How to Clear Local Storage for a Website or Extension in Google Chrome

Chrome

Websites and extensions in Chrome often store data in an area called local storage which you may want to occasionally clear. Follow this guide to do so.

Websites store data locally on your computer, in the form of cookies, cache, and local storage. This is to help enhance your browsing experience, avoiding the need to always sign in or constantly download the full contents of a page every time you load it.

However, there might be situations when you need to clear this data, perhaps to resolve website issues or to maintain your privacy. You can do this by clearing the local storage for a website in Google Chrome. This will wipe any saved data Chrome has for the website you’ve visited.

To clear local storage for a website or browser extension in Google Chrome, follow the steps below.

What is Local Storage in Google Chrome?

Local storage in Google Chrome allows websites to store data in your browser, making it possible for complex web applications to work. Unlike cookies, which are limited in size and can only store text, local storage allows browsers like Chrome to store large amounts of data, including complex data types like objects and arrays.

When you visit a website, it may use local storage to save your preferences, keep track of your browsing history or even store entire web pages for a faster browsing experience. This storage method ensures that the data is available even when you’re offline, making the web application more reliable and consistent from your perspective.

Diving deeper into local storage, Chrome has specific ways to manage this data. One of these methods is chrome.storage.local, an API provided by Google Chrome that allows browser extensions to store and retrieve data. This API is designed for extensions—your data stored using chrome.storage.local remains private, accessible only by the extension that created it.

Local storage offers more functionality compared to cookies and can work with complex data types. If you’re worried about your privacy, however, you might need to remove it.

Once you’ve cleared the local storage data, your extension will be clear of any local data that it’s previously accumulated. This will include login information, so you may need to sign in again if the extension requires authentication to use.
