Forget Me Now Extension

--- Clear Browsing Data Automatically ---
No longer worry about Cross-Site Tracking as Forget Me Now will clear all of your browsing data (cookies, IndexedDB, local storage, session storage, service workers, Web SQL) for a site automatically upon closing the last open tab for that specific site. By default automatic clearing of browsing data is enabled for all sites.

● Visit any site (https://mail.google.com)
○ Extension by default will be enabled on all sites
○ Extension icon will be blue to indicate that browsing data clearing is enabled for the active tab's domain (*.google.com)
● Close the last open tab for a site within the same domain (drive.google.com or *.google.com)
● Extension will clear all browsing data, except for cache by default, for all of the sites visited within that same domain (mail.google.com & drive.google.com)
● Extension by default will create a Chrome notification to indicate which sites browsing data are being cleared and allow you to opt to not clear data that time
○ Disable Clearing Site Data Notifications
■ Right-click icon
■ Select 'Global Options'
■ Uncheck 'Notify Before Clearing Data'
■ This is a global option and will be saved in Chrome's sync storage for later recall (set it and forget it even across computers)

■ Select 'Global Options'
■ Check 'Clear Cache on Clearing Data'
■ This is a global option and will be saved in Chrome's sync storage for later recall (set it and forget it even across computers)

--- Privacy Policy ---
As Forget Me Not is in the business of protecting your privacy we believe the best way to prevent the sale or sharing of your data is to never collect it in the first place, that is why we attest that we do not collect a scintilla of your data, not your usage of our extension, not of the sites you use our extension with, not of anything at all, and further we promise to never collect any unique user data at any time in the future.

--- Examples of Data Stored ---
All of your site and global options are stored securely within Chrome’s sync storage which is tied to the Google account you are using with Chrome, and can only be accessed by the extension itself and cannot be retrieved via a cross-site scripting (XSS) attack. The benefit of using sync storage is that these stored options travel with you on any computer that you install Forget Me Not on, don’t worry, your options are automatically cleared if you decide to uninstall the extension.
