Terms of Service

Last updated: October 14, 2026

1. Overview

RegexCalc (regexcalc.net) provides free, client-side developer utilities and documentation. By using this website you agree to these Terms of Service. If you do not agree, do not use the site.

2. The Tool Runs in Your Browser

Text, code, queries, and calculations you enter are processed entirely in your browser. We do not create accounts, and we do not collect, transmit, or store your input. You are responsible for not pasting secrets (tokens, passwords, private keys) into any web tool, including ours.

3. Acceptable Use

• Use the tools and guides for lawful purposes, primarily software development.
• Do not attack, overload, or scrape the site in ways that degrade service for others.
• Do not republish the guides wholesale; quoting excerpts with a link back is welcome.

4. No Warranty — Review Generated Output

Everything on this site — formatted code, converted commands, calculated values, and guide text — is provided "as is", without warranty of any kind, to the extent permitted by law. Generated commands and code snippets can be subtly wrong for your particular environment or version. Always review what you paste into a shell, a database, or a deployment before running it. You are responsible for what you do with output from this tool.

5. Limitation of Liability

To the maximum extent permitted by law, the operator of this website is not liable for any damages — including lost data, lost profits, or downtime — arising from use of, or inability to use, this site or its output.

6. Advertising and Privacy

This site may display third-party advertising (Google AdSense). Advertising and cookie practices are described in our Privacy Policy, which forms part of these terms.

7. Third-Party Links and Trademarks

Guides link to external documentation and sister properties; we are not responsible for their content. Product names and logos mentioned on this site belong to their respective owners and are used for identification only.

8. Changes to These Terms

We may update these Terms of Service. The "last updated" date at the top of this page reflects the current version; material changes will be reflected in that date.
