By accessing or using Domainstack ("the Service"), you agree to be bound by these Terms of Service. If you do not agree to these terms, please do not use the Service.

Description of Service

Domainstack is a domain intelligence platform that provides information about domain registrations, DNS records, SSL certificates, hosting details, and SEO metadata. The Service allows users to:

  • Look up publicly available domain information
  • Track domains and receive expiration notifications
  • Monitor SSL certificate validity
  • View hosting and DNS provider information

Account Registration

To access certain features, you must create an account using one of our supported external providers. You agree to:

  • Provide accurate and complete information
  • Maintain the security of your account
  • Accept responsibility for all activities under your account
  • Notify us immediately of any unauthorized access

Acceptable Use

You agree not to:

  • Use the Service for any illegal purpose
  • Attempt to gain unauthorized access to any part of the Service
  • Use automated tools to excessively query the Service (scraping)
  • Interfere with or disrupt the Service or its infrastructure
  • Impersonate others or misrepresent your affiliation
  • Use the Service to harass, abuse, or harm others

Domain Verification

When tracking domains, you may be required to verify ownership through DNS records, HTML files, or meta tags. You represent that:

  • You have the right to verify ownership of domains you add
  • You will not attempt to verify domains you do not own or control
  • Verification is for notification purposes and does not transfer any rights

AI Assistant

We provide an optional AI-powered chat assistant to help you look up domain information using natural language. By using this feature, you acknowledge and agree to the following:

Intended Use

  • The AI assistant is designed solely for domain-related queries
  • It can look up WHOIS/RDAP records, DNS records, SSL certificates, hosting information, and SEO metadata
  • The assistant will decline requests unrelated to domain information

Limitations and Disclaimers

  • AI responses may contain errors. The assistant uses large language models that can make mistakes, misinterpret queries, or provide incomplete information
  • Not a substitute for professional advice. Do not rely on the AI assistant for legal, financial, or security decisions regarding domains
  • Third-party data. Information retrieved by the assistant comes from public sources and may not be current or accurate
  • No guarantee of availability. The AI feature may be modified, suspended, or discontinued at any time

Acceptable Use

You agree not to:

  • Attempt to manipulate, jailbreak, or bypass the assistant's guidelines
  • Use the assistant to generate harmful, abusive, or illegal content
  • Excessively query the assistant to circumvent rate limits
  • Use automated tools to interact with the AI assistant

Rate Limits

To ensure fair access for all users, the AI assistant is subject to rate limits. Free users have lower limits than authenticated users. Exceeding these limits will temporarily restrict access.

Data Accuracy

The Service provides information from various public sources including WHOIS/RDAP databases, DNS servers, and website content. While we strive for accuracy:

  • We do not guarantee the accuracy of third-party data
  • Information may be cached and not reflect real-time changes
  • You should independently verify critical information before making decisions

Service Tiers and Limits

The Service offers a free tier and a paid Pro tier with different limits on tracked domains and features:

  • Pro tier: Increased domain tracking limits and priority support

We reserve the right to:

  • Modify service tiers and their features with reasonable notice
  • Adjust usage limits with reasonable notice
  • Change pricing with 30 days notice to existing subscribers

Intellectual Property

The Service and its original content, features, and functionality are owned by Domainstack and are protected by copyright, trademark, and other intellectual property laws. Domain data displayed is sourced from public databases and remains the property of respective registries.

Disclaimer of Warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE.

Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, DOMAINSTACK SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING FROM YOUR USE OF THE SERVICE, INCLUDING BUT NOT LIMITED TO LOSS OF DATA, REVENUE, OR BUSINESS OPPORTUNITIES.

Termination

We may terminate or suspend your account at any time for violation of these terms or for any other reason at our discretion. Upon termination, your right to use the Service will cease immediately.

Changes to Terms

We reserve the right to modify these terms at any time. We will notify users of significant changes via email or through the Service. Continued use after changes constitutes acceptance of the new terms.
