Acceptable Use Policy

Last updated: October 22, 2026

This Acceptable Use Policy ("AUP") applies to your use of the Vaulken cloud platform ("Service"). By using the Service you agree to it. A breach may lead to suspension or termination of your account.

1. Permitted Use

The Service gives AI assistants access to text-based files in a bucket you own, through the MCP protocol and the dashboard. Typical uses:

  • Personal or team knowledge bases
  • Documentation and note-taking systems, including Obsidian vaults
  • AI-assisted file management through MCP clients
  • Structured data in JSON, YAML or CSV

2. Prohibited Content

You may not use the Service with content that:

  • Breaks an applicable law or regulation
  • Infringes third-party intellectual property rights
  • Contains malware or other malicious code
  • Contains child sexual abuse material or any content exploiting minors
  • Promotes terrorism, violence, or hatred against individuals or groups
  • Contains third-party personal data without a lawful basis
  • Is defamatory, harassing, or threatening

3. Prohibited Activities

You may not:

  • Try to access other users' data or accounts
  • Reverse-engineer the hosted Service beyond what its open-source license allows
  • Run denial-of-service attacks or otherwise overload the infrastructure
  • Circumvent access controls, rate limits, or permission restrictions
  • Share account credentials or MCP URLs with people who should not have that access
  • Use the Service's temporary file URLs to serve media to the public
  • Resell or redistribute access to the Service without authorization
  • Automate account creation or drive the dashboard with bots
  • Process regulated data (health records, financial data) through the Service without appropriate safeguards and a separate agreement

4. Indexing Limits

Your files live in your own bucket, so Vaulken does not limit how much you store. The indexer handles text files, PDFs and images; other binary files (video, archives) are listed but not indexed. Plan limits apply to the number of Vaults, the monthly number of pages and images processed by AI extraction, and the monthly number of semantic search queries.

5. Rate Limits

API and MCP endpoints are rate limited so that one user cannot degrade the Service for others. Automated clients should back off when they receive a rate-limit response. Deliberately working around rate limits is prohibited.

6. Security Responsibilities

You are responsible for:

  • Keeping your account credentials and MCP URLs secure
  • Giving each client the right URL (read-write or read-only) for the access it needs
  • Keeping track of the clients connected to your Vaults
  • Regenerating MCP URLs promptly if they leak
  • The security of your bucket and its credentials, including versioning and lifecycle rules

7. Reporting Violations

Report violations of this AUP to abuse@vaulken.dev.

8. Enforcement

We may investigate and act on violations by:

  • Warning the account holder
  • Suspending access temporarily
  • Disconnecting a Vault whose content breaches section 2
  • Terminating the account
  • Reporting illegal activity to law enforcement

We make reasonable efforts to notify you before acting, except when immediate action is needed to protect the Service or to comply with the law.
