Your Data

Everything lans.cloud saves lives in this browser — not on our servers. Export it, move it to another device, or delete it. Your call.

Export your data
Nothing saved yet — use any tool and its settings will appear here.
Import from a file
Restore a previously downloaded file. Only the settings in the file are overwritten — everything else stays as it is.
Delete everything
Removes every setting this browser has stored for lans.cloud. This cannot be undone — export a copy first if you might want it back.

Why this page exists

lans.cloud has no accounts and no cloud storage — by design. When you save a spinning wheel, a class list, a scoreboard roster, or a classroom screen board, it is written to your browser's local storage and never leaves your device. That is the privacy model: there is nothing to breach on our side, nothing to subpoena, and nothing to forget to delete when you stop using the site. This page is the proof — every byte the tools have stored is listed, downloadable, and deletable right here, with no login and no support ticket.

Moving to another device

The one honest downside of browser-only storage is that it stays in that browser. The classic teacher case: you build tomorrow's classroom screen board at home, and the smartboard PC at school knows nothing about it. The fix takes a minute — export here at home, and the file downloads instantly since it is built on your device, not fetched from a server. Then import it on the school machine. The same trick works for moving between browsers on one computer, before wiping a machine, or when your school refreshes its hardware over the summer.

What the file contains — and what it can't

The export is one plain JSON file containing your saved tool settings and your theme choice, exactly as the tools stored them. There is no account ID, no email address, no analytics or tracking identifiers in it — those never existed in the first place, so they cannot be in the file. You can open it in any text editor and read everything.

Imports are checked twice. This page verifies the file is a genuine lans.cloud export and ignores anything that does not belong. Then, independently, every tool sanitizes its own data each time it loads — unknown fields are dropped and missing ones get sensible defaults. So an old export from months ago, or a file you hand-edited, imports safely: the worst case is that a tool falls back to its defaults.

Frequently Asked Questions

Does lans.cloud store my class lists on a server?

No. Class lists, saved wheels, scoreboards, and settings are stored only in your own browser (localStorage). Nothing you type into a tool is sent to or stored on our servers, which is why this page can export and delete everything locally, without an account or a support request.

How do I move my saved wheels to another computer?

On the computer that has your data, open this page and click "Download my data" — you get one JSON file. Move that file to the other computer (email it to yourself, USB stick, any way you like), open lans.cloud/my-data there, and import it. Your wheels, class lists, and boards appear the next time you open each tool.

What happens if I import an old or edited file?

Nothing breaks. The import first checks the file is a real lans.cloud export and skips anything malformed, and then every tool re-checks its own data when it next loads, filling in defaults for missing or outdated fields. Importing only overwrites the settings present in the file; everything else in your browser is left untouched.

What is in the exported file?

Only what the tools saved: your settings, lists, boards, and your light/dark theme choice, as plain human-readable JSON. There is no account information, no tracking IDs, and no hidden identifiers — you can open the file in any text editor and read every line.
