Memory cleaning is designed to delete sensitive data from the temporary memory on your BlackBerry® device. Examples of sensitive data include sensitive data in the cache for the key store browser, unencrypted data from email messages, LDAP authentication passwords and data from certificate and key searches.

When memory cleaning is turned on, the memory cleaning application is designed to delete sensitive data automatically in the following situations:

• when you insert your device in a holster
• when you do not use your device for a specified period of time
• when you synchronise with your computer
• when you change the time or the time zone for your device
• when you lock your device
