatSignal (the "Service")—our website, mobile app, alerts, and related features. By creating an account, signing in, or otherwise using the Service, you agree to these Terms. If you do not agree, do not use the Service.
HeatSignal is a sneaker-collector tool that aggregates publicly available marketplace listing information and helps you track specific products and sizes, catalog your own collection, and connect with other collectors. We surface links and details so you can open listings on third-party sites.
We are not a retailer or auction house, and we do not hold inventory. We help collectors discover listings and, where you choose, arrange peer-to-peer deals with one another. Payments, escrow, and payouts for those deals are handled by a third-party payment processor (Stripe); we are not a bank and do not provide financial services ourselves. We do not guarantee that any listing is authentic, available, or fairly priced. We do not operate an affiliate or referral program in connection with the Service.
Sign-up is open: you create an account by verifying an email address through a one-time magic link. You agree that registration information you provide is accurate and that you will keep it up to date. We may, at our discretion, suspend or refuse access for accounts that violate these Terms or that create risk to other users or to the Service.
You may use the Service only if you have the legal capacity to enter a binding contract in your jurisdiction (for example, you are not barred from using the Service under applicable law). You are responsible for all activity under your account and for safeguarding access to your email and devices.
You agree not to misuse the Service. Without limiting other remedies, you must not: attempt to bypass access controls or scrape the Service in a way that harms performance or violates third-party site terms; use the Service for unlawful purposes; interfere with other users or our infrastructure; or attempt to reverse engineer or exploit the Service except as allowed by law.
Listings, images, prices, and seller information come from third parties. We do not control and are not responsible for their accuracy, completeness, or legality. Purchases, shipping, returns, and disputes occur solely between you and the marketplace or seller.
When you follow a link from HeatSignal, you leave our Service; that site’s terms, privacy policy, and policies apply.
The Service—including its software, design, branding, and compiled presentation—is owned by us or our licensors and is protected by intellectual property laws. Subject to these Terms, we grant you a limited, non-exclusive, non-transferable right to use the Service for personal, non-commercial purposes. You may not copy, modify, distribute, or create derivative works from our proprietary materials except as permitted by law or with our prior written consent.
Marketplace content remains the property of its respective owners.
HeatSignal offers optional paid subscription plans (currently Pro and Elite) that increase how many pairs you can receive alerts for and how quickly those alerts are delivered. Tracking pairs and viewing the Signal Feed remain free. The plan name, length (monthly or yearly), and price—including the per-period price—are shown to you at the point of purchase before you confirm.
Auto-renewal. Paid subscriptions are auto-renewing. Unless you cancel, your subscription automatically renews at the end of each billing period (monthly or yearly) and your payment method is charged the then-current price for the next period. You may cancel at any time; cancellation takes effect at the end of the current paid period, and you keep your paid features until then. Except where required by law or by the applicable app store, payments are non-refundable and we do not provide refunds or credits for partial periods.
Purchases made through Apple (iOS). If you subscribe through the Apple App Store, payment is charged to your Apple ID account at confirmation of purchase. The subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours prior to the end of the current period. You can manage your subscription and turn off auto-renewal in your Apple ID Account Settings after purchase. Apple may charge any unused portion of a free trial, if offered, when you buy a subscription. These app-store terms supplement, and where required by Apple control over, the billing terms in this section.
Purchases made on the web. Web subscriptions are billed through our payment processor (Stripe). You can change or cancel your plan, and access billing receipts, from your account's plan settings.
Price changes. We may change subscription prices. If a change affects your renewal price, we will give notice in advance (for example, by email or an in-app notice) and the new price applies to the next renewal after the notice period; you may cancel before it takes effect.
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE." TO THE FULLEST EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. We do not warrant that the Service will be uninterrupted, error-free, or free of harmful components, or that any listing information is current or correct.
TO THE FULLEST EXTENT PERMITTED BY LAW, IN NO EVENT WILL HEATSIGNAL LLC, ITS MEMBERS, MANAGERS, EMPLOYEES, CONTRACTORS, OR AGENTS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICE. OUR TOTAL LIABILITY FOR ANY CLAIM ARISING OUT OF THESE TERMS OR THE SERVICE IS LIMITED TO THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE SERVICE IN THE TWELVE (12) MONTHS BEFORE THE CLAIM OR (B) ONE HUNDRED U.S. DOLLARS (US$100), IF YOU HAVE NOT PAID US. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS; IN THOSE CASES OUR LIABILITY IS LIMITED TO THE MAXIMUM EXTENT PERMITTED BY LAW.
You will defend, indemnify, and hold harmless HeatSignal LLC and its members, managers, employees, contractors, and agents from any claims, damages, losses, or expenses (including reasonable attorneys’ fees) arising from your use of the Service, your violation of these Terms, or your violation of third-party rights.
We may suspend or terminate access to the Service at any time, with or without notice, including for conduct that we believe violates these Terms or creates risk or legal exposure. You may stop using the Service at any time. Provisions that by their nature should survive (including disclaimers, limitations of liability, and indemnity) will survive termination.
We may modify the Service or these Terms. When we update these Terms, we will revise the “Last updated” date above. If changes are material, we may provide additional notice (for example, by email or a notice in the app). Your continued use after the effective date constitutes acceptance of the revised Terms.
These Terms are the entire agreement between you and us regarding the Service and supersede prior understandings on the subject. If any provision is unenforceable, the remaining provisions remain in effect. Our failure to enforce a provision is not a waiver.
Governing law. These Terms are governed by the laws of the State of Colorado and the United States, without regard to conflict-of-law rules. The state and federal courts located in Colorado have exclusive jurisdiction over any dispute arising out of or relating to these Terms or the Service, unless applicable law requires otherwise. You and HeatSignal LLC consent to personal jurisdiction in those courts.
Questions about these Terms: email support@heatsignal.app. We do not publish a postal address or phone line for general support on this page; for legal service of process, contact HeatSignal LLC through its registered agent on file with the Colorado Secretary of State.
