We use no advertising or tracking cookies, and no third-party analytics. Nothing here follows you to other websites, and no outside company receives a record of your visit.
| Cookie | Set by | Purpose |
|---|---|---|
| Session cookie | Clerk (our authentication provider) | Keeps you signed in between page loads. Strictly necessary — without it you would have to sign in on every request. |
That is the complete list. Because we set no cookies beyond what is strictly necessary to sign you in, we do not show a cookie consent banner.
Most of what the application keeps locally is not a cookie at all — it is stored in your browser so the software keeps working without a network connection. This is the mechanism that lets you carry on designing during an internet outage.
| What | Where | Why |
|---|---|---|
| Your current working session — designs, machines, labs, tracking runs, calibration history, runsheet settings | IndexedDB | So a reload, or losing your connection, does not lose your work |
| Your designs and settings | IndexedDB | A local copy alongside the copy in your account, and the only copy until you are back online |
| Your plan and its limits | IndexedDB | So an outage does not incorrectly restrict features you pay for |
| Custom material definitions | Local storage | So materials you have characterised are available immediately on load |
| Dark mode preference | Local storage | So the interface does not flash the wrong theme on load |
| Application files | Cache storage (service worker) | So the application opens with no internet connection |
None of the above is transmitted anywhere except through the normal syncing of your account described in our Privacy Policy.
If a different account signs in on the same browser, this local copy is erased before the new user can see anything. That matters on a shared workstation in a coating shop, which is why it works that way.
You can clear everything at any time through your browser’s settings for site data — usually under “Privacy” or “Cookies and site data”. Doing so signs you out, removes the offline cache, and deletes any change made on this device that had not yet reached your account.
