Terms of Service

Airbox is a routing layer that takes email you send to your private addresses and routes its content to large-language-model providers or MCP servers that you connect, then emails you the result. We may modify, suspend, or discontinue features of the Service at any time. Airbox is provided on an “as is” and “as available” basis.

You are responsible for your account, for the security of your login, and for all activity under it. You must provide accurate information and be at least 16 years old (or the age of digital consent where you live). You may not share account credentials or permit others to use your account except as expressly allowed by your plan.

Airbox does not provide AI models. You connect your own provider accounts: your key, your model, your bill. You are responsible for all charges, usage limits, and compliance obligations of the providers you connect, and for having the rights to send them the content you route.

The Service interoperates with third-party LLM providers, MCP servers, payment processors (including Stripe), email infrastructure, and other services we do not control (“Third-Party Services”). Your use of Third-Party Services is governed by their own terms and privacy policies. Airbox does not endorse, warrant, or support Third-Party Services and is not responsible for their availability, security, outputs, actions, or charges. Enabling a Third-Party Service may require us to transmit your content or credentials to that provider solely as needed to operate the Service for you.

You agree not to use Airbox to:

• break the law or infringe others’ rights;
• send spam, malware, or content you have no right to process;
• attempt to bypass security controls, sender allowlists, or rate limits;
• probe, overload, or disrupt the service or its infrastructure.

You are responsible for all content you route through Airbox, including the content of the email you send to your Airbox addresses. If we determine that you have violated these Terms, we may suspend or terminate your account.

Airbox offers a Free tier and paid subscriptions, including Pro and Team. One credit equals one processed email that invokes an LLM, MCP, or other action. Free includes 25 credits per day; Pro includes 1,500 credits per month; Team includes 3,000 credits per month per seat, plus the features described at checkout. Caps and inclusions may change with notice.

Paid plans are billed through Stripe on a recurring basis (monthly or annual) and auto-renew until canceled. You can cancel anytime via the billing portal; cancellation takes effect at the end of the current period. We do not offer refunds, including for partial billing periods, except where required by law. Taxes may apply.

You retain ownership of the content you route. You grant us a limited, worldwide, non-exclusive license to host, process, transmit, and display it solely to operate the Service for you. You represent that you have all rights and consents needed for us to process your content as described in these Terms and our Privacy Policy. We handle your credentials as described on our Security page.

Airbox and its licensors own the Service, including our software, website, documentation, APIs, branding, and usage data we generate from operating the Service (collectively, “Airbox IP”). Except for the limited rights expressly granted in these Terms, no ownership of Airbox IP transfers to you, and we reserve all rights not granted.

Subject to these Terms and your plan, we grant you a limited, non-exclusive, non-transferable, revocable license to access and use the Service for your own internal purposes. Use of our API or SDK is subject to these Terms and our published developer documentation.

Except as expressly permitted, you may not — and may not allow others to:

• sublicense, sell, rent, lease, or otherwise make the Service available to third parties;
• reverse engineer, decompile, disassemble, or otherwise attempt to discover the source code, object code, or underlying structure, ideas, know-how, or algorithms of the Service, except where applicable law prohibits this restriction;
• modify, translate, or create derivative works based on the Service;
• remove or alter any proprietary notices or labels;
• circumvent or disable security, credit limits, sender controls, or other technical restrictions;
• access or use the Service to build a competing product or service, or to copy its features or user interface;
• publish benchmarks or comparative analyses of the Service without our prior written consent;
• use the Service or API in a way that circumvents plan limits, fees, or these Terms.

If we reasonably believe you have violated this section, we may investigate and suspend or terminate your access.

“Confidential Information” means non-public information one party (“Discloser”) discloses to the other (“Recipient”) that is marked confidential or would reasonably be understood as confidential under the circumstances. It does not include information the Recipient can show: (a) is publicly available without breach; (b) was independently developed; (c) was rightfully received from a third party without a duty of confidentiality; or (d) must be disclosed by law, after reasonable notice where permitted.

Each Recipient will use reasonable care to protect the Discloser’s Confidential Information and will use it only as needed to perform under these Terms. Recipient may share Confidential Information with employees, contractors, and professional advisors who need to know and are bound by confidentiality obligations at least as protective as this section.

Our Confidential Information includes non-public information about the Service’s security, architecture, pricing, roadmaps, and performance. Your Confidential Information includes non-public content and credentials you provide, except as we may use it to operate the Service as described in these Terms and our Privacy Policy.

If you provide suggestions, ideas, or other feedback about the Service, you grant Airbox a perpetual, irrevocable, worldwide, royalty-free license to use, modify, and incorporate that feedback without restriction or compensation to you.

