Privacy Policy
Last Updated: September 8, 2026
This Privacy Policy explains how Build IO Inc., doing business as Build.io and a subsidiary of ai& Inc. (“Build,” “Company,” “we,” “us,” or “our”), collects, uses, discloses, and otherwise processes information about individuals who visit our websites, create accounts, deploy or manage workloads on our platform, contact us, apply for jobs, or otherwise interact with us online or offline (collectively, the “Services”).
Build IO Inc. is a wholly owned subsidiary of ai& Inc. This Privacy Policy governs the Build.io websites, including build.io and app.build.io. Personal information collected through those websites is handled within the ai& corporate group as described in Section 13 (Japan Notice) and Section 5 (How We Disclose Information).
The Services may include a marketing website, documentation, hosted deployment services, infrastructure and platform tooling, APIs, user accounts, team workspaces, usage dashboards, billing interfaces, support channels, and related offerings.
This Privacy Policy does not apply to information subject to a separate agreement, including any customer agreement, data processing addendum, employment-related notice, or other privacy notice that expressly governs a particular relationship or product.
1. Information We Collect
We may collect information you provide directly to us, including when you create an account, create a team or workspace, request a demo, contact support, sign up for marketing communications, configure deployment settings, connect source repositories or third-party services, submit billing information, or otherwise interact with the Services.
This may include name, email address, phone number, company name, username, account credentials, role or title, billing and transaction details, communications content, support requests, configuration choices, connected service identifiers, and any other information you choose to provide.
We and our service providers may also collect information automatically, including IP address, browser and device information, operating system, usage and log data, account activity, pages viewed, links clicked, approximate location derived from IP address, API activity, deployment events, service metrics, and diagnostic information.
We may receive information from third parties such as payment processors, analytics providers, advertising partners, source code repository providers, identity providers, single sign-on vendors, integration partners, recruiting platforms, and publicly available sources.
Where we collect personal information through a form on our websites, we identify the categories of personal information collected and the purposes for which they will be used at or before the point of collection, and we link to this Privacy Policy from that form.
2. Platform Data, Customer Content, and Operational Telemetry
If you use the platform, Build may process files, configuration data, environment variables, deployment metadata, logs, metrics, traces, support artifacts, prompts or other inputs, outputs, database connection information, and other content submitted to, stored on, routed through, or generated by the Services (“Platform Data”).
We may also collect operational telemetry relating to deployments, builds, runtime performance, scaling behavior, API usage, service health, debugging events, and infrastructure consumption in order to provide, secure, maintain, and improve the Services.
Depending on how the platform is used, Platform Data may include personal information, business information, application content, end-user data, or other sensitive material submitted by you or your users.
Your agreements with us may allocate responsibilities between Build and the customer for such data.
Where Build processes customer data on behalf of business customers, a separate services agreement or data processing addendum may govern that processing.
3. Cookies and Similar Technologies
We and our service providers may use cookies, pixels, local storage, SDKs, session replay tools, and similar technologies to operate and secure the Services, remember preferences, authenticate users, understand usage, debug performance issues, personalize content, and support analytics or marketing activities.
4. How We Use Information
We use information to:
- provide, operate, secure, maintain, and improve the Services;
- create and administer accounts, teams, workspaces, deployments, and integrations;
- process transactions and manage billing, metering, fraud-prevention, and account administration workflows;
- authenticate users and manage access controls;
- monitor uptime, troubleshoot failures, debug issues, and support incident response;
- analyze usage and capacity needs, improve infrastructure efficiency, and develop new features or products;
- respond to support requests and communicate with you about the Services;
- send service, security, legal, marketing, or recruiting communications;
- detect, prevent, and investigate fraud, abuse, security incidents, prohibited activity, and other harmful conduct; and
- comply with legal obligations and enforce agreements, policies, and acceptable use restrictions.
5. How We Disclose Information
We may disclose information:
- to service providers and contractors that perform services on our behalf, such as cloud hosting, infrastructure support, payment processing, customer support tooling, analytics, communications, identity management, security, logging, recruitment, and marketing operations;
- to affiliates and in connection with actual or prospective mergers, acquisitions, financings, asset sales, restructurings, bankruptcies, or similar corporate transactions;
- to comply with applicable law, legal process, or governmental request;
- to enforce our agreements and policies;
- to protect our rights, property, and safety or those of others;
- to detect, prevent, or address fraud, abuse, security incidents, platform misuse, or technical issues;
- at your direction or with your consent, including when you choose to connect third-party integrations or invite users to a workspace; or
- in deidentified, anonymized, or aggregated form that does not reasonably identify you.
6. Advertising and Analytics
We and our service providers use analytics and advertising tools (such as Google Analytics and advertising pixels) to understand website engagement, evaluate demand, and support our marketing efforts. These tools may use cookies or other trackers to collect information about your interactions with our website and other online activities over time and across different services to deliver interest-based or retargeted advertisements. You can learn more about how to opt out of these activities in Section 9 (Your Choices).
7. Data Retention
We retain personal information for as long as reasonably necessary for the purposes described in this Privacy Policy, including to provide and improve the Services, maintain security and fraud-prevention records, preserve logs and backups, comply with legal, tax, accounting, and reporting obligations, resolve disputes, and enforce agreements.
8. Data Security
We use reasonable administrative, technical, and physical safeguards designed to protect personal information. However, no method of transmission over the internet or method of electronic storage is completely secure, and we cannot guarantee absolute security.
