Terms of Service

1. The agreement

These Terms of Service ("Terms") are a binding agreement between Ravinaro LLC, a Wyoming (United States) limited liability company that provides Hailyo ("Hailyo", "we", "us"), and the business that creates or uses a Hailyo account ("Customer", "you"). They cover the Hailyo web app at app.hailyo.com, its API and MCP server, and any related service (the "Service").

You accept these Terms by ticking the box and creating an account, by accepting them when we ask you to, or by using the Service. The person who accepts them confirms that they are at least 18 and are authorised to bind the business they act for. If they are not authorised, they accept these Terms personally.

These Terms include the Privacy Policy, the Acceptable Use Policy, the data processing and sub-processor terms, the Refund Policy and the plan terms on the pricing page, all as in force from time to time. If they conflict, these Terms win, except that the data processing terms win on processing personal data. This version is 2026-10-23.

2. Businesses only

Hailyo is sold only to businesses and professionals acting for their trade, business or profession. It is not offered to consumers, and you confirm you are not using it as one. Because of this, consumer-protection rules that apply only to consumers do not apply to this agreement.

3. Your account

• Give accurate account and billing information and keep it up to date.
• Keep passwords, API keys and two-factor codes secret. You are responsible for everything done through your account, by your team members, and with your API keys.
• Tell us at once at [email protected] if you suspect unauthorised access.
• Workspace owners and admins control who joins a workspace and what they can do. Their actions bind the Customer.

4. Your outreach is your responsibility

Hailyo is a tool. You decide who to contact, what to send and when. You alone are responsible for your outreach, and for following every law and rule that applies to it, including:

• anti-spam and e-marketing laws, such as CAN-SPAM (US), CASL (Canada), PECR (UK), the EU ePrivacy rules as implemented in each member state, and the UAE rules on unsolicited messages;
• data protection laws, such as the GDPR and UK GDPR, the UAE Personal Data Protection Law (Federal Decree-Law 45/2021) and US state privacy laws. That includes having a lawful basis for each person you contact, giving them the information the law requires, and honouring objections and opt-outs;
• the terms of the mailbox providers you connect (such as Google, Microsoft and Zoho) and of any data source you use.

You must complete each campaign's jurisdiction confirmation truthfully, include a working opt-out and your real postal address where the law requires one, and never remove or get around the unsubscribe and suppression features. For personal data in your leads, you are the controller and Hailyo processes it for you, as described in the data processing terms.

5. Acceptable use

You must follow the Acceptable Use Policy. In short, you must not use the Service to: send spam or messages to purchased, rented or scraped lists; send phishing, malware, or false or misleading headers, subjects or sender details; harass anyone or send illegal, hateful or infringing content; contact people who opted out; get around rate limits, suppression lists, sending caps or other safety features; access the Service by automated means outside our API; reverse engineer, copy or resell the Service; or break the law or anyone's rights.

6. AI-written content and lead data

• AI drafts. Hailyo uses AI models to research leads and draft emails. AI can be wrong, out of date or incomplete, even when it cites a source. You must review each email before you approve or send it, and you are responsible for everything you send, including any claim in it.
• Lead data. Leads come from public business information on the open web, found when you ask for them. Public information changes and can be wrong. We do not promise that any lead, email address, verification result or research note is accurate, complete or lawful for you to use. Our only commitments are the bounce credit and first-month guarantee described on the pricing page.
• No guaranteed results. We do not promise any open, reply, meeting, sale or inbox placement rate. Delivery depends on recipients' mail servers, your domains and your content, which we do not control.

7. Connected mailboxes and other services

When you connect a mailbox or another service, you authorise Hailyo to use it on your behalf to send the emails you approve, read replies to them and run the checks the Service needs. Your use of those services is governed by their own terms. We are not responsible for them, for their outages, or for limits or suspensions they impose on your accounts.

