Storage API

Checking compatibility...

The Storage API provides a way to find out how much storage space is available for a site, how much is being used, and to request persistent storage that won't be automatically cleared.

Storage Estimation

Find out how much storage space your app is using and how much is available. This helps you make smart decisions about caching content, storing user data, and managing offline capabilities without running into storage limits.

Storage Persistence

Ask the browser to protect your app's data from automatic deletion. When storage is persistent, browsers won't clear your app's data during routine cleanups, making your app more reliable for users who depend on offline access or saved preferences.
