1. Agreement and who we are

These Terms of Service (“Terms”) govern your use of Brello, including the website at brello.app, the dashboard, our APIs, and our software development kits (“SDKs”) (together, the “Service”).

The Service is operated by Gyuyeon Lee, doing business as Brello, an individual based in the Republic of Korea (“Brello”, “we”, “us”). By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

If you use the Service on behalf of a company or other organization, you confirm that you have authority to bind it to these Terms, and “you” includes that organization.

Definitions

• Provider: a third-party AI API provider you connect to Brello, such as OpenAI, Anthropic, or Google.
• Customer Data: data you or your applications send to the Service, including usage events, cost data, and connected credentials.
• End User: a user of your own application whose identifier you send to the Service.

2. Beta service

The Service is currently in beta. During the beta:

• Features may be added, changed, or removed at any time without notice.
• The Service may be unavailable, slow, or contain errors. We do not offer any uptime commitment or service level agreement.
• We may need to reset, migrate, or delete Customer Data, including usage history. We will try to give advance notice when we can, but we cannot guarantee it.
• Features marked as free during the beta may become paid features when the Service launches publicly. We will tell you before that happens, and you will not be charged unless you choose a paid plan.

You should not rely on the Service during the beta as your only way to monitor or control AI API spending.

3. Accounts

• Eligibility. You must be at least 18 years old to use the Service.
• Sign-in. You can sign in with GitHub, Google, or an email address. When you sign in through GitHub or Google, their own terms also apply to that sign-in.
• Accurate information. You agree to give accurate account information and keep it up to date.
• One person per account. Each account is for one individual. You may not share your login with others. If more people need access, each should create their own account.
• Security. You are responsible for keeping your login and any Brello API keys or SDK keys secure, and for all activity under your account. Tell us right away at hello@brello.app if you think your account or keys have been compromised.

4. Your data and connected keys

You own your data. You keep all rights to Customer Data. You give Brello a limited permission to store, process, and display Customer Data only as needed to run, secure, and improve the Service for you.

Connected Provider keys. To show your spending, you may connect keys that let Brello read usage and billing data from your Providers. Where the feature is offered, you may also register backup keys for Brello to use only in the situations you configure. For all connected keys:

• We encrypt them at rest and use them only for the purposes you set up.
• We recommend using keys with the narrowest permissions a Provider allows, such as read-only usage access.
• You can remove a key at any time, and we will stop using it and delete it from our systems.
• You confirm you are allowed to connect each key under the Provider’s terms.

What the SDK sends. The Brello SDK sends usage metadata only: for example, the model, token counts, cost, timestamps, and the End User identifier you choose to pass. It never sends the content of your prompts or the Provider’s responses.

End User identifiers. You decide what identifier to send for each End User. We recommend an internal ID or a hashed value rather than an email address or other personal information. You are responsible for having a lawful basis and any required notice to your End Users for sending these identifiers.

Aggregated data. We may create aggregated and de-identified statistics from usage across the Service, for example average spend by model or team size. These statistics never identify you, your company, or your End Users, and we may use them to improve and market the Service.

Our Privacy Policy explains in more detail how we handle personal information.

5. Acceptable use

You agree not to:

• Connect keys or accounts you do not own or are not authorized to use.
• Use the Service in a way that breaks any law or any Provider’s terms of service.
• Try to access another user’s account, projects, or data, or probe or test the Service for vulnerabilities without our written permission.
• Send malicious code, or send data designed to disrupt or overload the Service.
• Send prompt or response content, or sensitive personal information such as government IDs or payment card numbers, through the SDK fields meant for metadata.
• Resell, sublicense, or provide the Service to third parties as your own product without our written permission.
• Reverse engineer the Service, except for any SDK we publish as open source under its own license.

If you find a security issue, please report it to hello@brello.app. We appreciate good-faith reports.

6. Fees and billing

• Plans. Some features are free and some require a paid subscription. Current plans and prices are listed on our pricing page.
• Payment processor. Paid subscriptions are sold through Paddle.com, which acts as the merchant of record and reseller. Paddle handles payment, invoicing, and sales tax or VAT, and its own buyer terms also apply to your purchase.
• Renewal. Subscriptions renew automatically at the end of each billing period until you cancel. You can cancel at any time from your account settings, and you keep access until the end of the period you paid for.
• Refunds. If you are not satisfied, you can request a full refund within 14 days of your first payment for a plan by emailing gyeon@brello.app. After that, payments are non-refundable, except where the law requires otherwise.
• Price changes. We will give you at least 30 days’ notice before a price change affects your subscription. The new price applies from your next renewal after the notice period.
• Provider costs are yours. Brello fees do not include what your Providers charge you. You remain fully responsible for all charges from your Providers.

