Terms of Service

Last Updated: September 11, 2026

Welcome to dbNexus. These Terms of Service ("Terms") govern your access to and use of the dbNexus website, applications, APIs, workspaces, and related services (collectively, the "Platform" or "Service").

By creating an account, accessing, or using dbNexus, you acknowledge that you have read, understood, and agree to these Terms.

Important: If you do not agree with these Terms, please do not access or use dbNexus.

dbNexus is a web-based database schema design and collaboration platform built around DBML (Database Markup Language).

The Platform enables developers, database administrators, software architects, and engineering teams to design, visualize, document, and collaborate on database schemas.

dbNexus provides tools for transforming declarative database definitions into interactive visual representations and production-ready SQL scripts.

dbNexus may provide the following capabilities:

1. DBML Schema Design — Create and edit database schemas using DBML.
2. Visual ER Diagrams — Visualize tables, columns, relationships, indexes, and constraints.
3. SQL Import — Import supported SQL DDL definitions and convert them into database schemas.
4. SQL Generation — Generate SQL DDL for supported database engines.
5. Table Groups — Organize database tables into logical domains or functional groups.
6. Schema Documentation — Document database structures, columns, relationships, and business definitions.
7. Workspaces — Organize schemas and projects within personal or collaborative workspaces.
8. Collaboration — Share and work on database designs with authorized team members.
9. Export — Export supported schemas and diagrams into available formats.

Features may vary depending on your account type, subscription, or plan.

Certain dbNexus features require an account.

When creating an account, you agree to provide accurate and current information.

You are responsible for:

• Maintaining the confidentiality of your login credentials.
• Keeping your account information accurate.
• Protecting access to your account.
• All activities performed through your account.
• Notifying dbNexus if you believe your account has been compromised.

You must not use another person's account without authorization.

Warning: Never store database passwords, API keys, access tokens, private keys, or other credentials inside dbNexus schema definitions.

dbNexus may allow users to create personal or collaborative workspaces.

Workspace owners and administrators are responsible for managing workspace access.

This may include:

• Inviting users.
• Removing users.
• Assigning permissions.
• Managing workspace members.
• Controlling access to schemas.
• Managing shared database documentation.

Users who are granted access to a workspace may be able to view, modify, or export workspace content depending on their assigned permissions.

Note: Sharing a workspace or schema with another user may give that user access to the information contained within the shared resource. Always verify permissions before sharing confidential database designs.

For purposes of these Terms, "Customer Data" means information submitted, created, uploaded, or stored by you through dbNexus.

Customer Data may include:

• DBML definitions.
• SQL schema definitions.
• Table structures.
• Column definitions.
• Relationships.
• Index definitions.
• Constraints.
• Table groups.
• Diagram configurations.
• Documentation.
• Schema descriptions.
• Workspace content.

You retain ownership of your Customer Data.

dbNexus does not claim ownership of your database schemas, diagrams, or documentation.

You grant dbNexus a limited, non-exclusive right to host, store, process, reproduce, transmit, and display Customer Data only as reasonably necessary to provide, maintain, secure, and improve the Service.

dbNexus is primarily designed for database schema design and documentation.

The Platform is not intended to act as a database hosting service.

For example, a schema may contain:

Table Users {
    id int [pk]
    username varchar
    email varchar
}

Table Orders {
    id int [pk]
    user_id int
}

This represents database structure, rather than the actual records stored inside the database.

dbNexus users are responsible for determining what information they submit to the Platform.

Warning: Do not intentionally upload production database records, database credentials, passwords, authentication tokens, encryption keys, or other secrets unless a specific dbNexus feature explicitly requires and supports such information.

You agree to use dbNexus only for lawful and authorized purposes.

You must not:

1. Attempt to gain unauthorized access to another user's account or workspace.
2. Circumvent authentication or security controls.
3. Upload malicious software or harmful code.
4. Interfere with the operation of the Platform.
5. Abuse APIs, automated systems, or infrastructure.
6. Perform unauthorized security testing against the Platform.
7. Attempt to reverse engineer security mechanisms.
8. Scrape or systematically collect Platform data without authorization.
9. Impersonate another person or organization.
10. Use dbNexus to violate applicable laws or regulations.
11. Upload content that infringes third-party intellectual property rights.
12. Use the Platform to distribute malware, phishing content, or other harmful material.

dbNexus may restrict, suspend, or terminate accounts that violate these requirements.

dbNexus and its underlying technology are protected by applicable intellectual property laws.

