Your data

Everything you create in KimtOS is stored in your browser, on your machine. Notes, tasks, PDFs and their annotations, clipboard history, whiteboards, recordings, AI conversations — none of it is uploaded, and we have no copy.

That is the point of the product. It also means the backups are your job, and this page is how you do them.

Back up: Settings ▸ Data

Open Settings (click your avatar, top right) and choose Data.

Export my data downloads a single file — kimtos-backup-2026-07-12.json — containing everything: every record, every file, every setting. Keep it somewhere safe.

Import a backup takes that file and restores it, then reloads the page.

Import merges, it does not replace

Importing adds and overwrites what is in the file. It does not wipe what is already there — anything not mentioned in the backup is left alone.

So importing an old backup on top of a workspace you have been using does not roll you back to that snapshot. It merges the two. If you want a clean restore, clear the data first (see AnubisDB below), then import.

Two more things the backup does not contain:

• Your sign-in. You will need to sign in again after restoring on a new machine.
• The AI models. They are large, and they re-download by themselves when needed.

Moving to a new computer

1. On the old machine: Settings ▸ Data ▸ Export my data.
2. Install KimtOS on the new machine and sign in (this unlocks Pro, but the workspace is empty).
3. Settings ▸ Data ▸ Import a backup and choose the file.

This is the only way to move your work. Signing in does not bring it with you.

AnubisDB: see everything KimtOS has stored

AnubisDB is a free app, installed by default. It is a window onto the database itself: every app, what it has stored, and how much space it takes.

From the toolbar:

Button	What it does
Refresh	Re-reads the database
Import	Restores a backup file
Export all	The same full backup as Settings ▸ Data
Clear all	Erases everything, with an Undo in the snackbar

Click any app to see just its data, and to Export or Clear that one app on its own. Deleting an app's data asks you to confirm first, and offers an Undo afterwards.

Undo is only good for a few seconds

The Undo on a clear lives in memory, in that snackbar. Once it disappears, the data is gone for good. Export before you clear anything you might want back.

AnubisDB also has a Model storage section listing the downloaded AI models, with a Free button for each. Freeing one reclaims the space; the model downloads again next time you use that app.

Removing an app keeps its data

Uninstalling an app from the App Store does not delete what you made with it. The dialog says so, and offers a checkbox — "Also erase my notes & collections — this can't be undone" — which is unticked by default.

Leave it unticked and your notes wait for you, exactly as they were, if you ever install Notes again. Tick it only if you really mean it.

If the app had downloaded an AI model, that model is freed to reclaim the space (unless another installed app is using the same one).

The one thing that really does delete everything

Removing KimtOS from Chrome deletes all of it

If you uninstall the KimtOS extension itself, Chrome deletes its storage — every note, task, PDF, board and recording, gone. That is Chrome's behaviour and we cannot prevent it.

Export first. Always.

The same applies if you clear your browsing data and include site data for extensions.

Where it actually lives

For the curious: an IndexedDB database called kimtos inside your browser profile, plus Chrome's extension storage for your settings. The AI models sit in the browser's cache storage, separately, which is why they are not in your backup and can be freed without touching your work.
