Shift calculations run in a browser worker. The shift list is saved in local site storage for up to 24 hours so a result can be refreshed. You can delete it on the result page or clear site storage in your browser. Downloads remain on your device until you delete them.

No analytics or advertising tags are installed in this release. Normal web-server logs can include IP address, request time, browser details and the requested path. Result paths contain a random identifier, not shift rows.

The contact form sends your name, email and message to a private server inbox. These records are used to review the request; they are retained for up to 90 days. Do not send health records. Use the contact form to request deletion and provide the email used in the original message.
