The dangerous part of a hot shift is not the metal. It is the contour nobody walked. FurnaceShift Contours gives masters, operators, and brigade leads a single ordered pass, so the next crew can trust what was finished and see what was left behind.
Run a heatA beat unlocks only when every earlier required beat is finished or skipped with a written tag. A skipped beat stays on the record. A beat that waits on another stays blocked until that one is clear.
Walkdown, heat prep, process, quality, safety, and handover stay required until the crew clears the beat ahead.
A skipped contour carries its manual tag and stays visible to everyone after you.
Split a short heat from a full shift of the same unit. The next unfinished beat is what the floor still owes.
Read two heats, or a furnace against a caster and a mill, before the shift is let go.
Expected beats come from the unit itself, never from invented readings.
A finished heat is archived with its full record, checks and tags included.
🔥 We are a small crew that cares about the hours between charge and handover. We built FurnaceShift Contours for masters, operators, and brigade leads who carry a whole heat in their heads and want it written down in order.
🎯 Our mission is simple: make sure no contour goes unwalked. Heat prep open at charge, a cast beat with no safety card, a handover closed on a gap. These are the things we want to make visible before they become incidents.
📋 The app keeps one ordered pass for every heat. A contour reaches done only when its checks are written, earlier beats are finished, and anything it waits on is clear. You compare units, split short heats from full shifts, and archive with the record intact.
⚒️ Finish the pass. Trust the handover.
Effective Date: September 2026
FurnaceShift Contours does not collect, store, or share any data. Everything, from your heat records to your manual tags, stays on your device.
None. We do not gather names, shift rosters, unit data, heat records, tags, device identifiers, or usage statistics. The app has nothing to send because it never reads anything beyond what you type in.
Since we hold no information, we do not use it, analyze it, profile it, or sell it. Your walkdowns, checks, and handover notes are used by the app only to show you your own contours.
Heat records, beat states, skip tags, and archives live only in local storage on your device. There is no cloud, no server, and no sync. We cannot see your data and neither can anyone else through us.
The app includes no third-party analytics, advertising networks, crash reporters, or trackers. Nothing in it phones home.
Because the app works entirely on your device, your records are protected by that device's own security. We recommend a screen lock and current system updates, especially on shared floor terminals.
The app is built for industrial crews, but it is COPPA-friendly by design: it collects no personal information from anyone, including children under 13.
There are no accounts to create or close. You can clear any heat inside the app, and removing the app deletes everything it ever stored on your device.
If this policy changes, we will update the date at the top of this page. Because we collect nothing, we expect the core promise to stay the same.
