Terms of Service

Effective Date: August 30, 2026

Welcome to Euclid Travel, operated by LumoTravel LLC, a New York limited liability company ("Euclid Travel," "we," "us," or "our"). By accessing our website or using our services for monitoring and managing the travel you have already booked (the "Services"), you agree to be bound by these Terms of Service ("Terms").

PLEASE READ THESE TERMS CAREFULLY, AS THEY CONTAIN A BINDING ARBITRATION AGREEMENT AND CLASS ACTION WAIVER THAT AFFECT YOUR LEGAL RIGHTS.

1. Description of Service & Appointment of Agency

Euclid Travel provides services for travel you have already booked. Our core service monitors the price of your existing flight and hotel bookings and attempts to reprice eligible itineraries when a price drop is detected. We may offer additional services over time, which may include support for additional booking types (such as rental cars, rail, cruises, and short-term rentals), additional features (such as itinerary management, online check-in, and assistance when a trip is disrupted), and searching for and booking new travel at your direction. Additional services are described in the product, and the terms specific to each apply when you use it. Services that involve booking or purchasing travel on your behalf are not offered today. If and when we offer them, they are available only under the separate Tier 2 Transaction Authority described below, which you grant per feature. Not every service is available to every user or in every market, and we may add, change, or discontinue services.

By submitting a flight or hotel confirmation (a Passenger Name Record or "PNR" for flights, or a reservation/confirmation number for hotels) to us, or by connecting an email inbox (a "Connected Inbox," such as Gmail) for automatic syncing, you authorize Euclid Travel and its authorized personnel to act as your agent for the limited purpose described below. By connecting a Connected Inbox, you authorize us to automatically discover and enroll all eligible upcoming trips found in that inbox for monitoring and repricing, and you agree that such auto-discovered trips are subject to the same success fee (Section 2) as trips you submit manually.

Tier 1 — Repricing Authority (granted when you enroll a trip). This authorization grants us the authority to:

  • Interact with airlines, hotels, travel agencies, and booking platforms on your behalf.
  • Access reservations associated with itineraries you submit or that we discover through a Connected Inbox, including itineraries on which you, or others you are authorized to represent, are passengers or guests.
  • Modify, reprice, cancel-and-rebook, or otherwise alter such itineraries for the purpose of securing a lower price, a credit, or a refund on a booking you already hold.

This authority does not permit us to purchase new travel, to increase the total amount you have paid for a trip, or to act on your finances or property in any other respect.

Tier 2 — Transaction Authority (granted separately, per feature). Some services would require us to purchase travel or incur a charge on your behalf, rather than only to reduce a price you have already paid. We will never do this under your Tier 1 authority. Before we book, purchase, or commit funds on your behalf, we will present the specific authority we are asking for, the limits or approval steps that apply, and the fees involved, and we will obtain your separate, affirmative authorization for that service. You may withdraw Tier 2 authority at any time in your dashboard settings without affecting your Tier 1 enrollment. Any purchase we make under Tier 2 is also subject to the travel provider's own terms, fare rules, and cancellation policies.

Notice of Auto-Discovered Trips. When you connect a Connected Inbox, we show you the trips we discover and enroll, and we email you when we enroll a newly discovered trip. Every enrolled trip appears in your dashboard, where you can pause or remove it before a price drop is secured.

Scope and Revocation of the Agency. The authority you grant under this Section is a limited authorization to act as your agent, restricted to the Tier 1 and Tier 2 authorities described above, as applicable to the services you have enabled. It grants no authority over your finances, property, or any other matter beyond the Services, and is not a power of attorney. You may revoke our authority for any specific itinerary at any time by pausing or removing that trip in your dashboard; doing so stops monitoring and repricing of that trip going forward and excludes it from future automatic re-enrollment from your Connected Inbox. You may turn off automatic enrollment entirely, disconnect your Connected Inbox, or close your account at any time, which revokes this authorization. Any revocation takes effect prospectively and does not unwind a reprice already completed or a success fee already earned before the revocation took effect.

