Privacy
Your information,
handled with purpose.
This notice describes how Paul Arntz, operating as Useful Systems, handles information collected through this website.
Information you choose to send
The inquiry form collects your name, email address, optional business name, selected area of interest, and message. This information is used to respond to your inquiry, discuss a potential engagement, and maintain related correspondence.
Website hosting and form processing
The site is configured for hosting and form processing through Netlify. When you visit or submit a form, the hosting provider may process technical information such as your IP address, browser information, and request logs to deliver the site, protect it from abuse, and process submissions.
Analytics and advertising
This version of the site does not include advertising trackers or third-party analytics scripts. Fonts are served with the website rather than requested from an external font service. Inquiry details are not sold or used to add you to a marketing mailing list.
If you arrive from our Google Search promotion, the site remembers that campaign's label in your browser tab for the session and includes it with an inquiry you submit. This helps us understand whether the promotion produces useful inquiries. We do not store advertising click IDs or send your inquiry details to Google through the site.
Access and retention
Information may be handled by the service providers needed to host the website and manage correspondence. Inquiry details are kept for responding to the request and managing related business records, then reviewed for deletion when no longer needed.
Keep sensitive information out of the form
Please do not send passwords, financial account information, private customer records, or other sensitive material through the inquiry form. If a project requires confidential information, an appropriate way to share it can be agreed separately.
Questions or requests
To ask about your information or request correction or deletion, use the contact form and mention “privacy request.” Please provide only the information needed to identify your earlier inquiry.
Changes to this notice
This notice will be updated if the website’s data practices change. Last updated September 13, 2026.
