These Terms of Use apply to the public website available at and.guide. The site is operated by 1990Company as an editorial project focused on DNS, subdomains, HTTPS, and related developer workflows.

Operator details

  • Operator: 1990Company
  • Operator profile: About and.guide
  • Location: South Korea
  • Public website: and.guide
  • Public contact: admin@and.guide
  • Current scope: technical guides, free browser tools, and DNS records for a small number of approved project subdomains

1. Scope

These terms apply to your use of the public website, including:

  • reading guides and policy pages
  • using the browser tools, public navigation, and search
  • requesting a project subdomain
  • contacting the site operator by email

The current public site does not offer self-serve paid plans, hosted user accounts, or a guaranteed support SLA.

2. Editorial Content

The guides on and.guide are published for general informational purposes. They are written to help developers understand technical workflows, but they are not legal, financial, tax, health, or security-certification advice.

You are responsible for reviewing whether a guide fits your own environment before relying on it in production.

3. Browser Tools

The tools on and.guide are provided free of charge to help you check and plan DNS and certificate configuration. Results depend on your input and, for the DNS lookup, on answers returned by third-party resolvers (Cloudflare and Google) at the moment of the query. Treat tool output as an aid to your own verification, not as a guarantee that a configuration is correct or complete.

4. Subdomain Records

and.guide may add DNS records for a limited number of approved project subdomains. An approved subdomain is only a DNS record in the and.guide zone that points at a service you operate. and.guide does not host, operate, or monitor that service, and you remain responsible for its content, availability, security, and certificates.

The operator may change or remove a subdomain record at any time, including when the target no longer serves the approved project, when the record could be claimed by someone else, when the content breaks these terms or applicable law, or when the record puts visitors at risk. Approval of one request does not create a right to a particular name or to future requests.

5. Acceptable Use

You may not use this website to:

  • attempt to interfere with site availability
  • scrape the site in ways that violate published access restrictions
  • misrepresent the site’s content as your own work without attribution
  • send abusive, fraudulent, or unlawful communications through public contact channels

6. Intellectual Property

Unless otherwise stated, the published content, layout, and branding on and.guide are owned or controlled by the site operator. Short quotations with attribution are generally acceptable, but full copying or republication of substantial content requires permission.

Guides may link to official documentation or third-party resources. Those links are provided for convenience. The site operator is not responsible for third-party content, policies, outages, or changes.

8. No Warranty

The site is provided on an “as is” and “as available” basis. The operator does not promise that every page will be error-free, uninterrupted, or suitable for a particular technical environment.

9. Limitation of Liability

To the fullest extent permitted by applicable law, the site operator is not liable for indirect, incidental, consequential, or special damages arising from your use of the website or reliance on its content.

10. Changes

These terms may be updated when the site changes materially or when policy language needs correction. The effective date shown at the top of this page changes when that happens.

11. Contact