Trips Booked for Others. You represent and warrant that, for any itinerary you submit or that we discover through a Connected Inbox that includes passengers other than yourself, you are authorized to act on those passengers' behalf and to authorize Euclid Travel to do so, and you agree to indemnify and hold Euclid Travel harmless from any claim arising out of an itinerary you enrolled without such authorization. When you enroll a trip that includes other passengers, you do so as their authorized representative and you bind those passengers to these Terms — including the Limitation of Liability (Section 6), the Binding Arbitration agreement and Class Action Waiver (Section 7), and the Governing Law and Venue provisions (Section 8) — to the fullest extent permitted by law, and you agree to make them aware of these Terms before enrolling their trip. The success fee for any enrolled trip is charged to the payment method on file for your account, regardless of who travels.

2. Fees and Billing

Euclid Travel operates on a success-fee basis. We do not charge upfront fees or subscriptions.

  • Success Fee: If we successfully secure a price drop on your behalf, we charge a fee equal to twenty percent (20%) of the total savings secured.
  • Hotel Rebookings: For a refundable hotel reservation, we secure savings by rebooking the identical room at the lower rate. The 20% success fee is charged to your payment method on file at the time we complete that rebooking. We never charge a fee on a reservation we only monitor and do not rebook (including prepaid rates, which we monitor but do not rebook). If a rate drops more than once before your cancellation deadline, the fee is calculated on the difference between your original booked rate and the final rebooked rate, and is never summed across individual rebookings. If a rebooking we execute is ever not honored at the property, no fee applies and we will cover any resulting difference in cost.
  • Currency & Digital Credits: You explicitly acknowledge and agree that airline savings are frequently issued as digital airline credits, vouchers, or e-credits, while hotel savings are realized as a lower confirmed rate on a rebooked reservation. Euclid Travel's 20% success fee is charged in real United States Dollars (USD) to your payment method on file, regardless of whether your savings came in cash, as an airline e-credit, or as a lower rebooked hotel rate.
  • Points & Award Flights: For a flight booked with miles or points (an award ticket), we recover value by repricing your ticket in place so the airline redeposits miles to your loyalty account; the savings come back to you as miles, not cash. Because airlines do not assign a fixed cash value to miles, we convert the miles recovered to U.S. Dollars using a published, Euclid Travel-set valuation of each program's per-point value, refreshed at least quarterly, and our 20% success fee is charged on that estimated dollar value. If the cash taxes or co-pay on the repriced ticket increase, we subtract that increase from the estimated value first, so the fee is charged only on the net value you gained, never on more than you actually saved. This dollar figure is Euclid Travel's good-faith estimate, not a provider-confirmed cash amount; we make the per-program valuation and its as-of date available on request at legal@euclidtravel.ai, and we record the valuation applied to each charge so it can be audited and, if it ever overstated your savings, refunded under the refund right in Section 5.
  • Euclid Cash: Euclid Cash is a promotional credit we issue for referrals and other promotions. It is always earned, never sold; you cannot buy it, and we will not sell it to you. When you hold a balance, we apply it to your next success fee automatically and charge your payment method only for the remainder, so a fee we charge may be less than twenty percent (20%) of your savings, and may be nothing at all. Euclid Cash has no cash value. It is not a gift card, stored-value card, or prepaid access instrument; it is not transferable to another person or account; and it cannot be redeemed, exchanged, or withdrawn for cash. It does not expire while your account is open, and any unused balance is forfeited if you close your account or if we terminate it for a breach of these Terms. We may expand what Euclid Cash can be applied to, and we may withhold or void a balance obtained through fraud, abuse of a referral program, or duplicate or fake accounts.
  • Referrals: If you invite someone and they create a new account through your link, you and they each receive a Euclid Cash reward once we are actively monitoring their first eligible trip. Nothing is issued at signup. Rewards are limited to a maximum number of rewarded referrals per account, and are issued only for genuine new accounts belonging to different people; self-referrals, duplicate accounts, and automated signups are not eligible, and we may withhold or reverse a reward we determine was obtained that way. If you join through someone's link, that person can see your first name and whether we are monitoring a trip for you. We may change or end the referral program at any time, which does not affect rewards already issued.
  • Non-Refundable: Once an airline credit, hotel savings, or refund is successfully secured and the success fee is charged, the fee is strictly non-refundable. This does not override the surprise-charge refund right described in Section 5.

