Documents you create using websites, such as calendars or journals, are sometimes stored on your hard disk in the form of databases. You can view and remove these databases, and set a maximum amount of disk space for them.
To view databases:
Choose Safari > Preferences and click Security.
Click Show Databases.
To modify the space allocated for databases:
Choose Safari > Preferences and click Security.
From the “Database storage” pop-up menu, choose the amount of space a database is initially allowed to occupy.
If a website needs additional space, a message appears.
To remove databases:
Choose Safari > Preferences and click Security.
Click Show Databases.
Select one or more databases and click Remove, or click Remove All.
Important:If you remove a database, all the information in it is removed. Your website service may not be able to retrieve your information.
