Last updated: October 11, 2026

Draft: the operator's legal details are still to be published. Until then this text is provisional and may change.

In short

  • We collect what we need to run CubicBuilds: your email (and your Discord profile if you sign in with Discord), your organization, what you type and upload, what you generate, and security data such as your IP address.
  • No advertising, no third-party analytics and no trackers. We do not sell your data.
  • Your requests go to our AI provider, Anthropic, to generate the builds. They are not used to train its models.
  • Data is stored in the European Union. We keep it while your account exists and delete it within 30 days when you ask.
  • Write to [email protected] to access, correct, export or delete your data.

This summary does not replace the full text.

01Who is responsible for your data

Pending publication, the operator of CubicBuilds, decides how and why your personal data is used. Data-protection law calls this the "controller".

Privacy contact
[email protected]

This policy covers cubicbuilds.com, the app at app.cubicbuilds.com and our support and community channels. We have not appointed a data protection officer, because the law does not require one for an operation of our size: [email protected] is the channel, and the area in charge, for every privacy request.

02The data we collect

Your email address is required to have an account: without it we cannot sign you in. Everything else is either optional or results from using the Service.

CategoryWhat it includesWhere it comes from
AccountEmail address, display name (your Discord name, or the part of your email before the @), language, account status and dates.You; Discord if you sign in with it

We do not collect payment card numbers, precise location or advertising identifiers, and we do not ask for special categories of data such as health, beliefs or biometrics. Please keep personal data about other people, and sensitive information, out of your prompts and files.

03What we use it for, and on what basis

Improve the Service: the shared style library, quality checks and aggregate figuresStyle options, usageOur legitimate interest in improving the Service
Comply with the law and defend legal claimsWhat each case requiresA legal obligation; our legitimate interest in defending our rights

We do not send marketing emails. If we ever do, it will be only with your consent, and every message will let you unsubscribe.

In countries where the law takes your authorization as the basis for processing, such as Colombia and Argentina, you give it when you create your account and accept this policy, and you can withdraw it by asking us to delete your account.

We do not take decisions that produce legal or similarly significant effects on you by automated means alone. Limits on repeated attempts are applied automatically: if one affects you unfairly, write to us and a person will review it.

04How the AI handles your requests

To generate a build we send your request to Anthropic, the company that provides the Claude AI models. The request contains the text you wrote, the reference images and areas you attached, recent messages of the conversation and the context of the project: its name, your rules and notes, file names and style choices. We do not attach your name, your email address or your account identifiers to it.

  • Anthropic processes this content on our behalf, to return the result. Under its commercial terms it may not use it to train its models.
  • Anthropic deletes requests and results from its systems within 30 days by default. Content that it flags as breaking its usage policy may be kept longer, as its retention documentation describes.
  • When the AI looks for visual references it may send a short search phrase, written by the AI, to Wikipedia and Wikimedia Commons. It contains no personal data.
  • Anything you type into a prompt becomes part of the request, so do not include personal data.

05Who receives your data

We share personal data only with the providers that help us run the Service, and only what each one needs.

ProviderWhat it doesData involvedWhere
Hetzner Online GmbHHosts our servers: database, files and applicationsAll the data described in this policyEuropean Union (Hetzner data centres in Germany or Finland)
Cloudflare, Inc.Network, DNS and protection against attacks: traffic to the Service passes through itYour IP address and the requests you make, in transitWorldwide network; company based in the United States
Anthropic, PBCGenerates the builds, as described aboveYour requests and the context of the projectUnited States
PayNow Services, Inc.Sells and charges purchases as merchant of record, under its own privacy policyName, email, billing and payment detailsUnited States
Discord Inc.Sign-in with Discord, if you choose it, and our community server, under its own privacy policyYour Discord account detailsUnited States
Wikimedia FoundationReference searchA short search phrase, with no personal dataUnited States

Sign-in emails are sent from our own mail server, not through an email marketing company.

  • Your organization. Members see the organization's projects according to their role, and every member sees the name, email address, profile image and role of the others.
  • Authorities, when the law requires it and after checking that the request is valid.
  • A successor, if the Service is transferred to another operator, under the same commitments as this policy.

We do not sell your personal data, and we do not share it for advertising.

06International transfers

Your data is stored on servers in the European Union. The operator is established in Pending publication and its team accesses the data from there to run and support the Service, and some of the providers listed above are in the United States.

When personal data leaves the European Economic Area, the United Kingdom or another country that restricts transfers, we rely on the mechanisms the law accepts, such as a decision that the destination offers adequate protection or the European Commission's standard contractual clauses included in our agreements with those providers. Write to [email protected] if you want more detail or a copy of the safeguards.

07How long we keep it

We keep your data while your account or your organization exists, because we need it to provide the Service. When you ask us to delete it, we erase it or make it anonymous within 30 days of confirming that the request is yours.