3. Savings, E-Credits, and Provider Policies

Euclid Travel's responsibility ends once the airline credit, hotel rebooking, or refund is successfully secured on your behalf.

  • Expiration and Use: Airline e-credits are subject to the specific terms, conditions, and expiration dates set by the issuing airline. Euclid Travel is not responsible for tracking, extending, or replacing expired e-credits. If you fail to utilize your secured credit before it expires, you are not entitled to a refund of the Euclid Travel success fee.
  • Force Majeure: Euclid Travel is not liable for changes in airline or hotel policies, technical outages on airline or hotel booking systems, or an airline's or hotel's refusal to interact with third-party agents that prevent us from securing a price drop.

4. User Responsibilities & Interference

You are responsible for ensuring the data you provide to Euclid Travel is accurate.

  • Change and Cancellation Penalties on Enrolled Trips: Euclid Travel is designed for changeable and refundable fares and refundable hotel rates. You are solely responsible for knowing your ticket's or rate's rules. You are responsible for any airline- or hotel-assessed change fee, cancellation fee, fare/rate difference, or penalty arising from our repricing of any enrolled trip, whether you submitted it or we discovered it through your Connected Inbox, and whether the trip is in your name or that of another passenger or guest you enrolled. For flights, repricing is performed in place. For refundable hotel reservations, repricing is performed by cancelling the original refundable booking and rebooking the identical room at the lower rate. If you do not want a particular trip repriced — for example, a restrictive or Basic Economy fare, or a hotel reservation you intend to keep exactly as booked — you must pause or remove it before a price drop is secured.
  • Fare Class & Rate Plan Changes: For flights, repricing keeps your cabin and fare type the same (for example, Main Cabin economy stays Main Cabin economy), but securing a lower price may move your ticket into a different fare class — the airline's internal booking code (such as Y, B, M, H, or K) that sits within that cabin. Fare class can affect how many redeemable miles or elite-qualifying credits a flight earns, your eligibility or co-pay for upgrades, and standby or change priority, depending on your airline's loyalty program. For hotels, we rebook directly with the chain to preserve your loyalty account, but a rebooked rate may sit on a different rate plan and change the points or elite-night credit a stay earns. If preserving a specific fare class or rate plan matters to you for mileage or status reasons, you must pause or remove that trip before a price drop is secured. Euclid Travel is not responsible for changes in miles or points earned, elite-qualifying credit, upgrade eligibility, or other loyalty benefits resulting from a reprice.
  • User Interference: If you manually modify, upgrade, or cancel your itinerary directly with the airline or hotel while Euclid Travel is monitoring or actively repricing your trip, you assume all risks associated with conflicting changes. Euclid Travel is not liable for lost savings, disrupted itineraries, or fees triggered by simultaneous user modifications.

