Culpur Defense Inc. (“Culpur Defense,” “we,” “us,” or “our”) operates the culpur.net website, the AnvilHub marketplace (anvilhub.culpur.net), and the Anvil command-line application. This Privacy Policy explains what information we collect, how we use it, and the choices you have. We designed our products to minimize the data we collect — in particular, the Anvil application is built to keep your credentials and source code on your own machine.
Who we are
The data controller is Culpur Defense Inc. For any privacy question or request, contact us at [email protected].
Information we collect
Account information. When you create an AnvilHub account or sign in, we collect the information you provide or that your identity provider shares with us — typically your name, email address, and an account identifier. Authentication is handled through our single sign-on provider; we do not store your password in plaintext.
Usage and diagnostic data. When you use culpur.net or AnvilHub, our servers and content-delivery network (Cloudflare) automatically record standard request data such as your IP address, browser type, referring page, and timestamps, for security, abuse-prevention, and reliability purposes.
Marketplace activity. If you publish, install, or interact with skills, plugins, agents, or themes on AnvilHub, we record the activity necessary to provide those features (for example, which package was installed, and install success or failure).
The Anvil application. Anvil runs locally on your own computer. Your API keys, OAuth tokens, vault contents, source code, and conversation history are stored on your machine and are not transmitted to Culpur Defense. Anvil sends your prompts and code only to the AI provider you configure (for example Anthropic, OpenAI, Google, or a local model), using your credentials. Anvil may contact culpur.net / anvilhub.culpur.net for update checks, version information, and marketplace operations; these requests carry only what is needed for those functions.
How we use your information
- To provide, maintain, and improve culpur.net, AnvilHub, and Anvil;
- To authenticate you and secure your account;
- To operate the marketplace (publishing, installs, listings);
- To detect, prevent, and respond to fraud, abuse, and security incidents;
- To communicate with you about your account, security, or service changes; and
- To comply with legal obligations.
We do not sell your personal information.
Cookies
culpur.net and AnvilHub use cookies and similar technologies that are necessary for the site to function — for example, to keep you signed in and to remember session and display preferences. We do not use cookies to build advertising profiles. You can control cookies through your browser settings; disabling necessary cookies may prevent parts of the site from working.
Third parties we share data with
We share information only with service providers that help us run our services, and only as needed:
- Cloudflare — content delivery, DNS, and security/DDoS protection.
- Our authentication provider — single sign-on and account security.
- AI providers you choose — when you use Anvil, your prompts and code are sent directly to the provider you configure, under that provider’s own privacy policy and your own account. Culpur Defense is not a party to that exchange.
We may also disclose information when required by law, to enforce our agreements, or to protect the rights, safety, and security of our users and our services.
Data retention
We retain account and marketplace data for as long as your account is active or as needed to provide our services, and afterward only as required for legal, security, or legitimate-business purposes. Server and security logs are retained for a limited period and then deleted or anonymized.
Your rights
Depending on where you live, you may have the right to access, correct, export, or delete the personal information we hold about you, and to object to or restrict certain processing. To exercise any of these rights, email [email protected]. We will respond within the time required by applicable law. We will not discriminate against you for exercising your rights.
Security
We use technical and organizational measures to protect your information, including encryption in transit, access controls, and the design choice of keeping Anvil credentials and code on your own device. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.
Children’s privacy
Our services are not directed to children under 16, and we do not knowingly collect personal information from them. If you believe a child has provided us personal information, contact us and we will delete it.
Changes to this policy
We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date above, and significant changes will be communicated through the site or by email where appropriate.
