Terms of Service
Version 2026-09-28 · Effective September 28, 2026
These Terms of Service ("Terms") are an agreement between you and DoubleX ("DoubleX", "we", "us") for the use of the DoubleX platform at infra.doublex.ai, its console, API, MCP server, command-line tool and the apps it hosts (together, the "Service"). By creating an account, checking the acceptance box or using the Service, you agree to these Terms and to the Privacy Policy. If you do not agree, do not use the Service.
If you accept these Terms on behalf of a company or other organization, you confirm that you have authority to bind it, and "you" means that organization.
1. What the Service is
DoubleX is infrastructure for data, business intelligence and AI. Your AI assistant or coding agent (for example Claude, ChatGPT or another tool you choose) connects to the Service through MCP or the API and, on your behalf, loads data, models it, defines metrics and publishes apps on a web address. DoubleX stores and runs what your AI builds: the data lake, the query engine, the semantic layer, app hosting, addresses, sign-in for your end users and the database.
DoubleX does not provide its own chat or assistant, and does not provide an AI model. Any AI feature inside an app you publish uses your own provider account and key ("bring your own key"). Your relationship with that provider is governed by your agreement with it.
2. Eligibility and accounts
You must be at least 18 years old and able to enter into a binding contract. The Service is intended for professional and business use.
You are responsible for your account, for the accuracy of the information you give us and for everything done with your credentials, including personal access tokens, MCP connections and API keys. Keep them secret, revoke the ones you no longer use and tell us at once at legal@doublex.ai if you suspect unauthorized access.
Actions taken by an AI agent or tool you connected to the Service are actions taken by you. Changes to protected environments go through change sets and your approval; approving a change set is your decision.
3. Your content and your data
"Customer Data" means the data, files, code, models, metric definitions, apps and other content that you or your agents send to the Service, and the data of your end users.
You keep all rights to Customer Data. You grant DoubleX a worldwide, non-exclusive, royalty-free license to host, copy, process, transmit and display Customer Data only as needed to provide, secure and support the Service for you, and to comply with law.
You are responsible for Customer Data: that you have the right to upload and process it, that you have a legal basis and have informed the people it relates to, and that your apps comply with the laws that apply to them. For Customer Data, you are the controller and DoubleX acts as your processor, under section 4.
DoubleX does not sell Customer Data, does not use it to train AI models and does not use it for advertising.
4. Data processing terms
When DoubleX processes personal data contained in Customer Data, it does so as a processor ("operador" under Brazil's LGPD; "processor" under the GDPR and similar laws) on your behalf, and:
- processes it only to provide the Service, following your instructions as expressed through your use of the Service, your configuration and these Terms;
- ensures that people with access to it are bound by confidentiality;
- applies technical and organizational security measures, including encryption in transit and at rest, logical isolation between customers with a catalog, credentials and policies per project, scoped tokens, secrets referenced by name and SQL validated before execution;
- uses only the subprocessors listed in the Privacy Policy, gives notice of new subprocessors by updating that list at least 15 days before the change, and lets you object by closing your account;
- stores Customer Data in Google Cloud's São Paulo, Brazil region (
southamerica-east1), unless you choose another region offered for a project; - helps you, as far as the Service allows, to respond to requests from data subjects and authorities; requests that reach us about Customer Data will be forwarded to you;
- notifies you without undue delay after becoming aware of a security incident affecting Customer Data;
- deletes Customer Data when you delete a project or your account, as described in section 13.
5. Acceptable use
You may not use the Service, or let anyone use it, to:
- break the law or infringe the rights of others, including intellectual property, privacy and data protection rights;
- host or distribute malware, phishing pages, spam, or content that is illegal, sexually exploits minors, incites violence or promotes terrorism;
- impersonate a person, brand or organization, including through an app address or custom domain that suggests an affiliation that does not exist;
- mine cryptocurrency, run open proxies, or run workloads unrelated to data, BI, AI or apps built on them;
- attack, probe or scan the Service or other customers, try to access data that is not yours, or bypass isolation, quotas, plan limits, rate limits or billing;
- attempt to manipulate DoubleX systems or other customers' agents through prompt injection or similar techniques;
- resell or offer the Service as a standalone product without our written agreement.
We may remove content, block an address, stop an app or suspend an account that violates this section, preferably with prior notice, and without notice when the risk to others, to the Service or to the law requires it. Report abuse to legal@doublex.ai.
6. Apps, end users and third-party services
You are responsible for the apps you publish and for your relationship with the end users you invite to them, including informing them about how their data is processed. End users are not parties to these Terms; they should contact you, not DoubleX, about your app and their data in it.
The Service works with third-party services such as your AI provider, your data sources and your domain registrar. We are not responsible for third-party services, their availability or their terms.
7. AI output and actions of your agent
The Service executes SQL, pipelines and deploys that your AI agent writes or proposes. AI output can be wrong, incomplete or unexpected, even when the Service shows the SQL and the metric that produced a number. You are responsible for reviewing and approving what your agent does and for decisions you make based on results. DoubleX does not guarantee the accuracy of AI output or of queries written by your agent. The change history and approvals recorded by the Service are the record of what was done and by whom.
