Last updated: August 28, 2026

Information you provide

CostFiled may receive your email address and the city or project you enter when you submit a notification or request form. We use that information to respond to you, evaluate requests, and send updates you explicitly ask for. We do not sell contact information.

Site and measurement data

The site may process basic technical information such as browser type, device type, referring page, and pages visited through hosting logs and analytics services. We use this information to keep the site reliable and understand which guides are useful. We do not ask for sensitive personal information.

Advertising and cookies

CostFiled may use Google AdSense or other advertising services. Those services may use cookies or similar technologies to measure advertising performance and, where permitted, personalize ads. Their handling of data is governed by their own policies and controls. You can manage cookies in your browser and review Google’s ad settings.

Your choices and contact

You can ask us to correct or delete information you submitted by emailing support@aishortsystem.com. We retain contact requests only as long as reasonably necessary for the purpose for which they were submitted or to meet legal obligations.