7. Accuracy of cost data and alerts

Brello helps you see and understand your AI API spending, but it is not your Provider’s bill.

• Pending amounts are estimates. Costs shown as “pending” are calculated from SDK events before your Provider’s billing data is available. They may differ from the final amount.
• Confirmed amounts come from Providers. Costs shown as “confirmed” are based on billing data your Providers make available to us. If a Provider’s data is late, incomplete, or wrong, our numbers will be too.
• Per-End-User costs are estimates. Providers do not report costs by End User, so per-End-User figures are calculated from SDK events and may not add up exactly to your confirmed total.
• Forecasts are projections. Forecasts are based on past usage and are not a promise of future costs.
• Alerts are best effort. We try to detect unusual usage and send alerts quickly, but alerts can be delayed, missed, or sent in error. This can happen, for example, when a Provider’s data is delayed, when the SDK is not installed or configured correctly, or when the Service is unavailable.

Your Provider’s invoice is always the final record of what you owe. You are responsible for setting spending limits and monitoring your accounts directly with your Providers.

8. Disclaimers and limitation of liability

Disclaimer. The Service is provided “as is” and “as available”. To the fullest extent the law allows, we disclaim all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not promise that the Service will be uninterrupted, error-free, or that it will detect every unusual charge, leaked key, or misuse.

No liability for Provider charges. Brello is not responsible for any amount charged by your Providers, including charges caused by leaked or misused keys, unusual usage, or abuse by your End Users, whether or not the Service detected it or sent an alert.

Limitation of liability. To the fullest extent the law allows:

• Brello will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for lost profits, revenue, data, or goodwill.
• Brello’s total liability for all claims relating to the Service is limited to the amount you paid Brello for the Service in the 12 months before the event giving rise to the claim. If you have not paid anything, Brello’s total liability is zero.

These limits apply even if we were told such damages were possible. Some jurisdictions do not allow certain limitations, so some of them may not apply to you. Nothing in these Terms limits liability that cannot be limited by law, such as liability for intentional misconduct.

Indemnity. You agree to cover Brello for claims, losses, and costs arising from your violation of these Terms or of any law or Provider’s terms, or from data you send to the Service.

9. Suspension and termination

• By you. You can stop using the Service and delete your account at any time from your account settings.
• By us. We may suspend or close your account if you break these Terms, if your use creates a security risk or harms the Service or other users, or if the law requires it. Where reasonable, we will tell you first and give you a chance to fix the issue. We may also discontinue the Service, in which case we will give you at least 30 days’ notice and refund any prepaid fees for the unused period.
• What happens to your data. When your account is deleted or closed, we immediately stop using and delete your connected Provider keys. Other Customer Data is kept for 30 days so you can recover or export it, and is then permanently deleted. Backups may take a short additional time to expire, and aggregated, de-identified statistics described in Section 4 are not deleted.
• What survives. Sections 4 (aggregated data), 7, 8, and 10, and any unpaid fees, continue to apply after termination.

10. Changes, governing law, and contact

• Changes to these Terms. We may update these Terms from time to time. For material changes, we will email you at least 14 days before they take effect. Other changes take effect when we post them on this page, with the updated date at the top. If you keep using the Service after changes take effect, you accept the new Terms.
• Governing law. These Terms are governed by the laws of the Republic of Korea, without regard to conflict of law rules.
• Disputes. Any dispute arising from these Terms or the Service will be resolved exclusively in the Seoul Central District Court, Republic of Korea. This does not take away any rights you have under the mandatory consumer laws of the country where you live.
• Entire agreement. These Terms, together with our Privacy Policy, are the entire agreement between you and Brello about the Service. If any part is found unenforceable, the rest stays in effect. If we do not enforce a right, we have not waived it.
• Assignment. You may not transfer these Terms without our consent. We may transfer them, for example to a company we form to operate the Service, and we will tell you if we do.
• Contact. Questions about these Terms: hello@brello.app.
