Persistent Storage & SQLite

File storage

Your app can save files. Once a write returns, the data is durable — there is no background sync and nothing depends on a local disk that resets on redeploy.

• App data files — files your app names and updates in place (saved state, settings, small caches). Writes are whole-file and take effect immediately; these files are private to your app.
• Media — images, PDFs, and other uploaded or generated media are uploaded to a dedicated store, referenced by an ID, and served over a URL.

For data you read and write on every request, use the managed database instead.
