FAQ
Frequently asked questions
Is the result authoritative for production?
No. HTML Escape / Unescape is designed to accelerate engineering review. Production decisions should also be checked against the relevant standards, vendor documentation, policies, and actual environment.
Is my input sent to the Technologist Tools application server?
The core calculation and transformation logic runs in your browser and the site does not provide an application API that receives the tool input. Third-party browser extensions and externally loaded resources are outside that guarantee.
