Privacy / local data
Your data stays with you.
This tool processes inputs in your browser. It has no upload API, account service, advertising SDK, or payment integration. Optional Cloudflare Web Analytics is enabled only after explicit consent and is suppressed by Global Privacy Control or Do Not Track.
Analytics choices
If you allow analytics, Cloudflare receives a pseudonymous page and performance signal for this preview host. This application does not send input values, result values, CSV contents, saved snapshots, exports, or personal form data. URLs with query strings or fragments and referrers containing them are excluded. Use the Analytics privacy choices control in the footer to withdraw consent; the loader removes its beacon and stores the denied choice.
Saved inputs
Save locally writes one input snapshot to this site's browser storage only when you press the button. Restore saved reads that snapshot. Clearing this site's storage in your browser removes it. A reset does not erase saved data. Photos and other attached files are not included in saved snapshots.
Downloads and printing
JSON and CSV downloads can contain private assumptions, costs, or job information. Keep them private unless you choose to share. Print output uses your browser and printer settings. Attachments are held only for the open page session.
Hosting
Cloudflare serves this site and may process ordinary request information such as IP addresses and user agents for delivery and security. Input values and attachments are not sent in those requests by this application.
External sources
Source links open official or reference websites under their own policies. No affiliate tracking parameters are added by this tool.