This includes, where applicable:

• Software.
• Source code.
• User interface.
• Platform architecture.
• Visual designs.
• Branding.
• Logos.
• Documentation.
• APIs.
• Proprietary functionality.

Except for rights expressly granted under these Terms, no ownership rights are transferred to you.

Your use of dbNexus does not grant you ownership of the dbNexus Platform or its underlying technology.

You are responsible for ensuring that you have the necessary rights to submit Customer Data to dbNexus.

You represent that your Customer Data:

• Does not unlawfully infringe third-party rights.
• Does not violate applicable laws.
• Does not contain unauthorized confidential information.
• Can legally be processed by dbNexus for the purposes described in these Terms.

dbNexus does not claim ownership of your original database schemas or documentation.

dbNexus may provide functionality for sharing schemas, diagrams, documentation, or workspaces.

If you choose to make content publicly accessible, you understand that other users or Internet users may be able to access that content depending on the sharing configuration.

You are responsible for determining whether content should be:

• Private.
• Shared with selected users.
• Shared with a workspace.
• Publicly accessible.

Warning: Do not publish proprietary database architecture, confidential business information, credentials, or sensitive information through public sharing features.

dbNexus may rely on third-party services to provide certain functionality.

These services may include:

• Cloud infrastructure.
• Authentication providers.
• Database services.
• File storage.
• Email providers.
• Payment processors.
• Analytics services.
• Monitoring services.

Your use of certain third-party services may also be subject to their respective terms and privacy policies.

dbNexus is not responsible for the independent operation of third-party services.

dbNexus is designed to provide a reliable and continuously available service.

However, we do not guarantee that the Platform will always be:

• Available.
• Error-free.
• Uninterrupted.
• Completely secure.
• Free from defects.

Service interruptions may occur because of:

• Scheduled maintenance.
• Infrastructure failures.
• Software updates.
• Network failures.
• Security incidents.
• Third-party service failures.
• Events outside our reasonable control.

Certain dbNexus functionality may use a local-first architecture, where schema drafts or temporary application state may be stored within your browser or local device before synchronization with a connected workspace.

Depending on the feature being used, data may subsequently be synchronized with dbNexus cloud services.

Users are responsible for maintaining appropriate backups of important schemas and documentation.

Note: Local browser storage should not be considered a guaranteed backup or permanent storage mechanism.

Certain dbNexus features may require a paid subscription.

Subscription plans may define:

Specific limits and features depend on the plan selected by the customer.

dbNexus may introduce new plans or modify existing plans.

Paid subscriptions are billed according to the billing period selected during purchase.

Depending on the applicable subscription:

• Subscriptions may automatically renew.
• Applicable taxes may be added.
• Payment information must remain valid.
• Subscription fees may be non-refundable except where required by law or explicitly stated otherwise.

You authorize dbNexus or its payment provider to charge applicable subscription fees.

You may cancel a subscription using the cancellation mechanisms provided by dbNexus.

Cancellation generally prevents future renewal but does not automatically provide a refund for a previously paid subscription period unless otherwise specified.

After cancellation or expiration:

• Paid features may become unavailable.
• Workspace limits may change.
• Export functionality may be restricted.
• Additional storage may no longer be available.

dbNexus may provide tools for exporting database schemas, diagrams, documentation, or other supported content.

Tip: We recommend maintaining independent backups of important database schemas and documentation.

Users may request deletion of their account or applicable Customer Data.

When data is deleted, it may become permanently unrecoverable.

Certain information may be retained where reasonably necessary for:

• Legal compliance.
• Accounting requirements.
• Fraud prevention.
• Security investigations.
• Dispute resolution.
• Enforcement of contractual rights.
• Backup and disaster-recovery processes.

Backup copies may remain temporarily until they are overwritten or securely deleted according to applicable retention procedures.

Security measures may include:

• Authentication controls.
• Authorization mechanisms.
• Access controls.
• Encryption where appropriate.
• Infrastructure security.
