What local storage means

Local storage is a small browser feature that lets a website save simple data on your device. Tool sites may use it for bookmarks, theme preference, recent settings, high scores, or drafts. It is different from saving information in a server database.

When it is helpful

  • Remembering tools you bookmarked.
  • Keeping a game high score.
  • Saving display preferences.
  • Restoring a small draft after refresh.

Common mistakes

Do not treat browser storage as secure long-term storage. Other people using the same browser profile may be able to see saved data. Clear site data if you use a shared machine.

FAQ

Does local storage follow me to another device?

Usually no. It stays in the browser profile where it was saved.

Should sensitive data be stored locally?

Avoid storing secrets, private keys, financial records, or personal data unless you understand the risk.

Be careful with sensitive documents. Avoid uploading confidential, legal, financial, or personal files to any online tool unless you understand how the tool handles processing and storage.
