Do you store the values I enter?
No. The Regex Tester is stateless: refresh the page and every input is gone. Nothing is written to a database.

What if I get an unexpected result?
Re-check your inputs — units, decimal points and currency values are the most common cause. If it still looks wrong, contact us and we'll investigate.
Will this help my pages rank on Google?
It helps you ship technically clean pages — correct metadata, structured data, clean URLs and valid markup — which is the foundation Google and AI Overviews rely on.
Is the generated code safe to paste into production?
Yes. Output is plain, standards-compliant HTML/JSON/text with no tracking or external calls. Review it once before deploying, as you would with any generated snippet.
Does it send my code or URLs to a server?
No. Every transformation happens client-side in JavaScript, so proprietary code, tokens and internal URLs never leave your machine.
Does the output work with AI search engines?
Yes. Clean structured data and descriptive metadata are exactly what ChatGPT Search, Perplexity and Google AI Overviews parse when citing sources.