8. Fees, renewal and cancellation

• Prices, plans and what each includes are on the pricing page and at checkout. All prices are in US dollars and exclude taxes. You pay any taxes due, other than taxes on our income. Payments are handled by our payment processor.
• Plans are billed in advance, monthly or yearly, and renew automatically for the same period until you cancel. The $1 Test Drive lasts 30 days and then renews to the Starter plan at the price shown at checkout unless you cancel; we remind you 7 days before that first charge.
• You can cancel online in Settings at any time. Cancellation takes effect at the end of the period you have paid for.
• Fees are non-refundable except as stated in the Refund Policy or required by law. Unused leads, sends or other allowances do not carry over unless the pricing page says they do.
• If a payment fails, we may limit the Service after reminding you. If you dispute a valid charge with your bank, we may suspend the account until it is resolved, and you will repay our reasonable costs of collecting amounts you owe.
• We may change prices for future periods with at least 30 days' notice. The change applies from your next renewal, and you can cancel before then.

9. Suspension and termination

We may suspend or limit all or part of the Service immediately, with notice where practical, if: you breach these Terms or the Acceptable Use Policy; your sending causes complaint or bounce rates that put shared sending reputation at risk (for example, complaints above 0.3%); a provider, regulator or court requires it; we reasonably suspect fraud, abuse or a security threat; or you don't pay. We may end this agreement for serious or repeated breach, or with 30 days' notice for any other reason (in that case we refund any prepaid fees for the unused period). You may stop using the Service and delete your account at any time.

After termination you lose access to the Service. Data is deleted as described in the Privacy Policy; export anything you need before then.

10. Your data and our rights

• Your data. You own the data you put into Hailyo and the emails you send ("Customer Data"). You give us a worldwide, non-exclusive licence to host, copy, process and display Customer Data only to provide, secure and support the Service, to follow your instructions, and to meet legal duties. We use it for cross-customer insights only if you opt in.
• Your promises. You confirm you have every right and permission needed for us to process Customer Data as these Terms describe.
• Our property. We and our licensors own the Service, the software, the models we build, the Hailyo brand and everything we provide, other than Customer Data. These Terms give you only a limited, non-exclusive, non-transferable right to use the Service for your internal business while your subscription is active.
• Usage data. We may use data about how the Service is used, aggregated or de-identified so it does not identify you or any person, to run and improve it.
• Feedback. If you send ideas or suggestions, we may use them freely and without payment.

11. Confidentiality

Each party will keep the other's non-public information it receives through the Service confidential and use it only for this agreement, during the agreement and for 3 years after it (and for as long as it remains a trade secret). This does not cover information that is public through no fault of the receiving party, already known to it, independently developed, or that it must disclose by law (after telling the other party where allowed).

12. Beta features and changes to the Service

Features marked beta, preview or early access are provided as they are, may change or end at any time, and are excluded from any commitment we make about the Service. We may change, add or remove features. If we remove a material feature of a paid plan to your disadvantage, we give 30 days' notice and you may cancel and receive a refund of any prepaid fees for the unused period.

13. Disclaimer

To the fullest extent the law allows, the Service, AI output, lead data and everything else we provide are provided "as is" and "as available", without any warranty or condition of any kind, express, implied or statutory, including warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy, and that the Service will be uninterrupted, secure or error-free.

14. Limitation of liability

To the fullest extent the law allows: (a) neither Hailyo nor its members, managers, employees, agents or suppliers is liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for loss of profits, revenue, business, goodwill, data or reputation, or for fines or penalties arising from your outreach, however caused and even if foreseeable; and (b) Hailyo's total liability for all claims arising out of or relating to the Service or these Terms is limited to the fees you paid Hailyo in the 12 months before the event that gave rise to the claim, or US $100 if greater.

These limits apply to every kind of claim, whether in contract, tort (including negligence), statute or otherwise. They do not limit liability that cannot be limited by law, such as liability for fraud, gross negligence or wilful misconduct, or for death or personal injury caused by negligence. The fees reflect this allocation of risk.