5. Payments & Chargebacks

By saving a payment method with us (via Stripe) and connecting a Connected Inbox, you authorize Euclid Travel to store your payment credential and to initiate future charges that you do not separately approve at the time of each charge (a "merchant-initiated transaction"). You understand and agree that: (i) these charges are variable in amount and not on a fixed schedule — a charge occurs only when we secure a price reduction on an enrolled trip (a provider-confirmed lower fare or hotel rate for a trip paid in cash, or, for an award ticket, miles redeposited to your loyalty account); (ii) the amount is twenty percent (20%) of the savings, less any Euclid Cash balance we apply (Section 2), charged in U.S. Dollars — for a cash trip, the provider-confirmed savings; for an award ticket, the Euclid Travel-estimated dollar value of the miles recovered, calculated as described in Section 2 (Points & Award Flights); (iii) charges may be triggered by trips we automatically discover through a Connected Inbox, and by trips booked for passengers other than you; (iv) we will send a receipt for each charge to your account email; and (v) you may stop future charges at any time by turning off automatic enrollment, pausing or removing trips, disconnecting your inbox, or closing your account. This authorization remains in effect until you cancel it or close your account.

  • Disclosure Before You Authorize Charges: Before you provide a payment method or connect a Connected Inbox, we present to you, clearly and conspicuously and adjacent to the action that grants your consent, the material terms of the success-fee program: that the fee is 20% of your savings — provider-confirmed savings for a trip paid in cash, or Euclid Travel's published estimate of the value of the miles recovered for an award ticket — charged automatically to your payment method on file without separate approval at the time of charge; that trips we automatically discover through a Connected Inbox are enrolled and fee-eligible on the same terms as trips you submit; and how to turn off automatic enrollment and cancel. Your decision to proceed after that disclosure is your express informed consent to those terms.
  • Turning Off Automatic Enrollment / Cancelling: You may turn off automatic enrollment and stop all future success fees at any time, using a method at least as simple as the one you used to enable it: a single control in your dashboard settings ("Turn off automatic enrollment") and, if you connected an inbox, disconnecting that Connected Inbox. Turning it off immediately stops us from discovering or enrolling new trips and stops monitoring of currently enrolled trips going forward. You may also close your account at any time. Cancelling does not affect success fees already earned on price drops confirmed before you cancelled. We will not impose any retention offer, additional steps, or charges as a condition of cancelling.
  • Post-Charge Notice and Refund of Surprise Charges: Within 24 hours of each success-fee charge, we email you a receipt identifying the trip, the savings (for an award ticket, the estimated dollar value of the miles recovered), and the fee. If a charge was for a trip you did not intend to enroll — including a trip we discovered automatically through your Connected Inbox — you may request a full refund of that fee within thirty (30) days by contacting support@euclidtravel.ai or using the "Refund this charge" control in your dashboard, and we will refund it to your original payment method without requiring you to dispute it with your bank. This remedy is in addition to, and does not limit, any rights you have under applicable law or your card-network rules.
  • Failed Payments: If a charge fails, Euclid Travel reserves the right to suspend automatic enrollment and cease tracking active trips (flights and hotels) until the balance is resolved.
  • Disputes: We aim to resolve every concern without a chargeback, through the refund path above. Before initiating a chargeback or payment dispute on a success fee, you agree to first contact us at support@euclidtravel.ai and allow ten (10) business days for us to resolve it. Nothing in these Terms limits your right to dispute a charge with your card issuer or under applicable law; we reserve the right to present evidence of your authorization and the services rendered in response to any dispute.

6. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, EUCLID TRAVEL, ITS FOUNDERS, AND AFFILIATES SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOST PROFITS, LOST SAVINGS, OR DISRUPTED TRAVEL PLANS ARISING OUT OF YOUR USE OF THE SERVICES. IN NO EVENT SHALL EUCLID TRAVEL'S TOTAL LIABILITY TO YOU EXCEED THE TOTAL SUCCESS FEES PAID BY YOU TO EUCLID TRAVEL IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM.

7. Dispute Resolution and Binding Arbitration

PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS YOUR LEGAL RIGHTS, INCLUDING YOUR RIGHT TO FILE A LAWSUIT IN COURT.