8. App addresses and custom domains
An app address (for example <label>.apps.doublex.ai) is a label that DoubleX assigns to your organization for use with the Service; it is not a domain you own. A label that has been published never passes to another organization. We may refuse, remove or change a label that violates section 5, infringes a trademark, is used for phishing, or that we are ordered to remove by a court or competent authority.
For a custom domain, you must control the domain and keep the DNS records we ask for. When you remove a domain or delete a project, deleting the DNS records that point to the Service is your responsibility. If two customers claim the same hostname, we decide based on proof of control of the domain (DNS record, registry data or documents) and may remove it from a project when a third party proves ownership or a court orders it.
9. Plans, prices and payment
The Service is offered in a free plan and paid plans described at infra.doublex.ai. Prices are in US dollars unless shown otherwise, and do not include taxes, which are added where required.
Paid plans are billed in advance, monthly, through our payment processor (Stripe), and renew automatically until cancelled. By subscribing, you authorize recurring charges to your payment method. You can cancel at any time in the billing page of the console; cancellation takes effect at the end of the current billing period, and you keep the paid plan until then. Except where the law requires otherwise, payments are not refundable and there are no refunds for partial periods.
We may change prices or plans with at least 30 days' notice. The change applies from your next billing period; if you do not agree, you may cancel before it.
Plan limits (projects, storage, compute, requests and others) are enforced by the Service. If you exceed a limit, new operations may be refused until you upgrade or reduce use.
10. Late payment and suspension
If a payment fails, we will notify you and try again. If the amount remains unpaid for 14 days, we may suspend paid features and apps of the affected account. During suspension your data is kept and not deleted for at least 30 days, and access is restored after payment. After that period, we may downgrade the account to the free plan or close it under section 13, with prior notice.
11. Availability and changes to the Service
We work to keep the Service available and secure, but it is provided without a service level agreement unless one is agreed in writing. Maintenance, incidents at our providers and events outside our control may cause interruptions. We may change, add or remove features; if we remove a material feature of a paid plan, we will give reasonable notice.
12. DoubleX's intellectual property and feedback
The Service, its software, documentation, templates and brands belong to DoubleX or its licensors. We grant you a limited, non-exclusive, non-transferable right to use the Service under these Terms. Templates and code the Service generates into your repository are yours to use and modify. If you send us suggestions, we may use them without obligation to you.
13. Term, termination and deletion
These Terms apply while you use the Service. You may stop using it and delete your projects or account at any time. We may terminate these Terms for material breach not remedied within 15 days of notice, immediately for serious violations of section 5, or with 30 days' notice for any other reason.
When a project is deleted, it immediately stops accepting changes and its resources (apps, data in the lake, end-user accounts, secrets) are deleted within 7 days. Backups expire on their own cycle, up to 35 days. We keep audit records and billing and tax records for as long as the law requires or as needed to exercise or defend rights. Before deleting, export what you want to keep; your agent can read your data through the Service while the project is active.
Sections 3 (license for retention required by law), 7, 12, 14, 15, 16 and 18 survive termination.
14. Disclaimer
To the extent permitted by law, the Service is provided "as is" and "as available". DoubleX disclaims implied warranties of merchantability, fitness for a particular purpose and non-infringement, and does not warrant that the Service will be uninterrupted, error-free or that results will be accurate.
15. Limitation of liability
To the extent permitted by law: (a) neither party is liable for indirect, incidental, special or consequential damages, or for lost profits, revenue or data, even if advised of their possibility; and (b) DoubleX's total liability arising out of or related to these Terms is limited to the amounts you paid for the Service in the 12 months before the event, or US$ 100 if you did not pay.
These limits do not apply to liability that cannot be limited by law, including for fraud or willful misconduct, and do not reduce the rights of consumers under mandatory law.
16. Indemnity
You will defend and indemnify DoubleX against third-party claims arising from Customer Data, your apps or your violation of these Terms or of the law, and pay the resulting damages and reasonable costs, provided we notify you promptly and let you control the defense.
17. Changes to these Terms
We may update these Terms. We will announce material changes at least 30 days in advance, by email or in the console, and ask you to accept the new version. Changes required by law or for security may take effect sooner. The version and date are at the top of this page.
18. Governing law and disputes
These Terms are governed by the laws of the Federative Republic of Brazil. The courts of the district of DoubleX's registered office have jurisdiction, except that consumers may bring proceedings in the courts of their own domicile and keep the protection of mandatory consumer law of their country of residence. Before going to court, the parties will try to resolve the dispute in good faith for 30 days after written notice.
19. General
These Terms, the Privacy Policy and any order or agreement signed with DoubleX are the entire agreement on the Service. If a provision is invalid, the rest remains in effect. Not enforcing a right is not a waiver. You may not assign these Terms without our consent; we may assign them to a successor in a merger, acquisition or sale of assets. You must comply with export control and sanctions laws that apply to your use. These Terms are available in English and Portuguese; both versions are equally valid, and in case of conflict for a customer in Brazil the Portuguese version prevails.
