+# About the web app
+
+The web app provides access to Joplin from a web browser.
+
+Like the desktop and mobile apps, the web app is local-first:
+- Notes and attachments are stored locally on your computer. Changes are saved even if offline.
+- [Synchronisation](https://joplinapp.org/help/apps/sync/) needs to be enabled/configured to sync data to the cloud.
+- Until synchronisation is configured, each different browser/profile will have a different note collection.