  • Binding Arbitration: You and Euclid Travel agree that any dispute, claim, or controversy arising out of or relating to these Terms, the Services, or the breach thereof, shall be resolved by mandatory binding arbitration, rather than in court. The Federal Arbitration Act (FAA) governs the interpretation and enforcement of this arbitration agreement.
  • Arbitration Rules: The arbitration will be administered by the American Arbitration Association (AAA) in accordance with its Consumer Arbitration Rules. The arbitrator shall have exclusive authority to resolve any dispute relating to the interpretation, applicability, or enforceability of this binding arbitration agreement.
  • Class Action Waiver: YOU AND EUCLID TRAVEL AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. The arbitrator may not consolidate more than one person's claims and may not preside over any form of a representative or class proceeding.
  • Opt-Out Right: You have the right to opt out of the provisions of this Arbitration Agreement by sending written notice of your decision to opt out to legal@euclidtravel.ai within thirty (30) days after first becoming subject to this Arbitration Agreement. If you opt out, all other parts of these Terms will continue to apply to you.

8. Governing Law and Venue

These Terms shall be governed by and construed in accordance with the laws of the State of New York, without regard to its conflict of law principles. Any legal action or proceeding arising under these Terms that is not subject to arbitration shall be brought exclusively in the state or federal courts located in Kings County, New York, and you hereby consent to the personal jurisdiction and venue therein.

9. Modifications

Changes That Affect Charges. For any change that increases the success-fee percentage or materially changes how or when we charge your payment method, we will notify you by email in advance and obtain your affirmative consent before the change applies to you; if you do not consent, the change will not take effect for you and you may cancel without penalty.

Changes That Expand How We Use Your Data. For any change that expands the purposes for which we use personal information we have already collected from you, including information from a Connected Inbox, we will notify you and obtain your affirmative consent before that change applies to your existing information. Continued use alone is not agreement to such a change.

For all other changes, we will notify you by updating the "Effective Date" at the top of this document or by sending an email notification. Your continued use of the Services following such notification constitutes your acceptance of the updated Terms.

10. Record of Your Consent (E-SIGN)

Your electronic actions — creating an account, accepting these Terms, providing a payment method, and connecting an email inbox to enable automatic enrollment — constitute your electronic signature and your affirmative, express informed consent to these Terms and the charges they authorize, with the same legal effect as a handwritten signature under the federal E-SIGN Act and applicable state law. We retain a timestamped record of each such consent, including the version of these Terms then in effect, the date and time of acceptance, the disclosures shown to you before you connected an inbox, and the identifier of the payment method you authorized. You consent to receive these Terms and all disclosures, charge authorizations, receipts, and notices electronically. This record is evidence of the agreement and of your authorization for each success-fee charge.

11. Scope of Existing Protections

For the avoidance of doubt, the Limitation of Liability (Section 6) and the Binding Arbitration and Class Action Waiver (Section 7) apply in full to all disputes arising out of or relating to inbox syncing (including Gmail), the automatic discovery and enrollment of trips, the charging of success fees on auto-discovered trips or trips booked for others, and our access to or use of Google user data. Because the addition of inbox syncing is a material change to the Services, your continued use after the updated Effective Date constitutes a renewed agreement to arbitrate, and a new thirty (30)-day opt-out period under Section 7 applies, running from that Effective Date.

12. General

  • Assignment: You may not assign these Terms without our prior written consent; any attempted assignment is void. Euclid Travel may assign these Terms, including the agency appointment in Section 1 and the payment authorizations in Section 5, to any successor in connection with a merger, acquisition, reorganization, or sale of assets, and these Terms (including the arbitration agreement in Section 7) bind and inure to the parties' permitted successors and assigns.
  • Severability: If any provision is held invalid or unenforceable, it will be enforced to the maximum extent permissible and the remaining provisions remain in effect. If the Class Action Waiver in Section 7 is found unenforceable as to a claim, that claim proceeds in court (severed from arbitration), but the arbitration agreement and Class Action Waiver remain enforceable as to all other claims.
