Terms of use.

Last updated: September 27, 2026

1. Acceptance of these terms

These terms apply to signing up for and using Hey Will. In them, "you" means the company or professional that signs up for Hey Will, and "we" and "us" mean i9Store USA LLC.

By signing up for or using Hey Will, you accept these terms. Anyone who accepts them on behalf of a company represents that they have the authority to do so.

When these terms change, we publish the new version on this page, with the date. If the change is material, we also notify customers by email. How we handle personal data is covered in the privacy notice.

2. What Hey Will is

Hey Will is a product of i9Store USA LLC (i9Store.com), a Florida company, USA, located at 20815 NE 16th Ave, STE B33, Miami, FL 33179, USA.

Hey Will is an AI that works for companies in the systems they already use. You connect your systems, such as your ERP, email, CRM, banks through Open Finance (regulated by Brazil’s Central Bank) and store, and Will reads and acts in them according to what you set up. Will works on the web, on the Mac and on iPhone.

3. Signing up for the service

Hey Will is for companies and professionals, for use at work, and isn’t directed at anyone under 18.

Your plan and its conditions are set out in the commercial proposal you accept. To sign up, write to heywill@i9store.com.

4. Accounts and access

You manage the accounts of the people on your team and set each person’s permissions: what each person can see and ask Will to do. Sign-in goes through an authentication provider.

Each person should keep their own access secure. If you learn of any unauthorized access, let us know at heywill@i9store.com.

5. Acceptable use

Hey Will must be used lawfully and in line with these terms. You may not:

• Use Hey Will for unlawful purposes.
• Misuse connected systems, for example to access systems, accounts or data without authorization.
• Try to get around or break Hey Will’s security, or access other companies’ data.

6. Approvals and responsibility for actions

You set up what Will can do: what it does on its own and what it brings to a person to decide. Will acts within that setup.

Payments are always made by a person: Will never makes a payment on its own. Anything you mark as sensitive also always goes through a person.

You are responsible for the decisions you make and the actions you authorize, including those Will takes on its own within the setup you defined. Every action Will takes gets a receipt: who asked, what was done, in which system, when and based on which source.

7. Your company’s data and connected systems

You connect your systems to Will with an authorization given once, at the start, item by item. You can revoke any item at any time.

By connecting a system, you represent that you have the authorizations needed to do so and that the data in it is processed lawfully.

Under the LGPD (Brazil’s data protection law), you are the controller of the personal data in these systems, and i9Store USA LLC is the processor: it handles that data on your behalf and follows your instructions. A data processing agreement is available on request at heywill@i9store.com. Hey Will doesn’t use customer companies’ data to train AI models. The details are in the privacy notice.

8. Third-party services

The systems you connect, such as your ERP, email, bank and marketplaces, are third-party services and remain subject to each provider’s own terms.

Each integration’s availability depends on the provider of that system. If the provider changes or cuts off access, the integration may change or stop working.

9. Pricing and payment

Hey Will plans are custom. Pricing, billing and taxes follow the commercial proposal you accept.

10. Availability and changes to the service

We make reasonable efforts to keep Hey Will available. The service may be unavailable during maintenance windows.

Hey Will changes over time: features and integrations may change. When a change is material, we let customers know.

11. Intellectual property and confidentiality

Hey Will belongs to i9Store USA LLC, including the software, the brand and the service materials. The contract gives you the right to use Hey Will while it is in effect, without transferring ownership.

Your company’s data is yours. So are the results Will produces for you, such as reports, answers and documents.

Each party keeps confidential the information it receives from the other and uses it only to perform the contract, except when the law or an authority requires disclosure.

12. Limitation of liability

i9Store USA LLC is not liable for indirect or consequential damages. i9Store USA LLC’s total liability is limited to the amount you paid for Hey Will in the 12 months before the event that caused the damage.

These limits don’t apply where the law doesn’t allow liability to be limited.

13. Suspension and termination

We may suspend or terminate access to Hey Will in case of:

• A breach of these terms.
• Non-payment.
• A security risk.

You can end the contract under the conditions of the commercial proposal.

When the contract ends, you have 30 days to export your data. After that period, it is deleted or anonymized within 90 days, except for anything the law requires us to keep. See the privacy notice.

14. Governing law and jurisdiction

These terms are governed by the laws of the State of Florida, USA. Disputes about them are resolved in the courts of Miami-Dade County, Florida.

This doesn’t set aside the mandatory Brazilian rules that apply to customers in Brazil, including the LGPD, or any right the law gives you to bring a claim where you are domiciled.

15. Contact

For questions about these terms, write to heywill@i9store.com. We reply within 1 business day.
