Browser-local engineering document processing
The engineering report generator, technical specification generator, project summary formatter and research abstract utility are designed so that the notes, formulas, numerical values and generated document content entered in the main workspace are processed in the visitor's browser. The workspace does not intentionally transmit that engineering content to profeng.net application servers, and the utility does not provide a server-side account, project database or document archive for those inputs.
Advertising, analytics and third-party technologies
profeng.net uses Google AdSense to support free access and Google Analytics to understand aggregate site usage. Google and other advertising technology providers may place or read cookies on a visitor's browser, use web beacons, process IP addresses or use other identifiers as part of ad serving, measurement, fraud prevention, frequency control and advertising personalization where permitted. Google explains how it uses data from partner sites at Google's partner-site data information page.
Google AdSense documentation describes advertising cookies associated with Google domains and doubleclick.net. Older privacy materials sometimes use the term DoubleClick or DART cookie. Current operation is governed by Google's present advertising-cookie and consent systems rather than by this historical label alone.
Consent choices
Where applicable, visitors may be presented with a consent-management message for advertising and related data processing. Visitors can revisit available choices using the Privacy & Cookie Settings control in the site footer. Google advertising personalization preferences can also be reviewed through Google Ads Settings.
Anonymous support messages
The support form deliberately does not ask for a name, telephone number, personal email address or postal address. A submitted category and message are transmitted to The profeng.net Automation Systems Queue through network and email-delivery infrastructure. Although the form does not request identity fields, infrastructure providers may process technical metadata such as IP address, user agent, timestamps or anti-abuse signals as part of transmission and security.
Data minimization and sensitive information
Do not place confidential project information, personal data, credentials, trade secrets or regulated information into the anonymous feedback form. Engineering workspace content remains local to the browser session unless the visitor independently copies, downloads, prints or otherwise shares it.
