The local workbook check
Your selected workbook is processed in your browser. This tool does not transmit the workbook or its analysis to Rowan Workshop or an AI provider. It does not save the file in browser storage. Clear removes the current selection and report. Downloaded files remain on your device until you delete them.
Website visits
This site adds no advertising pixels or third-party analytics. Hosting and network providers process ordinary request information, such as IP addresses and access logs, under their own policies. The public domain uses GitHub Pages. Ordinary web visits are not necessarily anonymous.
Project enquiries
The enquiry form prepares an email in your email app or copies text to your clipboard. It does not submit that text to a server. Email you send to daavidrowan@gmail.com is received and processed through Gmail. Send a project description first. Do not include passwords, customer datasets or confidential attachments.
Paid project materials
Secure intake, processing terms and payment arrangements are being prepared. Before a paid review, you will receive the scope, required inputs, processing arrangements and retention terms. Do not send source files or credentials before these are confirmed. Customer material will not be reused publicly without permission.
Questions or deletion requests
Email daavidrowan@gmail.com about privacy or a previous enquiry. Identify the relevant message if requesting deletion. Necessary business records may require separate retention.