DataHow long
Account, organizations, projects, builds, files and generation logsWhile the account or the organization exists; erased within 30 days of your request
Projects you delete in the appRemoved from your workspace at once. To have them permanently erased from our systems, write to [email protected]: we do it within 30 days
SessionsA session stops working after 7 days without use, and after 30 days at most. Its record, with your IP address and browser type, is kept while your account exists
Sign-in codesValid for 10 minutes; we store them only as a hash
InvitationsWhile the organization exists
Counters that limit repeated attemptsFrom 60 seconds to 24 hours
Activity records and purchase recordsWhile the organization exists, and afterwards only as long as the law requires or as we need them to resolve disputes
Technical logs and the messages you send usFor as long as we need them to operate and support the Service
Backup copies of the databaseUp to 14 copies, one made before each update of the Service. Data we erased can remain in a copy until it is replaced, which can take more than 30 days
Content sent to our AI providerUp to 30 days in its systems, as described above

PayNow keeps payment records for the time its own policy states.

08Your rights

Wherever you live, you can ask us to:

  • Access your personal data and receive a copy.
  • Correct data that is wrong or incomplete.
  • Delete your data or your account.
  • Restrict how we use it while a question is being resolved.
  • Receive the data you gave us in a structured, commonly used format (portability).
  • Withdraw your consent or authorization, where we rely on it.

You can object at any time to uses based on our legitimate interests, including the showcase of builds in our gallery and marketing. Write to [email protected] or [email protected] and we will stop, unless we have compelling reasons that the law recognizes.

To use any of these rights, write to [email protected] from the email address of your account, so that we know the request is yours. It costs nothing. We answer within one month, or sooner where the law of your country says so (see below); if a request is complex we may need up to two more months, and we will tell you why. Today our team handles these requests by email: the app does not yet have self-service tools to export or delete an account.

If you are not satisfied with our answer, you can complain to the data-protection authority of your country (see below). We would appreciate the chance to resolve it first.

09Information for specific countries

European Economic Area, United Kingdom and Switzerland

You can complain to the supervisory authority of the country where you live or work. The European Data Protection Board keeps the list of EU authorities, and in the United Kingdom the regulator is at ico.org.uk.

Colombia

Your rights are those of Law 1581 of 2012: to know, update, rectify and delete your data, to ask for proof of your authorization, to be told how your data has been used, and to revoke the authorization. We answer queries within 10 business days and claims within 15 business days, each extendable once as the law provides. After making a claim to us you can go to the Superintendencia de Industria y Comercio (sic.gov.co). This policy has been in force since the date at the top of this page, and the database lasts for as long as the purposes described here.

Argentina

You can exercise the rights of access, rectification and deletion of Law 25.326: we answer access requests within 10 calendar days, and rectification or deletion requests within 5 business days. The owner of personal data may exercise the right of access to it free of charge at intervals of no less than six months, unless a legitimate interest is shown, as established in article 14, paragraph 3 of Law No. 25.326. The Agencia de Acceso a la Información Pública, as the supervisory body of Law 25.326, is empowered to hear the complaints and claims of anyone whose rights are affected by a breach of the data-protection rules in force.

Brazil

You have the rights listed in article 18 of the LGPD, including confirmation that we process your data, access, correction, anonymization or deletion, portability, and information about whom we share it with. [email protected] is our channel for them, and you can complain to the ANPD.

United States

We do not sell personal data, we do not share it for cross-context behavioural advertising, we run no advertising and no third party collects information about your activity across other websites through our Service. For that reason the Service works the same whether or not your browser sends a "Do Not Track" or Global Privacy Control signal. Whatever state you live in, you can make the access, correction and deletion requests described above.

10If you use CubicBuilds through an organization

When you work inside an organization created by someone else (your team, your employer, a client), that organization decides what goes into its projects and who its members are, and a request about that content may need to go through the organization's owner.

Business customers who need a data-processing agreement can ask for one at [email protected]. The content of an organization that has one stays out of the showcase and the style library.

If someone invited you, we received your email address from that person in order to create the invitation. If you do not want it, ask us to delete it.

11Age

CubicBuilds is for people aged 16 or over. Those under 18 need the permission of a parent or guardian, as the Terms explain. The Service is not directed to children under 16 and we do not knowingly collect their data. If you believe a child under 16 has given us personal data, write to [email protected] and we will delete it.

12How we protect it

We protect your data with measures suited to the risk:

  • Each organization's data is isolated from the others at the database level.
  • Connections to the Service are encrypted, and the browser is only allowed to load content from our own servers.
  • Session identifiers, sign-in codes and invitation tokens are stored only as hashes, and Discord tokens are stored encrypted.
  • The code the AI writes runs in isolated environments with no network access and no access to secrets.
  • Uploaded files are held apart and checked before they are used.
  • Access by our staff is limited to those who need it, and their actions on customer organizations are recorded.

No system is completely secure. If a breach affects your data, we will tell you and the authorities as the law requires.

13Cookies

We use only the cookies needed for the Service to work and to remember your preferences. There is no advertising and no analytics. The Cookie Policy lists each one.

14Changes to this policy

We may update this policy when the Service or the law changes. The date at the top shows the last update. If a change is significant, we tell you by email or in the app before it applies.
