On-device site data in Google Chrome refers to information that websites store locally on your phone to improve performance, personalization, and usability.
You can allow websites to temporarily save data on your device to make your experience on their website better. This is called “on-device site data,” and when turned on, it helps websites do things like keep your shopping cart active when you leave.
You can choose how a website saves data on your device:
- Allow sites to save data on your device: Sites are more likely to work as you expect.
- Delete data sites have saved to your device when you close all windows: Sites will probably work as you expect but are less likely to remember you from one visit to the next.
- Don’t allow sites to save data on your device (not recommended): Sites may not work as you expect. Choose this option if you don't want to leave information on your device about sites that you visit.
This data includes cookies, cached images and files, and other storage like local site data. Websites use it to keep you signed in, remember your preferences, and load pages faster when you revisit them.
Because the data is stored on your device, Chrome can quickly access it without needing to reload everything from the internet. This improves speed and reduces data usage.
You can view and manage this data by opening Chrome, tapping the three-dot menu, then going to Settings > Site settings. From there, you can check storage used by different websites and adjust permissions.
To delete site data, go to Settings > Privacy and security > Clear browsing data. Select Cookies and site data, choose a time range, and tap Clear data.
If you want to remove data for a specific site, go to Settings > Site settings > All sites, select the site, and tap Clear & reset.
Keep in mind that deleting site data may sign you out of websites and remove saved preferences.
For more private browsing, you can use Incognito mode, where Chrome does not save site data after you close all incognito tabs.
