What is browser storage?

Browser storage is a mechanism that keeps the data of a website or tool inside the web browser on the device you are using. Without creating an account, you can sometimes pick up where you left off the next time you open it in the same browser.

How it differs from server or cloud storage

With server or cloud storage, your data is sent to a storage location on the internet. With browser storage, the data stays, in principle, inside your own device and browser.

That makes it easy to use without logging in or sending anything over the network. The other side of that is that the data cannot be carried over to another device automatically.

Where is it stored?

It is stored in the same browser, on the same device. For example, data saved in Chrome on a computer does not appear automatically in Edge or Firefox on that same computer. It does not move to your phone automatically either.

Situations where the data can be lost

Data in browser storage can be lost by any operation that clears data on your device. Keeping something important stored only here is not recommended.

• When you delete site data or browsing data
• When you reset or uninstall the browser
• When you use a private window (incognito mode and the like) and close it

When you want to delete it

Some works have a delete or reset button inside the work itself. If you cannot find one, you can delete that site's "site data" from your browser settings. Note that doing so may clear all of the saved data for that site at once, so make a copy of anything you need first.

Backups are recommended

For data that matters, it is safer to save it out as a file where an export feature is available. Some works can create a backup in a format such as JSON, which you can load back in later. JSON is a text file format used to record data together in one place.

For works without an export feature, we recommend making a note of what is on the screen, or copying it somewhere else, as needed.

About network communication

Even in a tool that does not send your work data anywhere, communication can still occur — for example for the access analytics used to see how pages are viewed, or to display ads and external fonts. For how each work handles data, please check its own introduction page.

For how information is handled across the site as a whole, please see the privacy policy.