15. Your indemnity

You will defend, indemnify and hold harmless Hailyo and its members, managers, employees and agents from and against any claim, demand, investigation, fine, penalty, loss, damage, cost and expense (including reasonable legal fees) arising out of or relating to: your outreach and the messages sent from your account; Customer Data; your breach of these Terms, the Acceptable Use Policy or any law; or your connected accounts. We will tell you about the claim promptly and let you control its defence, but you may not settle it in a way that admits fault for us or binds us without our written consent.

16. Disputes: governing law and the courts of Dubai

• Governing law. These Terms, and any dispute or claim arising out of or relating to them or the Service (including non-contractual ones), are governed by the laws of the Dubai International Financial Centre ("DIFC"), Dubai, United Arab Emirates.
• Exclusive jurisdiction. The Courts of the Dubai International Financial Centre in Dubai, including their Small Claims Tribunal where a claim falls within its limits, have exclusive jurisdiction over any such dispute. Both parties agree to that jurisdiction and give up any objection to it, including that the forum is inconvenient. This is an agreement in writing for the purposes of Article 5(A)(2) of Dubai Law No. 12 of 2004 as amended.
• Our arbitration option. Before or after a claim is filed, Hailyo may choose by written notice to have the dispute finally resolved by arbitration under the Arbitration Rules of the Dubai International Arbitration Centre, by one arbitrator, seated in the DIFC and conducted in English. The award can be enforced in any court with jurisdiction.
• Exceptions. Either party may seek urgent injunctive or other interim relief to protect its intellectual property, confidential information or the security of the Service in any competent court. Hailyo may also bring a claim for unpaid fees in the courts where you are based.
• Individual claims only. To the fullest extent the law allows, claims may be brought only individually, not as a plaintiff or class member in any class, collective or representative proceeding, and each party gives up any right to a jury trial.
• Time limit. Any claim against Hailyo must be brought within 1 year after it arose, or it is permanently barred, unless the law requires a longer period.
• Before starting proceedings, please write to [email protected] so we can try to resolve the matter informally within 30 days.

17. Export controls and sanctions

You confirm that you are not located in, organised under the laws of, or ordinarily resident in a country or region subject to comprehensive US, UN, EU, UK or UAE sanctions, and are not named on, or owned or controlled by anyone named on, any sanctions or restricted-party list (such as the US OFAC Specially Designated Nationals list). You must not use the Service in breach of export-control or sanctions laws. We may suspend or end the Service immediately to comply with them.

18. Changes to these Terms

We may update these Terms. For a material change we give at least 30 days' notice by email or in the app, and ask you to accept the new version when you next sign in. If you don't accept it, you may stop using the Service and cancel; until then, the previous version applies to you. A change never applies to a dispute that arose before it. Non-material changes (such as clarifications) take effect when published.

19. General

• Electronic agreement. You agree to contract, receive notices and keep records electronically. Ticking the box or clicking to accept is your signature. We keep a record of each acceptance (version, time, IP address and browser).
• Notices. We send notices to the email of your account owner or in the app. You send notices to [email protected].
• Force majeure. Neither party is liable for delay or failure caused by events beyond its reasonable control, including failures of internet, hosting, AI or email providers, attacks, natural events, war, or acts of government. This does not excuse payment.
• Assignment. You may not transfer this agreement without our written consent. We may transfer it to an affiliate or in a merger, acquisition or sale of assets.
• Subcontractors. We may use subcontractors and sub-processors, and are responsible for their work under this agreement.
• Publicity. We will not name you or use your logo as a customer without your permission.
• Independent parties. No partnership, agency or employment is created. There are no third-party beneficiaries.
• Whole agreement. These Terms are the entire agreement on their subject and replace any earlier one. Terms in your purchase orders or other documents do not apply.
• Severability and waiver. If a provision is unenforceable, it is limited to the minimum extent needed and the rest stays in force. Not enforcing a right is not a waiver of it.
• Survival. Sections on fees owed, your data, confidentiality, disclaimer, limitation of liability, indemnity, disputes and this section survive the end of the agreement.
• Language. These Terms are written in English. If they are translated, the English version prevails.