9. Your Choices
Opt-Out of Marketing: You may opt out of promotional emails by using the unsubscribe link in the message or contacting us at privacy@build.io. We may still send service-related, transactional, or security communications.
Cookies and AdTech: You may manage cookies through browser settings. Some of our partners may provide their own opt-out mechanisms (e.g., the Google Analytics Opt-out Browser Add-on).
Browser Signals: Our website does not currently respond to automated “Do Not Track” signals. We do honor the Global Privacy Control (GPC) and other opt-out preference signals recognized under applicable law. Where we receive such a signal from your browser or device, we treat it as a request to opt out of the sale or sharing of personal information associated with that browser or device.
10. U.S. State Privacy Rights
Depending on your state of residence, you may have rights to confirm whether we process personal information about you, access it, correct inaccuracies, delete it, obtain a portable copy of certain data, and opt out of targeted advertising, the sale or sharing of personal information, and certain profiling. To exercise these rights, contact us at privacy@build.io. We will not discriminate against you for exercising them. We may need to verify your identity before we act on a request, and you may use an authorized agent where applicable law permits.
Appeals: If we decline to act on your request, you may appeal that decision by contacting us at privacy@build.io with the subject line “Privacy Rights Appeal.” We will respond to an appeal within the period required by applicable law and, if we deny the appeal, we will tell you how to contact the relevant state attorney general.
Notice on Selling and Sharing: We do not sell your personal information to third parties in exchange for monetary compensation. Like many companies, we use third-party services for analytics and advertising that may involve the disclosure of identifiers (such as IP addresses) to those partners. Under certain laws, these activities may be categorized as “selling” or “sharing” of personal information. You may opt out at any time through the “Do Not Sell or Share My Personal Information” link in the footer of our websites, by transmitting a Global Privacy Control signal as described in Section 9 (Your Choices), or by contacting us at privacy@build.io. We do not knowingly sell or share the personal information of consumers under 16 years of age.
11. California Notice
California's “Shine the Light” law (Civil Code Section § 1798.83) permits California residents to request certain information regarding our disclosure of personal information to third parties for their direct marketing purposes. Please contact us at privacy@build.io to inquire further.
12. International Transfers
If you access the Services, your information may be transferred to, stored in, and processed in the United States, Japan, and other countries where privacy laws may differ from those in your jurisdiction. Where required by law, we will use appropriate safeguards for cross-border transfers. Section 13 (Japan Notice) describes how we handle personal information that is subject to Japanese law, including transfers of that information out of Japan.
13. Japan Notice
This Section applies where we handle personal information subject to the Act on the Protection of Personal Information of Japan (Act No. 57 of 2003, as amended) (the “APPI”). If this Section conflicts with any other part of this Privacy Policy, this Section governs for that information.
Business operator. Build IO Inc. is responsible for personal information collected through the Build.io websites. Its parent company, ai& Inc., Queen’s Tower A, 10th Floor, 2-3-1 Minatomirai, Nishi-ku, Yokohama-shi, Kanagawa 220-6010, Japan, acts as the contact point in Japan for that information. The representative of ai& Inc. is David Bennett, Representative Director.
Purposes of use. We use personal information subject to the APPI for the purposes described in Section 4 (How We Use Information). We do not use it beyond those purposes without your consent, except where the APPI permits.
Joint use. We jointly use personal information within our corporate group. The items jointly used are those described in Section 1 (Information We Collect). The parties jointly using them are ai& Inc., aiAND North America Inc., and Build IO Inc. Those parties use them for the purposes described in Section 4 (How We Use Information). The party responsible for their management is ai& Inc., at the address and through the representative identified above.
Transfers outside Japan. Personal information subject to the APPI may be transferred to the United States, where aiAND North America Inc. and Build IO Inc. are located, and to other countries where our service providers operate. Each transfer is made either as part of the joint use described above or to a service provider entrusted with processing on our instruction, in each case under a written agreement requiring the recipient to maintain protections equivalent to those the APPI requires of us. Information about the data protection regime of a recipient country, and about the measures the recipient takes, is available on request at privacy@build.io.
Security control measures. We have adopted a basic policy on the handling of personal data and internal rules governing each stage of its handling; appointed personnel responsible for handling personal data and defined reporting lines; trained our personnel and placed them under confidentiality obligations; controlled physical access to the areas and devices where personal data is handled; and implemented access controls, authentication, and protection against unauthorized external access. Where we handle personal data in a foreign country, we do so having first ascertained that country’s data protection regime.
Requests regarding retained personal data. You may request notification of the purposes of use, disclosure, correction, addition or deletion, cessation of use or erasure, cessation of provision to third parties, or disclosure of records of provision to third parties, in each case to the extent the APPI provides. Send requests to privacy@build.io. We will confirm that the request comes from you or from a representative you have authorized before we respond. We do not charge a fee for these requests.
Complaints. Complaints about our handling of personal information may be sent to privacy@build.io.
14. Children’s Privacy
The Services are not directed to children under 13, and we do not knowingly collect personal information from children under 13.
15. Third-Party Services
The Services may link to or integrate with third-party services. We are not responsible for the privacy practices of those third parties, and we encourage you to review their privacy notices.
16. Changes to this Privacy Policy
We may update this Privacy Policy from time to time. If we do, we will post the updated version and revise the “Last Updated” date above.
