Backup & Restore

Storage in this browser

Browsers cap what one site may keep. When this fills up, tools stop being able to save — often silently — so it is worth knowing where you stand.

What’s saved right now

Scanned from this browser’s storage — every roster, saved section, and settings file any tool on this site has kept for you. Uncheck a row to leave it out of the next download.

Restore from a backup

Pick a backup file downloaded from this page. Nothing is written until you have seen what it contains and pressed Restore.

How should it be applied?

Replace — anything in the file wins. What is here now under the same name is overwritten. Add only what is missing — keeps everything on this computer as it is and brings in only rosters, sections and settings that are not here yet. The safe option when merging two machines. Combine, file wins on a clash — keeps what is only here, adds what is only in the file, and takes the file’s copy where both have the same named record.

Send directly to another device

Skip the file. Pair this browser with another device over Wi-Fi — a QR code shown here and scanned there, the same way Classroom Timer’s mirror works — and send the same backup straight across the connection. Nothing is written to disk on either end. Works only when both devices can reach each other directly (the same classroom Wi-Fi or LAN); it cannot cross the open internet.

Start a new school year

Four steps, in order: close the site’s other tabs, save an archive of everything in this browser, check the saved file, then review and clear the student data: names, scores and photos go, the setup they sit in stays. The clear stays locked until the file on your disk has been read back and found complete, so a blocked download or a full disk cannot cost you the year.

Close this site’s other tabs. A tool left open still holds this year’s names and saves them again after the clear. Close every other tab and window of this site, then check again.
Save the year archive. Every saved item and every image this site keeps, in one file. It is never locked: a passphrase forgotten over the summer would lose the year.

Check the saved file. The page reads the file back from your disk and checks every item, database and picture against what it saved.
or pick the file you saved:
Review, then clear the student data. The table is exactly what the clear will do. Names, scores, logs, photos and class lists go; the setup they sit in stays: a seating chart’s desks, hall-pass destinations, behaviour tags, a lab contract’s wording, every class name. Text you typed that holds this year’s names is listed under Your choice, set to Clear. The page looks for other open tabs again before it clears.