Except as expressly stated in these Terms, the Service is provided “as is” and “as available.” To the fullest extent permitted by law, Airbox disclaims all warranties, whether express, implied, or statutory, including implied warranties of merchantability, fitness for a particular purpose, title, non-infringement, and any warranties arising from course of dealing or usage of trade. We do not warrant that the Service will be uninterrupted, error-free, secure, or meet your requirements. We are not responsible for the accuracy, quality, or legality of outputs from Third-Party Services, including AI-generated responses.

By you. You will defend, indemnify, and hold harmless Airbox and its officers, directors, employees, contractors, and agents from and against any third-party claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys’ fees) arising out of or related to: (a) your content or use of the Service; (b) your breach of these Terms or applicable law; (c) your use of Third-Party Services in connection with Airbox; or (d) any dispute between you and a third party relating to content you routed through the Service.

By Airbox. Airbox will make a commercially reasonable effort to defend you against any third-party claim, damages, losses, and liabilities alleging that the Service itself, as provided by Airbox and used in accordance with these Terms, directly infringes a U.S. patent, copyright, or trademark, and will indemnify you for damages and costs finally awarded against you in any such claim, provided we are promptly notified, given sole control of the defense and settlement, and receive reasonable cooperation. If the Service is or is likely to become infringing, we may modify the Service, obtain a license, or terminate your access and refund any prepaid, unused subscription fees for the terminated portion. This section states our sole obligation and your exclusive remedy for infringement claims regarding the Service.

Procedure. The indemnified party must promptly notify the indemnifying party of any claim, allow the indemnifying party to control the defense and settlement, and provide reasonable assistance. The indemnifying party will not settle any claim in a way that admits fault or imposes obligations on the indemnified party without prior written consent.

To the fullest extent permitted by law, neither Airbox nor its suppliers, affiliates, contractors, or employees will be liable for any indirect, incidental, special, consequential, or exemplary damages, including lost profits, lost revenue, loss of data, business interruption, or replacement costs, arising out of or related to these Terms or the Service, even if we have been advised of the possibility of such damages.

Our total liability for all claims arising out of or related to these Terms or the Service, whether in contract, tort, or otherwise, will not exceed the greater of (a) the fees you paid to Airbox in the twelve (12) months before the event giving rise to the claim, or (b) USD 100. Multiple claims will not enlarge this limit. These limitations are fundamental to the bargain between us and apply even if any remedy fails of its essential purpose.

Some jurisdictions do not allow certain exclusions or limitations. In those jurisdictions, our liability is limited to the maximum extent permitted by law.

Term. These Terms begin when you first accept them or create an account and continue while you use the Service or maintain a paid subscription, unless terminated as described below.

Termination by you. You may stop using Airbox and delete your account at any time. Canceling a paid subscription stops renewal at the end of the current billing period.

Termination or suspension by us. We may suspend or terminate your access immediately if you materially breach these Terms, fail to pay fees when due, create risk or possible legal exposure for us or others, or if we are required to do so by law. Where a breach is curable, we may provide notice and a reasonable opportunity to cure before termination. Termination is not our only remedy for breach.

Effect of termination. Upon termination, your right to use the Service ends. Termination does not relieve you of payment obligations accrued before termination. You may export or delete your data as described in our Privacy Policy. After any applicable retention period, we may delete your account data. Sections that by their nature should survive termination will survive, including your content grants, Airbox intellectual property, license restrictions, confidentiality, feedback, payment obligations, disclaimers, indemnification, limitation of liability, governing law, and dispute resolution.

We are not liable for any delay or failure to perform resulting from events outside our reasonable control, including acts of God, natural disasters, war, terrorism, labor disputes, internet or utility failures, third-party service outages, or denial-of-service attacks.

You may not use the Service if you are located in, ordinarily resident in, or organized under the laws of a country or region subject to comprehensive U.S. trade sanctions, or if you are a prohibited party under applicable export-control or sanctions laws. You agree to comply with all applicable import and export laws in your use of the Service.

Entire agreement. These Terms, together with our Privacy Policy and Security page, are the entire agreement between you and Airbox regarding the Service and supersede prior agreements on that subject.

Changes. We may update these Terms from time to time. Material changes will be notified and the “Last updated” date revised. Continued use after changes take effect constitutes acceptance.

Assignment. You may not assign or transfer these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, corporate reorganization, or sale of assets, or to an affiliate.

Severability. If any provision is held invalid or unenforceable, the remaining provisions remain in full force and effect.

No waiver. Our failure to enforce any provision is not a waiver of that provision or any other provision.

Governing law & disputes. These Terms are governed by the laws of the State of Delaware, United States, without regard to conflict-of-law rules. Except where prohibited by law, you and Airbox agree to the exclusive jurisdiction of the state and federal courts located in Delaware for any dispute arising out of or relating to these Terms or the Service. Either party may seek injunctive relief in any court of competent jurisdiction to prevent misuse of the Service or infringement of intellectual property rights.
